این مطالعه جهت ارزیابی پنیرهای سنتی تولید شده در استان چهار محال و بختیاری و آلودگی به سروتیپ E. coli 7:H157O که به عنوان یکی از مهمترین سروتیپهای بیماریزای انسان در سالهای اخیر معرفی شده است طراحی و با اخذ نمونههای تصادفی از مکانهای تولید و توزیع این فراورده به اجرا گذارده شد. ابتدا نمونههای پنیر(200 نمونه) در محیط غنی کننده انتخابی آبگوشت اشریشیا حاوی آنتی بیوتیک نوبیوسین کشت داده شد و ...
A survey of the microbial quality based on enterobacteriaceae counts of the table eggs sold in Egyptian markets was conducted to evaluate their quality and the possibility of presence of Enterovirulent Escherichia coli strains. Six hundred random table egg samples were collected from different shops, supermarkets and homes. Each six pooled eggs constituted a composite sample. Higher enterobacte...
Monoclonal antibodies (MAbs) against five putative colonization factors (PCFs), i.e., colonization factor antigen (CFA)/III, coli surface antigen (CS)7 and CS17, PCFO159, and PCFO166 of enterotoxigenic Escherichia coli (ETEC), were produced. Hybridomas (one each) producing specific antibodies against the respective PCFs were selected. All the MAbs reacted with the corresponding fimbriae but not...
Received at: 18/8/2013 Accepted: 23/10/2013 A total of 105 cases of broilers were collected from broiler flocks showing high mortality rates in Sharkia Governorate. E. coli was isolated from 84 (80%) cases. A number of 11 different serotypes were identified, of which O114:K90 was the most detected with 17.9% of the total isolates. While O125:K70, O55:K59, O111:K58 and O26:K60 were identified wi...
INTRODUCTION Fresh produce has been implicated in a number of documented outbreaks of foodborne illness caused by bacteria, viruses, and parasites. Shiga toxin-producing Escherichia coli (STEC) have been detected on vegetables, raising concerns about the prevalence of E. coli contamination in produce, which can take place at various points from farm to fork. This study aimed to detect the prese...
Background and Objective: Escherichia coli (E-coli) is a normal gram negative organism that inhabit the human and animal intestinal tract. Pap G gene has an important role in creating P -fimbriae tip and in producing septicemia and urinary tract infection. The aim of this study was to investigate the presence of pap G gene in EPEC strains isolated from urine and blood. Materials and Metho...
Background: Shiga toxin-producing Escherichia coli (STEC) are group of E. coli causing bloody diarrhea. The goal of this survey was to determine the prevalence of multidrug resistant shiga toxin-producing E. coli in cattle meat and its contact surfaces. Methods: Swab samples (n=120) were randomly collected from meat and contact surface of butchery shops in Sharkia province, Egypt. Prevalence o...
به منظور بررسی میزان آلودگی پنیر سنتی سفید کازرون به کلی فرم ها و اشریشیا کولای ، طی سه ماه فروردین ، اریبهشت و خرداد 84 از کلیه فروشگاههای لبنیات کازرون 50 نمونه تهیه شد. برای جداسازی ، تشخیص و شمارش کلی فرم اشریشیا کولای استانداردهای ملی مد نظر قرار گرفت. نتیجه آزمایشهای میکروبی به صورت زیر بود: از 50 نمونه پنیر مورد آزمایش ،49 نمونه (98%) به کلی فرم ها آلوده بودندکه در این میان 40 نمونه (80%...
a three month-old-male red deer calf (cervus elaphus maral) was examined post mortem for the cause of death in arasbaran preserved area in east azerbaijan in september 2006. the main history of the case was the lack of colostrum intake after birth. the necropsy 6 hours after death, revealed severe general congestion especially in lungs and visceral organs (liver and jejunum). the cut surface of...
in modern medical processes, new antimicrobial drugs are being widely used in order to rapid and essential eradication of resistant bacterial strains. broad-spectrum beta-lactamases are enzymes originated from mutations in the common plasmid genes mediators for beta-lactamases such as tem-1, tem-2, and shv-1 are transferred among bacterial species. the genes coding the production of esbl are of...
