title: Contagious bovine pleuropneumonia in northern Tanzania, culture confirmation and serological studies.
abstract: After an absence of about 25 years contagious bovine pleuropneumonia (CBPP) appeared again in 1990 in Tanzania. It was preceded by a spread in Kenya to an area bordering Tanzania. Due to the frequent cattle movements across the border it was soon introduced into Loliondo in northern Tanzania. One month after the first cases, CBPP was suspected in a total of 9 herds comprising 1,500 cattle. However, few animals showed clear clinical signs and frequent antibiotic treatment at an early stage further obscured the clinical picture. In one herd with acute cases, the diagnosis was confirmed by autopsy and Mycoplasma mycoides subsp. mycoides, SC type, was isolated. From this herd several serum samples were positive in the complement fixation test and gave high absorbance values in an ELISA with M. mycoides subsp. mycoides antigen. From 5 other herds with suspected cases blood samples were negative by the complement fixation test but in the enzyme-linked immunosorbent assay at least one in each herd was positive.
