Virulence Profiling and Molecular Typing of Shiga Toxin-Producing E. coli (STEC) from Human Sources in Brazil

Microorganisms, 2020
Since no recent data characterizing Shiga toxin-producing E. coli (STEC) from human infections in Brazil are available, the present study aimed to investigate serotypes, stx genotypes, and accessory virulence genes, and also to perform pulsed-field gel ...

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

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.
