Pneumocystis 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 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 کاملEndemic Pneumocystis Carinii Pneumonia
The entity of interstitial plasma cell pneumonia due to Pneumocystis carinii has received increasing attention during the past 10 years. Extensive studies and reviews concerning this problem, its epidemiology and pathogenesis (Ahvenainen, 1957; Bachmann, 1954; Cahalane, 1962; Jirovec, 1 960a and b; Muller and Vietor, 1957), its clinical course and picture (Berdnikoff, 1959; Dvorak and Jirovec, ...
متن کاملPneumocystis carinii karyotypes.
Pulsed-field gel electrophoresis techniques were used to examine the chromosomes of Pneumocystis carinii isolated from laboratory rats and two human subjects. P. carinii organisms isolated from each of four rat colonies and from two patients each produced a distinct band pattern, but in all cases the bands ranged in size from 300 to 700 kilobase pairs. P. carinii from three rat colonies produce...

A study is carried out in 8 infants with a diagnosis of Pneumocystis carinii pneumonia which was established through the study of histologic lung sections, and a microscopic study of protozoas. The following are some of the factors predisposing to this disease: prematurity, significant denutrition, primary immunodeficiencies, extended use of antibiotics, malignancies, and immunosuppressive trea...
