title: False-positive PCR detection of Tropheryma whipplei in cerebrospinal fluid and biopsy samples from a child with chronic lymphocytic meningitis.
abstract: We report the case of a teenager with chronic lymphocytic meningitis for whom Tropheryma whipplei 16S rRNA PCR results were positive in two cerebrospinal fluid samples and one duodenal biopsy specimen. PCR targeting another specific sequence of Tropheryma whipplei and sequencing of the initially amplified 16S rRNA fragment did not confirm the results.
