role of the raccoon in the transmission of pseudorabies: a field and laboratory investigation.	serum samples were collected from 42 raccoons trapped in a pseudorabies enzootic area of missouri. all samples were negative for neutralizing antibodies to pseudorabies virus (prv). raccoons were orally exposed with one of four dose levels of prv. the raccoons were found to be susceptible to moderately large doses of prv tissue culture infective dose (10(4) - 10(5) tcid50). all raccoons given 10(3) tcid50 of prv survived and did not develop clinical signs. the prv was consistently isolated from ...	1980	6250423
on- versus off-responses of raccoon glabrous skin rapidly adapting cutaneous mechanoreceptors.	1. the on- and off-responses of 50 raccoon median nerve fibers associated with rapidly adapting cutaneous mechanoreceptors in glabrous skin were examined under experimental conditions designed to allow comparable opportunities for on- and off-responses to occur. trapezoidal stimuli were utilized, providing for equal stimulus indentation and retraction velocities and equal static displacement times and intertrial intervals. principal findings were as follows: 2. at stimulus levels well above disp ...	1980	6251178
possible role of wild mammals in transmission of pseudorabies to swine.	of 73 wild and domestic mammals tested from an area endemic for pseudorabies in swine, 16 showed natural pseudorabies virus infection, 8 from farms with no pseudorabies history. in transmission experiments with swine and raccoons (procyon lotor), pseudorabies was not transmitted between raccoons but was transmitted reciprocally between raccoons and swine by contact and when either consumed infected carrion of the other. the fluorescent antibody tissue section test proved valuable in diagnosis of ...	1980	6257934
acute idiopathic polyneuropathy in the dog.	from among a large group of dogs with acute tetraparesis, we identified 10 dogs with a distinct peripheral nerve disorder. prior to the onset of signs, all of the dogs had been healthy, and none was known to have been exposed to a neurotoxin or raccoon bite. weakness, with hypoactive or absent segmental reflexes, became progressively worse for 1 to 21 days. results of electromyography and nerve conduction studies invariably were compatible with a diagnosis of polyneuropathy that predominantly af ...	1981	6270046
the thalamic connectivity of the primary motor cortex (mi) in the raccoon.	the purpose of this study was to determine the pattern of thalamic projections of the primary motor cortex (mi) in the raccoon, a carnivore species noted for neural specialization of sensorimotor function. following electrophysiological identification of circumscribed regions of mi, injections of horseradish peroxidase (hrp) or hrp combined with tritiated amino acids were made in 15 animals. labeled thalamic cells were found predominantly in the ventral lateral nucleus (vl). for a given cortical ...	1982	6276451
pseudorabies virus infection in raccoons: a review.	pseudorabies is a rarely reported disease of raccoons. laboratory and field evidence of prv infection suggests the raccoon is a "dead end" host with little opportunity for raccoon-to-raccoon spread of virus. all reported field cases have been associated closely with infected swine and swine have been considered the source of the raccoon infection. the clinical signs of prv in raccoons closely resembles those of canine distemper and rabies virus infections. infection with the latter viruses are c ...	1982	6285008

electrophysiology of raccoon cuneocerebellar neurons.	electrophysiological experiments were undertaken in order to locate and functionally characterize cells of the raccoon main cuneate nucleus (mcn) that can be activated by electrical stimulation of the cerebellum. a total of 98 such units were studied in pentobarbital sodium-anesthetized, methoxyflurane-anesthetized, or decerebrate preparations. aside from a greater likelihood of resting discharge in the decerebrate preparations, no appreciable variability in physiological properties of the neuro ...	1984	6494666
brugia lepori sp. n. (filarioidea: onchocercidae) from rabbits (sylvilagus aquaticus, s. floridanus) in louisiana.	brugia lepori sp. n., a filarial nematode from the abdominal lymphatics and subcutaneous tissues of rabbits (sylvilagus aquaticus, s. floridanus), from st. tammany parish, louisiana, is described. brugia lepori is of moderate size (males 12 to 19 mm, females 39 to 45 mm) and within the genus most closely resembles brugia beaveri of the raccoon, from which it can be distinguished by its larger size, smaller spicules, and smaller microfilaria which has a shorter cephalic space. brugia lepori is on ...	1984	6502360
