Pneumocystis carinii pneumonia was diagnosed by postmortem examination of a one-year-old Cavalier King Charles Spaniel with four-week history of dyspnea. Cytologic and histologic examination of lung tissues revealed numerous P. carinii trophozoites and cysts, and P. carinii specific DNA was detected by polymerase chain reaction. The dog showed hypogammagloblinemia and extremely low levels of se...

F Miller During the first 10 years of the AIDS pandemic the clinical features of the syndrome have been extensively reported. By January 1992 there had been 5451 cases of AIDS in the United Kingdom, 3391 patients having died, and 16 828 people were known to have antibodies to the human immunodeficiency virus (HIV), with the potential to progress to AIDS. Pneumocystis carinii pneumonia, despite ...

Pneumocystis species are opportunistic fungal pathogens that cause severe pneumonia in immunocompromised hosts. Recent evidence has suggested that unidentified proteases are involved in Pneumocystis life cycle regulation. Proteolytically active ADAM (named for "a disintegrin and metalloprotease") family molecules have been identified in some fungal organisms, such as Aspergillus fumigatus and S...

While Pneumocystis pneumonia (PcP) still impacts the AIDS patients, it has a growing importance in immunosuppressed HIV-negative patients. To determine the anti-Pneumocystis therapeutic efficacy of new compounds, animal and in vitro models have been developed. Indeed, well-designed mouse or rat experimental models of pneumocystosis can be used to describe the in vivo anti-Pneumocystis activity ...

Two new azasordarins, GW471552 and GW471558, were studied in vivo for treatment of Pneumocystis carinii pneumonia. In the Wistar rat spontaneous pneumonia model, both azasordarins significantly reduced the number of P. carinii cysts per gram of lung homogenate when administered at 1 mg/kg of body weight twice a day for 10 days. In a nude rat inoculation model, both compounds showed therapeutic ...

Fungi of the genus Pneumocystis are obligate parasites that colonize mammals' lungs and are host species specific. Pneumocystis jirovecii and Pneumocystis carinii infect, respectively, humans and rats. They can turn into opportunistic pathogens in immunosuppressed hosts, causing severe pneumonia. Their cell cycle is poorly known, mainly because of the absence of an established method of culture...

Pneumocysis jirovecii pneumonia (PJP) is a type of originating from the fungus Pneumocystis jiroveci and major cause serious in immunocompromised conditions. PJP typically appears as bilateral diffuse pulmonary infiltrates. Granulomatous an uncommon form pneumocystis infection, occurring only 3% to 5% patients. Calcification exceptional. We present 9-month-old boy affected by Severe Combined Im...
