    摘要:

    目的 对死亡的恒河猴肺脏炎症组织采样进行病原菌分离、培养、鉴定及药敏试验,确诊病原菌及药物敏感性,指导疾病诊疗、预防和临床用药。 方法 解剖柜条件下解剖死亡猴,分别采集肉眼病变明显和正常肺组织,用灭菌接种环在肺切面部位采样,接种在SS琼脂培养基进行培养,培养时间24 h观察细菌生长情况, 进行生化鉴定和8种药敏试验。 结果 菌落呈白色或乳白色、圆形、湿润、不透明,进一步分离培养,经梅里埃微生物生化鉴定,确定该细菌为阴沟肠杆菌,ID:99. 9%,T:0. 71,ID 编码:35074753311;药敏试验表明该菌对氨苄西林,头孢呋辛中等敏感;对诺氟沙星、阿米卡星、庆大霉素、头孢曲松、头孢哌酮,头孢噻肟敏感。动物实验表明该分离菌对实验小鼠具有致病性。 结论 该恒河猴肺部感染阴沟肠杆菌,头孢哌酮,头孢噻肟等药物可作为治疗临床用药。

    Abstract:

    Objective To isolate, culture, identify, and analyze the drug sensitivity of pathogenic bacteria in inflamed lung tissue from a dead rhesus monkey, to determine the drug susceptibility of the bacteria, and to guide proper clinical application of such information. Methods The rhesus monkey was dissected under aseptic conditions. The lung was cut open and then insert focus of infection in the lung with inoculating loop to sampling and inoculating on plating medium. The presence of bacteria was observed, biochemical identification was performed, and eight kinds of antibiotic susceptibility test were carried out. Results Bacterial colonies on SS agar medium were white or ivory white, round,moist, and opaque. After the biochemical identification, the bacterium was identified as Enterobacter cloacae (ID: 99. 9%, T: 0. 71, ID number: 35074753311). The drug sensitivity test showed that the susceptibility of Enterobacter cloacae to eight antimicrobial agents was as follows: ampicillin and cefuroxime, intermediate sensitivity; and norfloxacin, amikacin, gentamicin, cefatriaxone, cefoperazone, and cefotaxime, saitivity. The Enterobacter cloacae isolated from rhesus monkey also showed a high risk to Kunming mice. Conclusions We conclude that the rhesus monkey lung was infected with Enterobacter cloacae. Cefoperazone and cefotaxime can be used clinically to treat cases like this in rhesus monkey.
