Background
and Aim: The increases in the prevalence of methicillin-resistant Staphylococcus
aureus (MRSA) from outside healthcare settings are recently reported. This
study was performed to determine the prevalence of community-acquired MRSA and
antibiotic resistance of the isolates from nose of military training soldiers
in Kerman city- 2012.
Materials
and Methods: Nasal samples were collected from 567
training soldiers. S. aureus was identified using standard Methods. MRSA
phenotype was screened by oxacillin and cefoxitin disc. The MRSA was
genetically confirmed by detection of mecA gene by PCR methods.
Antibiotic susceptibility to six antibacterial agents was determined by
standard agar disc diffusion method. Induction of resistance to
clindamycin was performed using the
D-test.
Results:
samples
were isolated from the nose of 39.8% of training soldiers. By the methods used
7.6% of the isolates were identified as MRSA all of them harbored mecA
gene and were sensitive to vancomycin. The highest rate of resistance was
detected against erythromycin (23.3%). Resistance to, clindamycin, gentamicin,
trimethoprime sulfamethoxazole and ciprofloxacin were 14%, 16.3%, 14% and 9.3%
respectively. Induced of Clindamycin resistance among MRSA isolates was not
observed.
Conclusions:
The
high frequency of isolation of S aureus from nose in military
population studied is remarkable. The prevalence of MRSA in this group was %7.8.Although resistance to
other antibacterial agents was not high in these isolates, but due to the
increasing importance of community acquired MRSA frequent surveillance of this
and similar type of population are required in intervals, and physicians should
be informed about the presence of these bacteria to choose appropriate drug for
therapy.
