The most common etiologic agents of genital ulcer disease (GUD) are
herpes simplex virus type 1 (HSV-1), HSV-2, Treponema pallidum, and Haemophilus ducreyi. In an outpatient
clinic for sexually transmitted diseases in Amsterdam, The Netherlands,
specimens from 372 patients with GUD were collected from February to
November 1996. Sera were collected at the time of the symptoms and, for most patients, also during follow-up visits. Swabs in viral transport medium were used for HSV culture and for detection of DNA. The most
prevalent pathogen found was HSV-2, which was detected by culture in
35% of the patients and by PCR in 48% of the patients. Also, HSV-1
infection was more often detected by PCR (7.8%) than by culture
(5.6%). Evidence for an active infection with T. pallidum was found in 1.9% of the patients, using serological tests. A multiplex PCR for simultaneous T. pallidum and H. ducreyi DNA detection was positive for T. pallidum in
3.3% of the samples and for H. ducreyi in only 0.9% (3 out of 368) of the samples. The sensitivity of the PCR was superior to
that of culture for HSV detection and to that of serology for T. pallidum detection. Specific H. ducreyi
immunoglobulin G antibodies were detected in sera of 5.2% of the
patients, with no concordance between serology and PCR. In 37% of the
cases, none of the tested microorganisms was detected. Performance of
PCR in addition to conventional techniques significantly improved the
diagnosis of GUD.
