instinctive predatory behavior of the ferret (putorius putorius furo l.) modified by chlordiazepoxide hydrochloride (librium). | the predatory behavior of ferrets (putorius putorius furo l.) consists mainly of instinctive behavioral patterns that are elicited by simple external stimuli. for the ferret, the time needed to catch and kill rats depends on the size of the rats in relation to that of the ferret. killing success decreases with a relative increase in prey size. chlordiazepoxide hydrochloride injections (1 mg/kg, i.m.) modified this behavior. drugged ferrets needed less time and less bites to kill relatively large ... | 1978 | 103120 |
trial of avermectin b1a, mebendazole and melarsoprol against pre-cardiac dirofilaria immitis in the ferret (mustela putorius furo). | avermectin b1a was found active against the pre-cardiac stage of dirofilaria immitis in ferrets. the drug was given orally, at 0.2 mg/kg, on days 38--42 of infection. at necropsy, 5 1/2 months after inoculation, worms were almost totally absent from the hearts of these ferrets. the efficacy of melarsoprol against developing dirofilaria, which has been demonstrated in dogs by other workers, was demonstrated in ferrets given oral doses, at 100 mg/kg, on days 38--42 of infection. the reported effic ... | 1978 | 739297 |
growth and development of the european ferret (mustela putorius). | body weight, body length, and other developmental parameters were studied in the european ferret, mustela putorius, from birth to 26 weeks of age. males and females did not differ in weight until the seventh week of live, and they did not differ in length until the ninth week of life, when the males began to grow faster. adult males (1400--1500 g) were heavier than adult females (800--900 g), but females reached adult size faster than males. | 1978 | 633841 |

[the ferret (putorius putorius furo), an additional final host of sarcocystis muris (author's transl)]. | two ferrets were fed mice experimentally infected with sarcocystis muris. after 7 days they excreted with their faeces for 9 days sporocysts which were morphologically indistinguishable from s. muris sporocysts. five mice which each received 70 of these sporocysts orally developed macroscopically visible cysts of s. muris in their musculature after 4 months. | 1979 | 107667 |
the ferret, mustela putorius furo, as a new species in toxicology. | comprehensive studies on the haematology, urine chemistry, serum chemistry and gross pathology have been carried out and reported. seasonal weight changes were confirmed and were initiated, together with sexual activity, when ferrets were brought in to a constant temperature (18-19 degrees c) and 14-hour daylight cycle during the winter months. levels of haemoglobin, erythrocytes and haematocrit were higher than in most common laboratory species. similarly, serum electrolytes and glucose levels ... | 1979 | 480899 |
anaesthesia of the ranch mink (mustela vison) and ferret (mustela putorius furo). | 1979 | 538879 | |
some aspects of the physiology and anatomy of the cardiovascular system of the ferret, mustela putorius furo. | the resting heart rate was monitored in 50 urethane-anaesthetized (387 +/- 54 beats/min) and 4 conscious (341 +/- 39 beats/min) ferrets. the arterial blood pressure in the anaesthetized animals was 140/110 +/- 35/31 mmhg. the circulatory responses to vagal stimulation, carotid artery occlusion and a variety of humoral agents were examined. the vagal innervation of the heart and of the distribution of the great vessels are described. | 1979 | 553192 |
urolithiasis in ferrets (mustela putorius). | urinary calculi was observed frequently in ferrets which were from a group used for influenza research. they were submitted for necropsy with various clinical signs. the calculi were composed of magnesium ammonium phosphate hexahydrate and were found in the pelvis of the kidney, urinary bladder and urethra. crystals of undetermined nature occasionally were observed in the kidneys. | 1979 | 459421 |
suppression of maturation of dirofilaria immitis in mustela putorius furo by single dose of ivermectin. | 1980 | 6893467 | |
simple technique for bleeding ferrets (mustela putorius furo). | 3-5 ml of blood can be obtained routinely from the tail of a conscious ferret without affecting the wellbeing of the animal. the development of this technique makes the ferret more readily available as an alternative species for multidose toxicity studies. | 1980 | 7359890 |
