3. Eradicating chancroid.
Match Strength: 11.698

Genital ulcers are important cofactors of HIV transmission in the countries most severely affected by HIV/AIDS. Chancroid is a common cause of genital ulcer in all 18 countries where adult HIV prevalence surpasses 8% and is rare in countries with low-level HIV epidemics. Haemophilus ducreyi, the causative organism of chancroid, is biologically vulnerable and occupies a precarious epidemiological niche. Both simple, topical hygiene and male circumcision greatly reduce risk of infection and several classes of antibiotics--some of which can be administered in single-dose treatment regimens- ... Read More »

4. An immunohistochemical analysis of naturally occurring chancroid.
Match Strength: 11.432

Haemophilus ducreyi is a major cause of genital ulcer disease in many developing countries and is associated with augmented transmission of human immunodeficiency virus (HIV). However, the mechanisms through which H. ducreyi produces ulceration are poorly understood. The characteristics of the host response to H. ducreyi and the pathobiology of its potential contribution to increased HIV susceptibility are not known. Chancroid ulcer biopsies from 8 patients were analyzed histologically and immunohistochemically. All biopsies had perivascular and interstitial mononuclear cell infiltrates that ... Read More »

5. Immunization with the Haemophilus ducreyi hemoglobin receptor HgbA protects against infection in the swine model of chancroid.
Match Strength: 11.040

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 demonstrate that an experimental HgbA vaccine efficiently prevents chancroid, as determined by several parameters. Histological sections of immunized animals lacked typical microscopic features of chancroid. ... Read More »

7. Male circumcision and risk of syphilis, chancroid, and genital herpes: a systematic review and meta-analysis.
Match Strength: 9.213

OBJECTIVES: Male circumcision is associated with reduced risk of HIV infection. This may be partly because of a protective effect of circumcision on other sexually transmitted infections (STI), especially those causing genital ulcers, but evidence for such protection is unclear. Our objective was to conduct a systematic review and meta-analyses of the associations between male circumcision and infection with herpes simplex virus type 2 (HSV-2), Treponema pallidum, or Haemophilus ducreyi. METHODS: Electronic databases (1950-2004) were searched using keywords and text terms for herpes simplex, ... Read More »

8. Localization of Haemophilus ducreyi in naturally acquired chancroidal ulcers.
Match Strength: 8.847

Haemophilus ducreyi causes the sexually transmitted genital ulcer disease chancroid. In human inoculation experiments, bacteria colocalize with neutrophils and macrophages but remain extracellular. The organism also colocalizes with collagen and fibrin but not with keratinocytes, fibroblasts, laminin, or fibronectin. These relationships are established by 48 h postinoculation and persist through the pustular stage of disease. To extend these observations to the ulcerative stage of disease, and to compare results in the human model with those of natural disease, we obtained biopsies from ... Read More »

9. The Cytolethal Distending Toxin of Haemophilus Ducreyi Aggravates Dermal Lesions in a Rabbit Model of Chancroid
Match Strength: 8.128

Haemophilus ducreyi, the etiologic agent of the sexually transmitted disease chancroid, produces a cytolethal distending toxin (HdCDT) that inhibits cultured cell proliferation, leading to cell death. A rabbit model of dermal infection was used to investigate the roles of H. ducreyi bacteria and HdCDT in the development, clinical appearance, and persistence of infection. A non-toxin producing H. ducreyi strain, and for comparison purposes a non-capsulated Haemophilus influenzae strain, were inoculated intradermally, with and without co-administration of purified HdCDT. Co-administration of ... Read More »

10. Expression of Haemophilus ducreyi collagen binding outer membrane protein NcaA is required for virulence in swine and human challenge models of chancroid.
Match Strength: 7.837

Haemophilus ducreyi, the etiologic agent of the sexually transmitted genital ulcer disease chancroid, has been shown to associate with dermal collagen fibers within infected skin lesions. Here we describe NcaA, a previously uncharacterized outer membrane protein that is important for H. ducreyi collagen binding and host colonization. An H. ducreyi strain lacking the ncaA gene was impaired in adherence to type I collagen but not fibronectin (plasma or cellular form) or heparin. The mutation had no effect on serum resistance or binding to HaCaT keratinocytes or human foreskin fibroblasts in ... Read More »

25. Sexually transmitted diseases in HIV-infected persons.
Match Strength: 4.271

It appears incontestable that there is a link between genital ulcer disease and HIV infection. On the one hand the natural history and response to therapy of syphilis, HSV-2, and chancroid are all modified by the immunosuppressive effects of HIV infection. On the other hand, HIV transmission is probably facilitated by the disruption of the normal epithelial barriers of the genital organs caused by these ulcerative infections. Information is somewhat less convincing that a similar association exists between the nonulcerative STDs (trichomonas, gonorrhea, chlamydial infections) and HIV. ... Read More »

