ANTIBODIES TO AKABANE VIRUS IN AUSTRALIA

SUMMARY Neutralising antibody to Akabane virus was shown to develop in cattle in northern Australia throughout the year and also on the east coast of New South Wales in the summer during 1975/1976. Other species found to have antibody to Akabane virus were buffaloes, horses, camels and sheep, but no antibody was found in domestic chickens, ducks, wallabies or man. The biting midge Culicoides brevitarsis has been detected in all the major areas where antibody was demonstrated in this study.     

A SURVEY OF ANTIBODY TO AINO VIRUS IN CATTLE AND OTHER SPECIES IN AUSTRALIA

SUMMARY A serological survey of healthy cattle in Australia showed that antibodies to Aino virus were present in serums from cattle in northern Australia and down the east coast as far as central New South Wales in 1975, 1976 and 1977, but occurred with a lower frequency than antibodies to Akabane virus. in contrast to the findings with Akabane virus, no neutralising antibodies to Aino virus were detected in serums from camels, dogs or horses. Antibodies to both viruses were detected in buffaloes and sheep, but not in humans or any of the Australian indigenous species so far tested. All positive serums originated from within the known range of Culicoides brevitarsis.     

近年来上海地区病死猪主要病毒病感染状况调查

为掌握动物疫情动态,消除疫情隐患,及时了解上海及周边地区猪主要病毒病的流行趋势,采用实时荧光RT-PCR方法对2006～2009年上海地区规模猪场和养猪散户送检的门诊收集的临床病例样本进行主要病毒病的病原学检测,主要包括猪瘟病毒（Classicalswine fever virus,CSFV）、猪繁殖与呼吸综合征病毒（Porcinereproductive and respiratory syndrome virus,PRRSV）、猪伪狂犬病毒（Pseudorabiesvirus,PRV）和猪圆环病毒2型（Porcinecircovirustype2,PCV2）,通过,临床检测,结果表明这些病原在上海及周边地区是普遍存在的,给猪病防疫带来了重大隐患。
