Description

Preface

Since the publication of the first edition of Part 2 District Laboratory Practice in Tropical Countries in 2000, the work of many district laboratories continues to be dominated by the on-going HIV/AIDS pandemic, increases in the prevalence of tuberculosis and other HIV-related infections and more recently, the requirement for laboratory monitoring of antiretroviral therapy.
This new edition includes an update on HIV disease/AIDS, recently developed HIV rapid tests to diagnose HIV infection and screen donor blood, and current information on antiretroviral drugs and the laboratory monitoring of antiretroviral therapy.

Information on the epidemiology and laboratory investigation of other pathogens has also been brought up to date. Several new, rapid, simple to perform immunochromatographic tests to assist in the diagnosis of infectious diseases are described, including those for brucellosis, cholera, dengue, leptospirosis, syphilis and hepatitis. Recently developed IgM antibody tests to investigate typhoid fever are also described. The new classification of salmonellae has been introduced.
Details of manufacturers and suppliers now include website information and e-mail addresses. Websites are also included that provide up to date information on water and sanitation initiatives, and diseases such as tuberculosis, cholera, leptospirosis, mycetoma, HIV/AIDS and other sexually transmitted infections.
Where required the haematology and blood transfusion chapters have been updated, including a review of haemoglobin measurement methods in consideration of the high prevalence of anaemia in developing countries.
It is hoped that this new edition of Part 2 and recently published second edition of Part 1 District
Laboratory Practice in Tropical Countries will continue to help and motivate those working in district laboratories and those responsible for the management of district laboratory services, training and continuing education of district laboratory personnel.
