Key Points

To characterize the molecular and epidemiological aspects of Streptococcus uberis infections in a dairy herd.
Longitudinal study conducted on a large commercial dairy herd in South Africa.
Samples of milk collected for molecular analysis of Streptococcus uberis strains.
Intra-mammary infections were found to be transient, with indications of environmental origins rather than persistent infections.

Abstract

IMI in this herd was transient, possibly of environmental origin rather than persistent udder infections, making a point-source of infection less likely.
