Rapporter deux cas cliniques de coinfections pulmonaires par Pneumocystis jirovecii et par Pseudomonas aeruginosa chez des patients vivant avec le VIH. Les deux patients étaient âgés respectivement de 32 ans et 46 ans. Un patient a été pris en charge à l'hôpital Yalgado Ouédraogo de Ouagadougou au Burkina Faso et l'autre a été pris en charge à l'hôpital Ténon de Paris, en France. Les deux souff...

Members of the genus Pneumocystis are microscopic yeast-like fungi that reside in the lungs of almost every mammal that has been evaluated for their presence. They grow extracellularly in the alveoli of mammals and are considered to be host obligate, as they cannot grow outside the lung on artificial media. Pneumocystis species (spp.) are typically restricted to the lungs, although extrapulmona...

To the Editor: Our 2002 article in Emerging Infectious Diseases about nomenclature changes for organisms in the genus Pneumocystis (1) has been widely cited and probably will remain a source for persons seeking information about this subject. Therefore, we need to correct an error in 1 of the species names presented in our article and in the 1999 article by Frenkel (2) on which our article was ...

To the Editor: Diversity of genotypes among Pneumocystis jirovecii (human-specifi c Pneumo-cystis species) isolates mainly involves internal transcribed spacer (ITS) loci (1). Type Eg, one of the most frequently detected ITS genotypes, has been found worldwide (2). The locus of dihydropteroate synthase (DHPS) is also of interest because DHPS is the target of sulfonamides, the main drugs used to...

Pneumocystis jirovecii is the causative agent of Pneumocystis pneumonia (PCP) in immunocompromised persons. Knowledge of the transmission and epidemiology of PCP is still incipient, and investigations on these subjects are based exclusively on applications of molecular typing techniques. The polymorphic internal transcribed spacers ITS1 and ITS2 in the ribosomal DNA operon, which in the P. jiro...

Pneumocystis jirovecii is an unusual ascomycetous fungus that can be detected in the lungs of healthy individuals. Transmission from human to human is one of its main characteristics in comparison with other fungi responsible for invasive infections. P. jirovecii is transmitted through the air between healthy individuals, who are considered to be the natural reservoir, at least transiently. In ...

conclusions the study indicated that the rate of p. jirovecii infection is similar to those reported from asian, indian and african countries. the similarity of the genetic pattern between iranian and indian isolates is probably due to their close geographical proximity. patients and methods we used two nested pcr and pcr-rflp assays to amplify mt lsu rrna and dhps genes in 126 samples obtained...

Pneumocystis jirovecii (formerly Pneumocystis carinii sp. f. hominis) is an unusual fungus exhibiting pulmonary tropism and a highly defined host specificity. It is generally regarded as an opportunistic microorganism causing severe and often fatal pneumonia in AIDS patients. However, with the currently rising number of patients receiving immunosuppressive therapies for malignancies, allogeneic...

METHODS Pneumocystis carinii pneumonia occasionally appears in immunodeficient patients. While several reports have shown that Pneumocystis carinii pneumonia occurred in the early phase of starting infliximab treatment in patients with Crohn's disease (CD), the present case suggests for the first time that an increased dosage of infliximab may also lead to pneumonia. RESULTS A 51-year-old mal...
