Interpretive Summary: Escherichia coli is a common member of the food animal gastrointestinal community. Some of these strains are pathogenic to humans, but most are not. The common diseases associated with exposure to the pathogenic strains are intestinal infections that are typically self-limiting, but can sometimes cause severe disease and death, or extraintestinal infections such as urinary tract infections (UTIs). Here we describe the genome of an Escherichia coli isolate that is assigned to the sequence type 38 (ST38). Strains of this sequence type are associated with extraintestinal infections globally. The results of this analysis demonstrate that this isolate encodes multiple virulence factors involved in human infections and is susceptible to antibiotics. These data help to increase our understanding of the diversity of potential human pathogens that can be carried by food animals and potentially contaminate the milk or meat supply, as well as the environment. The scientific community can utilize these data to identify potential interventions and decrease the burden of human pathogens in food animals.
Technical Abstract: Escherichia coli is a diverse species of commensal and pathogenic strains, some of which can cause gastrointestinal or extraintestinal infections. ST38 strains are frequently associated with extraintestinal infections and here we report the genome sequence of an ST38 strain that was isolated from a composite fecal sample on a commercial dairy farm.
