520			\|a Background Salmonella has been considered as one of the most important foodborne pathogens that threatened breeding industry and public health. To investigate the prevalence and characterization of Salmonella isolated from duck farms and a slaughterhouse in Shandong province, a total of 49 Salmonella strains were isolated from 2342 samples from four duck farms and one duck slaughterhouse in Jinan and Tai’an, Shandong province, China. Results Among the isolates, S. Enteritidis (20/49, 40.8%) and S. Anatum (10/49, 20.4%) were the most prevalent, and high resistance rates were detected for erythromycin (49/49, 100.0%) and nalidixic acid (47/49, 95.9%). Class I integrons were detected in 17 isolates (34.7%17/49), which contained gene cassettes aadA7 + aac3-Id(15/17) and aadA5 + dfrA17 (2/17). Eleven different kinds of resistance genes were detected while blaTEM(36/49, 73.5%) was the most prevalent, followed by sul2(14/49, 28.6%). Thirteen virulence genes were tested, and all of the strains carried invA, hilA and sipA. Multilocus sequence typing (MLST) results showed that seven sequence types (STs) were identified; ST11 was the most prevalent ST (20/49, 40.8%), followed by ST2441 (10/49, 20.4%). There was a strong correlation between STs and serovars. The results of pulsed field gel electrophoresis(PFGE) showed that 39 PFGE patterns were generated from 49 Salmonella strains. PFGE patterns were mostly diverse and revealed high similarity between the isolates from the same sampling sites. Conclusions The presence of Salmonella infections among duck farms revealed that ducks could also be potential reservoirs for Salmonella. The high resistance rates against commonly used antimicrobials suggested a need for more reasonable use of antimicrobials, as well as for investigating substitutes for antimicrobials.

To investigate the prevalence and characterization of Salmonella isolated from duck farms and a slaughterhouse in Shandong province, a total of 49 Salmonella strains were isolated from 2342 samples from four duck farms and one duck slaughterhouse in Jinan and Tai’an, Shandong province, China. Results Among the isolates, S. Enteritidis (20/49, 40.8%) and S. Anatum (10/49, 20.4%) were the most prevalent, and high resistance rates were detected for erythromycin (49/49, 100.0%) and nalidixic acid (47/49, 95.9%). Class I integrons were detected in 17 isolates (34.7%17/49), which contained gene cassettes aadA7 + aac3-Id(15/17) and aadA5 + dfrA17 (2/17). Eleven different kinds of resistance genes were detected while blaTEM(36/49, 73.5%) was the most prevalent, followed by sul2(14/49, 28.6%). Thirteen virulence genes were tested, and all of the strains carried invA, hilA and sipA. Multilocus sequence typing (MLST) results showed that seven sequence types (STs) were identified; ST11 was the most prevalent ST (20/49, 40.8%), followed by ST2441 (10/49, 20.4%). There was a strong correlation between STs and serovars. The results of pulsed field gel electrophoresis(PFGE) showed that 39 PFGE patterns were generated from 49 Salmonella strains. PFGE patterns were mostly diverse and revealed high similarity between the isolates from the same sampling sites. Conclusions The presence of Salmonella infections among duck farms revealed that ducks could also be potential reservoirs for Salmonella. The high resistance rates against commonly used antimicrobials suggested a need for more reasonable use of antimicrobials, as well as for investigating substitutes for antimicrobials.

abstract	Background Salmonella has been considered as one of the most important foodborne pathogens that threatened breeding industry and public health. To investigate the prevalence and characterization of Salmonella isolated from duck farms and a slaughterhouse in Shandong province, a total of 49 Salmonella strains were isolated from 2342 samples from four duck farms and one duck slaughterhouse in Jinan and Tai’an, Shandong province, China. Results Among the isolates, S. Enteritidis (20/49, 40.8%) and S. Anatum (10/49, 20.4%) were the most prevalent, and high resistance rates were detected for erythromycin (49/49, 100.0%) and nalidixic acid (47/49, 95.9%). Class I integrons were detected in 17 isolates (34.7%17/49), which contained gene cassettes aadA7 + aac3-Id(15/17) and aadA5 + dfrA17 (2/17). Eleven different kinds of resistance genes were detected while blaTEM(36/49, 73.5%) was the most prevalent, followed by sul2(14/49, 28.6%). Thirteen virulence genes were tested, and all of the strains carried invA, hilA and sipA. Multilocus sequence typing (MLST) results showed that seven sequence types (STs) were identified; ST11 was the most prevalent ST (20/49, 40.8%), followed by ST2441 (10/49, 20.4%). There was a strong correlation between STs and serovars. The results of pulsed field gel electrophoresis(PFGE) showed that 39 PFGE patterns were generated from 49 Salmonella strains. PFGE patterns were mostly diverse and revealed high similarity between the isolates from the same sampling sites. Conclusions The presence of Salmonella infections among duck farms revealed that ducks could also be potential reservoirs for Salmonella. The high resistance rates against commonly used antimicrobials suggested a need for more reasonable use of antimicrobials, as well as for investigating substitutes for antimicrobials. © The Author(s). 2019
