A serological survey for antibody to chicken anaemia agent (CAA) was carried out by indirect immunofluorescence. Antibody to CAA was widespread in broiler breeders and in parent and commercial layers in the UK. Antibody to CAA was also detected in five of 11 specific pathogen-free (SPF) chicken flocks tested; positive flocks included those being used for vaccine production or as commercial suppliers of SPF eggs. No antibody to CAA was detected in turkey or duck sera. A longitudinal survey of two broiler breeder flocks showed that maternal antibody to CAA persisted until about 3 weeks of age. Both flocks began to seroconvert to CAA at 8 to 9 weeks and the majority of birds had antibody at 18 to 24 weeks.
采用间接免疫荧光法对鸡贫血因子（CAA）抗体进行了血清学调查。在英国，CAA抗体在肉种鸡以及祖代和商品蛋鸡中广泛存在。在所检测的11个无特定病原体（SPF）鸡群中，有5个鸡群也检测到了CAA抗体；阳性鸡群包括那些用于疫苗生产或作为SPF种蛋商业供应商的鸡群。在火鸡或鸭血清中未检测到CAA抗体。对两个肉种鸡群进行的纵向调查表明，CAA母源抗体一直持续到约3周龄。两个鸡群均在8至9周龄时开始出现CAA血清转化，大多数鸡在18至24周龄时具有抗体。
