An investigation was carried out to determine the prevalence and antibiotic resistance of Salmonella serotypes at South Korean duck farms. A total of 7119 samples collected from 72 duck farms in five provinces were examined from 2011 to 2012. The overall prevalence of Salmonella serotypes was 43.4% (69/159) in duck flocks from 65.2% (47/72) of the duck farms. Eighty-five strains were isolated from 69 duck flocks. Three serotypes of Salmonella enterica were identified such as S. Typhimurium (39/85), S. Enteritidis (44/85), and S. London (2/85). The prevalence of Salmonella infection decreased significantly in 3-week-old ducks compared to that in 1-week-old ducks (P<0.05). All isolates except one were resistant to at least one antimicrobial and 27% of the isolates were resistant to 5-16 antimicrobials. Our findings provide baseline information on the degree of Salmonella infection and distribution of Salmonella serotypes in ducks and indicate that ducks should be considered an important source of foodborne pathogens.
一项针对韩国养鸭场沙门氏菌血清型的流行情况和抗生素耐药性的调查。2011 年至 2012 年，从五个省的 72 个养鸭场采集了 7119 个样本进行检查。从 72 个养鸭场的 65.2%（47/72）鸭群中，沙门氏菌血清型的总流行率为 43.4%（69/159）。从 69 个鸭群中分离出 85 株菌。鉴定出三种血清型的沙门氏菌，分别为鼠伤寒沙门氏菌（39/85）、肠炎沙门氏菌（44/85）和伦敦沙门氏菌（2/85）。与 1 周龄鸭相比，3 周龄鸭的沙门氏菌感染率显著下降（P<0.05）。除一株外，所有分离株均至少对一种抗菌药物耐药，27%的分离株对 5-16 种抗菌药物耐药。本研究结果为沙门氏菌感染程度和鸭中沙门氏菌血清型的分布提供了基线信息，并表明鸭应被视为食源性致病菌的重要来源。