smooth-muscle hyperplasia and neoplasia in the ovaries of domestic ferrets (mustela putorius furo). | twenty cases of ovarian leiomyoma in a colony of ferrets are described. the tumour appears to be relatively frequent in this species which is in general noted for its lack of susceptibility to spontaneous and induced neoplasia. | 1980 | 7400878 |

secretion of monovalent ions and water in ferret salivary glands: a micropuncture study. | the acinar mechanisms of secretion of the monovalent ions, na+, k+, cl-, and hco3-, and water in the parotid and submandibular glands of the ferret, mustela putorius furo, were investigated using micropuncture and microanalytical techniques during salivation induced by pilocarpine. the osmolarity and monovalent ionic composition of the primary secretory fluid obtained from the intercalated ducts of these glands were determined. | 1981 | 6937508 |
transductal fluxes of water and monovalent ions in ferret salivary glands. | the net transductal fluxes of water and monovalent ions were measured in the parotid and submandibular salivary glands of the ferret, mustela putorius furo, during stimulation of secretion with pilocarpine. the duct systems of these glands were found to be impermeable to water using the split-oil droplet method for stationary microperfusion of lobular and main ducts. the net transductal fluxes of na+, k+, cl-, and hco3- were characterized by analysis of ductal fluid samples obtained simultaneous ... | 1981 | 6934197 |
feed consumption and food passage time in mink (mustela vison) and european ferrets (mustela putorius furo). | the amount of feed consumed per day and the rate of food passage was measured in mink and european ferrets. daily feed consumption averaged 40 and 42 g dry matter per kg body weight for male mink and ferrets and 53 and 49 g dry matter per kg body weight for female mink and ferrets, respectively. using ferric oxide as a feed marker, no differences were observed in food passage time between mink and ferrets or between males and females within each species. the mean time of food passage was 187 min ... | 1981 | 7265904 |
instinctive predatory behavior of mustelids (mustela putorius f. furo, mustela vison f. dom.) modified by benzodiazepine derivatives. | the predatory behavior of the ferret and of the mink consists mainly of instinctive behavioral patterns that are elicited by simple external stimuli. an important stimulus is size of the prey; the time needed to catch and kill defensive prey depends on the size of the prey in relation to that of the predator. benzodiazepine derivatives like chlordiazepoxide or lorazepam affect the prey catching of both species significantly. drugged animals (2 mg/kg orally) need less time to overpower their prey ... | 1981 | 6113610 |

experimental trichinella spiralis infection in the ferret, mustela putorius furo. | laboratory ferrets (mustela putorius furo) were each inoculated with 500 larvae of a strain of trichinella spiralis that had been passaged in mice for many generations. the recovery of adult worms from ferrets on days 4 and 7 of infection represented a mean of 32% of the inoculum, with most of the worms being in the anterior three quarters of the small intestine. larvae subsequently became encysted in the ferret musculature, with the diaphragm alone yielding as many as 5,750 larvae upon digestio ... | 1982 | 7069183 |
respiratory mechanics of a small carnivore: the ferret. | the ferret, mustela putorius furo, is a small relatively inexpensive carnivore with minimal housing requirements. measurements were made from anesthetized tracheotomized supine males. values obtained during tidal breathing for six animals (576 +/- 12 g) were as follows: tidal volume, 6.06 +/- 0.30 ml; respiratory frequency, 26.7 +/- 3.9 breaths min-1; dynamic lung compliance, 2.48 +/- 0.21 ml cmh2o-1; pulmonary resistance, 22.56 +/- 1.61 cmh2o . l-1 . s. pressure-volume curves from nine ferrets ... | 1982 | 7085416 |
