High Prevalence of Multidrug-Resistance MRSA and VRSA of Different Infections from AI-Jumhuory Teaching Hospital Patients in Mosul

Staphylococcus aureus is major human pathogen causing large variety of infections worldwide. This study carried out to isolate S. aureus from different clinical cases, also detection of MRSA prevalence and VRSA emergence, in addition to shedding light on strains that have to be multidrug resistance against various antibiotics. The clinical samples were collected from Al-Jumhuory Teaching Hospital patients in Mosul, isolates identification were achieved by conventional procedures including biochemical and physiological tests, and the specific latex agglutination test. The sensitivity pattern achieved by using disk diffusion technique, for MRSA and VRSA detection oxacillin-disk (1 μg) and vancomycin-disk (30 μg) were used respectively. Results revealed, among 17 S. aureus isolates, 7 (41%) were mostly isolated from patients with wound and burn infections. Isolates had high resistance rate against ampicillin (100%) and cefotaxime (81%), and lower resistance rate against several antibiotics. MRSA was 88% of total isolates, 93.3% of MRSA were multidrug resistance to 3-9 of antibiotics. Six isolates (40%) of MRSA were VRSA. It is concluded that antibiotics other than vancomycin can be used as anti-MRSA agents after a sensitivity test to prevent the prevalence of VRSA, the major cause of this chemotherapy problems maybe irrational and indiscriminate use of broad-spectrum antibiotics.
