2012～2014年广西猪蓝耳病疫苗的免疫副反应分析

为了了解高致病性猪蓝耳病疫苗使用的免疫副反应情况,调查了广西部分地区2012 ～2014年使用8个疫苗生产厂家的猪蓝耳病疫苗的免疫副反应情况,并对不同年度、厂家,不同类型疫苗的副反应情况进行分析.结果表明,不同年度的副反应情况呈下降趋势;不同疫苗厂家生产的疫苗对应激反应有一定的差异;活苗和灭活苗的副反应差异显著.若要降低免疫副反应,防治人员的素质是重要的影响因素,应全面做好免疫前的准备工作,并根据猪群的健康状况调整免疫程序对降低免疫副反应有重要意义.

An investigation of 11 outbreaks of foot-and-mouth disease in villages in northern Thailand

The results of investigations of 11 outbreaks of foot-and-mouth disease in villages in northern Thailand are described. The causative virus was Asia in one in seven outbreaks, Type O in two outbreaks and unknown in two outbreaks. The most probable sources of the outbreaks were co-mingling of cattle and/or buffalo with livestock from an infected neighbouring village (four) and recent introductions of infected cattle from a public livestock market (two) while the probable source could not be determined in five outbreaks. Attack rates in cattle and buffalo ranged from 0.28% to 50.9% but no pigs became sick during any of the outbreaks. Most outbreaks lasted 4 weeks or less. Adult cattle and buffalo were at higher risk of becoming a case when compared with work cattle. Beef cattle were at higher risk than buffalo and adult cattle and buffalo were at higher risk than calves less than 1 year of age. There was significant clustering of cases within households. Serological investigations indicated that many unaffected animals were probably not exposed to virus during the outbreaks. We concluded that close contact between animals was the main method of spread and that differences in attack rates between animal classes reflected differences in animal management. We further concluded that simple quarantine of early cases during outbreaks is likely to be effective in reducing spread within and between villages.
