Enteroinvasive Escherichia coli has not been extensively studied for cytotoxin production. We evaluated 30 well-characterized enteroinvasive E. coli strains of all the known invasive serogroups from several geographic regions for their ability to produce Shiga-like cytotoxic activity assayed in a HeLa cell system. None of these strains produced cytotoxic activity that was neutralizable with ant...
Shiga-toxigenic Escherichia coli (STEC) strains were isolated from 7.4% of 1,440 fecal and farm environmental samples. Shiga toxin gene and STEC prevalences were significantly associated with animal production type and season. A range of serogroups were identified. Nine percent of isolates possessed all three principal virulence markers: stx(2), eae, and ehx.
To inhibit protein synthesis and induce cell death, plant ricin toxin and bacterial Shiga toxins enter the cell through the endocytic and retrograde secretory pathways. Stechmann et al. (2010) now identify two small-molecule inhibitors that selectively block endosome-to-Golgi retrieval of ricin and Shiga toxins and protect mice from ricin's deadly effects.
Isolation of Shiga toxin-producing Escherichia coli harboring variant Shiga toxin genes from seafood
Shiga toxin-producing Escherichia coli (STEC) bacteria are foodborne pathogens that can be carried by various animals. The swine STEC population is partially composed of host-specific strains that are often not well characterized. In this work, the genome sequences of a number of swine STEC strains are presented.
This study aimed to verify the occurrence of Shiga toxin-producing Escherichia coli (STEC) strains in three distinct anatomic parts of the stable fly Stomoxys calcitrans by multiplex polymerase chain reaction (PCR Multiplex). According to the results obtained, E. coli was identified in 19.5% of the stable flies. Shiga toxin genes were detected in 13% of the E. coli isolated, most frequently fro...
Shiga toxin type 2 (Stx2) produced by Escherichia coli O:157H7 can cause hemolytic-uremic syndrome in children, a disease for which there is neither a vaccine nor an effective treatment. This toxin consists of an enzymatically active A subunit and a pentameric B subunit responsible for the toxin binding to host cells, and also found to be immunogenic in rabbits. In this study we developed eukar...
BACKGROUND The BD MAX™ Enteric Bacterial Panel (BDM-EBP) is designed and FDA-cleared to detect Salmonella, Shigella, Campylobacter, and Shiga toxin genes stx1/2 from stool samples. However, rectal swabs, which are not FDA-cleared for clinical testing with the BDM-EBP, are common specimens received from pediatric patients for enteric pathogen testing. The purpose of this study was to evaluate th...
