Abstract

1. An outbreak of skin lesions caused by pathogenic staphyloco
cci on a herd of sheep (local) breed (Rahmani) was described. 2. The outbreak was first clinically mis-diagnosed as Pox or
Contageous pustuler dermatitis but after considering clinical differential diagnosis and after carrying out bacteriolgical inves tigation the epidemic proved to be recurrent skin lesions caused by staphylococci, & 19 pathogenic strains of Satap < /em>hylococcus aureus were isolated from the lesions and milk of affected
animals. 3. Most of the known antibitotics formerly used caused tem
porary improvement and relapses always occurred. 4. Some factors concerning the farm, the flock and the organism
played a role in the spread of infection. 5. Some immunological considerations were illustrated as regard
staphylococcal infection. 6. Staphylococcl infection and its zoonotic role was referred to.
