Virus content of Shope papillomas of cottontail rabbits.
The virus content of naturally occurring and experimentally induced papillomas of cottontail rabbits varies considerably. As a rule different individual papillomas on the same rabbit were found to have a similar virus content. The amount of virus usually increased as the tumors aged from 6 to 12 weeks. After 12 weeks there was no consistent pattern of change in virus con tent of papillomas, and...
متن کاملEnzootic transmission of Anaplasma bovis in Nantucket cottontail rabbits.
Serological studies of cottontail rabbits sampled from Nantucket Island, Mass., have suggested exposure to at least two ehrlichiae. The agent of human granulocytic ehrlichiosis (Anaplasma phagocytophilum) is intensely enzootic in rabbits there, but the identity of the other ehrlichial infection remains undescribed. We sampled rabbits over five transmission seasons and tested their blood and tis...
متن کاملOccurrence of Escherichia coli in Wild Cottontail Rabbits.
Free-ranging cottontail rabbits (Sylvilagus floridanus) from two areas in central Pennsylvania were sampled over a 4-year period. Large numbers of coliforms were isolated from the intestinal tracts of these animals; in 136 of the 141 rabbits sampled, Escherichia coli was found to be a major component of the alimentary flora. Four serogroups (O7, O77, O73, and O103) were predominant among the is...
متن کاملSerologic analyses of cottontail rabbits for antibodies to Borrelia burgdorferi.
An enzyme-linked immunosorbent assay was developed to detect antibodies to Borrelia burgdorferi in cottontail rabbits captured in Millbrook, N.Y., and New York, N.Y. Five antigenically variable strains of B. burgdorferi were analyzed to determine the variability of serologic test results. In analyses of 79 serum samples, seropositivity ranged from 56% for a strain cultured from kidney tissues o...
متن کاملA Hemolytic System Associated with Enteritis in Rabbits
A disease characterized by frequent association of enteritis and polyagglutinable cells often develops in weanling rabbits. The red cell lesion renders the cells susceptible to agglutination and hemolysis in normal rabbit sera. The degree of red cell abnormality varies among different animals and disappears when the animals recover. The abnormality of the red cells responsible for their polyagg...
