A Serological Investigation into Contagious Caprine Pleuropneumonia (CCPP) in Ethiopia

For a comparison of serological tests for CCPP, sera from 767 goats were examined. They were subjected to three tests: complement fixation test (CFT) with Mycoplasma capricolum subspecies capripneumoniae antigen; blocking ELISA (B-ELISA) with Mycoplasma capricolum subspecies capripneumoniae antigen; and CFT with Mycoplasma mycoides subspecies mycoides small colony type antigen. Antibodies were detected by these three tests in 23%, 2% and 12%, respectively, of sera from districts in which CCPP had not been reported, and in 60%, 83% and 87%, respectively, in sera from areas in which CCPP had been reported. The specificity of the tests is discussed. The use of the B-ELISA test for the diagnosis and for epidemiological studies of CCPP is strongly recommended.     

Investigations of Outbreaks of Contagious Caprine Pleuropneumonia in Eritrea

Mycoplasmas were isolated from freeze-dried lung samples from goats from the western lowlands of Eritrea suspected of being affected by contagious caprine pleuropneumonia. The goats belonged to two herds in which mortality and morbidity rates were high. Mycoplasma capricolum subsp. capripneumoniae was identified in most samples by the polymerase chain reaction and by conventional serological tests. The latex agglutination test detected more positive serum samples in both herds than did the complement fixation test. Following cloning, the isolates of M. capricolum subsp. capripneumoniae were analysed biochemically and shown to be metabolically similar. They oxidized glucose, N-acetylglucosamine, pyruvate and L-lactate with high affinity and mannose, glucosamine and 2-oxobutyrate with low affinity; they were unable to utilize maltose, trehalose, fructose or ethanol. Major improvements were seen in the growth yield of the Eritrean strains with the addition of pyruvate to the medium. Thus, it may be that organic acids are important energy sources for these strains and may be used in addition to or in place of glucose. In contrast to most other strains of the M. mycoides cluster, the Eritrean strains produced large amounts of hydrogen peroxide during the oxidation of NADH by lysed cells. This characteristic had previously been reported for strain M. F38, the type strain of M. capricolum subsp. capripneumoniae, although strain F38 did not metabolize sugars. Hydrogen peroxide has long been considered a pathogenicity factor in mycoplasma infections. This is the first isolation of M. capricolum subsp. capripneumoniae from Eritrea.
