Surveillance and testing strategies for the diagnosis of CBPP: Results of the FAO/IAEA Co-ordinated Research Programme on the monitoring of CBPP in Africa

摘要

Reliable and efficient diagnostic tests for the serological diagnosis of infectious diseases are the cornerstone of any disease control strategy. The requirements for diagnostic tests depend on the purpose of the diagnostic testing and the epidemiological needs. The monitoring of a region wide vaccination programme has different needs compared to the needs of export certification of individual animals. In the case of contagious bovine pleuropneumonia (CBPP) countries adjacent to infected areas may want to confirm the absence of the disease relying on serology and slaughterhouse inspections, Positive test results will lead to follow up investigations and, depending on the diagnostic tests used, may result in substantial expenses, Highly specific tests with a high positive predictive value are needed to limit the amount of follow up work.
