    摘要:

    目的调查国内实验恒河猴和食蟹猴中幽门螺杆菌和”猕猴螺杆菌”的感染情况。方法参考文献中的螺杆菌属16S rRNA和幽门螺杆菌16S rRNA的引物序列,和新设计的“猕猴螺杆菌”16S rRNA特异性引物,在人工养殖的45只成年恒河猴和90只成年食蟹猴粪便样本中,通过qPCR或常规PCR检测来初步调查这两种猕猴中两种螺杆菌的感染情况。结果在恒河猴中幽门螺杆菌和“猕猴螺杆菌”的感染率均为100%,在食蟹猴中幽门螺杆菌和”猕猴螺杆菌”的感染率分别为100%和98.9%。结论首次证实我国人工繁育饲养的恒河猴和食蟹猴普遍存在“猕猴螺杆菌”感染。幽门螺杆菌和”猕猴螺杆菌”几乎同时存在于所有人工繁育的实验猴个体中,可能会对这两种猕猴的健康以相关动物实验结果的准确性存在不利影响。

    Abstract:

    Objective Investigate the situation of Helicobacter pylori and “Helicobacter macacae” infection in purpose bredrhesus and cynomolgus monkeys in China. Method With the use of 16S rRNA specific primers for Helicobacter spp, and specific primers for 16S rRNA of Helicobacter pylori (HP) from published literatures, and new 16S rRNA specific primers designed for “Helicobacter macacae” (HM), we investigated the infecion status of these two Helicobacter spps in both of rhesus and cynomolgus monkeys by qPCR or conventional PCR on stool samples. Result All three primer sets for 16S rRNA exhibited excellent sensitivity and specificity. The infection rate of HP and HM were all 100% among 45 young adult rhesus monkeys. The infection rate of HP and HM in 90 young adult cynomolgus monkeys were 100% and 97.8% respectively. Conclusion Helicobacter pylori and “Helicobacter macacae” are present in almost every adult of rhesus and cynomolgus on purpose bred colonies, which may adversely affect the health of laboratory monkeys and the accuracy of related animal experiments.
