Non-O157 Shiga toxin-producing Escherichia coli (STEC) strains are clinically important foodborne pathogens. Unlike E. coli O157:H7, these foodborne pathogens have no unique biochemical characteristics to readily distinguish them from other E. coli strains growing on plating media. In this study, a chromogenic agar medium was developed in order to differentiate among non-O157 STEC strains of s...

An antibody microarray was developed to detect the "top six" non-O157 serogroups, O26, O45, O103, O111, O121, and O145 of Shiga toxin-producing Escherichia coli (STEC), that have been declared as adulterant in meat by the Food Safety and Inspection Service of the United States Department of Agriculture. The sensitivity of the array was 10(5)CFU and the limit of detection of each serogroup in ar...

Over the past few years, foodborne disease outbreaks linked to enteric pathogens present on cantaloupe and watermelon surfaces have raised concerns in the melon industry. This research evaluated the effectiveness of commercially available produce sanitizers against selected foodborne pathogens, both in cell suspensions and on the outer rind surface of melons. The sanitizers (65 and 200 ppm of c...

Shiga toxin-producing Escherichia coli (STEC) strains are important food-borne pathogens that have been linked to human illness. In the United States, STEC O157:H7 strains have been attributed to the majority of disease and outbreaks; however, the frequency of disease associated with STEC non-O157 strains have also increased and is often under recognized due to diagnostic limitations. In 2012, ...

A substantial number of patients with heart failure (HF) have preserved left ventricular ejection fraction (LVEF), variably defined as an LVEF O40%, O45%, or O50%. When these patients have invasive or non-invasive evidence of abnormal diastolic function (either abnormal relaxation, filling or stiffness) they are said to have ‘‘diastolic HF’’. Although the term ‘‘HF with normal LVEF’’ is often u...

Aim The present study was conducted to detect the occurrence, serogroups, virulence genes and phylogenetic relationship of shiga toxin-producing Escherichia coli (STEC) in human, clave and goat in Kerman (southeast of Iran). Background STEC have emerged as the important foodborne zoonotic pathogens causing human gastrointestinal disease and confirming the risk to public health. Methods A to...
