Complement fixing and agglutinating antibody responses and leptospiruria in calves inoculated with Leptospira serotypes pomona, hardjo, copenhageni or ballum

Abstract

Extract

Infection of cattle with various serotypes of Leptospira may result in a variety of clinical signs, including haemoglobinuria, abortions, stillbirths or atypical mastitis. In many instances, however, a mild infection occurs in which clinical signs are not observed. In these cases diagnosis is based on serological evidence.
