Haemophilus ducreyi is a fastidious gram-negative bacillus that causes the
sexually transmitted infection chancroid. Chancroid is a major genital
ulcerative disease in Africa, Southeast Asia, the Caribbean, and Latin
America and is of increasing concern in the United States. Genital
ulcerative disease and chancroid in particular have been associated with
facilitating the transmission of human immunodeficiency virus. The
diagnosis of chancroid based on the clinical appearance of the genital
lesion or on the isolation of H. ducreyi on selective medium is relatively
insensitive. However, recent advances in nonculture diagnostic tests have
enhanced our ability to diagnose chancroid. There has been renewed interest
in understanding the pathogenesis of H. ducreyi. In vitro and in vivo
models have been developed to help identify important virulence
determinants. Through the use of biochemical and molecular techniques,
macromolecular components that may be important in virulence have been
identified.
