UNASSIGNED: Objective: To determine the serotypes and drug resistance profiles of Shiga toxin-producing @entity526 (STEC) in animal stools from the Weishan area in Shandong Province, China. To provide the basis for further study. Methods: Five hundred animal stool samples (from @entity1707 , @entity291 , @entity742 , @entity235 and birds) were collected from the Weishan area and STEC strains were isolated from these samples. Strains were serotyped by a serum agglutination test, and their drug resistance profiles were determined through antimicrobial sensitivity experiments. In this study, PCR was used to detect @entity803 resistance genes (tetA, tetB, tetC, tetD) and @entity8545 resistance genes (blaSHV-1, blaCTX-M, blaTEM). Results: Sixteen strains of STEC were isolated from animal stool samples. Thirteen strains were isolated from @entity1707 stool samples, two from @entity291 stool samples and one from a @entity742 stool sample. Two of the strains were identified as @entity526 O157:H7, and other 14 strains were non-O157 STEC of different serotypes. Antimicrobial sensitivity experiments showed that 15 of the strains were multidrug resistant. The rates of resistance were as follows: @entity802 (12/16 strains), @entity23174 (11/16), @entity206 and @entity207 (11/16), @entity3403 (9/16), @entity4580 (9/16), @entity803 (9/16), @entity2755 (8/16) and @entity3639 (8/16). Therefore, @entity802 showed the highest rate of resistance among the strains, followed by @entity206 and @entity207 , and @entity23174 . Resistance to @entity6944 or @entity2892 was not detected. In total, three types of drug resistance genes (tetA, tetB and tetC) were detected among the 16 strains. Conclusion: The results showed that STEC strains isolated from animals in the Weishan area were of a range of serotypes. The 16 strains of STEC isolated from animal stools in this area were resistant to a number of antibiotics, with many strains displaying multidrug resistance.
