我国婴幼儿食品致病细菌的耐药性监测

本实验从95份婴儿食品中,检出共29株菌株,包括8株阴沟肠杆菌、5株非脱羧勒克氏菌、2株少动鞘氨醇单胞菌、3株屎肠球菌、2株鹑鸡肠球菌、3株阪崎杆菌、2株泛菌属、2株产酸克雷伯氏菌、1株植生拉乌尔菌及1株解鸟氨酸拉乌尔菌.并对这29株菌株进行了耐药性监测,发现其中只有泛菌属对18种抗生素全敏感,其它9类菌株均产生了不同程度的耐药,同一菌株对不同的药物的抗药性不同,不同菌株对同一药物的抗药性也不同,并且普遍出现多重耐药现象.耐药率12.5%～100%,其中耐药率最高的是氨苄西林(AM).

The drug resistant investigation of pathogenic bacteria for Chinese infant food

In this investigation,29 strains of bacteria were detected from 95 samples of infant food,including 8 strains of E.cloacae,5 strains of Leclercia adecarboxylata,2 strains of Sphingomonas paucimobilis,3 strains of Enterococcus faecium,2 strains of Enterococcus gallinarum,3 strains of E.sakazakii,2 strains of Pantoea dispersa,2 strains of Klebsiella oxytoca,1 strain of Raoulrella planticola,1 strain of Raoulrella ornithinolytica,as well as 1 strain of ornithine Raoul. Resistance rate ranges from 12.5% to 100%,the highest rate of drug resistance is ampicillin (AM). The results indicate that only the strain of Pantoea dispersa is sensitive to 18 types of antibiotic,other strains have resistance to antibiotics in various degrees. Besides,the same strain had different resistance to antibiotics and different strains have different resistance to one antibiotic. More remarkably,the strains even have multiple resistances to antibiotics.
