 A change in the ICNafp now recognizes the validity of the 1976 publication, making the 1999 proposal redundant, and cites "Pneumocystis" and "P. jiroveci" as examples of the change in ICN Article 45, Ex 7.The name "P. jiroveci" is typified (both lectotypified and epitypified) by samples from human autopsies dating from the 1960s.The term PCP, which was widely used by practitioners and patients, has been retained for convenience, with the rationale that it now stands for the more general Pneumocystis pneumonia rather than Pneumocystis carinii pneumonia.
