贵州省铜仁市碧江区犬狂犬病疫苗免疫抗体水平监测与分析
Monitoring and analysis of the level of rabies vaccine-induced antibodies in dogs in Bijiang District, Tongren City, Guizhou Province
目的 监测2023-2025年贵州省碧江区犬狂犬病疫苗免疫抗体水平,分析影响免疫效果的主要因素,为该病的有效防控提供依据。 方法 2023年3月-2025年10月,采集碧江区川硐街道、坝黄镇、灯塔街道及滑石乡等地已免疫狂犬病疫苗满3个月的犬只血清样本465份,采用ELISA法检测狂犬病病毒IgG抗体,并利用SPSS软件分析犬只年龄、活动区域及健康状况等因素对免疫效果的影响。 结果 394份血清样品检测为狂犬病毒抗体水平合格,平均合格率为84.73%,其中被调查的4个乡镇来源样品抗体合格率为79.53%~89.25%(P>0.05)。与2023年相比,2024年和2025年抗体合格率分别显著提高9.87、16.38百分点(P<0.05);不同年龄阶段犬只血清样品抗体合格率差异显著(P<0.05)。农村地区和乡镇地区来源样品抗体合格率差异不显著(P>0.05),分别为82.77%、86.64%;但有基础病史犬狂犬病疫苗抗体合格率显著低于无基础病史犬只(P<0.05),分别为74.78%、88.00%。 结论 碧江区犬狂犬病疫苗免疫抗体水平合格率较高,但需加强抗体水平监测,对于抗体不合格犬只进行加强免疫。
Objectives The level of rabies vaccine-induced antibodies in dogs in Bijiang District, Guizhou Province was monitored from 2023 to 2025 and the main factors affecting the efficacy of immune were analyzed to provide a scientific basis for the effective prevention and control of the disease. Methods 465 samples of serum were collected from dogs vaccinated against rabies for three months in Chuandong Street, Bahuang Town, Dengta Street, and Huashi Township in Bijiang District, Guizhou Province between March 2023 and October 2025. Enzyme-linked immunosorbent assay (ELISA) was used to detect the IgG antibody against rabies virus. SPSS software was used to analyze the effects of factors including the age of dog, living environment, and health status on the efficacy of immune. Results 394 samples of serum were detected for the level of antibody against rabies virus, with an average qualification rate of 84.73%. Among them, the qualification rate of antibodies in the samples from the 4 surveyed townships ranged from 79.53% to 89.25% (P>0.05). The qualification rate of antibody in 2024 and 2025 increased significantly by 9.87% and 16.38% (P<0.05) compared with that in 2023. There was a significant difference in the qualification rate of antibody in the samples of serum from dogs of different age groups (P<0.05). There was no significant difference in the qualification rate of antibody in the samples of serum from dogs in rural areas and township areas (P>0.05), which was 82.77% and 86.64%, respectively. However, the qualification rate of antibodies in the samples of serum from dogs with a basic medical history was significantly lower than that from dogs without a basic medical history (P<0.05), being 74.78% and 88.00%, respectively. Conclusions The qualification rate of antibodies against rabies virus in the samples of serum from dogs in Bijiang District, Guizhou Province is relatively high, but it is necessary to strengthen the monitoring of antibody level and enhance the vaccine immunization for dogs with unqualified rate of antibodies in the samples of serum.
