[ 6 ] - شناسایی سروتایپ های سالمونلا در طغیان های غذایی با استفاده از سکانس ناحیه ی ITS ژن 16S-23S rRNA

زمینه و هدف: بیماری های منتقله از غذا یکی از مشکلات جامعه ی امروزی است. در بسیاری نقاط جهان˓ بررسی های اپیدمیولوژی نشان داده است که عفونت های ناشی از سرووارهای سالمونلا افزایش یافته است. بدین منظور شناسایی سویه های سالمونلا در سطح سرووار از اهمیت خاصی برخوردار است. ظهور سویه های مقاوم در این سرووارها به یک نگرانی جهانی تبدیل شده است، بنابراین آگاهی از الگوی مقاومتی در سالمونلاها می تواند به در...

[ 7 ] - بررسی خاصیت آنتی باکتریال کوکتل باکتریوفاژ نسبت به برخی سروتیپ های باکتری سالمونلا انتریکا (انتریتیدیس، تیفی موریوم، اینفنتیس) در مقایسه با سیپروفلوکساسین درشرایط in vitro برای اولین بار در ایران

Background: Salmonellosis is a gastroenteritis caused by the infection with different serotypes of Salmonella. Salmonella enterica is an enterica subtype, enteritidis, typhimurium, and infantis are the most important factors of gastroenteritis in humans. In recent years, increasingly commonly used antibiotics and treatments are resistant. The main purpose of this study was to compare the antiba...

[ 8 ] - Antimicrobial resistance pattern of citrobacter species isolated from food outbreaks

Background:   Foodborne diseases and resistance to antimicrobial agents are two of the world's most widespread global issues. Also, the excessive use of antibiotics has led to the resistance of bacteria belonging to the Enterobacteriaceae family to antibiotics, especially in carbapenems. Citrobacter is an opportunistic bacterium that is resistant to antibiotics in the emerging bacteria and has ...
