Pneumocystis colonization in older adults and diagnostic yield of single versus paired noninvasive respiratory sampling

Sergio L Vargas et al. Clin Infect Dis. .

Abstract

The presence of Pneumocystis was assessed in oropharyngeal wash specimens from 110 adults (median age, 76 years; age range, 69-95 years), 66 of whom had a paired nasal swab specimen. Pneumocystis jirovecii DNA was detected in 12.8% of oropharyngeal wash specimens, and the frequency increased to 21.5% in paired specimens. Pneumocystis colonization is prevalent in older adults. Double noninvasive sampling increases the diagnostic yield.
