Intramammary infusion of a live culture of Lactococcus lactis in ewes to treat staphylococcal mastitis

Abstract

Under our experimental conditions, the L. lactis treatment led to a transient clearance of the pathogen in the gland, but also caused mild to moderate clinical cases of mastitis. We believe it is still early to implement bacterial formulations as alternatives in treating mastitis in ruminants and further experimentation is needed.
