Quantification and evaluation of infectivity of shiga toxin-encoding bacteriophages in beef and salad.
نویسندگان
چکیده
Stx bacteriophages in 68 samples of beef and salad were quantified by real-time quantitative PCR (qPCR). Stx phages from the samples were propagated in Escherichia coli C600, E. coli O157:H7, and Shigella strains and further quantified. Fifty percent of the samples carried infectious Stx phages that were isolated from plaques generated by lysis.

Persistence of infectious Shiga toxin-encoding bacteriophages after disinfection treatments.
In Shiga toxin-producing Escherichia coli (STEC), induction of Shiga toxin-encoding bacteriophages (Stx phages) causes the release of free phages that can later be found in the environment. The ability of Stx phages to survive different inactivation conditions determines their prevalence in the environment, the risk of stx transduction, and the generation of new STEC strains. We evaluated the i...
متن کاملPrevalence of Multidrug Resistant Shiga Toxin-Producing Escherichia coli in Cattle Meat and Its Contact Surfaces
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...
متن کاملDetection and Molecular Characterization of Sorbitol Negative Shiga Toxigenic Escherichia Coli in Chicken from Northwest of Iran
Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. STEC has been found to produce a family of related cytotoxins known as Shiga toxins (Stxs). Shiga toxins have been classified into two major classes, Stx1 and Stx2. A single strains of STEC can produce St...
متن کاملHigh stability of Stx2 phage in food and under food-processing conditions.
Bacteriophages (phages) carrying Shiga toxin genes constitute a major virulence attribute in enterohemorrhagic Escherichia coli (EHEC). Several EHEC outbreaks have been linked to food. The survival of such strains in different foods has received much attention, while the fate of the mobile Shiga toxin-converting phages (Stx phages) has been less studied. We have investigated the stability of an...
متن کاملComprehensive Evaluation and Implementation of Improvement Actions in Butcher Shops
Foodborne pathogens can cause acute and chronic diseases and produce a wide range of symptoms. Since the consumption of ground beef is a risk factor for infections with some bacterial pathogens, we performed a comprehensive evaluation of butcher shops, implemented improvement actions for both butcher shops and consumers, and verified the impact of those actions implemented. A comprehensive eval...
