The control of Streptococcus agalactiae mastitis by milking-shed hygiene, with particular reference to hibitane: A preliminary report

Abstract

Extract

Since the advent of antibiotics, in particular penicillin, a great deal of experimental and field work on the control of Streptococcus agalactiae mastitis by these agents has been reported. The fact remains, however, that the incidence of mastitis seems as high as ever despite the marked advance in the treatment of clinical cases. This has led to the somewhat paradoxical situation where, on some dairy farms, more money is now being spent on penicillin than used to be lost through having to cull for mastitis or through the loss of quarters following infection.
