德化县规模化猪场衣原体病血清学检测与分析

Serological detection and analysis of swine chlamydiosis in large-scale pig farms in Dehua county

为进一步了解德化县规模化猪场猪衣原体病的流行情况,采用间接血凝试验对2021-2022年德化县规模化猪场送检的猪群(公猪、母猪、后备母猪)血清样本进行衣原体病流行病学检测。检测结果显示2021年猪群衣原体感染率为27.3%,高于2022年的24.3%,2022年各猪群的衣原体感染率较2021年均有所下降。经过比较可知,猪群中母猪和公猪的衣原体感染率明显高于后备母猪。研究发现德化县规模化猪场每个季度均有猪群感染衣原体,呈流行趋势,尤其是母猪的感染率更高,由于衣原体病的危害严重,应采取综合防治措施控制该病流行。

In order to further understand the epidemic situation of pig chlamydiosis in large-scale pig farms in Dehua county,indirect hemagglutination test was used to detect the epidemiology of chlamydiosis in serum samples of pig herds(boars,sows,and reserve sows)submitted by large-scale pig farms in Dehua county from 2021-2022.The test results showed that the chlamydia infection rate in pig herds in 2021 was 27.3%,higher than 24.3%in 2022.The chlamydia infection rate in each pig herd in 2022 decreased compared to the average year of 2021.After comparison,it can be seen that the infection rate of chlamydia in sows and boars in pig herds is significantly higher than that in reserve sows.The study found that pigs in Dehua county's large-scale pig farms were infected with chlamydia in every quarter,showing an epidemic trend,especially the infection rate of sows was higher.Due to the serious harm of chlamydiosis,comprehensive control measures should be taken to control the epidemic of the disease.
