Emergency department (ED) management of the German STEC O104:H4 outbreak in 2011 was not limited to patients being truly infected with STEC. In parallel to spread of alarming news in public media, patients suffering from diarrhea due to other reasons fearfully presented, equally. We retrospectively characterized these two cohorts for anamnestic, clinical, and laboratory findings at their first ...

Shiga toxin--producing Escherichia coli (STEC) are a leading cause of bacterial enteric infections in the United States. Prompt, accurate diagnosis of STEC infection is important because appropriate treatment early in the course of infection might decrease the risk for serious complications such as renal damage and improve overall patient outcome. In addition, prompt laboratory identification o...

This present study is the first to report the presence of Shiga toxin-producing Escherichia coli (STEC) in buffaloes in Iran. A total of 360 fecal samples were collected from buffaloes from different regions in the west Azerbaijan province of Iran and cultured for the isolation of E. coli using routine biochemical tests. From the fecal samples, 340 E. coli were isolated and, of these, 26 STEC i...

Background Resistant Shiga toxigenic Escherichia coli (STEC), is the most prevalent source of diarrhea in pediatrics. This study was conducted to investigate the antimicrobial resistance properties of STEC strains of diabetic and non-diabetic pediatrics with diarrhea. Materials and Methods: This was a case-control study conducted from December 2014 to September 2015 in an educational hospital, ...

Shiga-toxin-producing Escherichia coli (STEC) of different serotypes are known to harbour large plasmids. The aim of this study was to investigate, using the example of the plasmid-encoded serine protease EspP, whether these plasmids are a uniform genetic element present in STEC. Examination of 201 diarrhoeagenic E. coli strains using a newly developed espP-specific PCR showed that espP is spec...

The serotype, Shiga toxin (Stx) type, and antimicrobial resistance patterns of 138 Stx-producing Escherichia coli (STEC) strains isolated from humans between 2003 and 2007 in Shizuoka Prefecture, Japan were characterized. The predominant O serogroups of the STEC isolates were O157, O26, and O111. Antimicrobial susceptibility testing of the STEC isolates showed that 31 of the 138 isolates (2...

This study was conducted to determine the prevalence of antimicrobial resistance in Shiga toxin-producing Escherichia coli (STEC) O157 (n = 241) and O26 (n = 11) isolated from beef cattle and to characterize their antimicrobial resistance profiles. Resistance to dihydrostreptomycin was detected most frequently (STEC O157, 9.5%; STEC O26, 54.5%), followed by resistance to oxytetracycline (7....

Shiga toxin-producing Escherichia coli (STEC) O157:H7 is an important foodborne pathogen worldwide. In Turkey, little is known about the molecular characteristics of STEC O157:H7 isolates. The aim of this study was to examine the genetic diversity of STEC O157:H7 isolates from cattle in Turkey using pulsed-field gel electrophoresis (PFGE). A total of 18 STEC O157:H7 strains were isolated from 5...

The incidence of the non-O157 enterohemorrhagic Escherichia coli (EHEC) nonO157:H7 Shiga toxin-producing E. coli (STEC) infections increased in the last years. Many serotypes of this toxigenic E.coli group were isolated from hemolytic uremic syndrome (HUS) and hemorrhagic colitis (HC) cases. The STEC strains possess many virulence factors codified by plasmids. Among the over 200 non-O157 STEC s...

*Corresponding author: Tel: +81-18-832-5005, Fax: +81-18-8325938, E-mail: [email protected] Shiga toxin (stx)-producing Escherichia coli (STEC) is an important cause of hemorrhagic colitis (HC) and hemolyticuremic syndrome (HUS) in humans (1). STEC O157:H7 is the serotype most commonly isolated from HUS patients, but non-O157 STEC have also been implicated in HC and HUS cases (2,3). C...
