Objective To investigate the pathogen infections of Mongolian gerbils raised in a conventional facility,and to provide a basis for the establishment of local standards for pathogen detection in Mongolian gerbils. Methods A total of 16 species of bacteria,11 species of viruses and 8 species of parasites were detected in 30 gerbils raised in a conventional facility, according to the national standards of microorganism and parasite detection in mice and rats. Results Gerbils raised in this conventional facility were infected with lymphocytic choriomeningitis virus(a positive rate of 6. 7%), sendai virus(3. 3%), pneumonia virus of mice(100. 0%), reovirus type III(6. 7%), mouse encephalomyelitis virus(10. 0%), mycoplasma spp.(6. 7%), Tyzzer's organism(6. 7%)and Helicobacter spp. (56.7%),according to our antibody detection results. Meanwhile,the detected positive rate of Pasteurella pneumotropica was 3.3%,Staphylococcus aureus 10.0%,Escherichia coli O115 a,C,K(B)6.7%,Tritrichomonas muris 100.0% and flagellates 100.0%. Conclusions The results of our study provide a reference for the establishment of classification standards for gerbils according to their pathogen and parasite infections.%目的 对普通环境饲养的长爪沙鼠病原感染情况进行初步调查,为制定长爪沙鼠病原体检测地方标准提供依据.方法 参考小鼠、大鼠微生物和寄生虫检测方法,对普通环境饲养的30只长爪沙鼠进行16项细菌、11项病毒和8项寄生虫的检测.结果 饲养于普通环境的30只长爪沙鼠有淋巴细胞脉络丛脑膜炎病毒、仙台病毒、小鼠肺炎病毒、呼肠孤病毒III型、小鼠脑脊髓炎病毒、支原体、泰泽病原体、螺杆菌抗体检出,其检出率分别为6.7%、3.3%、100.0%、6.7%、10.0%、6.7%、6.7%和56.7%,同时检出嗜肺巴斯德杆菌感染率为3.3%,金黄色葡萄球菌感染率为10.0%,大肠埃希菌O115 a,C,K(B)感染率为6.7%,鼠三毛滴虫感染率为100.0%,鞭毛虫感染率为100.0%.结论 本研究为制定长爪沙鼠等级标准提供了参考数据.
