106 BACTERIOSES1% alum dips. In chronic cases, an intramuscular injection of 70 mg of streptomycinand 70,000 units of penicillin may be administered two months before shearing.This drug therapy seems to be very effective and prevents difficulties in shearing.The use of antibiotics (streptomycin, penicillin, and others) was effective in producingclinical cure or improvement in affected animals, but did not always eliminatethe causal agent.The infection is controlled by isolating or eliminating chronically sick animalsand combating ectoparasites. Externally applied insecticides are used to combat bitinginsects.The study of a vaccine against animal dermatophilosis is in an experimental stage(Sutherland and Robertson, 1988; How et al., 1990).BibliographyAinsworth, G.C., P.K.C.
