The emergence of multidrug-resistant (MDR) STEC from cattle sources has increased public health risk and limited treatment options. The prevalence of STEC was investigated in 200 raw food samples (milk and beef samples) and 200 diarrheic samples (cattle and human samples) in a matched region.

Antibiogram and Enterobacterial repetitive intergenic consensus (ERIC)-PCR were also conducted. STEC isolates were identified in 6.5% (13\/200) of food samples [6% (6\/100) of milk and 7% (7\/100) of beef samples] and in 11% (22\/200) of diarrheic cases [12% (12\/100) of cattle and 10% (10\/100) of human samples]. We found that O26 (4.5%, 18\/400) and O111 (1.5%, 6\/400) were the most prevalent STEC serovars and were found more commonly in diarrheic samples. STEC strains with both\n                    <jats:italic>stx<\/jats:italic>\n                    genes,\n                    <jats:italic>stx2<\/jats:italic>\n                    only, and\n                    <jats:italic>stx1<\/jats:italic>\n                    only genotypes were present in 62.9% (22\/35), 20% (7\/35), and 17.1% (6\/35) of isolates, respectively. Carbapenemase-producing STEC (CP STEC) isolates were found in 1.8% (7\/400) of samples [0.5% (1\/200) of foods and 3% (6\/200) of diarrheic cases].

Approximately half (51.4%, 18\/35) of STEC isolates were MDR STEC; all CP STEC and ESBL-producing STEC were also MDR STEC. The highest antimicrobial resistance rates were found against nalidixic acid (51.4%) and ampicillin (48.6%), whereas the lowest rates were reported against gentamicin (5.7%) and ciprofloxacin (11.4%). MDR STEC strains were 5.3 times more likely to be found in diarrheic cases than in foods (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u20090.009, 95% CI 1.5\u201318.7). ERIC-PCR was used for genotyping STEC isolates into 27 different ERIC-types (ETs) with a discrimination index of 0.979. Five ETs showed clusters of 2\u20134 identical isolates that shared the same virulence and antibiotic resistance genetic profile. Human isolates matched food isolates in two of these ET clusters (the O26 CP STEC cluster and the O111 STEC cluster), highlighting the potential cross-species zoonotic transmission of these pathogens and\/or their genes in the study region. This is the first detection of CP STEC in milk and diarrheic cattle in Egypt.\n                  <\/jats:p>","DOI":"10.1186\/s13099-021-00402-y","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T04:12:55Z","timestamp":1612498375000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Prevalence, antimicrobial resistance, and genotyping of Shiga toxin-producing Escherichia coli in foods of cattle origin, diarrheic cattle, and diarrheic humans in Egypt"],"prefix":"10.1186","volume":"13","author":[{"given":"Walid","family":"Elmonir","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samar","family":"Shalaan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amin","family":"Tahoun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samy F.","family":"Mahmoud","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etab M.
