Pneumocystis carinii Infections in the United States

was reactive at the 1:8 and above level for 44% of the persons who had suspected and confirmed infections, for 7.3% of the healthy contacts, and for 1.4% of the general population. Results of tests with sera from people with measurable antibodies to other diseases and those on immunosuppressant therapy suggest that only titers of 1:20 and above are specific. At this level, tests with sera of 32...

Low Titer Pneumocystis jirovecii Infections: More than Just Colonization?

Non-pneumonia Pneumocystis jirovecii colonization is thought to occur frequently in immunocompetent individuals. The aim was to analyze if P. jirovecii low-titer detections have more impact than just colonization. From our total cohort of patients for which P. jirovecii testing by qPCR was requested, we selected exclusively those that were fully immunocompetent. Patients were defined as fully i...

Some observations on the serology of Pneumocystis carinii infections in the United States.

An indirect immunofluorescent (IF) test with antigen of partially cleaned Pneumocystis carinii cysts was evaluated for sensitivity and specificity. The test was reactive at the 1:8 and above level for 44% of the persons who had suspected and confirmed infections, for 7.3% of the healthy contacts, and for 1.4% of the general population. Results of tests with sera from people with measurable anti...

Detection of Pneumocystis carinii (jiroveci) from Iraqi Patients with Lower Respiratory Tract Infections

Background Pneumocystis carinii is one of the rare fungi which cause pneumonia in immunocompromised patients. It is important to detect the fungus from the clinical specimens of suspected patients by laboratory tests. Objective To identify Pneumocystis carinii from immunocompetent and immunocompromised patients with lower respiratory tract infections. Methods This study included 300 patients su...
