''Schizosacharomyces pombe'' is a yeast first isolated from East African millet beer (''pombe'' is the Swahili word for beer).  However, it is most important as a laboratory experimental organism for the investigation of cell biology.  Sir Paul Nurse won the 2001 Nobel Prize for Physiology and Medicine for his discoveries of how the cell division cycle is regulated in ''S. pombe''. <ref> http://nobelprize.org/nobel_prizes/medicine/laureates/2001/ </ref>

''Candida albicans'' is a common [[commensal]] yeast which lives on human skin and in the gut.  About 50% of people carry it, with no noticeable effect.  It is most well known as the cause of thrush, although less frequently it can cause nasty oral infections.  In severely immunocompromised patients it can spread through the body and invade vital organs, with a high mortality rate. <ref> http://www.healthscout.com/ency/68/312/main.html </ref>
