This finding was in good agreement with the observations of Younger et al (5), who demonstrated multi drug resistance in 45 per cent of coagulase negative staphylococcal isolates from patients with ventriculo-peritoneal shunt infections.
Identification of the coagulase types of this species has helped in epidemiological investigations of food poisoning (Shimizu et al., 2000) and has contributed significantly to the understanding of the sources, transmission, and spread of food poisoning.
The increasing use of broad spectrum antibiotics is resulting in emergence of resistance in coagulase negative staphylococci (CoNS) as well4.
Four to five typical and atypical Staphylococcus colonies were isolated and tested by Gram staining, catalase test, glucose oxidation and fermentation, mannitol fermentation, thermonuclease production and coagulase test (MACFADDIN, 2000; SILVA et al., 2007).
The organism was catalase positive with negative coagulase reaction (slide as well as tube coagulase) and showed haemolysis on blood agar.
