Serum samples from 145 children with no known immunosuppressive illness were examined by indirect immunofluorescence for antibody to Pneumocystis carinii. Positive antibody titres (greater than or equal to 1:8 dilution) were found in 69 children (48%). Antibody could not be detected in the remaining children. Previous studies have shown that at least 75% of children have antibodies to P. carinii by the age of 4 years. This study shows a lower percentage of children with detectable antibody. This may be related to geographical variation of antigen or possibly to the widespread use of co-trimoxazole.
对145名无已知免疫抑制疾病的儿童血清样本进行间接免疫荧光检测,以检测卡氏肺孢子虫抗体。69名儿童(48%)的抗体滴度呈阳性(大于或等于1:8稀释度)。其余儿童未检测到抗体。先前的研究表明,至少75%的儿童在4岁时就有卡氏肺孢子虫抗体。本研究显示可检测到抗体的儿童比例较低。这可能与抗原的地理变异有关,也可能与复方新诺明的广泛使用有关。
