Whole-genome sequencing for national surveillance of Shiga toxin–producing Escherichia coli O157 [PDF]

, 2015
Background. National surveillance of gastrointestinal pathogens, such as Shiga toxin–producing Escherichia coli O157 (STEC O157), is key to rapidly identifying linked cases in the distributed food network to facilitate public health interventions.

Estandarización de una técnica de PCR múltiple para la detección de los serogrupos O157, O104 y “big six” de Escherichia coli productora de la toxina Shiga (STEC)

Memorias del Instituto de Investigaciones en Ciencias de la Salud, 2019
Los serogrupos O26, O45, O103, O104, O111, O121, O145 y O157 de STEC se relacionan con un elevado número de casos de SUH a nivel mundial, por lo que están incluidos dentro de las categorías de mayor riesgo para los humanos, según los criterios de ...

Comparison of IRI-Plas STEC and IONOLAB-STEC Over a Midlatitude GPS Network

2019 9th International Conference on Recent Advances in Space Technologies (RAST), 2019
Total Electron Content (TEC) is an important parameter of the ionosphere used to investigate and determine the ionospheric variability. Slant Total Electron Content (STEC) is the total number of electrons between the receiver-satellite link. International Ionosphere (IRI) Extended to Plasmasphere (IRI-Plas) is an internationally accepted climatic model

Improved Genomic Identification, Clustering, and Serotyping of Shiga Toxin-Producing Escherichia coli Using Cluster/Serotype-Specific Gene Markers

Frontiers in Cellular and Infection Microbiology, 2022
Shiga toxin-producing Escherichia coli (STEC) have more than 470 serotypes. The well-known STEC O157:H7 serotype is a leading cause of STEC infections in humans. However, the incidence of non-O157:H7 STEC serotypes associated with foodborne outbreaks and

Subtyping of STEC by MLVA in Argentina [PDF]

Frontiers in Cellular and Infection Microbiology, 2012
Shiga toxin-producing Escherichia coli (STEC) causes serious human illness such as hemolytic uremic syndrome (HUS). Argentina has the world's highest rate of this syndrome, which is the leading cause of acute renal failure among children. E. coli O157:H7 is the most common cause of HUS, but a substantial and growing proportion of this illness is caused

Identification of the long polar fimbriae gene variants in the locus of enterocyte effacement-negative Shiga toxin-producing Escherichia coli strains isolated from humans and cattle in Argentina [PDF]

, 2010
The long polar fimbriae (Lpf) is one of few adhesive factors of Shiga toxin-producing Escherichia coli (STEC) and it is associated with colonization of the intestine. Studies have demonstrated the presence of lpf genes in several pathogenic E.

Whole-Genome Phylogenetic Analysis Reveals a Wide Diversity of Non-O157 STEC Isolated From Ground Beef and Cattle Feces

Frontiers in Microbiology, 2021
Shiga toxin-producing Escherichia coli (STEC) causes foodborne outbreaks that can lead to complications such as hemolytic uremic syndrome. Their main reservoir is cattle, and ground beef has been frequently associated with disease and outbreaks.

Occurrence and characterization of shiga toxin-producing Escherichia coli in raw meat, raw milk, and street vended juices in Bangladesh [PDF]

, 2010
The major objective of this study was to investigate the prevalence of Shiga toxin (Stx)–producing Escherichia coli (STEC) in different types of food samples and to compare their genetic relatedness with STEC strains previously isolated from animal ...
