Mapping the distribution of yaws and Haemophilus ducreyi in the western north region of Ghana [PDF]

BMC Infectious Diseases
Background Treponema pallidum subspecies pertenue and Haemophilus ducreyi cause skin ulcers in impoverished communities. Historical serologic records from Ghana focus on T. pallidum, omitting potential H. ducreyi cases. The objective of this study was to

Haemophilus ducreyi Associated with Skin Ulcers among Children, Solomon Islands [PDF]

Emerging Infectious Diseases, 2014
During a survey of yaws prevalence in the Solomon Islands, we collected samples from skin ulcers of 41 children. Using PCR, we identified Haemophilus ducreyi infection in 13 (32%) children.

A high-resolution view of the immune and stromal cell response to Haemophilus ducreyi infection in human volunteers [PDF]

mBio
Haemophilus ducreyi causes the genital ulcer disease chancroid and cutaneous ulcers in children. To study its pathogenesis, we developed a human challenge model in which we infect the skin on the upper arm of human volunteers with H.

Molecular phylogenetic analysis of non-sexually transmitted strains of Haemophilus ducreyi. [PDF]

PLoS ONE, 2015
Haemophilus ducreyi, the etiologic agent of chancroid, has been previously reported to show genetic variance in several key virulence factors, placing strains of the bacterium into two genetically distinct classes.

LAMP4yaws: Treponema pallidum, Haemophilus ducreyi loop mediated isothermal amplification − protocol for a cross-sectional, observational, diagnostic accuracy study [PDF]

BMJ Open, 2022
Introduction Yaws, caused by the bacterium Treponema pallidum subsp. pertenue, is a neglected tropical disease targeted for eradication by 2030. Improved diagnostics will be essential to meet this goal.

The Laboratory Diagnosis of Haemophilus ducreyi [PDF]

Canadian Journal of Infectious Diseases and Medical Microbiology, 2005
Chancroid is a sexually transmitted infection caused by Haemophilus ducreyi. This fastidious, Gram-negative coccobacilli dies rapidly outside the human host, making diagnostic testing using culture methods difficult.

Functional Study of Haemophilus ducreyi Cytolethal Distending Toxin Subunit B [PDF]

Toxins, 2020
The Cytolethal Distending Toxin (CDT) is produced by many Gram-negative pathogenic bacteria responsible for major foodborne diseases worldwide. CDT induces DNA damage and cell cycle arrest in host-cells, eventually leading to senescence or apoptosis ...

Detection of Haemophilus ducreyi from environmental and animal samples in Cameroon. [PDF]

PLoS Neglected Tropical Diseases
BackgroundChildren in parts of Africa, the South Pacific, and Southeast Asia frequently develop cutaneous ulcers caused by two bacteria: Haemophilus ducreyi (HD) and Treponema pallidum subspecies pertenue (causative agent of yaws).

Haemophilus ducreyi Cutaneous Ulcer Strains Are Nearly Identical to Class I Genital Ulcer Strains. [PDF]

PLoS Neglected Tropical Diseases, 2015
BackgroundAlthough cutaneous ulcers (CU) in the tropics is frequently attributed to Treponema pallidum subspecies pertenue, the causative agent of yaws, Haemophilus ducreyi has emerged as a major cause of CU in yaws-endemic regions of the South Pacific ...
