Haemophilus ducreyi is a well recognised causative agent of genital ulcers and chancroid. We report two unusual cases of non-sexually transmitted H. ducreyi infection leading to chronic lower limb ulcers. Both patients were Australian expatriates visiting Australia from the Pacific Islands--one from Papua New Guinea and the other from Vanuatu.
The detection of herpes, chancroid, and syphilis in genital ulcers is done by PCR. This is not so for lymphogranuloma venereum (LGV). We report on the use of a PCR with digestion that differentiates the LGV biovar from the trachoma biovar. Our findings suggest that the clinical description of LGV in current textbooks is incomplete.
Haemophilus ducreyi is the causative agent of the sexually transmitted disease chancroid. We have identified a hemolytic activity expressed by H. ducreyi. This activity is most readily detected when horse erythrocytes are used as a target; however, low levels of activity can be detected with sheep, human, or rabbit erythrocyte targets. The activity is heat labile and protease sensitive.
Haemophilus ducreyi, which causes chancroid, has emerged as a cause of pediatric skin disease. Isolation of H. ducreyi in low-income settings is challenging, limiting phylogenetic investigation. Next-generation sequencing demonstrates that cutaneous strains arise from class I and II H. ducreyi clades and that class II may represent a distinct subspecies.
Haemophilus ducreyi causes chancroid and has recently been shown to be a significant cause of cutaneous lesions in tropical or subtropical regions where yaws is endemic. Here, we report the draft genome assemblies for 11 cutaneous strains of Haemophilus ducreyi, isolated from children in Vanuatu and Ghana.
Paraphimosis usually develops when a tight foreskin is retracted over the glans penis for a prolonged period. Many esoteric aetiologies have been implicated in the development of paraphimosis including piercing the foreskin, Plasmodium falciparum infection, application of celadine juice to the foreskin, chancroid, pessaries and the implantation of pearls. We report the first two cases of paraph...
