ABSTRACT
Nosocomial infection is one cause of increased morbidity and mortality in hospitals.
ICU-acquired infection rates are higher than hospital-acquired infection rates in
general ward patients. MRSA is a major pathogen that cause nosocomial infection in
ICU. This research was descriptive method using crosssectional approach to know
percentage and resistant patterns of MRSA in ICU of Arifin Achmad General
Hospital of Riau. The total of 57 samples obtained from blood, sputum, and urine. All
isolates of S.aureus were tested for the presence of a MRSA using cefoxitin disc
diffusion test. Resistant test of MRSA isolates were performed according to disc
diffusion method againts sixteen antibiotics. MRSA percentage from 44 isolates were
11,3%. All of MRSA isolates were resistant to betalactam antibiotics, including
ampicillin, amoxicillin-clavulanic acid, cefotaxime, ceftriaxone and meropenem. No
MRSA isolates were resistant to vancomycin, linezolid, chloramphenicol and
trimethoprim-sulfametoxazole.
