Cbv. Christensen et al., PNEUMOCYSTIS-CARINII FROM PIGS AND HUMANS ARE ANTIGENICALLY DISTINCT, Journal of medical and veterinary mycology, 34(6), 1996, pp. 431-433
The antigens of Pneumocystis carinii cysts isolated from pigs and huma
ns were compared by the Western immunoblotting technique. Convalescent
pig serum reacted with two antigens (approximately 78 kDa and 32.5 kD
a) of porcine P. carinii cysts, whereas convalescent serum from humans
did not react with porcine P. carinii cyst antigens. The results indi
cate that porcine and human P. carinii cysts are antigenically distinc
t.