proliferative colitis in ferrets. | during a 4-month period, 31 of 156 ferrets (mustela putorius) in a biomedical research program developed protracted diarrhea. clinical signs were green mucohemorrhagic fecal material, partially prolapsed rectum, anorexia, body weight loss, and dehydration. nine of the affected animals were necropsied. on gross examination, the descending colon was grossly thick and histologically characterized by marked proliferation of the mucosa, relatively few goblet cells, mixed inflammatory cell infiltrate, ... | 1982 | 7091850 |
the ferret (mustela putorius furo) as an experimental host for brugia malayi and brugia pahangi. | ferrets inoculated subcutaneously with 150--200 infective larvae of brugia malayi (subperiodic strain) usually developed patent infection during the 3rd month post inoculation. microfilaremia was transient, and most animals became amicrofilaremic after the 6th month of infection. ferrets developed a persistent eosinophilia at the time of patency. at necropsy, 5--8 months post infection, adult worms were recovered principally from lymphatic vessels and recovery ranged from 0.5--13% of the inocula ... | 1982 | 7102908 |
electrophoretic variation in large mammals. ii. the red fox, vulpes vulpes, the stoat, mustela erminea, the weasel, mustela nivalis, the pole cat, mustela putorius, the pine marten, martes martes, the beech marten, martes foina, and the badger, meles meles. | 1982 | 7107306 | |
haematological and serum chemistry profiles of ferrets (mustela putorius furo). | female, male and castrated male ferrets were studied. weight gain plateaued at 28 weeks of age with males about 500 g heavier than females. no statistically significant differences in haematology were observed with age, but alkaline phosphatase and alanine aminotransferase levels fell while glucose increased. haemolysis led to various changes including marked increases in total protein, albumin, inorganic phosphate and sorbitol dehydrogenase. | 1982 | 7078059 |
excretion and placental and mammary transfer of hexachlorobenzene in the european ferret (mustela putorius furo). | female european ferrets (mustela putorius furo) absorbed 98.5% of a single dietary exposure of hexachlorobenzene (hcb). the hcb was found to readily cross the placenta and to be excreted in the milk of pregnant/lactating ferrets. after consuming hcb-treated feed, ferrets raising offspring excreted 50% of the initial dose by 32 d, while unbred ferrets achieved this same degree of hcb elimination in 41 d. the percentages of hcb excreted via the urine and feces were approximately 5 and 45%, respect ... | 1982 | 7161840 |
isolation of mycoplasmas from experimental ferrets (mustela putorius). | a total of 21 apparently healthy experimental ferrets, 8 males and 13 females, comprizing 1, 2 and 3 year-old animals were examined for mycoplasmatales. mycoplasmas were isolated from 17 samples of 21 oral cavities (81.0%), and from 2 of 21 nasal cavities (9.5%), but not from the prepuce or vagina of the animals. neither ureaplasma nor acholeplasma was demonstrated in any of the locations of the ferrets examined. these mycoplasma strains proved to metabolize glucose but not arginine and urea. th ... | 1982 | 7169088 |
the developing ferret palate--a scanning electron microscope study: i. primary palate and secondary palatal shelves. | palatogenesis was studied in the ferret (mustela putorius) from day 27 to day 29 of gestation. at day 27 the primary palate is present as a flattened shield area, and the two secondary palatal shelves are directed at 45 degrees to the horizontal plane, passing downward on the lateral sides of the tongue, which occupies the space between them. by day 28 the primary palate is bulging convexly in the oral cavity, and the secondary palatal shelves have elevated and are in contact in the midline. fin ... | 1982 | 7174774 |
carbonic anhydrase activity of intact erythrocytes from seven mammals. | carbonic anhydrase activity of intact erythrocytes from seven mammalian species was determined at 25 degrees c, ph 7.4, by mass spectrometry using the 18o-exchange technique. the seven species were cavia porcellus, mustela putorius furo, felis domesticus, canis familiaris, homo sapiens, equus caballus, and bos taurus. carbonic anhydrase activities determined as a function of hemoglobin concentration (std kcat) for intact erythrocytes at ph 7.4 were not significantly different from those determin ... | 1983 | 6415018 |
