چکیده
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 were analyzed for botulinum neurotoxins (BoNTs) and C. botulinum spores. C. botulinum types C and D antibodies were significantly (p < 0.05) increased in vaccinated animals. Vaccination with botulism vaccine significantly reduced (p < 0.001) BoNTs and C. botulinum spores in cattle feces. Our findings represent that C. botulinum vaccination increases specific blood serum antibodies and reduces free BoNTs and C. botulinum spores in feces.

Immunogenic and Protective Potentials of Recombinant Receptor Binding Domain and a C-Terminal Fragment of Clostridium botulinum Neurotoxin Type E
Clostridium Botulinum Type E neurotoxin heavy chain consists of two domains: the translocation domain asthe N-terminal half and the binding domain as the Cterminal half (Hc). One effective way to neutralize botulinum neurotoxin is to inhibit binding of this toxin to neuromuscular synapses with antibodies against binding domain. Two synthetic genes, coding for Hc (the full length binding d...

In USA, the potency of commercial vaccines containing Clostridium botulinum type C toxoid is determined by a mink vaccination-challenge assay outlined in the Code of Federal Regulations, Title 9, Part 113.110. A more humane potency test is desired, and this study provides preliminary data in support of a serological assay that correlates post-vaccination antitoxin titers of guinea pigs to vacci...

The aim of this study is to investigate Clostridium botulinum at a Saxony dairy farm with 159 cows and 18 heifers. The animals exhibited clinical symptoms of chronic botulism. To determine the source of the infection, feces, blood, organs, and gastrointestinal fluids of dead or euthanized cows; as well as soil, water, silage and manure were tested for C. botulinum spores and BoNTs using ELISA. ...
