مقدمه: آبزیان به دلیل کالری و پروتئین بالا و همچنین وجود چربی غیراشباع امگا ۳ از اهمیت بسزایی در سبد غذایی برخوردارند. در مراحل مختلف از زمان صید تا رسیدن به دست مصرف‌کننده، همواره ممکن است بسیاری از آبزیان از جمله ماهی به برخی از میکروارگانیسم‌های بیماری‌زا آلوده شوند و در نهایت مسمومیت شدید را برای افراد ایجاد نمایند. در پژوهش حاضر به بررسی ثبت و شناسایی ژن‌های توکسیک استافیلوکوکوس اورئوس جدا شده از ماهی تیلاپیا با تکنیک Multi plex PCR پرداخته شده است.مواد و روش‌ها: تعداد کل نمونه‌ها 42 عدد (21 عدد نمونه ماهی تازه و 21 عدد نمونه ماهی منجمد) مدنظر قرار گرفته شد. ابتدا پس از آماده‌سازی نمونه‌های مورد بررسی به ترتیب استافیلوکوکوس اورئوس جدا شد و به صورت کشت سطحی در محیط برد پارکر مورد بررسی قرار گرفت، سپس تست کوآگولاز انجام شد و در مرحله بعد با استخراج DNA ژن انتروتوکسیک شناسایی شد. در نهایت توالی‌یابی ژن به صورت اتوماتیک و دستگاهی انجام گرفت.یافته‌ها: یافته‌های به دست آمده نشان داد، 9/92 درصد از کل نمونه‌های مورد بررسی (21 عدد ماهی تیلاپیا تازه و 18 عدد ماهی منجمد) فاقد باکتری استافیلوکوکوس اورئوس بودند و 1/7 درصد از کل نمونه‌ها آلوده به باکتری استافیلوکوکوس اورئوس شدند. نتایج بررسی تست کوآگولاز نیز نشان داد، هر سه نمونه ماهی منجمد مورد بررسی، کوآگولاز مثبت بودند. پس از بررسی ژن‌های تولید‌کننده انتروتوکسیک (SEA، SEB، SEC، SED، SEE و SEG) در بین سه نمونه منجمد آلوده به باکتری استافیلوکوکوس مشاهده شد که تنها در یک نمونه منجمد، ژن انتروتوکسیک SEA وجود داشت.نتیجه گیری: نتایج نشان داد با توجه به هزینه کم و زمان بسیار کوتاه‌تر مورد نیاز برای شناسایی ژن های استافیلوکوکوس اورئوس با روش Multiplex PCR، این روش ابزار قدرتمندی برای مطالعه ژنوتیپ‌های جدایه‌های استافیلوکوک می‌باشد. بنابراین با استفاده از این روش می‌توان به ارتقا سطح سلامت غذایی در جامعه به خوبی پرداخت.