thermoregulation of polecat and raccoon dog: a comparative study with stoat, mink and blue fox. | 1. oxygen consumption (ml x kg0.75 per min) in relation to ambient temperature (ta) in the raccoon dog (nyctereutes procyonoides), polecat (mustela putorius), mink (mustela vison) and stoat (mustela erminea) is described by equations y = 14.2 - 0.23x, y = 26.3 - 0.47x, y = 26.9 - 0.33x and y = 39.0 - 1.06x, respectively. resting metabolic rate (rmr) of blue fox (alopex lagopus) could be measured only at thermoneutrality. 2. in polecats, calorigenic response to noradrenaline was about 40% above t ... | 1983 | 6131765 |
fetal alcohol syndrome in the ferret (mustela putorius). | gastric intubation of 1.5 g ethanol/kg maternal body weight produced a significant teratogenic response in ferrets (mustela putorius) treated once daily from gestational days 15 through 35. this response was evident by a rise in the frequency of fetuses with one or more malformations (21%), and by a rise in the frequency of litters with one or more malformed fetuses (50%). palatoschisis and greater relative intermedial canthi distance observed in this study are diagnostic features of the fetal a ... | 1984 | 6495223 |
retro-orbital technique for blood collection from the ferret (mustela putorius furo). | blood samples were obtained from anesthetized ferrets of various ages, by venipuncture of the retro-orbital plexus with a heparinized capillary pipette. it is recommended that a cumulative collection of 20% of total blood volume not be exceeded for any two week period. this technique, when carefully performed on alternate orbits and at a frequency dictated by body weight and volume of blood needed, has been used repeatedly for months without apparent harm or distress to the animal. | 1984 | 6727294 |

polyunsaturated fatty acid and peroxide levels in rations for fitch (mustela putorius furo). | 1984 | 16031027 | |
systemic candidosis in a fitch. | a 4-month-old fitch (mustela putorius furo) was presented vomiting and with a haemorrhagic enteritis that failed to respond to antibiotic, vitamin and fluid therapy. at necropsy, apart from lesions referable to an enteritis, no other specific abnormality was observed. histopathologically, lesions were seen in myocardium and renal medulla associated with mycelia, pseudomycelia and blastospores. marked lymphoid depletion was noted in lymph nodes and spleen. candida tropicalis was isolated from liv ... | 1984 | 16031078 |
pharmacokinetics of ethanol in the ferret. | select doses of ethanol (25%, w/v) were administered to female ferrets (mustela putorius) by gastric intubation to determine dosage corresponding to peak blood alcohol levels (bal) greater than 100 mg/100 ml of blood (mg%) for an extended duration. low doses (6 ml/kg) resulted in peak bal of 202 mg% in 1.5 hr and 50 mg% after 12 hr. intermediate doses (8 ml/kg) resulted in peak bal of 253 mg% in 1.4 hr and 89 mg% after 12 hr. high doses (12 ml/kg) did not increase peak bal proportionately, resul ... | 1985 | 3890594 |
use of ferrets in studies of the visual system. | the ferret (mustela putorius furo) is proving to be an excellent experimental animal for many anatomical and physiological studies of the adult and developing visual system. as a result, the amount of data available on the ferret's visual system is increasing at a rapid rate. the purposes of this paper are to briefly review some of those data and to present some of the reasons why the ferret is an appropriate choice as an experimental animal for visual system studies. | 1985 | 3894786 |
a comparative study of the tapetum, retina and skull of the ferret, dog and cat. | results of this investigation indicate that the ferret (mustela putorius) closely resembles the dog (canis familiaris) and should be a useful research animal alternative. the tapetum lucidum is a common structure present in the eyes of dogs, cats (felis catus) and other nocturnal animals. our study showed that this structure was present in ferret eyes. the color or reflection of the ferret and dog tapetum was remarkably reduced by the general fixation with glutaraldehyde. however, this color fad ... | 1985 | 4021435 |
adrenalectomy in the ferret. | a simple adrenalectomy technique is presented for the ferret (mustela putorius furo). the adrenal glands were removed in two operations with an interim recovery period of approximately 1 week. the right adrenal should be removed first, as the surgery is complicated on that side by fascia which binds the adrenal to the inferior vena cava. salt solution (1% nacl) in place of water will maintain sodium balance. | 1985 | 4021440 |
