SO J Eukaryot Microbiol. 1993 Nov-Dec;40(6):821-6. Unique Identifier : AIDSLINE MED/94122711 AB Pneumocystis is a eukaryotic microbe that causes pneumocystosis, an AIDS-associated pneumonia. Pneumocystosis also occurs in many other mammalian species, and animal-derived organisms have been extensively utilized in Pneumocystis research. Pneumocystis from diverse hosts contain a large glycoprotein (gpA/MSG) on the surface. Antibodies elicited against gpA/MSG of Pneumocystis from humans sometimes cross-react with epitopes on proteins of similar size from Pneumocystis from other host species. Here we report the isolation and partial sequence of two presumptive gpA/MSG genes from human-derived Pneumocystis. The cloned human-derived Pneumocystis gpA/MSG genes and predicted peptides were different from those previously isolated from Pneumocystis from rats and ferrets. The genome of human-derived Pneumocystis contained multiple copies of sequences related to the two cloned gpA/MSG genes.
