Resumo: | The Pneumocystis genus is comprised of pathogens dwelling in the lungs of terrestrial, aerial, and aquatic mammals. Occasionally they induce severe pneumonitis, particularly in hosts with severe impairment of the immune system and progressively may fill pulmonary alveolar cavities causing respiratory failure. Molecular genetic studies revealed that Pneumocystis gene sequences present a marked divergence with the host species concerned. In the present study, the genetic diversity of Pneumocystis obtained from lungs of swines was examined by analyzing mitochondrial large subunit (mtLSU) and small subunit (mtSSU) rRNA sequences. The samples were obtained from two slaughterhouses located in two Brazilian states. Phylogenetic analysis demonstrated that genetic groupings within Pneumocystis organisms were in accordance with those of the corresponding hosts and that two clusters were formed. In conclusion, these data show that there are genetically distinct porcine Pneumocystis genotypes with at least two separate clusters in Brazil.
