experimental rabies in skunks: mechanisms of infection of the salivary glands.striped skunks (mephitis mephitis) were inoculated into the right submandibular salivary gland with street rabies virus. they were killed at various times after inoculation and several tissues were examined by immunofluorescence and light microscopy. right and left superior cervical, nodose and trigeminal ganglia, medulla oblongata and at least three regions of right and left submandibular salivary glands were examined by the fluorescent antibody technique. intracerebral titrations of salivary g ...19836357414
experimental rabies in skunks: effects of immunosuppression induced by cyclophosphamide.striped skunks (mephitis mephitis) were inoculated with street rabies virus and immunosuppressed with several doses of cyclophosphamide. control skunks were inoculated with street virus only. the skunks were killed in terminal stages of the disease and several tissues were collected for examination by immunofluorescence, light microscopy and viral titration. sera collected at euthanasia from most of the principals did not contain detectable rabies neutralizing antibodies, whereas high titers occ ...19846370390
rabies: spongiform lesions in the brain.striped skunks (mephitis mephitis) experimentally infected with street rabies virus developed spongiform lesions that light- and electron-microscopically were indistinguishable from those found in the transmissible spongiform encephalopathies of man and animals. these previously unreported lesions were also detected in naturally occurring cases of rabies. the spongiform lesions consisted of round or oval vacuoles in the neuropil, rarely in neuronal perikarya. the most severely affected areas wer ...19846464676
rabies virus in the salivary glands and nasal mucosa of naturally infected skunks.several salivary glands and the nasal mucosa of rabid skunks (mephitis mephitis) contained rabies virus. generally titers were high in the submandibular, moderate in the parotid and low to moderate in the zygomatic, molar and sublingual salivary glands. the nasal mucosa (glands and epithelium) contained virus at low to moderate titers that occasionally were equal to titers in brain.19846478304
presence of neutralizing antibodies to rabies virus in striped skunks from areas free of skunk rabies in alberta.nine percent of 198 serum samples from striped skunks, mephitis mephitis (schreber) from five areas of alberta were positive for rabies neutralizing antibody. positive samples were minimal (2%) from specimens sampled in an area enzootic for rabies and occurred at greater rates in areas negative for skunk rabies. transmission of rabies virus to skunks may have been from a source other than skunks in those areas, most probably from bats.19846492318
rotavirus-associated diarrhea in young raccoons (procyon lotor), striped skunks (mephitis mephitis) and red foxes (vulpes vulpes).electron microscopy and a commercial elisa test for rotavirus antigen were used to diagnose rotavirus infection in diarrheic raccoons (procyon lotor), striped skunks (mephitis mephitis) and red foxes (vulpes vulpes). gross and histopathological changes in two raccoons and two red foxes were found to be very similar to those described previously in rotavirus mediated diarrhea in other animals. while an etiology for the diarrhea is not definitively established, it would appear to involve rotavirus ...19846330385
seasonal occurrence and habitat preference of rabid skunks in southern alberta.eighty cases of rabies in skunks (mephitis mephitis) occurred in southern alberta between december 1, 1979 and december 31, 1981. fifty-three percent (43-80) were diagnosed during march-may (breeding and parturition). there were significantly more rabid females than males during that period. nonrabid and rabid skunks appeared to select occupied sites rather than unoccupied sites for winter and maternity denning.198417422376

rabies and rabies control in striped skunks (mephitis mephitis) in three prairie regions of western north america.the number and geographic distribution of rabies cases in striped skunks (mephitis mephitis) from saskatchewan (n = 2,506 cases), montana (n = 1,142), and alberta (n = 199) since 1963 were reviewed. in saskatchewan the number of cases increased steadily for 5 yr and then fluctuated consistently in a 4 yr cyclic pattern. similarly an initial sweep across the province was followed by a cyclic pattern of geographic expansion (3 to 4 yr) and reduction (1 to 2 yr). no organized control efforts were c ...19883045346
predation pressure on an imperfect batesian micicry complex in the presence of alternative prey.differential predation pressure and the probability of predation on a batesian mimicry complex and on alternative prey were estimatedin a field experiment. the mimicry complex was composed of a noxious model (eleodes obscura (say)) and a palatable mimic (stenomorpha marginata (leconte)). house crickets (acheta domesticus) (linn.) were used as alternative prey. the experiment was conducted for 23 nights in august and september to approximate the peak seasonal activity time period during which bot ...198828312410
trichinella spiralis in an agricultural ecosystem. iii. epidemiological investigations of trichinella spiralis in resident wild and feral animals.as part of a larger epidemiological study examining the transmission of trichinella spiralis in an agricultural ecosystem, resident wild and feral animals were trapped to determine the extent of their involvement in the natural, on-farm cycling of the parasite among swine. during a 21-mo-study, seven of 15 skunks (mephitis mephitis), one of three opossums (didelphis virginiana), two of two feral domestic cats and a raccoon (procyon lotor) were found to be infected, while five shrews (blarina bre ...19883193554
