Serological titers to Pneumocystis carinii (Pc) and porcine reproductive and respiratory syndrome virus (PRRSV) were measured on a herd with epidemic Pc pneumonia (case herd) and two comparison herds, by an indirect fluorescent-antibody technique. In the case herd, the geometric mean titer (GMT) for Pc were 1:80 in pigs 1 week old, 1:10 in pigs 5 weeks old, and 1:80 to 1:190 in pigs over 6 weeks old. GMTs for PRRSV were > 1:145 in most of age groups over 7 weeks old. In comparison herds, Pc and PRRSV antibody titers were low in weanling pigs. The results clarified the kinetics of antibodies to Pc and concurrent infection of PRRSV in the case herd.
采用间接荧光抗体技术，对一个发生卡氏肺孢子虫（Pc）肺炎流行的猪群（病例猪群）以及两个对照猪群检测了抗卡氏肺孢子虫和猪繁殖与呼吸综合征病毒（PRRSV）的血清学滴度。在病例猪群中，1周龄仔猪抗Pc的几何平均滴度（GMT）为1:80，5周龄仔猪为1:10，6周龄以上仔猪为1:80至1:190。7周龄以上的大多数年龄组抗PRRSV的GMT均>1:145。在对照猪群中，断奶仔猪的抗Pc和抗PRRSV抗体滴度较低。结果阐明了病例猪群中抗Pc抗体的动态变化以及PRRSV的并发感染情况。
