Molecular epidemiology of Pneumocystis carinii pneumonia.
Although reactivation of latent infections has long been considered the primary explanation for PCP in immunosuppressed patients, over the years a steady flow of reports has described clusters of PCP cases (2). In addition, recent studies have suggested that the duration of latency is very limited, i.e., usually less than 1 year (3,4). Still other studies have demonstrated genetic variation in ...
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...
متن کاملPneumocystis carinii.
Although Giemsa staining has been routinely used for the detection of trophozoites and intracystic bodies in smears of bronchoalveolar lavage fluid (BAL) from patients with Pneumocystis cariniipneumonia, it does not normally stain the cyst wall. For detection ofthe cysts other stains such as toluidine Blue 'O' and methenamine silver must be used as well. Sulphation of smears before staining wit...
متن کاملBasic biology of Pneumocystis carinii: a mini review.
Basic aspects of cell biology of Pneumocystis carinii are reviewed with major emphasis on its life cycle and the structural organization of the trophozoites and cyst forms. Initially considered as a protozoan it is now established that Pneumocystis belongs to the Fungi Kingdom. Its life cycle includes two basic forms: (a) trophozoites, which are haploid cells that divide by binary fission and m...
متن کاملPreliminary results of Pneumocystis carinii strain differentiation by using molecular biology.
The mode of Pneumocystis carinii transmission is controversial. Recent studies point to exogenous inoculation rather than reactivation, and person-to-person transmission has also been suggested. Comparison of nucleotide sequences of the large-subunit mitochondrial rRNA gene of P. carinii from human immunodeficiency virus-seropositive patients showed strain differences.
