This study aimed to investigate the distribution of STEC in shellfish from coastal shores of Lake Timsah in Ismailia Governorate, Egypt and its probable hazard to seafood consumers. Samples from the external surface and tissues of shrimp (<jats:italic>n<\/jats:italic>\u2009=\u200945), crabs (<jats:italic>n<\/jats:italic>\u2009=\u200945), and oysters (<jats:italic>n<\/jats:italic>\u2009=\u200945) batches were examined bacteriologically for the presence of STEC and tested for their antibiotic sensitivity. Moreover, occurrence of virulence genes was determined via detection of <jats:italic>stx1<\/jats:italic>, <jats:italic>stx2<\/jats:italic> and <jats:italic>eaeA<\/jats:italic> genes using PCR. Overall, <jats:italic>E. coli<\/jats:italic> and presumptive STEC isolates (from CHROMagar) were identified from the surface (55.6 and 5.9%) and tissues (42.2 and 8.9%) of the examined shellfish batches, respectively. Five STEC isolates had been confirmed and found belonging to O26:H11, O125:H6, O146:H21, and O159 serogroups, those were 4 isolates from tissues of the three shellfish species and one isolate from the crab surface. The STEC isolates were multi-drug resistant, showing complete resistance to; penicillins, amoxycillin\/clavulanic acid, colistin, fosfomycin, ceftriaxone, ciprofloxacin, and tetracycline, however, they were sensitive to gentamycin except O159 serogroup. The current study revealed low level of contamination of shellfish from coastal shores of Lake Timsah with STEC, however, it also highlights the extreme level of antimicrobial resistance exhibited by the presumptive and confirmed STEC isolates which is very hazardous for seafood consumers in the study area.<\/jats:p>","DOI":"10.1007\/s00203-022-03114-2","type":"journal-article","created":{"date-parts":[[2022,7,21]],"date-time":"2022-07-21T19:03:47Z","timestamp":1658430227000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Virulence and antimicrobial-resistance of shiga toxin-producing E. coli (STEC) Isolated from edible shellfish and its public health significance"],"prefix":"10.1007","volume":"204","author":[{"given":"Dheyazan M.
