Species/Subspecies:

Pneumocyctis carinii subsp. carinii

Category:

Animal pathogen

Etymology:

Genus name: lung sac .
Species epithet: named after one (or more) naturalist(s) named Carin.
Subspecies epithet: see Species epithet.

Significance:

This organism is of some importance in veterinary medicine, but it mainly affects animals with weakened immune systems.
[Of minor importance]

Taxonomy:

Phylum	Class	Order	Family	Genus
Ascomycota	Pneumocystidomycetes	Pneumocystidales	Pneumocystidaceae	Pneumocystis

Macromorphology (smell):

Note the difference between Pneumocystis pneumonia and Pneumococcus pneumonia. The latter is caused by the bacterium Streptococcus pneumoniae.

Genome Sequence:

There is no whole genome sequence reported.

18S rRNA Seq:

ACC-No GenBank	Strain/Isolate	Number of NT
XR_001936350		1805

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.
