Comparison of Antibiotic Resistance Pattern of Coagulase Positive and Coagulase Negative Staphylococcus aureus Isolates from Indian Sweets

Out of 100 samples of sweets collected 80 samples showed the presence of S. aureus. Among them 61 (76%) isolates were positive for coagulase and 19 (24%) isolates were negative for the same. Incidences of S. aureus was more in Laddu (88%) and least (69%) in Mysore Pak and Gulab Jamun. Among coagulase positive isolates, isolates VO4M and GS10MP were least potent showing resistant to zero antibiotics and isolates PR7MP and SK4DP were more potent being resistant to 12 antibiotics. Whereas, among coagulase negative isolates, isolate GO1P was least potent showing resistant to zero antibiotics and isolate SO3M was more potent showing resistant to 14 antibiotics. Streptomycin and Gentamycin were found to be effective drugs and Oxacillin and Amikacin were found to be least effective drugs against coagulase positive isolates. Gentamycin, Chloramphenicol, Clindamycin, Erythromycin and Streptomycin were found to be effective drugs and Penicillin and Ampicillin were found to be least effective drugs against coagulase negative isolates.
