Humoral responses in cattle to commercial vaccines containing Clostridium perfringens epsilon toxoid and C. botulinum types C and D toxoids last less than a-year.

The aim of this study was to evaluate the titers of neutralizing antibodies in cattle inoculated with multivalent commercial clostridial vaccines containing C. botulinum type C (BoNTC), C. botulinum type D (BoNTD), and C.

Comparison of humoral neutralizing antibody response in rabbits, guinea pigs, and cattle vaccinated with epsilon and beta toxoids from Clostridium perfringens and C. botulinum types C and D toxoids.

Rabbits and guinea pigs are used in the official control and validation of clostridial vaccines, but it is unknown whether the antitoxin titers obtained in these animals corroborate with the humoral response in bovine. The objective of the study was to compare the humoral antibody response of guinea pig and rabbits to those obtained in cattle vaccinated with a commercial vaccine containing Clostridium perfringens epsilon and beta, and Clostridium botulinum types C and D toxoids. This study revealed the same level of humoral response in rabbits and cattle for all four toxoids tested, including C.

Detection of toxins A/B and isolation of Clostridium difficile and Clostridium perfringens from dogs in Minas Gerais, Brazil.

The objective of this study was to detect C. difficile A/B toxins and to isolate strains of C. perfringens and C.
