“…Notably, the O serotypes O3, O15, O81, O116, O129, and O140 of cattle isolates here were rarely reported to be present in sheep isolates (Blanco et al, 2003;Martins et al, 2015;Oporto, Esteban, Aduriz, Juste, & Hurtado, 2008). O129, which was formerly suggested to be EPEC, was not reported in cattle isolates in previous studies, although it was earlier isolated from human feces (Blanco et al, 2006;Schwaiger, Grif, Pierard, Karch, & Allerberger, 1999). Some serogroups share a common ancestor with other pathotypes such as EPEC and EAEC, and integration of astx -containing bacteriophage may convert these into a more virulent variant (Steyert et al, 2012).…”

Shiga toxin-producing Escherichia coli (STEC) is an important foodborne pathogen capable of causing severe gastrointestinal diseases in humans. Cattle and sheep are the natural reservoir hosts of STEC strains. Previously, we isolated 56 STEC strains from anal and carcass swab samples of cattle and sheep in farms and slaughterhouses. In this study, we performed whole-genome sequencing of these isolates and determined their serotypes, virulence profiles, sequence types (STs), and genetic relationships. Our results showed that the 56 isolates belong to 20 different STs, 29 O:H serotypes, and 8 stx subtype combinations. The highly prevalent serotypes were O8:H25 and O87:H16 for bovine and ovine isolates, respectively. Five serotypes of cattle or sheep isolates are novel. The majority (63%) of cattle isolates contain stx1+stx2, subtyped into stx1a, stx2a, and stx2c. In contrast, most of the sheep isolates contain stx1 only, primarily subtyped into stx1a and stx1c. None of the isolates tested eae-positive, but virulence factors such as ehxA and espP were present with variable prevalence rates. The prevalence of saa (19.6%) and espP (12.5%) in cattle isolates is much higher than that in sheep isolates, whereas that of subA (34%), katP (14.3%), and ireA (28.6%) in sheep isolates is considerably higher than that in cattle isolates. Core-genome SNP analysis revealed that the majority of isolates could be clustered based on their serotypes or STs, whereas some clustering is associated with more than one ST or serotype. Seven-gene Multilocus Sequence Typing (MLST) indicated that nine sheep isolates and four cattle isolates were related to a few E. coli isolates associated with human HUS, suggesting their potential in causing severe human infections. Collectively, we described the characteristics of cattle and sheep STEC isolates from Xinjiang, China, which may be utilized in comparative studies of other geographic regions and sources of isolation and for surveillance.

“…Schwaiger et al [23] tested 296 stool specimens sent to a laboratory in western Austria in 1998 and found EHEC to be the third most frequent bacterial cause of diarrhea, as did Allerberger et al [19] testing stool samples from 280 pediatric patients from the same catchment area in 1996. In a 1-year study of ''foodborne illnesses'' in Uppsala (Sweden), EHEC accounted for 8% of disease agents detected in feces (Campylobacter 24%, Salmonella 2%) [24].…”
