The study was conducted in two selected districts of Southern Omo zones of Ethiopia, namely Hammer and Benna-Tsemay, during
November 2004 and May 2005 to determine the status of contagious caprine pleuropneumonia (CCPP). Participatory disease investigation
was conducted in the goat flocks owned by pastoralists of the districts. Participatory methods such as proportionate piling
and matrix scoring of diseases were used to characterise major diseases of goats. Clinical and post-mortem examinations and
isolation of the causative agent of CCPP were done. Serological tests were conducted using CFT. CCPP (locally termed Sompo) ranked as the first important disease of goats in the study area. Local perception of causes and signs of CCPP were described.
Matrix scoring between groups revealed that disease signs and causes showed weak, moderate and good agreement by Kendall’s
coefficient concordance (W = 0.21–0.99). The overall sero-prevalence of CCPP was 15.5%. The causative agent was isolated from
sick animals in the lab. The characteristic clinical signs, gross lesions, bacteriological isolation of the causative agent
supported by participatory epidemiological disease investigation revealed that CCPP is a major disease of goats in the study
districts. Participatory epidemiology using indigenous knowledge could efficiently be used to generate sufficient information
with minimum cost, local materials and within reasonably short period of time, assisting the designing of feasible disease
control programme in developing countries. 相似文献

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. 相似文献

Livestock export is vital to the Somali economy. To protect Somali livestock exports from costly import bans used to control the international spread of disease, better certification of livestock health status is required. We performed quantitative risk assessment and cost-effectiveness analysis on different health certification protocols for Somali livestock exports for six transboundary diseases. 相似文献

300 goat serum samples from an export-oriented abattoir were tested for contagious caprine pleuropneumonia antibodies by the
complement fixation test. The disease prevalence was 31% with no significant differences (P > 0.05) between the regions “Borena”,
“Bale”, “Afar” and “Jinka” or the age of the goats (P > 0.05). Gross pathology and histopathology of the lung primary lesions
were indicative of pleuropneumonia caused by Mycoplasma capricolum subsp. capripneumoniae. 相似文献

The efficacy of danofloxacin (Advocin A180) was evaluated for the treatment of contagious caprine pleuropneumonia (CCPP) caused by Mycoplasma capricolum subsp. capripneumoniae. Ten healthy Angora goats, confirmed free of CCPP, were exposed to clinically affected animals from a natural outbreak in Thrace, Turkey. After 14 days exposure, 8 goats showed pyrexia ( > or = 41 degrees C). Shortly after, the Angora goats were divided randomly into two groups. Five of these were injected with danofloxacin (6 mg/kg subcutaneously), which was repeated after 48 h; the five remaining animals received saline. Goats were monitored clinically and blood samples were collected for serology. Animals with severe disease were withdrawn from the trial. Goats completing the study were euthanized at day 42. Lung tissue and bronchial fluid were collected for mycoplasma isolation. All danofloxacin-treated goats showed resolution of clinical disease by the end of the trial. Two saline-treated goats failed to complete the study owing to CCPP. Danofloxacin-treated goats showed fewer lung lesions and had significantly lower combined clinical scores than saline controls (p < 0.001). Danofloxacin was found to be highly effective in the treatment of CCPP in goats. 相似文献

A cross sectional study was conducted to determine the sero-prevalence of contagious caprine pleuroneumonia in three districts
of Tigray and Afar regions of Ethiopia namely; Kefta Humera, Alamata and Aba-‘alla. Proportions and chi-square test statistics
were used to analyze the data. From a total of 863 goats and 137 sheep tested, 282 (32.68%) and 25 (18.25%) were positive
for antibodies of Mycoplasma capricolum subsp. capripneumoniae respectively using complement fixation test (CFT). The seroprevalence of CCPP in goats among the three districts was statistically
significant (x2 = 76.00, p < 0.001). In this study there was no statistical significant variation in the seroprevalence of CCPP in both sexes
(x2 = 3.619, p = 0.0571) and age (x2 = 0.990, p = 0.095) groups. The finding of high seroprevalence of CCPP in sheep (18.25%) could indicate that sheep are potential
carriers of Mccp. 相似文献
