Abstract In the IVITA Marangani FMV-UNMSM, with the aim of producing secretory induction of IgG, toxin of Clostrídium perfringens type A, to reduce mortality due to enterotoxemia in offspring of alpacas. Prepared a toxoid from young alpacas intestine samples with positive enterotoxemia to C. perfringens type a. were analyzed using culture media spreads in anaerobic, microscopic morphology showed bacilli Gram (+) short. Biochemically characterized lecithinase +, hydrolysis, catalase - gelatin +, H2S +, glucose fermentation +, lipase - Índole-, aerobic growth-, urea-, nitrate +, mobility-, esculin - and gas +. Was administered 2 mL of toxoid to mothers pregnant for the ninth and tenth month of gestation and young 2 mL of toxoid 10 days after born divided into 4 groups: 1) vaccinated mother- young, 2) mothers not vaccinate. There were no cases of enterotoxemia mortality, morbidity was: 15%, 15%, 25% and 30% for groups 1, 2, 3, and 4 respectively. The results confirmed that the administration of toxoid prepared from strains of Clostrídium perfringens type A induced greater protection in groups 1 and 2 that in groups 3 and 4. Mass vaccination is suggested to pregnant females and young from the herd of alpacas according to what has been done in Group 1. It is concluded that toxoid induces protection against enterotoxemia.
