Abstract

The present study was designed to determine the slime production of coagulase-negative staphylococci (CoNS) and the enterotoxigenic properties of strains, and to evaluate the clinical importance of slime-producing CoNS and enterotoxigenic strains isolated from various human clinical specimens. For this purpose, a total of 120 strains were isolated and identified, and further characterized for their slime production and enterotoxigenicity. Of the clinical isolates, 55 (45.8 %) were found to be , and the others (54.2 %) were identified as CoNS. Of the CoNS, 20 (16.7 %) were further identified as , 18 (15 %) as , six (5 %) as , six (5 %) as , five (4.2 %) as , four (3.3 %) as , and two each (1.7 %) as , and , respectively. Thirty-nine (60 %) of 65 CoNS were found to be slime producers. Slime production was observed in all CoNS, except , mostly from blood (38.5 %), tracheal aspiration (20.5 %) and urine (12.8 %) specimens. In addition, of the 55 isolates, 46 (83.6 %) were found to be enterotoxigenic, and of these strains, 39 (84.7 %) were positive for staphylococcal enterotoxin (SE)A. The results of this study showed that the slime-producing CoNS were mostly found in clinical specimens of blood, tracheal aspirate and urine. SEA was the predominant enterotoxin type detected in strains from human clinical specimens.