brugia malayi: intravenous injection of microfilariae in ferrets as an experimental method for occult filariasis. | microfilaremia, immune responses, and pathology were compared in ferrets infected with 100 third-stage larvae of brugia malayi (subperiodic strain) or injected intravenously with 10(6) microfilariae. ferrets (mustela putorius furo) inoculated with third-stage larvae typically became patent during the third month after infection, with a mean patency of 123 +/- 25 (se) days. ferrets injected intravenously with microfilariae exhibited a relatively constant microfilaremia for 3-4 weeks and usually c ... | 1985 | 4029349 |
wheel-running during anoestrus and oestrus in the ferret. | wheel-running activity was studied in female ferrets (mustela putorius furo), during periods of anoestrus and oestrus, as well as after gonadectomy. during anoestrus wheel-running was restricted to the hours of illumination, but during oestrus extended into the dark period and was increased overall, with the number of wheel revolutions being doubled or trebled. in spayed females wheel-running was mostly limited to the light periods. | 1985 | 4041057 |
spontaneous plasma cell myeloma in a ferret (mustela putorius furo). | 1985 | 4049681 | |
effect of exposure to 500 ppm sulfur dioxide on the lungs of the ferret. | male ferrets (mustela putorius furo) were exposed 3 h/day, 3 days/week for 12 weeks to 500 ppm so2. determinations were made of airway responsiveness by producing histamine dose-effect curves. lung tissues were fixed and studied by light and electron microscopy. epithelial cells of the trachea and bronchus were most affected. lesions observed included changes in ciliated cells, edema and cell infiltration. the most responsive animals to histamine were 2 from the exposed group. nasal discharge an ... | 1985 | 4081352 |
the electrocardiogram of normal ferrets and ferrets with right ventricular hypertrophy. | sixty-eight electrocardiograms were recorded on ferrets (mustela putorius furo). these represent 29 normal weanling males, 19 normal adult males and 20 adult males with right ventricular hypertrophy (rvh). analyses of rate, rhythm, axis and total voltage were used to define the normal electrocardiogram (ecg) and to identify changes seen in rvh. the normal ferret has a heart rate of about 300 beats per minute and a mean electrical axis of + 86 degrees +/- 6.6 (sd). a 56% increase in right ventric ... | 1985 | 3160888 |
variability in milk composition of the domestic ferret (mustela putorius). | ferret milk composition was analyzed among individuals, over time, and across teat pairs. females differed in fat, protein, and lactose concentrations. protein and fat concentrations varied over the course of lactation. lactose was the only measured component which differed across teat pairs. | 1985 | 2863046 |
anal gland secretions of the stoat (mustela erminea) and the ferret (mustela putorius formafuro) : some additional thietane components. | two new thietanes,cis- andtrans-2-ethyl-3-methylthietane, have been identified in the anal gland secretion of the stoat, and 2-isopropyl thietane has been characterized from the anal gland secretion of the ferret. conflicting published data are reevaluated. | 1985 | 24310328 |
imprinting on prey odours in ferrets (mustela putorius f. furo l. ) and its neural correlates. | the effect of different feeding conditions during ontogeny was investigated in the carnivorous ferret. behavioral tests and cardiac responses towards known and unknown odours as well as food choice tests showed that in this species olfaction plays an important role for prey recognition. yet, the knowledge of the prey odours has to be learned during a sensitive phase which was found to exist between postnatal days 60 and 90. in adult ferrets, searching for prey can be elicited reliably by familia ... | 1986 | 24924694 |
