Multilocus Sequence Typing of Pneumocystis jirovecii from Clinical Samples: How Several and Which Loci Ought to be UsedC ine Maitte,a Marion Leterrier,a,b Patrice Le Pape,a,b Michel Miegeville,a,b Florent Morioa,bLaboratoire de Parasitologie-Mycologie, CHU de Nantes, Nantes, Francea; D artement de Parasitologie et Mycologie M icale, Universitde Nantes, Nantes Atlantique Universit , EA 1155, IICiMed, Facultde Pharmacie, Nantes, FrancebPneumocystis jirovecii pneumonia (PCP) is an opportunistic infection with airborne transmission and remains a major cause of respiratory illness among immunocompromised people. In current years, several outbreaks of PCP, occurring largely in kidney transplant recipients, have been reported. Currently, multilocus sequence typing (MLST) performed on clinical samples is regarded to be the gold normal for epidemiological investigations of nosocomial clusters of PCP.Telithromycin However, until now, no MLST consensus scheme has emerged.G150 The aim of this study was to evaluate the discriminatory power of eight distinct loci previously made use of for the molecular typing of P.PMID:24957087 jirovecii (internal transcribed spacer 1 [ITS1], cytochrome b [CYB], mitochondrial rRNA gene [mt26S], significant subunit of the rRNA gene [26S], superoxide dismutase [SOD], -tubulin [ -TUB], dihydropteroate synthase [DHPS], and dihydrofolate reductase [DHFR]) utilizing a cohort of 33 epidemiologically unrelated individuals having respiratory samples that have been optimistic for P. jirovecii and who have been admitted to our hospital involving 2006 and 2011. Our outcomes highlight that the decision of loci for MLST is important, because the discriminatory energy with the strategy was highly variable from locus to locus. In all, the eight-locus-based scheme we utilised displayed a high discriminatory power (Hunter [H] index, 0.996). Primarily based on our findings, a easy and alternative MLST scheme relying on 3 loci only (mt26S, CYB, and SOD) delivers adequate discriminatory power (H-index, 0.987) to become used for preliminary investigations of nosocomial clusters of PCP. neumocystis jirovecii is an opportunistic fungal pathogen with humans as its only host (1, 2). P. jirovecii might be responsible for a severe pulmonary disease known as P. jirovecii pneumonia (PCP) in immunocompromised subjects, such as HIV-infected sufferers with CD4 cell counts of 200 cells/mm3, hematopoietic stem cell or solid organ transplant recipients, or these getting higher doses of corticosteroids for several months (three, four). In recent years, intense investigation has been conducted, leading to a superior und.
