A study of pathogenic  Escherichia coli in Sarda sheep at slaughter, on  carcasses, fleeces, gut and faeces was performed.  Nineteen sampling sessions were carried out in  industrial capacity slaughterhouses. The aim of the  present study was to evaluate the role of the sheep  as STEC reservoir and to detect the prevalent  serogroups over the sheep chain production. In order  to make a preliminary screening of STEC in collected  samples, a simplex PCR was performed on all the  specimens. Virulence profile characterization of the  isolates showed a significant level of STEC strains  (22.6%) and a higher number of EPEC (53.8%).  Furthermore, virulence accessory factors are widely  detected, assigning an additional pathogenic  capacity to the strains, and very complex virulence  profiles. Serotyping assays proved that Sarda sheep  carried mainly non-O157 E. coli, including O91  serogroup, the role of these pathogroup in Public  Health must not be underestimated.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844398403\"\u003e\u003ch3\u003eDIRECT DETECTION OF VIRULENCE GENES AND MOLECULAR CHARACTERIZATION OF NON-O157 ISOLATES\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844398403","offer_id":39471315419229,"sku":"9783844398403","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1c410c56-c5ec-42ad-aa4f-31e101722455.jpg?v=1772866244","url":"https:\/\/shop.autorenwelt.de\/products\/shiga-like-toxin-producing-e-coli-in-sarda-slaughtered-sheep-von-gianluca-busia-und-rina-mazzette","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
