Disease/effect: Note the difference between Pneumocystis pneumonia and Pneumococcus pneumonia. The latter is caused by the bacterium Streptococcus pneumoniae.
Hosts/materialDisease/effectClinical picture or result
RatPneumocystosis (Pneumocystis-pneumonia, PCP).Weight loss, rough fur or dry skin and a curvy posture. The organism can cause severe, often fatal pneumonia in immunocompromised host animals.

The strain B8 originates from a rat.

Taxonomy/phylogeny: Previously, both the organism that causes Pneumocystis pneumonia (PCP) in humans and in rats was called Pneumocystis carinii. Another name for the species that causes PCP in humans has been suggested, namely Pneumocystis jirovecii. However, this name has not been accepted by all researchers and since there are small differences between these two taxa, it has been suggested that subspecies or special form (forma specialis) should be used to differentiate between different taxa. At AgriMyc, we have chosen to use subspecies.
Comment:It has long been thought that Pneumocystis carinii was a protozoan (heterotrophic protist), but by using molecular genetic methods it has been shown that this organism is a fungus belonging to the phylum Ascomycota.
