title: Partial sequence of the rRNA operon of Pneumocystis carinii isolates from Puerto Rico.
abstract: Several reports indicate geographic variation of isolates of Pneumocystis carinii hominis. We have sequenced the internal transcribed spacer (ITS) region and large subunit Group I intron of rRNA genes from P. carinii DNA obtained from two patients from Puerto Rico. Both can be subclassified as Type II, according to the sequence of the ITS region. A system capable of identifying individual isolates will be an essential tool for epidemiological studies of the organism. The amplification of DNA from fixed tissues may facilitate the processing of a large number of samples.
