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

Abstract

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.