comparison of spongiform lesions in experimental scrapie and rabies in skunks.striped skunks were inoculated intracerebrally with the scrapie agent (suspension of brain from a naturally infected suffolk sheep) or intramuscularly with street rabies virus (suspension of salivary glands from naturally infected skunks). those given the scrapie agent developed clinical signs of weakness, posterior ataxia, and emaciation after incubated periods of 8 to 23 months. those inoculated with rabies virus developed clinical signs of rabies (aggressive behavior, hyperexcitability, ataxi ...19883213430
oral administration of an attenuated strain of canine adenovirus (type 2) to raccoons, foxes, skunk, and mongoose.an attenuated strain of canine adenovirus type-2 (cav-2) was administered orally to 2 foxes (vulpes fulva), 6 raccoons (procyon lotor), a skunk (mephitis mephitis), and a mongoose (herpestus auropunctatus). blood was collected weekly from the animals to monitor cav-2 virus-neutralizing antibody titers. all animals had increases in titers. sera from 8 foxes, 30 mongooses, 52 raccoons, and 22 skunks trapped in the field had naturally occurring antibody to cav-2.19883348527
growth characteristics in cell culture and pathogenicity in mice of two terrestrial rabies strains indigenous to canada.two strains of street rabies virus from striped skunks (mephitis mephitis) were used to infect either a murine neuroblastoma (na 1300) or a baby hamster kidney (bhk-21/c13) cell culture and the cell infection rates were noted during 4 days postinfection. these cultures were then passaged for four consecutive passages, and the viruses obtained in the supernatant fluids of passage 4 were then treated as original isolates and used to infect both neuroblastoma and baby hamster kidney cells. the mort ...19883378201
sarcocystis sp. in mountain goats (oreamnos americanus) in washington: prevalence and search for the definitive host.during october and november 1986, sarcocystis sp. was detected in 24 of 56 (43%) tongues from hunter-killed mountain goats (oreamnos americanus) in washington (usa). sarcocysts had an unusual sessile polyp-shaped branched wall. mean size of 154 sarcocysts was 71.3 x 37.8 microns (range, 20 to 248 x 10 to 120 microns), and the mean intensity was 2.3 (range, 1 to 28). in an attempt to identify the definitive host, infected tongues were fed to four coyotes (canis latrans), eight domestic dogs, four ...19892509738
persistent infections of a field strain of rabies virus in murine neuroblastoma (na-c1300) cell cultures.rabies virus from the brain of a striped skunk (mephitis mephitis) from ontario was inoculated into murine neuroblastoma (na-c1300) cell cultures. these cultures were incubated and the cells were subcultured every three to four days. the presence of viral antigen in the cell cultures was monitored by direct immunofluorescent staining and in the culture fluids by titration in either baby hamster kidney (bhk/c13) or na cells or in experimental mice. the virus-infected na cultures evolved from an i ...19892590871
host associations of ticks (acari: ixodidae) parasitizing medium-sized mammals in a lyme disease endemic area of southern new york.ticks of eight medium-sized mammal species were studied in an area of endemic lyme disease in westchester county, n.y., from 1 april 1984 to 31 march 1985. most (81%) of the 266 total mammal captures were raccoon, procyon lotor (l.) (47%), opossum, didelphis virginiana (kerr) (19%), and striped skunk, mephitis mephitis schreber (15%); these host species accounted for 91% of the 1,519 ticks collected. although the total number of ticks was rather evenly distributed among these mammals, species co ...19892724317
ineffectiveness and comparative pathogenicity of attenuated rabies virus vaccines for the striped skunk (mephitis mephitis).three attenuated rabies virus vaccines (sad-b19, era/bhk-21, aza 2) were compared for efficacy and safety in the striped skunk (mephitis mephitis) by the oral and intranasal routes. the sad-b19 and era/bhk-21 vaccines were given orally; all three vaccines were given intranasally. oral administration of sad-b19 and era/bhk-21 vaccines induced neither seroconversion nor significant protection against rabies challenge. one skunk which consumed a sad-b19 vaccine-laden bait succumbed to vaccine-induc ...19902304207
intramuscular vaccination of skunks and raccoons against rabies.live-captured striped skunks (mephitis mephitis) and raccoons (procyon lotor) were immunized with inactivated rabies vaccine by intramuscular injection and released at the point of capture during a rabies control program in metropolitan toronto (ontario, canada). serum samples collected prior to and following vaccination revealed that 100% of the skunks and 98% of the raccoons seroconverted. rabies antibody was still detectable 314 to 757 days postvaccination. five of six skunks vaccinated in th ...19902338727
the role of medium-sized mammals as reservoirs of borrelia burgdorferi in southern new york.the ability of raccoons (procyon lotor), striped skunks (mephitis mephitis) and opossums (didelphis virginiana) to serve as reservoirs of borrelia burgdorferi, the spirochetal agent of lyme disease, was compared with that of white-footed mice (peromyscus leucopus). twenty-eight (28) medium-sized mammals and 34 white-footed mice were captured in westchester county, new york (usa) in summer 1986. animals were caged over pans of water for 1 to 2 days to recover engorged tick larvae (ixodes dammini) ...19902388356
wild carnivore acceptance of baits for delivery of liquid rabies vaccine.a series of experiments are described on the acceptance, by red foxes (vulpes vulpes) and other species, of two types of vaccine-baits intended to deliver liquid rabies vaccine. the baits consisted of a cube of sponge coated in a mixture of tallow and wax, or a plastic blister-pack embedded in tallow. all baits contained tetracycline as a biological marking agent: examination of thin sections of carnivore canines under an ultraviolet microscope revealed a fluorescent line of tetracycline if an i ...19902250325
