Abstract

Coagulase negative Staphylococci (CoNS) are recognized as an important cause of nosocomial infection, especially in neonates and patients with indwelling prosthetic devices. The CoNS resistance rate to oxacillin has been increasing. Therefore, rapid and accurate detection of oxacillin resistance is essential in order to determine the most appropriate antimicrobial therapy. This study aimed to prove that latex agglutination test and oxacillin resistant screening agar base (ORSAB) medium can be used for rapid detection of oxacilllin resistant CoNS (ORCoNS). Latex agglutination test and ORSAB medium compared with the conventional method was conducted in this study toward 30 clinical isolates of CoNS for the detection of ORCoNS. Mc Nemar test was used to analyze the data. The study result revealed that there was no significant difference (P>0.05) in terms of ORCoNS detection between the latex agglutination test and ORSAB medium on the one hand, and the conventional method on the other. It is concluded that latex agglutination test and ORSAB medium can be used for rapid detection of ORCoNS. (Med J Indones 2007; 16:228-32)Keywords: nosocomial infection, rapid detection, mecA gene

Abstract

Coagulase negative staphylococci (CoNS) are the common bacterias causing hospital-acquired infection manifested as bacteremia. The antibiotics therapy against bacterial infection is mostly empiric, whereas the bacterial pattern and its sensitivity to antibiotics differ between region and from year to year. The objective of this study wasto determine the changes of prevalence and antibiotics sensitivity pattern of CoNS, the etiologic agent of bacteremia in patients hospitalised in Dr.Saiful Anwar General Hospital, Malang. Culture and antibiotic sensitivity test wereperformed on 650 and 1063 blood samples during the year of 2000-2001and 2004-2005 respectively in the Laboratory of Microbiology, Faculty of Medicine, Brawijaya University / Dr.Saiful Anwar General Hospital in Malang following NCCLS  1997. ChiSquare test was used to analysed of data. The result of this study revealed that the CoNS was the most isolate found in the blood samples and its resistance to beta lactam antibiotics tends to increase statistically. Key words:Coagulase negative staphylococci, antibiotics sensitivity pattern
