1. In vitro experiments carried out by a modified Rideal-Walker technique showed the superiority of CTAB over chlorine and chloroxylenol disinfectants against Str. agalactiae.

2. The disinfectant action of 1 % CTAB persisted on the surface of dry hands and cows' teats for a period of at least 3 hr. Subsequent moistening of the hands with milk reduced the efficiency of this disinfectant.

3. For the prevention of dissemination of Str. agalactiae by means of milkers' hands and at the same time to reduce the incidence of infection on the surface of teats, a lanette wax-oil base containing 1 % CTAB was tested. It was found that the inclusion in the cream base of CTAB did not reduce its bactericidal efficiency.
