| characterization of two new serotypes of san miguel sea lion virus. | two new virus isolates, one from a california sea lion (zalophus californianus californianus) and the other from a northern fur seal (callorhinus ursinus) were partially characterized. their physicochemical characteristics were similar to those of vesicular exanthema of swine virus (vesv) and san miguel sea lion virus (smsv). the virion morphology was in both instances typically calicivirus. on the basis of this and the serum cross-neutralization testing, these isolates were classed as two new t ... | 1977 | 67101 |
| immunohistochemical study of a large molecular fragment of thyroglobulin in parafollicular cells. | thyroglobulin-like immunoreactivity of the parafollicular cells was studied by an immunoperoxidase bridge technique using antisera against dog thyroglobulin fragments. 1. the dog parafollicular cells were specifically stained by anti-peak i (27s and larger components fraction) antiserum absorbed with peak ii (19s fraction). by this method, they were easily distinguishable from the non-reactive follicular cells and colloid droplets. more sensitive staining of the parafollicular cells was possible ... | 1978 | 76516 |
| san miguel sea lion virus fed to mink and pigs. | mink became infected with san miguel sea lion virus when fed ground meat from seal carcasses showing vesicular-like lesions in the skin. the mink also contracted the infection when they were fed san miguel sea lion virus infected pig meat or cell culture propagated virus. san miguel sea lion virus infection in mink was inapparent but the virus was isolated from blood and rectal swabs. pigs treated similarly with the same virus preparations given to mink developed a severe vesicular disease syndr ... | 1978 | 96925 |
| urinary chorionic gonadotropin levels in pregnant golden lion tamarins. preliminary observations. | we have established the interval over which urinary chorionic gonadotropin can be detected by a radioimmunoassay during pregnancy in the golden lion tamarin. preliminary findings indicate the potential value of this radioimmunoassay system for (1) diagnosis of pregnancy at about four weeks after fertilization; (2) estimation of the expected time of delivery; and (3) identification of individual monkeys having an apparent high risk of spontaneous abortion. | 1978 | 110938 |
| description and analysis of the arch display in the golden lion tamarin, leontopithecus rosalia rosalia. | three different arch displays are described in captive lion tamarins (leontopithecus rosalia rosalia) at the national zoological park. analysis of social behaviours including huddling, sexual activity, territorial encounters and arch displays suggests that arch displaying is motivated by conflicting tendencies of a nonaggressive nature and may function as a regulator of social contact, thus maintaining homeostasis within and between a social group. | 1979 | 118906 |
| effects of drugs influencing serotonergic mechanisms on behaviour of insects. | the present paper deals with effects of some drugs affecting brain serotonergic mechanism on behaviour in cockroach (periplaneta americana) and immature form (larvae) of ant lion (myrmeleon formicarius). the effects of para-chlorophenylalanine, lsd-25 and 5-htp on simple learning mechanisms in cockroach and on behaviour of ant lion (building the funnel-shape traps) were studied. both p-chlorophenylalanine and lsd-25 facilitated behaviour of insects whilst 5-htp delayed responses. our experiments ... | 2013 | 138133 |
| [electron microscopy of human nasal mucosa in disturbances of the autonomic nervous system. i. sympathetic denervation (author's transl)]. | the fine structure of the human nasal mucosa is described shortly after unilateral stellate gang-lion blockage as well as in a case of sympathetic denervation of four weeks duration. for the clinical picture, corresponding to vasomotor rhinitis, there is a characteristic fine structural correlation consisting of dilatation and increased permeability of the vessels as well as stimulation of the nasal glands. in the glands, both increased activity and degenerative changes suggesting "secretory exh ... | 1977 | 139514 |
| observations on the infectivity of parasitic third-stage larvae of uncinaria lucasi stiles 1901 (nematoda: ancylostomatidae) of northern fur seals, callorhinus ursinus linn., on st. paul island, alaska. | twelve fur seal pups, which had not nursed their mothers, were used in an infectivity experiment. pups were exposed to parasitic 3rd-stage larvae of uncinaria lucasi from belly tissues of fur seal bulls, bachelors, and pregnant cows, to determine maturation capability of the larvae. hookworms were not recovered from the intestines of 3 pups receiving larvae from belly blubber of bulls, 6 pups receiving larvae from belly blubber of bachelors, and 1 nonexposed pup. maturation of hookworms did occu ... | 1978 | 149188 |
