To understand the infection of Salmonella (S.) in patients with diarrhea and outbreaks caused by Salmonella to identify the serotypes, resistance to antibiotics and PFGE types of the strains from the surveillance program in Guangdong province.
S. strains from patients with diarrhea were detected, and all the positive strains collected in routine and outbreak surveillance programs, were tested by serum agglutination, antibiotic susceptibility and PFGE.
71 S. strains were isolated from 1922 stool samples in 2008, with positive rate as 3.7%. 85 S. strains were isolated from 2110 stool samples in 2009, with positive rate as 4.0%. All the 156 strains were divided into 37 serotypes, with S. serotype typhimurium and enteritidis as the most common serotypes. 10 incidents of food poisoning were detected, of which 4 were caused by enteritidis and 3 by typhimurium. A suspected outbreak by enteritidis was discovered and under epidemiological investigation. The findings indicated that 2 of the 4 patients from this outbreak were infected with identical enteritidis isolates. 80% of the 229 isolates were found susceptible to cephalosporins and quinolone and 59.3% of them were multiresistant to the antibiotics.
S. enteritidis and S. typhimurium were the most common serotypes that caused infectious diarrhoea and food poisoning in Guangdong province.
了解腹泻患者沙门氏菌感染情况及沙门氏菌引起的疫情，以确定广东省监测项目中菌株的血清型、抗生素耐药性及脉冲场凝胶电泳（PFGE）类型。
对腹泻患者的沙门氏菌菌株进行检测，对常规监测和疫情监测项目中收集的所有阳性菌株进行血清凝集试验、抗生素敏感性试验及PFGE检测。
2008年从1922份粪便样本中分离出71株沙门氏菌，阳性率为3.7%。2009年从2110份粪便样本中分离出85株沙门氏菌，阳性率为4.0%。156株菌株共分为37个血清型，鼠伤寒沙门氏菌血清型和肠炎沙门氏菌血清型最为常见。检测到10起食物中毒事件，其中4起由肠炎沙门氏菌引起，3起由鼠伤寒沙门氏菌引起。发现一起疑似肠炎沙门氏菌疫情并正在进行流行病学调查。结果表明，此次疫情中4名患者中的2名感染了相同的肠炎沙门氏菌分离株。229株分离株中80%对头孢菌素和喹诺酮敏感，59.3%对多种抗生素耐药。
肠炎沙门氏菌和鼠伤寒沙门氏菌是广东省引起感染性腹泻和食物中毒最常见的血清型。
