Çeşitli Klinik Örneklerden Izole Edilen Staphylococcus aureus Suşlarında Metisilin Direncinin Araştırılmasında Konvansiyonel PCR Yöntemi ile Sefoksitin Disk Difüzyon, Otomatize Sistem ve Chromogenic MRSA Agar Yöntemlerinin Karşılaştırılması
Öz
Metisiline dirençli Staphylococcus
aureus (MRSA) en önemli enfeksiyöz ajanlardan biridir. Bu nedenle MRSA'nın
hızlı ve doğru tanısı çok önemlidir. PCR ile mecA gen tespiti referans
metodu olmakla birlikte, basit olmasından dolayı rutin uygulamada geleneksel
yöntemler tercih edilmektedir. Geleneksel yöntemler ile tanının koyulması 48-96
saat sürdüğü için çeşitli kromojenik besiyerleri geliştirilmiştir.
Çalışmamızdaki amacımız metisilin direncinin tespitinde kullanılan çeşitli yöntemleri
PCR ile karşılaştırmaktır. Çeşitli klinik örneklerden izole edilen 48 S.
aureus suşu çalışmamıza dahil edilmiştir.48 S.aureus suşunun 19'u mecA
gen-pozitif ve 29'u negatiftir. mecA gen-pozitif 19 suş da otomatik
sistem ve disk difüzyonu ile dirençli bulunmuştur. Kromojenik agarda, 19
MRSA suşunun 15'i metisilin dirençli ve 4'ü duyarlı bulunmuştur.29 mecA
gen-negatif suş, otomatik sistem ve disk difüzyonu ile duyarlı bulunmuştur. mecA
geni negatif olan 29 MSSA suşunun kromojenik agarda 17’si dirençli olarak
değerlendirmiştir.

Comparison of Conventional PCR Method With Cefoxitin Disc Diffusion, Automated System and Isolation on Chromogenic MRSA Medium Methods for The Detection of Meticillin Resistance In Staphylococcus aureus Strains Isolated From Various Clinical Specimens
Öz
Meticillin-resistant Staphylococcus
aureus (MRSA) is one of the most important infectious agents. Therefore,
fast and accurate diagnosis of MRSA is utmost important. Although mecA
gene detection by PCR is reference method, conventional methods are preferred
in routine practices due to simplicity. As conventional methods last 48-96
hours, several chromogenic media have been developed. Our objective was to
compare the methods used for meticillin resistance detection with PCR.
Forty-eight S. aureus strains isolated from various clinical specimens
were included. Of the 48 S. aureus strains, 19 were mecA gene-positive
and 29 were negative. mecA gene-positive 19 strains were also
meticillin-resistant by automated system and disk diffusion. On chromogenic
agar, 15 of 19 MRSA strains were meticillin-resistant and 4 were
meticillin-sensitive. Twentynine mecA gene-negative strains were
susceptible to meticillin by automatized system and disk diffusion. Among 29 mecA
gene-negative MSSA strains inoculated on chromogenic agar, 17 were
methicillin-resistant. According to our study, chromogenic media would be
ineffective to detected to meticillin-resistance because of low sensitivity and
specificity in routine.
