Article Abstract: Pneumocystis carinii pneumonia is an opportunistic infection (that is, an infection that arises in the presence of an impaired immune system) frequently seen in AIDS patients. Mucormycosis & Rhizopus (AKA Zygomycosis) are opportunistic mycoses that are usually seen in diabetics (most often during ketoacidosis). SMITH ANDW. The organism is not commonly found in animals that have a functional immune system. The Gomori method of staining of Pneumocystis carinii in lung biopsy tissue or in fluid from percutaneous needle aspiration takes 3 hours to complete and requires experience and skill.

Pneumocystis carinii was examined in fresh preparations of infected rat lung homogenates and tissue culture supernatants by a variety of light microscope techniques, vital dyes, and histologic stains. The disease known as Pneumocystis carinii pneumonia (PCP) is a major cause of illness and death in persons with impaired immune systems. Pathogenicity and clinical significance. Pneumocystis carinii was originally thought to be a developmental stage in the life cycle of Trypanosoma when it was first observed in 1909. Opportunistic infection of pnemocystis carinii, measuring up to 6 um, usually concurrent infection by opportunistic bacteria, fungi, viruses especially CMV. As the acute pneumonitis subsides, children with mild-to-moderate disease who do not have malabsorption or diarrhea can be transitioned to oral treatment with the same total daily dose of TMP-SMX administered in 3 or 4 divided doses to complete a 21-day course (AII). 4 Pneumocystis jirovecii used to be called Pneumocystis carinii. The cyst forms are often described as “cup shaped” or like “ping pong balls” and are approximately half the size of red blood cells (which are typically 8 microns and a useful internal control for size). Symptomatic Pneumocystis pneumonia (PCP) is generally limited, however, to individuals with immune deficits. The taxonomy of the organism has been changed; Pneumocystis carinii now refers only to the Pneumocystis that infects rats, and P. carinii is a fungus and that infection in man is not a zoonosis.
