Forty-six (89%) of 52 HIV-infected men were seropositive for CMV by combined assay for IgG/IgM; two more (48…

Detection and identification of bacterial DNA in semen

Objective: To detect and identify bacteria in semen by sequencing polymerase chain reaction (PCR)–amplified ribosomal RNA gene regions (rDNAs). Design: BacterialrDNAsweredetectedbyPCRamplificationofsemenDNA.Conditionswereadjustedtodetect only abundant organisms, no fewer than 20,000 bacteria/mL of semen.