seasonal changes in energy economy of farmed polecat as evaluated by body weight, food intake and behavioural strategy. | an analysis of seasonal changes in energy budget of the farmed polecat (mustela putorius) was performed in subarctic climate. cyclical variations were found in the body weight of male polecats from maximum values in february (2.1 kg) to minimum values in june-july (1.5 kg). there were only minor seasonal changes in the body weight of females. there was a direct relationship between body weight and voluntary energy intake on one hand (r = 0.89) and an inverse relationship between body weight and ... | 1986 | 3774908 |
ammonia levels in the whelping nests of farmed raccoon dogs and polecats. | ammonia concentrations were measured in the nests of farmed raccoon dogs (nyctereutes-procyonoides gray, 1834) and polecats (mustela putorius) at weaning time. ammonia levels in the nests of raccoon dogs and polecats varied from 1 to 43 ppm and from 0 to 5 ppm, respectively. in the raccoon dog, with increasing litter size, the ammonia concentrations tended to increase exponentially. in the polecat, no marked relationship between litter size and ammonia levels were found. the results show that no ... | 1986 | 2871979 |
representation of the cochlea in primary auditory cortex of the ferret (mustela putorius). | in seven barbiturate-anesthetized ferrets, we explored the acoustically sensitive cortex with conventional microelectrode mapping techniques. a tonotopically organized field was found whose orientation was such that high tonal frequencies were represented dorsally, and low frequencies ventrally. within this field, neurons typically had short (12-20 ms) latent periods to first spikes. in conjunction with extant anatomical evidence on the connectivity of this region, these data suggest that this f ... | 1986 | 3771373 |
basal n-nitrosoproline formation and excretion in the ferret. | quantitative balance studies indicated that ferrets (mustela putorius furo) on purified diets excreted approximately four times more n-nitrosoproline than they ingested. this basal n-nitrosoproline excretion was not dependent on dietary nitrate intake, as high levels of dietary [15n]nitrate did not result in the incorporation of 15n into the excreted n-nitrosoproline. this indicates that there are at least two sources of endogenous n-nitrosoproline formation, one linked to dietary nitrate and on ... | 1986 | 3781434 |
hearing in the ferret (mustela putorius): thresholds for pure tone detection. | thresholds for pure tone detection were determined for two male ferrets (mustela putorius) using standard behavioral testing procedures. both animals had a broad range of hearing comparable to that seen in other carnivores. the lower limit of hearing at 60 db spl was estimated from the average audiogram to be 36 hz, and the upper limit of hearing was 44 khz. the lowest thresholds were found in the region of 8-12 khz with both animals exhibiting sharp tuning at best frequency. | 1986 | 3793642 |
[parasitism of mustelidae by skrjabingylus petrovi: first report in western europe]. | a study of the sinuses parasites was carried out on 206 skulls of small mustelidae: mustela putorius (52), m. nivalis (17), m. erminea (13), martes foina (102), and m. martes (11) from eastern france. besides troglotrema acutum two skrjabingylus species (s. nasicola and and s. petrovi) were observed and s. petrovi described for the first time in france. | 1986 | 3813436 |
heterologous anti-progesterone monoclonal antibody arrests early embryonic development and implantation in the ferret (mustela putorius). | early embryo development and implantation were arrested in ferrets passively immunized with a mouse monoclonal anti-progesterone antibody injected intraperitoneally at 72 and 96 h post coitum (p.c.) or at 72 h p.c. only. in control ferrets injected with mouse serum or 0.9% nacl, implantation sites were found in all mated females; autopsies were carried out at day 14 p.c. a total of 34 unimplanted embryos were recovered from the reproductive tract of antibody-treated ferrets and none of these had ... | 1986 | 3944809 |
suspected foreign body peritonitis in fitch (mustela putorius furo). | a severe, fatal, exudative peritonitis was investigated in a flock of 100 breeding fitch mustela putorius furo. the presence of enteric flora within the lesions and steel spicules within the stomach contents suggested that this disease may have been caused by steel fragments perforating the intestine. scoring and pitting of a steel mincer plate used for food preparation consistent with the size and shape of the steel particles found in the stomach, further supported this hypothesis. there were n ... | 1986 | 16031296 |
