Transmission electron micrograph (TEM) of a section of lung tissue from a person suffering from Acquired Immune Deficiency Syndrome (AIDS),showing the presence of the parasitic protozoan,Pneumocystis carinii (appearing as roughly circular or crescent-shaped bodies). Pneumonia caused by Pneumocystis carinii is one of several,so-called opportunistic infections that persons infected with the AIDS virus may succumb to. The AIDS virus (an RNA-containing retrovirus) somehow destroys the T4 "helper" lymphocytes that are an essential factor in the body's response to infection. Magnification: X 6000 at 6x6 size | |
