Geral aspect on circovirose in pigs

Abstract

The porcine circovirus causes one of the largest damage in the raising and exploration of swines in Brazil and all over the world. The generalized infection involves various body systems. The end result is a significant delay in growth and culling of affected piglets. It is a disease characterized by depression, progressive weight loss, tachypnea, dysponea, jaundice, skin paleness and diarrhea in pigles from five to five to 13 weeks of age. At necropsy, the most important findings are the increased volume of lymph nodes and not collapsed lungs with consolidated areas, mainly in the cranial lobes and the anterior portion of the medium lobes. The infection diagnosis is based on the symptomatology analysis and the isolation of the virus, in the identification of antigens or the viral genoma in suspected animals, from macroscopic and microscopic lesions, hematological and biochemical anormalities. The objective of this review was to do a survey about Circovirosis swine.
