Project descriptions
Buruli ulcer related ongoing projects

1. Research Title
Co-infection of M. tuberculosis or M ulcerans with Mansonella perstans in Ghana, Benin and Cameroun (Map2Co)

Date: 2013- 2016

Summary: The objectives of this study include:

• Epidemiology of current M. perstans infected individuals and vectors and associated prevalence of mycobacterial diseases
• Improvements in M. perstans/Wolbachia detection and establishment of a mouse model of M. perstans infection
• Characterize the influence of M. perstans co-infections on immunity and clinical picture of individuals with TB and BUD
• Determine influence of M. perstans infection and doxycycline treatment on host immunity against mycobacterial infection and disease susceptibility

Sponsor: German Research Foundation (DFG)


  • Dr Ellis Owusu-Dabo KCCR-KNUST
  • Dr Alex Debrah KNUST

Co-Principal Investigators:

  • Prof. Dr. Marc Jacobsen, University of Duesseldorf, Germany
  • Prof. Dr. med. Achim Hoerauf, University of Bonn, Germany
  • Prof Samuel Wanji, University of Buea, Cameroun

2. Research Title:

Pathogenesis and management of M. ulcerans disease, Buruli ulcer (Buruli_Path)

Date: 2012 – 2017

Summary: The objectives of this study include:

  • To identify markers for a rapid response to antibiotic treatment of Mu disease
  • To identify predictive markers of paradoxical reactions in Mu disease
  • To investigate the pathogenesis of oedematous lesions in Mu disease

Sponsor: MRC/DfID UK

Co Principal Investigator:
• Mark Wansbrough-Jones,Division of Clinical Sciences, Infectious Diseases, St George’s, University of London


  • Dr Caroline Demangel, Pasteur Institute Paris France
    – Hepatitis B and C related ongoing projects

3. Collaborative study with the University of Liverpool (HEPIK) and South Tees Hospital (Middlesbrough)

Research Title:
HIV and Hepatitis B virus co-infection; Antiviral therapy and drug resistance; HIV genetic variability.

Dates: 2010-2014

Together with the University College of London I am accessing lamivudine-containing anti-HIV therapy. As lamivudine also has partial activity against hepatitis B, I am interested in exploring how drug pressure is influencing the genetic evolution of both HIV and hepatitis B virus, and ultimately clinical outcomes in these cohorts. Preliminary data show suboptimal suppression of hepatitis B replication, and evolution of both drug resistant mutants and other variants that carry a highly mutated hepatitis B surface antigen. These mutants represent a significant public health threat as they can escape recognition by diagnostic assays and vaccine-induced neutralising antibodies

Funding body: Leverhulme-Royal Society Africa award

• Prof George Bedu-Addo

Co Principal Investigator:
• Prof Anna Maria Geretti, University of Liverpool, UK
• Dr David Chadwick, South Tees Hospital, (Middlesbrough)

4. Research Title:
Detection of Chronic HCV infection and recovery among a cohort of HCV positive blood donors in Kumasi.

Date 2013-14

To compare HCV third generation EIA and RIBA assays results to the previously used HCV rapid screening test results. To develop criteria to define chronic infection and HCV recovery based on assay results that will be used in future studies.

Sponsor: Loyola University Medical Center

Co Principal Investigator:
• Jennifer Layden, Assistant Professor of Medicine and Public Health Sciences, Loyola University Medical Center, Chicago USA
