Resumo: |
The classical swine fever virus causes a highly contagious disease in domestic and wild pigs, characterized by leading to great economic losses, for both large and small farming. The disease may present as acute, chronic, delayed, or persistent asymptomatic, which depend on the virulence of the strain, animal age, immune status, gestation period. The disease is notifiable and control measures are listed in the National Program to Swine Health from Ministry of Agriculture, Livestock and Supply. Brazil has an area considered as free of classical swine fever which is composed of the major part of states and non-free zone, which has the majority of states in the North and Northeast Brazil. Outside the area considered free of classical swine fever outbreaks continue to occur sporadically, but the proposal of the Ministry of Agriculture, Livestock and Supply is to eradicate the disease throughout the country. The diagnosis of infection may be done by viral isolation and virus identification in cell culture, wich is considered the gold standard, using the immunofluorescence and immunoperoxidase technics. Samples were analyzed by this methods in the National Agriculture and Livestock Laboratory of Pernambuco State, from 149 swines with clinical suspicion of classical swine fever during the period from 1999 to 2009, from the states of Pará and Amapá – North region, and Maranhão, Ceará, Rio Grande do Norte, Paraíba e Pernambuco of Northeast region, Among the swines analyzed, 51 were infected with the classical swine fever virus. The necropsial findings were mostly hemorragic, tipical of the classical form of the disease. The afected farms were in most low-level technificated. The results showed that the presence of positive animals is high, with the agent present in most states in the Northeast and North, and that the application of effective preventive measures in the field can reduce or prevent the emergence of cases and outbreaks of disease. |
