چکیده مقاله :
سابقه و هدف: سودوموناس آئروجینوسا یک پاتوژن فرصت طلب به ویژه در بیماران با نقص ایمنی است. مقاومت دارویی در سودوموناس آئروجینوسا به واسطه مکانیسم های مختلفی مانند جهش در زیرواحدهای توپوایزومرازها و تنظیم کننده های منفی سیستم های پمپ افلاکس ایجاد می شود. هدف از این مطالعه ارزیابی جهش های نقطه ای ژن های gyrB، parC و nfxB در جدایه های سودوموناس آئروجینوسا مقاوم به سیپروفلوکساسین استان گیلان بود.مواد و روش ها: این پژوهش یه صورت مقطعی—توصیفی بر روی 200 سویه جمع آوری شده از بیمارستان ها و آزمایشگاه های رشت و لاهیجان انجام شد. با آزمون های بیوشیمیایی تعیین هویت جدایه ها انجام شد. حساسیت آنتی بیوتیکی به کمک روش های کربی-بائر و MIC تعیین گردید. برای ارزیابی جهش ها در ژن های gyrB، parC و nfxB در جدایه های مقاوم به سیپروفلوکساسین از روش PCR و تعیین توالی استفاده شد.یافته ها: از 69 جدایه سودوموناس آئروجینوسا، 26 سویه مقاوم به سیپروفلوکساسین بودند. MIC سیپروفلوکساسین در جدایه های مقاوم بین µg/ml 32-1024 تعیین گردید. با آنالیز توالی یابی مشخص گردید که بعضی از جدایه های مقاوم، جهش های بدمعنی در ژن های gyrB، parC و nfxB داشتند. جهش های N368S، I424L، L464I، E468D، M520L و I524V در ژن gyrB اولین موارد گزارش شده در ایران می باشند.نتیجه گیری: به نظر می رسد که جهش های گزارش شده در ژن های gyrB و parC روی تمایل توپوایزومرازها به سیپروفلوکساسین در جدایه های مقاوم تأثیر بگذارند. همچنین، جهش در ژن nfxB ممکن است موجب افزایش بیان پمپ افلاکس MexCD-OprJ و مقاومت به سیپروفلوکساسین گردد.
Background & Objectives: Pseudomonas aeruginosa is an opportunistic pathogen especially in immunocompromised patients. Drug resistance in P. aeruginosa is caused by different mechanisms such as mutations in topoisomerases subunits and negative regulators of efflux pump systems. This study was aimed to investigate mutations in gyrB, parC, and nfxB genes in ciprofloxacin-resistant P.aeruginosa isolates in Guilan province. Materials & Methods: In this cross-sectional study, 200 isolates were obtained from different clinical samples of Rasht and Lahijan hospitals and laboratories and subsequently identified by biochemical tests. Antibiotic susceptibility pattern was determined by Kirby Bauer disk diffusion susceptibility test and Minimum Inhibitory Concentration (MIC) test. PCR-sequencing was used to assess mutations in gyrB, parC, and nfxB genes in ciprofloxacin-resistant P. aeruginosa isolates. Results: Out of 69 P. aeruginosa isolates, 26 isolates were ciprofloxacin-resistant. MIC of ciprofloxacin in resistant isolates was determined between 32-1024 µg/ml. PCR-sequencing analysis revealed that some resistant isolates have missense mutations in gyrB, parC, and nfxB genes. It seems that N368S, I424L, L464I, E468D, M520L, and I524V mutations in gyrB were reported for the first time in Iran. Conclusion: It seems that reported mutations in gyrB and parC genes affect topoisomerases affinity to ciprofloxacin in resistant isolates. Furthermore, mutations in the nfxB gene may lead to overexpression of MexCD-OprJ efflux pump and ciprofloxacin resistance.
