Prevalence Investigation and Analysis of Pasteurella multocida in Beef Cattle and Tan Sheep in Ningxia Region
摘要
Abstract
In order to understand the prevalence of P.multocida in the main breeding areas of beef cattle and Tan sheep in Ningxia,this study collected a total of 382 nasal swabs from 24 large-scale farms in 8 counties/districts,including Tongxin county,Yanchi county,and Yuanzhou district.Pathogen isolation and molecular biology detection were used,and the Taqman real-time fluorescence quantitative PCR detection method was used for capsule serotyping analysis.The results showed that a total of 77 P.multocida strains were isolated and identified.The total positive rate was 20.2%(77/382),with positive rates ranging from 12.7%to 34.3%in various regions.Among them,the highest positive rate was 34.3%in Lingwu city and the lowest positive rate was 12.7%in Tongxin county.The typing results showed that there were 44(57%)strains of capsule serotype A,29(38%)strains of capsule serotype B,and 4(5%)strains of capsule serotype D.The incidence of P.multocida in beef cattle and Tan sheep was mainly concentrated between 3 and 8 month ages,with an infection rate of over 13%.This study provides a basis for the scientific prevention and control of P.multocida in beef cattle and Tan sheep in Ningxia.关键词
