By definition, antigens are often defined as foreign substances produced by bacteria and viruses. In 2004, my research showing microphotographs of prostate cancer bacteria was posted on the website of the Journal of Independent Medical Research (www.joimr.org). ee Could bacteria in prostate collagen cause the biochemical elevation of the protein antigen detected by the PSA test?

The Fite stain is an "acid-fast" stain traditionally used for the detection of acid-fast tuberculosis-type bacteria. It is the essential staining technique required for the detection of cancer-associated bacteria. One of the Confirmation of prostate cancer bacteria To my knowledge, no tissue investigations into bacteria as a cause of prostate cancer were ever performed during the entire 20th century. However, over the past few years, several investigators have confirmed the presence of bacteria (particularly a species called Propionibacterium acnes) in prostate 18 *« NEXUS APRIL - MAY 2009 www.nexusmagazine.com