time-dependent changes in the functional organization of somatosensory cerebral cortex following digit amputation in adult raccoons.	surgical removal of the third forepaw digit in raccoons causes both long-term and short-term changes in functional organization within the digit 3 primary somatosensory (smi) cortex. previous studies have shown that 36-52 weeks following amputation in infant raccoons, neurons within the digit 3 cortical territory had become responsive to cutaneous stimulation of "new" forepaw regions adjoining the digit stump (carson et al., 1981; kelahan et al., 1980, 1981); the "novel" receptive fields (rfs) w ...	1984	6505463

geographic distribution of humans, raccoons, and white-footed mice with antibodies to lyme disease spirochetes in connecticut.	an indirect immunofluorescence test was used during 1982-1983 to identify antibodies to lyme disease spirochetes in humans, white-footed mice, and raccoons. serologic tests detected igm or total ig antibodies in serum samples from 67 persons. onset of illness, as marked by erythema chronicum migrans (ecm), occurred mainly during july and august. the majority of the persons with lyme disease lived in south central and southeastern connecticut. analyses also verified prior spirochetal infections i ...	1984	6516459
distribution of cerebellar mossy fibers arising from neurons of the raccoon main cuneate nucleus.	the present study demonstrates that fibers originating in the raccoon main cuneate nucleus are not segregated in specific cortical regions of target cerebellar folia as reported in studies of the cat cuneocerebellar tract. this observation supports the hypothesis that exteroceptive and proprioceptive divisions of the raccoon cuneocerebellar tract do not exist as distinct structural entities. the findings of this study do not preclude the possibility that projections from the external and main cu ...	1984	6525506
diagnostic features of zoonotic filariae in tissue sections.	the diagnostic features in tissue sections from patients with zoonotic filarial infections are reviewed. in general, two types of infections are recognized: 1) those presenting radiologically in healthy patients as coin lesions, which are usually removed because a clinical diagnosis of carcinoma of the lung is made and infarcts containing dirofilaria immitis parasites in pulmonary arteries are found; and 2) those presenting as subcutaneous nodules, in which d. tenuis, a parasite from raccoons, d ...	1984	6539296
antigenic characteristics of isolates associated with a new epizootic of raccoon rabies in the united states.	a panel of 23 monoclonal antibodies to the nucleocapsid protein of rabies virus was used to study the antigenic character of isolates of rabies virus from raccoons in the mid-atlantic region of the united states. comparison of the reaction pattern of these isolates with that of isolates of rabies virus collected from areas of major rabies outbreaks (skunk rabies in the midwestern united states, fox rabies in the northeastern united states, and raccoon rabies in the southeastern united states) su ...	1984	6539356
raccoon ascarid larvae (baylisascaris procyonis) as a cause of ocular larva migrans.	larvae of the common raccoon roundworm, baylisascaris procyonis, are known causes of visceral larva migrans and cns disease in animals and human beings. in the present experiments we examined the ability of b. procyonis to cause ocular larva migrans (olm) in subhuman primates, as an indication of its possible ocular zoonotic importance. squirrel monkeys given 5,000 or 10,000 infective b. procyonis eggs per os and cynomolgus monkeys given 20,000 eggs had clinical and histologic evidence of olm, b ...	1984	6541214

persistence of rabies antibody in free-ranging raccoons.	the immune status of a wildlife population to rabies virus probably influences the occurrences of epizootics among that species in a given geographical area. this is not to say that enzootic transmission of the virus will not occur, but rather that attainment of epizootic levels may be hampered through herd immunity. after an epizootic of rabies in a raccoon population in the fall of 1970, a serologic surveillance program was initiated from november 1970 through august 1974. the surveillance pro ...	1983	6619583
isolation of mycoplasma and ureaplasma species from raccoon dogs (nyctereutes procyonoides viverrinus).	mycoplasma spp. were isolated from five wild raccoon dogs (nyctereutes procyonoides viverrinus). on the basis of biochemical properties and serological tests, nine isolates were identified as mycoplasma edwardii and four were similar to a possibly new mycoplasma sp. represented by strain lm2 which is negative for both glucose fermentation and arginine hydrolysis. in addition, ureaplasmas were detected from these animals. ureaplasmas were compared serologically with ureaplasma strains isolated fr ...	1983	6631416
