Serological response to a booster foot-and-mouth disease vaccination with strains different from the primary vaccine.
revaccination. At one and two months after revaccination there was no significant difference between the responses to revaccination with vaccine identical to the primary vaccine or with the foreign FMD vaccine. It ...
Simultaneous vaccination of piglets against foot-and-mouth disease and classical swine fever.
swine fever (CSF) with a live attenuated vaccine or against both diseases simultaneously at two different sites. The antibody response to the FMD vaccine was not significantly influenced by the ...
Effect of disinfection of drinking water with ozone or chlorine dioxide on survival of Cryptosporidium parvum oocysts.
infection level of 1,000 oocysts (0.1-ml inoculum) per mouse was necessary to induce 100% infection. Treatment of water containing 10(4) oocysts per ml with 1.11 mg of ozone per liter (concentration at time ...
Experimental transmission of enzootic bovine leukosis to cattle, sheep and goats: infectious doses of blood and incubation period of the disease.
A given inoculum can be infectious in sheep and, at the same time, harmless in cattle. The incubation periods, apparently shorter in sheep, were generally in the range from 2 to 5 weeks for the three ...
Spontaneous lesions in the sternums of growing rats.
lesions involving both cartilage and bone elements. Degeneration or aseptic necrosis of the intersternebral cartilage was a frequent finding in most rats that were examined either at 130 or 180 days of age. ...
Naturally-occurring Tyzzer's disease (Bacillus piliformis infection) in commercial rabbits: a clinical and pathological study.
necrosis, patches of mucosal necrosis in ileum, caecum and colon and marked caecal oedema were most prominent at autopsy. In histological sections of the liver, bundles of slightly Gram-negative and Giemsa-, ...
Pathogenic properties of Escherichia coli strains isolated from diarrheic commercial rabbits.
O109:K-: H2, whereas strains from diarrheic weaned rabbits belonged to at least eight different serogroups. It is suggested that two different mechanisms of E. coli enteropathy might exist in rabbits. Health ...
Efficacy of narasin against hepatic and intestinal coccidiosis in rabbits.
was achieved with feed levels from 12 to 24 p.p.m.; there was no influence on oocyst sporulation. Optimal weight gain and food consumption were obtained with levels between 8 and 12 p.p.m.; at higher ...
Field trial with the coccidiostatics metichlorpindol and robenidine in a rabbit farm.
comparison with non medicated rabbits weight gain was 3.46% better. Feed conversion was improved by 6.76 and 6.55% at 33 and 66 ppm levels respectively, while the production index was improved by 19% and 22% ...
The Enrichment of Histomonas meleagridis and Its Pathogen-Specific Protein Analysis: A First Step to Shed Light on Its Virulence.
this protozoon open possibilities to proper treatment. Axenization of H. meleagridis in vitro cultures cocultured with bacteria has been unsuccessful. Numerous unsuccessful attempts at culturing H. ...