| a new calicivirus isolated from a marine mammal. | a new serotype of calicivirus, designated as san miguel sea lion virus type 6 (smsv-6), was isolated from vesicular lesions on the flipper of a california sea lion pup. serologic studies show that smsv-6 neutralizing antibodies (sn) occur frequently among california sea lions and occasionally among northern fur seals. feral swine, 1- to 6-week elephant seal pups and grey whales tested negative for smsv-6 antibody. | 1979 | 227346 |
| viruses and virus diseases of marine mammals. | poxvirus and several serotypes of calicivirus cause recognizable disease in marine mammals. pox lesions in pinnipeds are raised and proliferative and are seen most frequently after confinement in captivity. in cetaceans, a poxvirus is associated with a much more benign and chronic lesion called a "tattoo." numerous caliciviruses of differing antigenic types have been isolated from vesicular lesions and aborted fetuses of northern fur seals and california sea lions as well as from clinically norm ... | 1979 | 230170 |

| caliciviruses infecting monkeys and possibly man. | caliciviruses have, for the 1st time, been shown experimentally to infect a primate. twenty-four hours after being inoculated with san miguel sea lion virus (smsv), an african green monkey developed a febrile response and vesicular lesions at injection sites. virus was recovered from lesion material 96 hours later and from the stool at 48 hours. possible human infection with smsv was indicated by serologic evidence. three persons working with 4 distinct serotypes of smsv developed neutralizing a ... | 1978 | 415648 |
| plasma biochemical values of clinically-normal australian sea lions (neophoca cinerea). | seventeen biochemical constituents were assayed in the blood plasma of clinically-normal australian sea lions (neophoca cinerea). the sea lions formed part of a breeding colony which inhabits the southern coast of kangaroo island, south australia. little variation was found in any of the values obtained from animals of different age and sex. the results were compared with values published for california sea lions (zalophus californianus), northern fur seals (callorhinus ursinus), harbor seals (p ... | 1979 | 459034 |
| serum concentrations of oestradiol and progesterone during the normal oestrous cycle and early pregnancy in the lion (panthera leo). | during a 6-month study period weekly serum samples demonstrated 9 oestradiol surges above 14 pg/ml (range 19-108 pg/ml) among 3 lionesses isolated from male lions. intervals between peaks ranged from 3 to 8 weeks. progesterone surges of more than 17 ng/ml (range 17-282 ng/ml) and lasting for 2-6 weeks were recorded after 7 of the oestradiol peaks. sexual behaviour correlated well with the oestradiol peaks. except for cornification following oestradiol peaks, there was no obvious vaginal cytology ... | 1979 | 513015 |
| immobilisation of free-ranging galapagos sea lions (zalophus californianus wollebaeki). | nine free-ranging galápagos sea lions were immobilised for marking, using a combination of ketamine (3 to 5 mg per kg) and xylazine (0.5 to 1.0 mg per kg). the degree of effect depended largely on the animals' behavioural and physiological state before immobilisation (after parturition, high arousal, subject to aggression, etc.) all nine animals survived. overheating in the immobilised state may quickly result in heart and circulatory failures. | 2004 | 516341 |
| acute viral hepatitis in california sea lions. | acute viral hepatitis was diagnosed in five california sea lions (zalophus californianus) stranded along the los angeles coast. light microscopy revealed large nuclear inclusion bodies in hepatocytes. electron microscopy provided evidence that these inclusion bodies were composed of adenovirus-like virions. attempts to grow the virus in cell culture systems were unsuccessful. | 1979 | 521373 |
| salmonellae in feral pinnipeds off the southern california coast. | rectal swabs were collected from 90 northern fur seal (callorhinus ursinus) and 50 california sea lion (zalophus californianus) pups on san miguel island for salmonella screening. three serotypes (newport, heidelberg, and oranienburg) were recovered from 33% of the fur seals and 40% of the sea lions. | 1979 | 522219 |

| host range comparisons of five serotypes of caliciviruses. | two new serotypes of san miguel sea lion virus (smsv), designated smsv-4 and smsv-5, were studied in vivo and in vitro. the host cell spectrums were compared with smsv-1, smsv-2, and vesicular exanthema of swine virus type a-48. based on the result of these broad host spectrums, a numerical scoring system was devised for ranking each virus on the basis of its potential for infecting terrestrial mammals, including the important domestic species. | 1977 | 556918 |
