Acta vet. scand. 2004 45 167-179. - Contagious caprine pleuropneumonia CCPP is a major threat to goat farming in parts of Africa and Asia. It classically causes acute high morbidity and mortality early in infection but little is known of its long term epizootiology and course. In this study 10 goats were inoculated with Mycoplasma capricolum subsp. capripneumoniae M. capripneumoniae and then mixed with 15 goats for contact transmission. The disease course was monitored in each goat for 56-105 days whereafter the goats were killed and necropsied. Varying features signifying infection occurred in altogether 17 goats 7 inoculated 10 in-contact . Clinical signs were severe in 8 goats but no fatalities occurred. Only 6 goats had serum antibody titres against M. capripneumoniae in ELISA. Fourteen goats 5 inoculated 9 in-contact had chronic pleuropulmonary lesions compatible with CCPP at necropsy and 7 of those showed M. capripneumoniae antigen in the lung by immunohistochemistry.