a congenital toxoplasma-like disease in ferrets (mustela putorius furo). | approximately 30% of 750 neonatal farmed ferret kits died without observed clinical signs. the presence of multifocal necrosis associated with toxoplasma-like organisms in the liver, lung and heart suggested a diagnosis of toxoplasmosis. surviving animals from affected litters were stunted but showed no histological or serological evidence of toxoplasma infection, nor could infection be demonstrated by mouse inoculation. the involvement of animals at one day of age indicated congenitally acquire ... | 1986 | 16031250 |
contribution of auditory cortex to sound localization by the ferret (mustela putorius). | ferrets were tested in a semicircular apparatus to determine the effects of auditory cortical lesions on their ability to localize sounds in space. they were trained to initiate trials while facing forward in the apparatus, and sounds were presented from one of two loudspeakers located in the horizontal plane. minimum audible angles were obtained for three different positions, viz., the left hemifield, with loudspeakers centered around -60 degrees azimuth; the right hemifield, with loudspeakers ... | 1987 | 3598629 |
campylobacter jejuni infection in the ferret: an animal model of human campylobacteriosis. | campylobacter infection in weanling ferrets (mustela putorius furo) was studied as an animal model for enteric campylobacteriosis in persons. the screening of fecal cultures on selective campylobacter media showed that campylobacter jejuni/coli was not present in the normal enteric flora. intragastric feeding of a mixture of cat feed and 2.5 x 10(8) c jejuni isolated from ferrets with naturally occurring proliferative colitis was accomplished. all ferrets (n = 8) became infected on 3 days after ... | 1987 | 3826848 |
variation of the ferret skull (mustela putorius furo l.) in relation to stereotaxic landmarks. | the ferret skull was investigated to identify reliable extracranial landmarks for stereotaxy. the skulls of 56 ferrets of both sexes were measured in a stereotaxic apparatus. neither body weight nor an index of skull length proved to be reliable predictors of intracranial location. sutures fused too early in life for lambda and bregma to be useful as landmarks in adult ferrets. the position of extracranial features was used to predict the position of intracranial features. for rostral intracrani ... | 1987 | 3328744 |
chondrosarcoma of the tail of ferrets (mustela putorius furo). | 1987 | 3603966 | |
reproductive state and motor activity in female ferrets. | the pattern of motor activity in female ferrets (mustela putorius furo) housed in cages mounted upon rocker platforms was followed under conditions of short-(8 hr) and long-(16 hr) day illumination. a distinct diurnal rhythm was evident that remained unchanged after lesioning of the anterior hypothalamus. the level of activity did not differ between animals kept under short days and long days, between anoestrous and oestrous females, or during the development or waning of oestrus. ovariectomy di ... | 1987 | 3671541 |

hypoglycaemia due to a functional pancreatic islet cell tumour (insulinoma) in a ferret (mustela putorius furo). | 1987 | 3037763 | |
intracellular free calcium concentration measured with 19f nmr spectroscopy in intact ferret hearts. | changes in the intracellular free ca2+ concentration, [ca2+]i, mediate excitation-contraction coupling in the heart and contribute to cellular injury during ischemia and reperfusion. to study these processes directly, we measured [ca2+]i in perfused ferret (mustela putorius furo) hearts using 19f nmr spectroscopy to detect the 5,5'-difluoro derivative of the ca2+ chelator 1,2-bis(o-aminophenoxy)ethane-n,n,n',n'-tetraacetic acid (bapta). to load cells, hearts were perfused with the acetoxymethyl ... | 1987 | 3112778 |
isolation of an atypical rotavirus causing diarrhea in neonatal ferrets. | a rotavirus was isolated from neonatal ferrets (mustela putorius furo) with diarrhea at a large commercial farm. this virus is classified as an atypical rotavirus, probably belonging to the group c rotaviruses. this classification is based on the lack of the rotavirus group a common antigen and on its distinct dsrna electropherotype pattern in polyacrylamide gels. the diarrheal disease was reproduced experimentally in neonatal ferrets. | 1987 | 3599884 |
