an investigation of genital ulcers in jackson, mississippi, with use of a multiplex polymerase chain reaction assay: high prevalence of chancroid and human immunodeficiency virus infection.in 1994, an apparent outbreak of atypical genital ulcers was noted by clinicians at the sexually transmitted disease clinic in jackson, mississippi. of 143 patients with ulcers tested with a multiplex polymerase chain reaction (pcr) assay, 56 (39%) were positive for haemophilus ducreyi, 44 (31%) for herpes simplex virus, and 27 (19%) for treponema pallidum; 12 (8%) were positive for > 1 organism. of 136 patients tested for human immunodeficiency virus (hiv) by serology, 14 (10%) were hiv-seropos ...19989806035
molecular characterization of haemophilus ducreyi strains from jackson, mississippi, and new orleans, louisiana.chancroid, a sexually transmitted disease caused by haemophilus ducreyi, is one of the most common genital ulcer diseases in developing countries. in the united states, while less common, the disease has been associated with outbreaks in inner cities, particularly among persons who engage in sex for drugs or money. two outbreaks of chancroid were recently studied in the united states, one in new orleans (from 1990 to 1992) and one in jackson, mississippi (from 1994 to 1995). by use of ribotyping ...199910228064
comparison of enzyme immunoassays for antibodies to haemophilus ducreyi in a community outbreak of chancroid in the united states.the performance of two eias (adsorption eia and lipooligosaccharide [los] eia) that detect antibodies to haemophilus ducreyi was evaluated with serum specimens obtained from 163 patients (96 with genital ulcer disease [gud]). paired serum specimens (initial and follow-up) were obtained from 52 of the gud patients. by use of initial serum specimens from 82 gud patients whose etiologic agents for their ulcers had been identified, the adsorption eia had a sensitivity and specificity for chancroid o ...19979180178
chancroid detected by polymerase chain reaction--jackson, mississippi, 1994-1995. 19958578414
chancroid detected by polymerase chain reaction--jackson, mississippi, 1994-1995.chancroid is a sexually transmitted disease (std) caused by infection with haemophilus ducreyi and is characterized by genital ulceration. chancroid is underreported in the united states (1), reflecting, in part, difficulties in diagnosis because of clinical similarities between chancroid and other ulcerative stds. in addition, laboratory confirmation by culture is 53%-84% sensitive and often is unavailable in clinical settings (2). in september 1994, clinicians at the district v std clinic of t ...19957616954
