目的:分析茂名市食源性沙门菌菌型分布和耐药性,为防治沙门菌引起食源性疾病提供科学依据。方法:对27株分离于食品、腹泻病例和食物中毒的沙门菌进行血清学分型和药物试验。结果:27株沙门菌分属6个血清群11个血清型,以德尔卑沙门菌占主要优势,占29.63%,其次是鼠伤寒沙门菌和伦敦沙门菌,分别占14.81%;对加替沙星和亚胺硫霉素(泰能)100%敏感,对罗米沙星、氧哌嗪青霉素/泰舒和头孢他定的敏感率均为96.30%,对复方新诺明、氨苄青霉素、阿莫西林/棒酸和丁胺卡那霉素,耐药率分别为96.30%、92.59%、62.96%和62.96%,对头孢西丁等13种其他抗生素有不同程度耐药。结论:茂名市食源性沙门菌血清型主要是德尔卑沙门菌、鼠伤寒沙门菌和伦敦沙门菌;加替沙星和亚胺硫霉素(泰能)为首选治疗药物。
Objective: To analyze the distribution and drug resistance of food-borne salmonella in Maoming and to provide a scientific basis for preventing food-borne diseases caused by Salmonella. Methods: Serological typing and drug tests were performed on 27 strains of Salmonella isolated from food, diarrhea cases and food poisoning. Results: 27 strains of Salmonella belonged to 6 serogroups and 11 serotypes, accounting for 29.63% of the total, accounting for 14.61%, followed by Salmonella typhimurium and Salmonella salmonella, accounting for 14.81% Star and imipenem (Thai can) 100% sensitive to romyomycin, piperacillin / taishu and ceftazidime sensitivity rates were 96.30%, the compound cotrimoxazole, ampicillin, A Moxillin / clavulanic acid and amikacin, the drug resistance rates were 96.30%, 92.59%, 62.96% and 62.96%, respectively. Thirteen other antibiotics such as cefoxitin were resistant to some extent. Conclusion: The main serotypes of food-borne Salmonella in Maoming are Salmonella delphi, Salmonella typhimurium and Salmonella typhimurium. Gatifloxacin and imipenem are the preferred treatment drugs.
