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

Abstract

Infeksi mikobakteria termasuk diantara infeksi yang paling sulit disembuhkan dari semua jenis infeksi bakteri. Mikobakteria yang patogen utamanya adalah Mycobacterium tuberculosis sebagai penyebab tuberkulosis (TB), yang mengakibatkan lebih banyak kematian daripada agen mikroba tunggal lainnya di seluruh dunia. Penelitian ini menggunakan Mycobacterium sp. yang bermanifestasi klinis tuberkulosis atau mirip tuberkulosis. Salah satu usaha untuk mengobati penyakit infeksi akibat Myco­bacterium sp. yang bermanifestasi klinis penyakit tuberkulosis atau mirip tuberkulosis adalah dengan menggunakan isoniazid. Terapi tunggal dengan isoniazid dan kegagalan penggunaan isoniazid ditambah obat lain yang sesuai telah mengakibatkan prevalensi resistensi isoniazid sebesar 10-20% dalam uji klinis di Karibia dan Asia Tenggara. Penelitian ini bertujuan untuk mengetahui apakah bakteri Mycobac­terium sp. yang berasal dari pasien RSSA Malang sudah resisten terhadap isoniazid. Penelitian bersifat semi kuantitatif untuk mengetahui resistensi Mycobacterium sp. terhadap isoniazid dengan menggunakan metode rasio resistensi. Dasar dari metode ini adalah membandingkan minimal inhibitory concentration (MIC) dari strain Mycobacterium sp. dengan MIC dari isoniazid untuk M. tuberculosis strain H37RV. Hasil penelitian menunjukkan bahwa 40% dari total isolat adalah resisten, 20% adalah intermediate resistant dan 40% adalah sensitif. Disimpulkan bahwa telah terjadi resistensi Mycobacterium sp. terhadap isoniazid.Mycobacteria’s infection is one of the most difficult cured infection from all over kind of bacteria’s infection. The major pathogen mycobacteria is Mycobacterium tuberculosis, agent of tuberculosis (TB) that causes more deaths than other single microbes in the world. This research uses Mycobacterium sp. which clinically manifest as tuberculosis or tuberculosis-like disease. One of efforts to cure this infection is by using isoniazid. Single dose of isoniazid and failed use of isoniazid plus other suitable drug have resulted prevalence of isoniazid-resistant about 10-20% in clinical test in Caribbean and South East Asia. This research is aimed to know whether Mycobacterium sp. from RSSA Malang patients has been resistant toward isoniazid. This research uses a semi quasi experimental research to know the resis­tance of Mycobacterium sp. toward isoniazid by using resistance rasio method. This method compares minimal inhibitory concentration (MIC) of Mycobacterium sp. strain with MIC from isoniazid to M. tuber­culosis strain H37RV. Result of this research indicates that 40% from total isolates are resistant, 20% are intermediate resistant, and 40% are sensitive. The conclusion is Mycobacterium sp. has been resistant toward isoniazid.