| rna synthesized in calicivirus-infected cells is atypical of picornaviruses. | rna labeled with [3h]uridine from vero cells infected with san miguel sea lion virus in the presence of actinomycin d was analyzed by glycerol density gradient sedimentation and polyacrylamide gel electrophoresis. the predominant single-stranded rna (36s, 2.6 x 10(6) molecular weight) was genome size. there was also a prominent 22s, 1.1 x 10(6)-molecular weight, single-stranded component and one or more double-stranded or partially double-stranded classes. replicative forms, sedimenting at 18s, ... | 1977 | 559106 |
| relationship of san miguel sea lion virus to other members of the calicivirus group. | san miguel sea lion virus (smsv) is indistinguishable from vesicular exanthema virus (vev) and feline calicivirus (fcv) in its morphology and in possessing a single capsid polypeptide with a molecular weight of approximately 65 x 10(3). neutralization tests readily differentiate the three viruses, but immunodiffusion tests show that smsv is closely related serologically to vev but not to fcv. although the rnas of the three caliciviruses have similar base compositions, homology tests show that sm ... | 1978 | 564894 |
| parasites and associated pathology observed in pinnipeds stranded along the oregon coast. | forty-two seals and sea lions found dead along the oregon coast were examined for parasites and associated pathology. nematode infections of the lung and/or gastrointestinal tract were the primary cause of death in 5 of 42 animals examined. new distribution records were established for pricetrema zalophi and zalophotrema hepaticum. new host records include z. hepaticum and diphyllobothrium cordatum in the steller's sea lion (eumetopias jubatus); nanophyetus salmincola in the california sea lion ... | 1978 | 567698 |
| immunoelectron microscopic comparisons of caliciviruses. | using immunoelectron microscopy, 9 serotypes of vesicular exanthema of swine virus (vesv) were compared with 5 serotypes of san miguel sea lion virus and 7 additional calicivirus isolates from marine animals. in addition, swine caliciviruses and marine caliciviruses were compared with the vaccinal strain of feline calicivirus (fcv) f-9. of 9 vesv types, 8 showed common antigenicity with san miguel sea lion virus. of 9 vesv types, 2 showed common antigenicity with fcv f-9. all 12 marine calicivir ... | 1978 | 567950 |
| comparative resistance of san miguel sea lion virus and vesicular exanthema of swine virus to chemical disinfectants. | two similar calici agents, san miguel sea lion virus (smsv) and vesicular exanthema of swine virus (vesv) are susceptible to the virucidal activity of disinfectants of differing formulation. ten of 12 compounds were effective against six log10 plaque forming units (pfu) of smsv in a 2-min exposure at 4, 25 and 37 degrees c. however, only seven of these 10 smsv-positive compounds inactivated vesv under the same conditions of temperature and time. two compounds were not effective against smsv in a ... | 1978 | 568301 |

| isolation of edwardsiella tarda from three oregon sea mammals. | edwardsiella tarda was isolated from the peritoneal exudate of a steller's sea lion (eumetopias jubata) with peritonitis resulting from a perforating colonic ulcer; from the liver of a harbor porpoise (phocena phocena) with metritis and peritonitis sequela to dystocia; and from the liver of a california sea lion (zalophus californianus) with peritonitis following fracture and necrosis of a lumbar vertebrae. these findings indicate e. tarda is a common opportunistic invader in sick or injured mar ... | 1978 | 691128 |
| pancreatic duct adenoma and strangulation of the small intestine in a california sea lion (zalophus californianus). | a 16 year-old female california sea lion (zalophus californianus) died in a zoological garden following a period of insidious weight loss. necropsy revealed a loop of intestine strangulated by a fibrous ring connected to a pancreatic mass. histopathologic diagnosis of the latter was pancreatic duct adenoma. | 1978 | 739584 |
| vesicular exanthema of swine. | vesicular exanthema of swine (ves) was first recognized in 1932. at the time, eradication measures and, later, quarantine procedures were instituted and extension of the disease to surrounding farms appeared to have been prevented. between 1932 and 1936, however, seemingly unrelated epizootics continued among swine herds being fed raw garbage. in 1936, ves disappeared only to reappear in 1939. the disease was contained within california until 1952, at which time it spread to all the major swine ... | 1976 | 786969 |
