    Area of Science:

    • Public Health Microbiology
    • Infectious Disease Epidemiology
    • Environmental Health Surveillance

    Background:

    • Southern Africa faced a significant cholera epidemic, necessitating a coordinated response.
    • Existing surveillance and laboratory infrastructure were insufficient to manage the outbreak effectively.
    • The need for a dedicated regional center to address the growing public health threat was identified.

    Purpose of the Study:

    • To establish and describe the activities of a new regional cholera reference laboratory and surveillance centre.
    • To detail methodologies for the isolation of Vibrio cholerae and other relevant bacteria.
    • To foster regional collaboration in cholera control and prevention efforts.

    Main Methods:

    • Isolation of Vibrio cholerae from diverse environmental and clinical samples, including sewage, water, seafood, patients, and carriers.
    • Specific techniques for identifying and characterizing Vibrio cholerae, including non-agglutinable strains.
    • Methods for isolating Vibrio parahaemolyticus from selected specimen types.

    Main Results:

    • Successful establishment of a functional regional cholera reference laboratory and surveillance centre.
    • Detailed protocols for Vibrio cholerae isolation from a wide range of sources were implemented.
    • Isolation of non-agglutinable Vibrio cholerae and Vibrio parahaemolyticus confirmed the presence of related pathogens.

    Conclusions:

    • The regional laboratory is crucial for monitoring and controlling cholera in southern Africa.
    • Standardized isolation methods enhance surveillance accuracy and comparability across the region.
    • International collaboration is vital and shows promising results in combating the spread of cholera.
