coli O157:H7. A well-known phenotypic characteristic of E. coli O157:H7 bacteria is their inability to ferment sorbitol. This characteristic is often used to isolate these organisms from food and water using selective agar medium such as SMAC. However, the high number of false positive results...
GB 4789.36规定:E. coli O157:H7 分离须同时采用CT-SMAC和显色培养基。默克西格玛ChromoSelect培养基的显色底物能选择性地被E. coli O157:H7分解,菌落呈特异性紫色。非O157的E. coli及其他大肠菌群呈蓝绿色。

coli O157:H− 431/97 in in vivo plant experiments. The investigated strain was already differentiated from the autochthonous micro- biota as well as closely related pathogens such as Sal- monella and Shigella on SMAC agar by its ability to metabolize sorbitol. This is not the case for ...
大肠杆菌E. coli 是大肠菌群的代表菌属。大多数E. coli是非致病的,在动物和人类肠道内正常寄居。小部分特殊血清型的大肠杆菌是条件致病菌,可引发胃肠道感染,严重时发生败血性感染, 血性腹泻和溶血性尿毒综合症等。其中代表性血清型是E. coli O157:H7/NW。生牛肉是E. coli O157爆发最常见的感染源。
Keywords: Escherichia coli O157:H7; lettuce; gene expression; preharvest 1. Introduction Leafy vegetables, such as lettuce, are considered a high-risk food since numerous outbreaks with enteric pathogens have been linked to the consumption of these products [1]. Escherichia coli O157:H7 (E. coli...

Frequency of Escherichia coli O157:H7 in Turkish Cattle In this study, five abattoirs in Istanbul were visited between January 2000 and April 2001. During these visits, 330 cattle were selected by a systematic sampling method. Cattle were examined elinically and breed, age, and sex were recor...
coli O157:H7-GFP Representative cultures that tested positive for GFP by PCR analysis were also plated on CT-SMAC (cefixime tellurite sorbitol MacConkey agar) plates to confirm the presence of E. coli O157:H7 in the sample. The cultures (100 μL) were plated on Sorbitol MacConkey agar (...
