چکیده
Background and Aim:Pseudomonas aeruginosa is a gram negative, bacillary shape, non-spore forming, ubiquitous opportunistic bacterium present in many various environmental settings in different geographical regions, and it can be isolated from diverse living sources, such as humans, animals, and plants. The goals of the current multicenter research were to assess virulence factors genes among the P.aeruginosa clinical isolates.Methods:Pseudomonas aeruginosa isolates were recovered from inpatients. Bacterial identification was done by standard diagnostic tests, and species was confirmed by detection of exoA gene by PCR technique. Virulence markers were detected by PCR.Results:Among surveyed isolates, plcH+, lasB+ genotype (100% isolates) were the most common virulence genes patterns. Thirty-nine (48.75%) out of 80 P.aeruginosa isolates showed algD+, plcH+, lasB+, IMP+genotype. The blaIMP resistance gene was detected in all MHT positive and MDR isolates. Another interesting finding in our study was the more frequent occurrence of algD+, MDR, MHT+ and blaIMP+ strains among the Pseudomonas aeruginosa isolates from Yasuj compared with those from Shiraz.Conclusion:Emergence of multi-drug resistant P. aeruginosa, especially to carbapenems and aminoglycosides, and the high prevalence of virulence traits in our study could be regarded as an alarming situation.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