infectivity of isolates of trichinella and the ability of an arctic isolate to survive freezing temperatures in the raccoon, procyon lotor, under experimental conditions.	the objectives of this study were to determine if the raccoon was a useful experimental animal for infections of trichinella and to determine if the ability of trichinella to survive freezing conditions, known to occur in wild animals, could be duplicated under laboratory conditions. the isolates of trichinella used in this study were from pigs, polar bear, wolverine, arctic fox and t. spiralis var. pseudospiralis originally isolated from a raccoon in the ussr. the raccoon was found to be a usef ...	1983	6644931
immediate effects of digit amputation on si cortex in the raccoon: unmasking of inhibitory fields.	immediately after removal of one digit, inhibitory receptive fields were revealed in the affected part of somatosensory cortex. these were usually seen as 'off' responses if only a short, tapping stimulus is used. over the course of several weeks, these inhibitory responses disappear and are replaced by excitatory responses. these changes are seen with both alpha-chloralose and barbiturate anesthesia.	1983	6661627

experimental cerebrospinal nematodiasis due to baylisascaris procyonis in chickens.	avian cerebrospinal nematodiasis was studied in chickens experimentally inoculated with infective eggs of baylisascaris procyonis of raccoon origin. birds each received 3,200, 1,600, 800, 400, 200, or 0 eggs, one dose per group of 10 birds. central nervous system (cns) disease developed in 17 of the 50 infected birds. birds receiving the higher dosages exhibited the worst clinical signs, had higher mortality rates, lived for shorter duration, and had the most severe brain lesions. onset of cns d ...	1983	6682655
topography of neurons of the raccoon main cuneate nucleus with projections to the inferior colliculus.	the origin of the projection from the raccoon main cuneate nucleus to the inferior colliculus has been demonstrated by means of retrograde transport of horseradish peroxidase. neurons of the polymorphic division of the main cuneate nucleus project to the inferior colliculus via the medial lemniscus. neurons projecting to the inferior colliculus are only found caudal to the obex and do not overlap significantly with the distribution of cuneocerebellar neurons as in the cat.	1984	6697178
distribution of metals in tissues of beaver, raccoon and otter from ontario, canada.	mercury and selenium concentrations were positively correlated in liver tissue of beaver, raccoon and otter from an undisturbed watershed in south central ontario. selenium accumulation in piscivorous mammals may represent a protective mechanism against methylmercury toxicity to animals exposed to high mercury levels in their diet. this paper also reports the levels of several other metals in tissues of three wild fur-bearing mammal species.	1984	6710135
raccoon-like periorbital leukoderma from contact with swim goggles.	a 12-year-old girl developed a periorbital leukoderma from contact with swim goggles. she had worn the same goggles the preceding year and re-used them after the leukoderma had cleared without any ill effects. the hypopigmentation was believed to be caused by the leakage of breakdown products in the neoprene rubber or glue. these breakdown products may have caused a toxic rather than an allergic reaction on skin contact, inhibiting melanin production possibly by competitive inhibition of tyrosin ...	1984	6713847
contralateral corticothalamic projections from area 6 in the raccoon.	contralateral corticothalamic projections from cytoarchitectonic area 6 in the raccoon were studied using the autoradiographic tracing technique. following injections of tritiated amino acids, accumulations of silver grains were present over both the ipsilateral and contralateral ventral medial, central lateral, paracentral, central medial, parafascicular and mediodorsal thalamic nuclei. these nuclei are also known to receive a number bilateral subcortical motor inputs. the additional presence o ...	1984	6733457
experimental infection of domestic swine with baylisascaris procyonis from raccoons.	six 8-week-old ascarid-naive pigs which were experimentally infected with 72,000 embryonated baylisascaris procyonis eggs of raccoon origin developed lesions limited to the intestines and liver. intestinal lesions consisted of multifocal areas of inflammation by macrophages, eosinophils, and lymphocytes in the mucosa and submucosa, in association with baylisascaris larvae; similar lesions were seen in the mesenteric lymph nodes. typical white, granulation type, multifocal interstitial hepatitis ...	1984	6742572
