Some yeasts are harmful to living things or utensils. For example, red yeast (Rhodotorula) grows on wet furniture such as shower curtains; Candida albicans (or Candida albicans) grows on the vaginal lining, etc. Humid human epithelial tissue.
Candida: can cause infections such as thrush and urethritis. Candida albicans in humans mainly appears on the mucous membranes of the mouth, intestines, urethra and other parts, and a small part lives on the surface of the skin. Under normal circumstances, Candida albicans exists as a yeast cell type and is not pathogenic; it is induced by some factors Under conditions such as immune deficiency, excessive use of antibiotics, etc., Candida albicans is transformed into a mycelial growth type, and multiplies, invades the patient's mucosal system, causing inflammation and disease. Women who take birth control pills in the third trimester of pregnancy are extremely susceptible to urethritis. One possible cause is an imbalance of hormones in the body.
Cryptococcus albidus (Cryptococcus albidus): is a budding yeast that is generally harmless to humans. But in people with immune system deficiency, it is possible to infect the patient and cause a disease called cryptococcosis (cryptococcosis). In addition, there is a case showing that a patient undergoing immunosuppressive therapy was infected with Cryptococcus albicans in the lungs, resulting in acute respiratory distress syndrome (ARDS).
Saccharomyces sereviciae (Saccharomyces sereviciae): It is generally not considered to be a conditional pathogen, but there are also a few reports showing that Saccharomyces sereviciae has pathogenic ability.
