Epidemiological Investigation of Histophillus somni in Cows in Inner Mongolia Autonomous Region in 2022
摘要
Abstract
[Objective]To understand the infectious status of Histophillus somni(Hs)in cows in Inner Mongolia.[Method]65 dairy farms in 23 counties of 12 prefecture-level cities were investigated,including 20 large-scale dairy farms,21 small-scale dairy farms and 24 family farms.2 650 vaginal swabs were collected to detect Hs DNA by fluorescent PCR.[Result]The results showed that 11 cities had positive cases of Hs except for Wuhai City.Moreover,16 of 23 counties have been detected positive cases except for 7 negative counties and the proportion of positive counties was as high as 69.6%.The individual positive rates of large-scale dairy farms,small-scale dairy farms and family farms were 18.2%(182/1 000),22.9%(240/1 050)and 21.2%(127/600),respectively,and the positive rates of agricultural areas,pastoral areas and farming-pastoral areas were 15.6%(109/700),13.5%(135/1 000)and 32.1%(305/950),respectively.The average individual positive rate was 20.7%(549/2 650).[Conclusion]This study indicatd that Hs infection was very common in dairy farms in Inner Mongolia,prevention and control should be strengthened.关键词