serum cortisol radioimmunoassay values in the normal ferret and response to acth stimulation and dexamethasone suppression tests. | cortisol values were obtained from 39 ferrets, mustela putorius furo, by using a commercial radioimmunoassay. sera from 25 males (18 intact, 7 neutered) and 14 females (7 intact, 7 spayed) were assayed. resting serum cortisol values ranged from 0.13 to 2.70 micrograms/dl for males (mean = 0.93 +/- 0.63 micrograms/dl), and 0.55 to 1.84 micrograms/dl for females (mean = 0.86 +/- 0.29 microgram/dl). the resting cortisol values of both males and females were comparable to those of the cat (1.0 to 3. ... | 1988 | 2846957 |
dracunculus insignis: experimental infection in the ferret, mustela putorius furo. | the laboratory study of dracunculiasis has suffered from the lack of a suitable, readily available animal model. we have been able to experimentally infect ferrets. mustela putorius furo, with the north american dracunculid, dracunculus insignis. ferrets were inoculated with 75 to 100 infective larvae and were necropsied 90 to 240 days later. guinea worms were recovered from 10 (56%) of 18 ferrets. a total of 44 worms were recovered, for an average of 4.4 worms per infected ferret. gravid female ... | 1988 | 2973492 |
hearing in the ferret (mustela putorius): effects of primary auditory cortical lesions on thresholds for pure tone detection. | 1. pure tone thresholds were determined for five adult male ferrets before and after bilateral ablation of primary auditory cortex. complete audiograms ranging from 0.016 to 48 khz were obtained for two animals. the remaining three animals were tested at five frequencies selected to assess hearing throughout the audible range (0.125, 0.5, 2.0, 8.0, and 32.0 khz). 2. shortly after surgery one animal had elevated thresholds across the entire frequency range with the most pronounced hearing loss ab ... | 1988 | 3171665 |
antibody titers in domestic ferret jills and their kits to canine distemper virus vaccine. | antibody titers were measured in domestic or european ferret (mustela putorius furo) jills vaccinated with modified-live canine distemper virus (cdv) vaccine and in their kits. the half-life of maternal antibody to cdv in ferrets was 9.43 days. ferret kits should be vaccinated against cdv at 6, 10, and 14 weeks of age. | 1988 | 3182383 |
electrocardiographic values from clinically normal, anesthetized ferrets (mustela putorius furo). | electrocardiograms were recorded from 25 clinically normal male ferrets anesthetized with ketamine and xylazine and from 7 ferrets anesthetized with ketamine alone. ferrets anesthetized with ketamine alone had excessive salivation, open eyes, muscle tremors, muscle twitching, paddling motions, attempts to stand, and an unstable ecg baseline. because ketamine/xylazine combination resulted in induction and good muscle relaxation, the ecg had little interference resulting from muscular movement. | 1988 | 3247910 |
serum thyroxine and triiodothyronine radioimmunoassay values in the normal ferret. | the european ferret, mustela putorius furo, has become increasingly popular as an animal model in biomedical research. however, certain important normal clinical data have not been established for the ferret. in this study, serum thyroxine (t4) and 3,3',5-triiodothyronine (t3) values were obtained from ferrets by the use of commercial radioimmunoassays. sera from 44 animals, 31 males (27 intact and 4 castrated) and 13 females (10 intact and 3 spayed) were assayed. serum t4 values ranged from 1.0 ... | 1988 | 3184856 |
controlled cortical impact: a new experimental brain injury model. | a new experimental model of mechanical brain injury was produced in the laboratory ferret (mustela putorius furo) using a stroke-constrained pneumatic impactor. cortical impacts were made on vertex to the intact dura mater overlying the cerebral cortex with contact velocities ranging from 2.0 to 4.0 m/sec and with deformations of 2.0 to 5.0 mm. the dwell time of the impact and the stability of the skull during impact were verified with high speed (1000 to 3000 frames/sec) cineradiography. system ... | 1988 | 3193461 |
