Objetivo. Evaluar la eficacia terapéutica del fármaco proteolítico “quimotripsina”, en tratamientos conjuntos con un antibiótico betalactámico en vacas con mastitis aguda. Material y métodos. Se evaluaron el conteo de células somáticas (CCS) y los hallazgos semiológicos, comparando la eficacia con un grupo de animales en donde sólo fue utilizado el antibiótico. Resultados. Los resultados revelaron eficacia clínica (disminución del CCS, p<0.01) y ausencia de signos clínicos agudos en el 84.7% de los cuartos observados, incluso observándose respuesta anti-inflamatoria desde las primeras horas del tratamiento. El restante 15.3% también presentó eficacia clínica a la terapia aunque la respuesta fue moderada en comparación con el 84.7% de los casos que tuvieron la respuesta acelerada. Conclusiones. Lo anterior permite concluir que el uso de quimotripsina en casos de mastitis aguda, acelera la respuesta en la glándula mamaria infectada e inflamada, con mayor eficacia que los tratamientos con sólo amoxicilina + ácido clavulánico.

Objective. To evaluate the therapeutic efficacy of a proteolytic drug “chymotrypsin” combined with beta-lactam antibiotics in cows with acute mastitis. Material and Methods. Fourteen cows with acute mastitis. Three cows were treated with a beta-latam antibiotic (BLA) and the other eleven cows were treated with chymotrypsin plus beta-lactam antibiotic (C+BLA). The response was evaluated according to the semiological findings, somatic cell count (SCC) and a microbiological culture. Results. There was a therapeutic efficacy comparing the pre and post treatment period (SCC reduction, p<0.01) and a reduction of clinical signs in 84.7% of treated quarters in the first day of treatment (C+BLA) compared with (BLA). Conclusions. Chymotrypsin improves the treatment of acute mastitis when is combined with BLA, controlling the infected mammary glands, compared with the group treated only with amoxicilina and clavulanic acid.
