Chancroid and Haemophilus ducreyi.
Haemophilus ducreyi is the causative agent of chancroid, one of the genital ulcerative diseases. H. ducreyi is the major cause of genital ulcer disease in Africa and Southeast Asia and is of increasing concern in the United States. Definitive diagnosis of chancroid requires the isolation and identification of H. ducreyi, but isolation of this organism is difficult and the available medium is no...
متن کاملImmunization with the Haemophilus ducreyi hemoglobin receptor HgbA protects against infection in the swine model of chancroid.
The etiologic agent of chancroid is Haemophilus ducreyi. To fulfill its obligate requirement for heme, H. ducreyi uses two TonB-dependent receptors: the hemoglobin receptor (HgbA) and a receptor for free heme (TdhA). Expression of HgbA is necessary for H. ducreyi to survive and initiate disease in a human model of chancroid. In this study, we used a swine model of H. ducreyi infection to demons...
متن کاملUrethral infection with Haemophilus ducreyi in men.
Carriage of Haemophilus ducreyi has not been adequately investigated in men, and its role in urethritis is unknown. In this study 456 men with H. ducreyi-culture positive genital ulcers were investigated. Among these men, 16 (3.5%) had urethritis. H. ducreyi was isolated from the urethra of nine men (1.9%). Of 57 men who had chancroid but not urethritis, none had H. ducreyi isolated from the ur...
متن کاملVirtual screening of phytochemicals to novel targets in Haemophilus ducreyi towards the treatment of Chancroid
Conventionally, drugs are discovered by testing chemically synthesized compounds against a battery of in vivo biological screens. Information technology and Omic science enabled us for high throughput screening of compound libraries against biological targets and hits are then tested for efficacy in cells or animals. Chancroid, caused by Haemophilus ducreyi is a public health problem and has be...
متن کاملSimplified PCR for detection of Haemophilus ducreyi and diagnosis of chancroid.
A simplified PCR was developed for detection of Haemophilus ducreyi in samples from chancroid patients. The strategy included a straightforward chloroform extraction sample preparation method, a one-tube nested PCR to minimize contamination risks, and a colorimetric method for detection of products. Primers were designed from published nucleotide sequences of the 16S rRNA gene of H. ducreyi, wi...
