Abstract
Shiga toxin-producing Escherichia coli strains are worldwide associated with sporadic human infections and outbreaks. In this work, we report the availability of high-quality draft whole-genome sequences for 19 O157:H7 strains isolated in Argentina.
Highlights
Shiga toxin-producing Escherichia coli (STEC) strains are a common cause of both sporadic infections and food and waterborne outbreaks
Previous studies have shown that O157:H7 strains belonging to clade 8 and lineage I/II by lineage specific polymorphism assay (LSPA-6) are prevalent in human and cattle isolates
This work reports the availability of high-quality draft wholegenome sequences for 19 (11 human and eight bovine) O157:H7 strains isolated in Argentina
Summary
Shiga toxin-producing Escherichia coli (STEC) strains are a common cause of both sporadic infections and food and waterborne outbreaks. In Argentina, hemolytic uremic syndrome (HUS) is endemic with approximately 400 new cases reported annually. STEC O157:H7 is the dominant serotype and stx2a/stx2c the prevalent genotype. The main source of O157 is cattle.
