چکیده مقاله :
سابقه و هدف: آلژینات، یکی از مهمترین عوامل بیماری زایی سودوموناس آئروجینوسا است. این مطالعه با هدف سنجش اثر هم افزایی آلژینات لیاز نوترکیب باکتریایی و آنتی بیوتیک های رایج در درمان عفونت های سودوموناسی بر رشد سلول های پلانکتونی سودوموناس آئروجینوسا انجام شد.مواد و روش‌ها: در مطالعه حاضر سودوموناس آئروجینوسا TAG48 از نمونه بالینی جدا سازی و شناسایی شد. به منظور تخلیص آنزیم آلژینات لیاز و اثر آن بر سلول های پلانکتونی، ژن آلژینات لیاز (algL) جداسازی، همسانه سازی، تعیین توالی و بیان شد و با استفاده از ستون کروماتوگرافی تمایلی تخلیص گردید. اثر آنزیم خالص شده و آنتی بیوتیک های سیپروفلوکساسین، توبرامایسین و سفکسیم بر سلول های پلانکتونی سودوموناس آئروجینوسا بررسی شد و آزمون های حداقل غلظت مهاری، حداقل غلظت کشندگی و همچنین بررسی اثر توام آنتی بیوتیک ها و آنزیم بر سلول های یاد شده ارزیابی شد.یافته‌ها: بررسی آنتی بیوتیک ها و آنزیم نشان دادند که MIC مربوط به سیپروفلوکساسین، توبرامایسین، سفکسیم و آنزیم آلژینات لیاز در باکتریTAG48 به ترتیب 4، 16، 128 و 9.37 میکروگرم بر میلی لیتر می باشد. میزان MBC نیز برابر با MIC محاسبه گردید. همچنین نتایج نشان داد که آلژینات لیاز با توبرامایسین و سفکسیم بر رشد سلول های پلانکتونی سودوموناس آئروجینوسا TAG48 اثرهم افزایی مهاری دارند، اما این اثر هم افزایی با سیپروفلوکساسین دیده نشد.نتیجه گیری: با توجه به اهمیت آلژینات در بیماری زایی سودوموناس آئروجینوسا، تخریب آن می تواند در کاهش بیماری زایی موثر باشد. شناسایی ژن های جدید algL در جوامع میکروبی می تواند رویکرد جدیدی برای مطالعه و تحقیق آلژینات لیاز هایی با فعالیت های ویژه علیه آلژینات های باکتریایی در نمونه های میکروبی بالینی باشد.
Background & Objectives: Alginate is one of the most important virulence factors of Pseudomonas aeruginosa. This study aimed to evaluate the synergistic effect of recombinant alginate lyase and common antibiotics in the treatment of Pseudomonas infections on the growth of planktonic cells of P. aeruginosa. Materials & Methods: In this study, P. aeruginosa TAG48 was isolated and identified from the clinical sample. To purify alginate lyase and its effect on planktonic cells, the alginate lyase gene (algL) was isolated, cloned, sequenced and expressed. The resultant enzyme was purified by affinity chromatography. The ciprofloxacin, tobramycin, and cefixime were also used to test the effectiveness of these antibiotics on planktonic cells of P. aeruginosa by carrying out MIC, MBC. The synergistic effects of these antibiotics and the recombinant alginate lyase enzyme on planktonic cells were evaluated. Results: Our results indicated that the antibiotics and the enzyme have shown MIC for ciprofloxacin, tobramycin, cefixime and enzyme in the following concentrations: 4, 16,128 and 9.37 μg/ml, respectively. MBC was also calculated equal to MIC. Also, alginate lyase exhibited synergy with tobramycin and cefixime on the growth of planktonic cells of P. aeruginosa TAG48 but not with ciprofloxacin. Conclusion: Regarding the importance of alginate in the pathogenicity of P. aeruginosa, its degradation could reduce this characteristic of the bacteria. Detection of novel algL genes in bacterial communities can also lead the way for the study of alginate lyases with specific activities against alginates from pathogenic bacteria in microbial samples.
