The antibody response of cattle to Clostridium botulinum types C and D toxoids.
The resistance of cattle with varying serum-antitoxin titres was determined by per os challenge. The results proved that a solid immunity can be produced against C. botulinum toxins C1 and D. The immune response of cattle to various quantities of C. botulinum C1 and D toxoids, aluminium-phosphate-adsorbed and in water-in-oil emulsion was investigated. The response to antigen in water-in-oil emu...
متن کاملEfficacy of Clostridium botulinum types C and D toxoid vaccination in Danish cows.
In the present study the efficacy Botulism vaccine (formalinised aluminum hydroxide gel adsorbed toxoid of Clostridium botulinum types C and D) was evaluated in four Danish dairy cows under field conditions. Other four dairy herds were unvaccinated. Blood serum of all animals was analyzed for specific C. botulinum types A, B, C, D and E antibodies using a developed ELISA. Feces of all animals w...
متن کاملThe toxic antigenic factors produced by Clostridium botulinum types C and D.
JANSEN, B. C. The toxic antigenic factors produced by Clostridium botulinum types C and D. Onderstepoort ]. vet Res., 38 (2), 93-98 (1971). The toxic factors produced by Clostridium botulinum (Van Ermengem, 1896), types C and D were determined. Monospecific antisera were prepared against the different factors. It was shown that type Coc produces factors C" C2 and D; type C f3 produces factor C ...
متن کاملProduction and Evaluation of a Recombinant Chimeric Vaccine against Clostridium botulinum Neurotoxin Types C and D
Bovine botulism is a fatal disease that is caused by botulinum neurotoxins (BoNTs) produced by Clostridium botulinum serotypes C and D and that causes great economic losses, with nearly 100% lethality during outbreaks. It has also been considered a potential source of human food-borne illness in many countries. Vaccination has been reported to be the most effective way to control bovine botulis...
متن کاملUse of ganglioside affinity filters to identify toxigenic strains of Clostridium botulinum types C and D.
Clostridium botulinum neurotoxin is synthesized by toxic clones grown anaerobically on ganglioside affinity filters. The toxin binds to the filters and is detected by reaction with 125I-immunoglobulin G from type-specific antitoxin. Toxin spots from culture filtrates were similarly identified. The C. botulinum type C and D strains were selected for developing this affinity filter assay because ...
