The efficacy of Lamstreptocide A & B was studied on 9 natural cases of bovine and caprine dermatophilosis in 8 different farms in St. Kitts, employing standard histopathologic and bacteriological methods. The lesions of 5 of the treated cases were dried-up, and there was marked peeling-off of scabs of a severely affected case exposing erythematous underlying tissue, at 3 weeks post-application of the product. Apart from 3 mild cases which were not available for follow-up studies and which were reported to have recovered, there was no outright recovery of the 5 animals after treatment at 3 weeks, and even after a second application of the product. An in vitro sensitivity test of the product revealed a slowing down of growth of Dermatophilus congolensis at concentrations in excess of 1 % by agar-streak method. However, there was no inhibition of growth of the bacterium by an agar-impregnated sensitivity method.
