摘要

Contagious bovine pleuropneumonia endangers animal health and local food production, making it one of the most important infectious diseases of livestock. In Africa, the herds undergo losses of up to 80%, and survivors often become chronic carriers with decreased production of milk and meat. Namibe province is considered one of the most affected by the disease, but the impact thereof and the factors associated with its occurrence are unknown. The study was designed based on participatory epidemiology involving 87 farmers from three municipalities of Namibe province and the support of traditional leaders and technicians of the state services in the province; a semi-structured questionnaire was used. The 67,8% of the farmers (59) reported dead animal and 64% pointed to the disease as a cause of death. Bibala was the most affected municipality, and cow was the animal category with the highest mortality (p0.001). The factors associated with mortality by this disease identified by logistic regression were: animal purchase to neighboring countries (OR:11.0 p0.001), dry season (OR: 3.0, p0.05), transhumance (OR:1.74, p0.05), and animal movement farther than 50 km (OR:4.81, p0.05). The PCB and its risk factors were demonstrated to be a significant part of the livestock problems to be treated with priority.
