摘要:

目的 通过回顾分析2017—2023年四川省实验动物寄生虫、微生物质量抽检结果,为进一步加强四川省实验动物管理提供参考。 方法 四川省共有实验动物生产单位31家,实验动物主要有小鼠、大鼠、豚鼠、兔、犬、猴、猪7种。按照现行国家和地方的实验动物等级相关标准,对四川省具有实验动物生产资质的单位进行抽样检测并出具检测报告,分析2017—2023年四川省内各种实验动物的质量检测结果。 结果 2017—2023年,除2018年外,每年进行一次实验动物质量抽检。小鼠:2017年检出蠕虫、鞭毛虫、沙门菌、小鼠肝炎病毒抗体和小鼠肺炎病毒抗体阳性,合格率仅为42.9%;2019年检出金黄色葡萄球菌和肺炎克雷白杆菌阳性,合格率为86.7%;2021年检出仙台病毒抗体阳性,合格率为85.7%;2020年、2022年和2023年合格率为100%。大鼠:2017年检出蠕虫、支原体抗体、金黄色葡萄球菌、仙台病毒抗体、小鼠肺炎病毒抗体、大鼠细小病毒RV株抗体、大鼠细小病毒H-1株抗体和大鼠冠状病毒抗体阳性,合格率为40.0%;2019年检出支原体抗体、金黄色葡萄球菌和肺炎克雷白杆菌阳性,合格率为35.0%;2020年未检出阳性指标;2021年检出仙台病毒抗体、大鼠细小病毒RV株抗体阳性,合格率为50.0%;2022年检出大鼠细小病毒RV株抗体阳性,合格率为87.5%;2023年检出嗜肺巴斯德杆菌和肺炎克雷白杆菌阳性,合格率为85.7%。犬:2017年、2019年检出狂犬病毒抗体和犬瘟热病毒抗体效价未达标,合格率分别为33.3%和20.0%;2020年和2022年合格率均为100%。普通级豚鼠:2019年检出弓形虫抗体阳性,合格率为80.0%;其余各抽检年份的合格率均为100%。猴:2019年检出弓形虫抗体、猕猴疱疹病毒I型(B病毒)抗体阳性,合格率为87.5%;2020年、2022年均有猕猴疱疹病毒I型抗体阳性检出,合格率分别为93.3%和97.5%;2021年和2023年合格率均为100%。清洁级豚鼠、兔和猪:各年抽检合格率均为100%。 结论 四川省实验动物寄生虫和微生物质量尚存在问题。监督抽检能帮助及时发现这些问题,是确保实验动物质量的重要手段。抽检结果可为促进四川省实验动物产业健康发展提供数据支持。

Abstract:

Objective To provide reference for further strengthening the management of laboratory animals in Sichuan Province by reviewing and analyzing the results of parasitic and microbial quality inspections of laboratory animals from 2017 to 2023. Methods Sichuan Province has 31 licensed laboratory animal production units, with the main species including mice, rats, guinea pigs, rabbits, dogs, monkeys, and pigs. Sampling inspections and reports were conducted for units with laboratory animal production qualifications in accordance with current national and local standards for laboratory animal classification. The quality inspection results for various laboratory animals in Sichuan Province from 2017 to 2023 were analyzed. Results With the exception of 2018, annual quality inspections of laboratory animals were conducted every year between 2017 and 2023. Mice: In 2017, positive results for helminths, flagellates, Salmonella, murine hepatitis virus antibodies, and murine pneumonia virus antibodies were detected, with a pass rate of only 42.9%. In 2019, Staphylococcus aureus and Klebsiella pneumoniae were detected, with a pass rate of 86.7%. In 2021, Sendai virus antibodies were detected, yielding a pass rate of 85.7%.The pass rate in 2020, 2022, and 2023 was 100%. Rats: In 2017, positive results were found for helminths, mycoplasma antibodies, Staphylococcus aureus, Sendai virus antibodies, murine pneumonia virus antibodies, rat parvovirus RV strain antibodies, rat parvovirus (H-1) strain antibodies, and rat coronavirus antibodies, with a pass rate of 40.0%. In 2019, mycoplasma antibodies, Staphylococcus aureus and Klebsiella pneumoniae were detected, with a pass rate of 35.0%. No positive indicators were detected in 2020. In 2021, Sendai virus antibodies and rat parvovirus RV strain antibodies were detected, with a pass rate of 50.0%. In 2022, positive results for rat parvovirus RV strain antibodies were found, yielding a pass rate of 87.5%. In 2023, Pasteurella pneumotropica and Klebsiella pneumoniae were detected, with a pass rate of 85.7%. Dogs: In 2017 and 2019, the antibody titers for rabies virus and canine distemper virus were below the required standard, with pass rates of 33.3% and 20.0%, respectively. In 2020 and 2022, the pass rate was 100%. Guinea pigs (general grade): In 2019, positive results for Toxoplasma antibodies were detected, with a pass rate of 80.0%. In all other years, the pass rate was 100%. Monkeys: In 2019, positive results for Toxoplasma gondii and rhesus herpesvirus type I antibodies were found, with a pass rate of 87.5%.In 2020 and 2022, rhesus herpesvirus type I antibodies were positively detected, yielding pass rates of 93.3% and 97.5%, respectively. The pass rates in 2021 and 2023 were 100%. Clean guinea pigs, rabbits and pigs all passed the inspection each year. Conclusion Issues related to the parasitic and microbial quality of laboratory animals persist in Sichuan Province. Supervision and sampling inspections have proven to be effective in identifying these issues promptly, serving as a critical measure to ensure the quality of laboratory animals. The results of these inspections offer valuable data to support the healthy development of the laboratory animal industry in Sichuan Province.
