The Fascinating Echinocandin-Treated Mouse Model of Pneumocystis murina To Understand Pneumocystis jirovecii

Antibody Response to Pneumocystis jirovecii

We conducted a prospective pilot study of the serologic responses to overlapping recombinant fragments of the Pneumocystis jirovecii major surface glycoprotein (Msg) in HIV-infected patients with pneumonia due to P. jirovecii and other causes. Similar baseline geometric mean antibody levels to the fragments measured by an ELISA were found in both groups. Serum antibodies to MsgC in P. jirovecii...

Etymologia: Pneumocystis jirovecii

Spelling Pneumocystis jirovecii

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 ...

Pneumocystis jirovecii Pneumonia

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...

Airborne spread of Pneumocystis jirovecii.

In this issue of the journal, Choukri et al [1] state that their study provides the first quantitative data on the spread of Pneumocystis jirovecii in exhaled air from infected patients. There are additional data in prior studies using air samples collected in rooms of patients diagnosed as having P. jirovecii showing that not only could the organisms be detected but also their types correlated...
