Genetic variation in Pneumocystis carinii isolates from different geographic regions: implications for transmission.
To study transmission patterns of Pneumocystis carinii pneumonia (PCP) in persons with AIDS, we evaluated P. carinii isolates from patients in five U.S. cities for variation at two independent genetic loci, the mitochondrial large subunit rRNA and dihydropteroate synthase. Fourteen unique multilocus genotypes were observed in 191 isolates that were examined at both loci. Mixed infections, accou...
متن کاملTransmission of Pneumocystis carinii from patients to hospital staff.
BACKGROUND An extrahuman reservoir of human pathogenic Pneumocystis carinii remains unknown. Host to host transmission has been described in animal studies and in cluster cases among immunodeficient patients. P carinii DNA has recently been detected in air filters from inpatient and outpatient rooms in departments of infectious diseases managing patients with P carinii pneumonia (PCP), suggesti...
متن کاملGenetic heterogeneity of Pneumocystis carinii from rats of several regions and strains.
Pneumocystis carinii is a major opportunistic pathogen which has been found in the lungs of a wide variety of mammalian host species, and the fact suggests the possibility of intraspecific variation. Until now, P. carinii from different mammalian species are differentiated as subspecies, and the rats are known to be infected by two subspecies. The present study investigated genetic heterogeneit...
متن کاملGrowth of Pneumocystis Carinii in Axenic Culture
SUMMARY In this research, which was done for two years, we investigated various liquid and solid media without feeder ceells, for the ability to support growth of P. carinii. Data obtained from counting the organisms nuclei showed that, addition of Cycloheximide, penicillin, & streptomycin to neopeptoneN-Acetyle Glucoseamine (N.P.G. medium) can provides growth requirements of organism in its...
