ABSTRACT
Objective To establish two PCR assays to rapidly and simultaneously detect U.parvum and U.urealyticum.Methods Two PCR assays were established through designing two sets of specific primer targeting urease gene B of U.parvum and U.urealyticum,respectively.The standard strains of U.parvum and U.urealyticum and the clinical samples were detected by these PCR assays and PCR products of the standard strains and two clinical specimens were directly sequenced and carried out specific and sensitive assays.Forty-eight clinical specimens were tested for culture and the PCR assays and tow methods were compared.Results The standard strains of U.parvum,U.urealyticum and the clinical specimens were successfully and differentially detected by the PCR assays and the sequencing results were found to have a complete similarity to the GenBank sequences.The 14 strains of other bacterial genera including 5 strains that produced urease were not amplified by these PCR assays.Each assay had a detection limit of 10 copies/?l of plasmid DNA.The positive rate in 48 clinical specimens by PCR(54.2%)was higher than that by culture(39.6%)(P
