Serological Monitoring of Livestock Brucellosis in Hezhou City,Guangxi Zhuang Autonomous Region from 2019 to 2022
摘要
Abstract
In order to investigate the prevalence of livestock brucellosis in Hezhou City,Guangxi Zhuang Autonomous Region,serological monitoring of brucellosis was conducted on some intensive farms with pigs,cattle or sheep from 2019 to 2022,and the positive farms were epidemiologically investigated.The results showed that the population positive rates were 0,1.00%(2/200)and 3.86%(17/440)for pigs,cattle and sheep,respectively;and the individual ones were 0,0.03%(8/24 030)and 0.88%(156/17 732),respectively.No positive case of bovine brucellosis was detected from 2019 to 2021,except in 2022 when brucellosis was detected with a low prevalence rate;positive cases of sheep brucellosis reached a minor peak in 2021,but decreased slightly in 2022.Sheep brucellosis was mainly caused by trade,movement of breeding rams or mixed feeding.For the positive farms where the population was not killed as a whole,the initial and secondary reinfection rates were 33.33%and 50.00%,respectively.In conclusion,brucellosis was prevalent in pig population in Hezhou City at lower risk,mainly in cattle and sheep,especially posing a risk of reinfection in the farms/populations where the whole population was not killed as a whole.It was thus recommended to push forward the construction of purification farms against brucellosis in cattle and sheep,adhere to the strategies of monitoring and stamping out whole population where any positive case was found,and to strengthen the supervision of movement quarantine and bio-safety management to prevent and control any occurrence or spread of brucellosis.关键词
