Previous studies have shown that the clove essential oil concentration of 200 mg/kg did not present toxicity and histopathological changes in the liver. Based on the evidence presented in this study, we decided to evaluate in vivo the ability of a previously developed fermented dairy beverage, tested only in vitro, in which the standard chemical preservative, potassium sorbate, was replaced by clove essential ...

The diseases caused for Clostridium perfringens are generically called enterotoxemias because toxins produced in the intestine may be absorbed into the general circulation. C. perfringens type B, grown in batch fermentation, produced toxins used to obtain veterinary vaccines. Glucose in concentrations of 1.4–111.1 mM was used to define the culture medium. The minimum concentration for a satisfactory production ...
Conselho Nacional de Desenvolvimento Científico e Tecnológico; Clostridium perfringens tipo B, bactéria anaeróbia, heterofermentativa, gram-positiva e produtora de toxina, é importante agente causador de doenças entéricas em animais. As toxinas inativadas α, β e ε produzidas por esse microrganismo estão presentes na composição das vacinas veterinárias contra clostridioses. Neste trabalho, estudou-se o efeito da...