Haemophilus ducreyi, the causative agent of chancroid, produces a lipooligosaccharide (LOS) which terminates in N-acetyllactosamine. This glycoform can be further extended by the addition of a single sialic acid residue to the terminal galactose moiety. H. ducreyi does not synthesize sialic acid, which must be acquired from the host during infection or from the culture medium when the bacteria are grown in vitro. However, H. ducreyi does not have genes that are highly homologous to the genes encoding known bacterial sialic acid transporters. In this study, we identified the sialic acid ... Read More »

OBJECTIVE: To understand the changing impact of HSV-2 and other sexually transmitted infections (STI) on HIV incidence over time in four sub-Saharan African cities using simulation models. METHODS: An individual-based stochastic model was fitted to demographic, behavioural and epidemiological data from cross-sectional population-based surveys in four African cities (Kisumu, Kenya; Ndola, Zambia; Yaounde, Cameroon; and Cotonou, Benin) in 1997. To estimate the proportion of new HIV infections attributable to HSV-2 and other STIs over time, HIV incidence in the fitted model was compared to that ... Read More »

40. Biosynthesis of sialylated lipooligosaccharides in Haemophilus ducreyi is dependent on exogenous sialic acid and not mannosamine. Incorporation studies using N-acylmannosamine analogues, N-glycolylneuraminic acid, and 13C-labeled N-acetylneuraminic acid.
Match Strength: 3.534

Haemophilus ducreyi is a Gram-negative bacterium that causes chancroid, a sexually transmitted disease. Cell surface lipooligosaccharides (LOS) of H. ducreyi are thought to play important biological roles in host infection. The vast majority of H. ducreyi strains contain high levels of sialic acid (N-acetylneuraminic acid, NeuAc) in their LOS. Here we investigate the biosynthetic origin of H. ducreyi sialosides by metabolic incorporation studies using a panel of N-acylmannosamine and sialic acid analogues. Incorporation of sialosides into LOS was assessed by matrix-assisted laser desorption ... Read More »

41. Changing trends in sexually transmitted infections at a Regional STD Centre in north India.
Match Strength: 3.417

BACKGROUND & OBJECTIVES: Sexually transmitted infections (STIs) a major public health problem in India show various trends in different parts of the country. However, there are limited data on the changing profile of laboratory proven STIs in the same clinic over the years. The present study was thus aimed to determine the changing trends of the profile of STIs and HIV seropositivity in STD clinic attendees over a 15 yr period, and also to detect change, if any, in the antimicrobial resistance pattern of Neisseria gonorrhoeae. METHODS: The STIs were diagnosed clinically and confirmed by ... Read More »

43. The role of Haemophilus ducreyi bacteria, cytotoxin, endotoxin and antibodies in animal models for study of chancroid
Match Strength: 3.155

Haemophilus ducreyi cytotoxin-positive and -negative strains as well as bacterial sonicates and lipooligosaccharides (LOS) from such strains were evaluated for the capacity to produce dermonecrotic lesions, especially ulcers, after intradermal injections to rabbits and to different mouse strains, including nude mice. Dermonecrotic lesions of the ulcerous type were observed within 4 days and they were developed in both rabbits and mice with about 10(7) colony forming units (cfu) of H. ducreyi. Viable bacteria were isolated from the lesions up to 9 days after inoculation. All lesions healed ... Read More »

44. Knowledge of Aids and Other Sexually Transmitted Diseases Among Women Attending a Family Planning Clinic in Nairobi, Kenya
Match Strength: 3.118

We interviewed 1,716 women attending a family planning clinic in Nairobi between January 1990 and May 1991 about their knowledge of the acquired immunodeficiency syndrome (AIDS) and other sexually transmitted diseases (STDs). When participants in the study were asked to name spontaneously the STDs they knew, more than 90% of the women named gonorrhea and AIDS, and 75.0% named syphilis; 65.4% could name two or more signs of AIDS; and 96.9%, 66.5%, and 58.3% mentioned sexual transmission, transmission via blood transfusion, and perinatal transmission, respectively, as routes of transmission of ... Read More »

46. Historical account of venereal diseases in Mexico.
Match Strength: 2.917

This paper reviews the history of sexually acquired diseases in Mexico. It is divided into four major chronological sections which discuss social attitudes and values, the development of services and of official policy, and historical epidemiology. PIP: During the pre-conquest period of 1325-1521, Mexico was inhabited by more than 80 distinct ethnographic groups, disconnected, and with cultures less developed than those of the Aztec and Maya. Male polygamy was accepted only among nobles, although warriors received sexual services from groups of women who lived isolated from society. Adultery ... Read More »
