Resistance of staphylococcus aureus isolated from nasal of hospital staff and patients against antibiotics

الملخص EN

The aim of this investigation was to determine the incidence of Staphylococcus aureus in the nasal cavity and theirs antibiotic sensitivity profiles in health care workers and fallowed patients in Mosul Hospitals, Iraq.

Nasal samples were inoculated on primary isolation medium and isolated S.

aureus strains were identified using specific conventional bacteriological tests.

Antimicrobial susceptibility profiles against some antibiotics were determined .The results explained that 34(34%) represented nasal bearing of S.

aureus, and among them, 15 (44.11%) were MRSA holders.

42 (42%) were nasal carriers of Staphylococcus and among them 12 (28.28%) were MRSA carriers.

Highest rate of MRSA nasal carriage 33.3 % ( 5/15) was found among nurses and at lower percentage among laboratory personal 4 (26.6%) , doctors and cleanness workers accounted for 20 % (2/15) of MRSA carriers for each.

The results showed that S.

aureus strains from nasal cavity of HCW were sensitive to Co-trimoxazole, Amikacin ,Gentamycin, Clindamycin at 97%,88.23%,85.29,79.4% and toward ciprofloxacin and cefoxitin at 82.35 for each one.
