Isolation and Identification of a Leptospire of The Hebdomadis Serogroup (L. Hardjo) From Cattle in Canada

A Robertson et al. Can J Comp Med Vet Sci. 1964 Jan.

Abstract

During the summer of 1961 an outbreak of atypical mastitis in a small herd of dairy cattle was investigated. The clinical findings, which included a single abortion, were suggestive of leptospirosis and serological studies indicated that a serotype other than the usual L. pomona was the causative agent. A fastidious leptospire recovered from the urine of one cow has been identified as L. hardjo, a member of the hebdomadis group. The difficulties encountered in isolation, adaptation to standard media and serotyping are described.