| vesicular exanthema of swine and san miguel sea lion virus. | san miguel sea lion virus (smsv), recently isolated from marine mammals, and vesicular exanthema of swine virus (vesv), which caused epizootics of vesicular exanthema of swine (ves) over a period of 24 years (1932 to 1956), may be the same virus. this finding is of particular interest because the source of the original ves epizootic was never identified, swine were the only known natural host of vesv, and vesv was thought to have been eradicated. the smsv has been shown to be enzootic in 2 speci ... | 1976 | 786970 |
| nodular suppurative cutaneous cellulitis in a galapagos sea lion. | necropsy was performed on a sea lion (zalophus californianus wollebaeki), sacrificed in an advanced (pre-terminal) stage of disease, possibly represenatative of the galapagos epizootic of 1970-71. predominant features of the disease were nonumbilicated multiple suppurative cutaneous nodules, debilitation and loss of motor power. histopathological studies of the skin lesions disclosed suppurative cellulitis, with leucocytic invasion extending, in some instances, to all layers of the epidermis. ps ... | 1975 | 807749 |
| some important parasitic and other diseases of lion, panthera leo, in the kruger national park. | lions in the kruger park have been found affected by a variety of parasitic and other disease conditions, including trichinosis, filariasis, sarcoptic mange, pentastomiasis, echinococcosis, taeniasis, hepatozoonosis, anthrax, babesiosis and rickets. six of these may be directly or indirectly transmissible to man or are, at least, closely related to human parasites or disease. nine of these diseases, or closely related conditions, are also known to infect domestic animal species. the opposite may ... | 1975 | 811797 |
| [mercury pollution of the superficial sediments of the gulf of lion]. | mercury pollution in the superficial sediments of the continental shelf of the golfe du lion, is characterized by an important extension in its eastern part, which is under the direct influence of the rhône river, and more limited and fragmented in itw western part. between both these zones, territories with low contamination persist, of which the hydrodynamism prevents the advance of dense particles containing mercury. | 1975 | 813846 |
| premature parturition in the california sea lion. | twenty percent of the california sea lion pups born on san miguel island die due to premature parturition. specimens collected from premature-partus animals resulted in recovery of a virus, san miguel sea lion virus, indistinguishable from vesicular exanthema of swine virus, and leptospira pomona from some of the premature cows and pups. the age range of 10 females delivering healthy pups in june was 10-14 years. with one exception, the ages in 10 aborting females was 6-8 years. the p,p'-dde le ... | 1976 | 815567 |
| toxoplasmosis in a california sea lion (zalophus californianus). | disseminated toxoplasmosis was diagnosed in a female california sea lion that had been used in thermoregulation studies for about 4 years while housed in a small enclosure with a fresh-water pool at the university of hawaii, honolulu. toxoplasma gondii was demonstrated in and around necrotic lesions of the heart and the stomach. source of the infection was not established; however, studies on toxoplasmosis in cats were being conducted at the institution, and common caretakers attended both group ... | 1977 | 835862 |
| intratracheal injection of antibiotics in the california sea lion, zalophus californianus, and bottlenosed dolphin, tursiops truncatus. | gentamicin and cephaloridine were administered by intratracheal injection to the california sea lion, zalophus californianus, and the bottlenosed dolphin, tursiops truncatus. uptake and clearance of these antibiotics in the blood were monitored. in all cases, absorption through the respiratory mucosa resulted in blood levels approaching therapeutic concentrations despite low dosages. | 1977 | 839623 |
| structural correlates of forelimb function in fur seals and sea lions. | dissections, manipulation of ligamentary preparations, analysis of limb proportions, and quantitative aspects of forelimb myology are used to correlate forelimb morphology in fur seals and sea lions (sub-family otariinae) with previously published data as to their locomotor function (english, '76a). comparisons to structure and function in generalized fissiped carnivores are then used to elucidate locomotor adaptations in fur seals and sea lions. unique features of forelimb function during swimm ... | 1977 | 845968 |
| skull malformation and cerebellar herniation in captive african lions. | thickening of the cranial vault with a resulting cerebellar herniation is described in a series of litters of lion cubs, all with the same parents, one of whom was also very mildly affected. this animal, when mated to his daughter, also produced affected cubs. the aetiology of the condition is discussed and it is considered that vitamin a deficiency may have been less important than has been suggested by other authors. | 1977 | 847879 |
