Abstract

Out of 132 strains of Stapllylococci isolated during bacteriological survey or catering establishments, 43 (32.57%) were coagulase positive, which were evaluated for TNase activity, enterotoxigenicity, antibiotic sensitivity, phage typing, lysostaphin sensitivity, mannitol fermentation and phosphatase reaction. Thirty seven isolates (86.04 %) were positive for TNase activity; 18 out of the 40 coagulase positive isolates (45.00%) elaborated enterotoxin types A-E and AB, predominantly A type. Lysostaphin sensitivity and phosphatase reactions were 88.8 and 94.4 % respectively among enterotoxigenic types. Majority of the typable isolates showed iii and IV group phage reactions which are known to include enterotoxigenic types. Antibiotic sensitivity showed 92.67~~ resistance towards penicillin among the coagulase positive types and 98.87 and 17.97% resistance towards penicillin and lincomycin respectively among coagulase negative types. This observation clearly points to the indiscriminate use of antibiotics leading to the prevalence or drug resistant Staphylococci in catering establisbments.
