Background: The most important form of caprine arthritis encephalitis virus in the goat is the arthritic, generally observed in animals over eight months of age. Differently in sheep, there is less arthritis incidence, affecting 2-3-year-old animals. The clinical alterations frequently affect goat joints, and an increase in the joint consistency and size is observed. The objective of the present study was to standardize the ultrasound technique to access joints in animals infected with the caprine arthritis encephalitis virus (CAEV), so that it can be a complimentary support tool for diagnosis and animal management. Materials, Methods & Results: Animals were examined from farms located in the municipality of Teresina, state of Piauí, Brazil. For this, the M-Turbo, Sonosite Fujifilm ultrasonography apparatus was used, attached to a linear transducer with 10-13 MHz frequency. The ultrasound examination analyzed three regions: patella-humerus joint, carpal and tarsal joints. The patella-humerus joint was characterized by its concave convex surface. The surface of the head humerus was a fine hyperechoic line composed by the junction between the joint cartilage and the subcontinent bone. The sub patella muscle was visible and its fibers present a parallel and hypoechogenic pattern compared to bone tissue. A discreet muscle edge with echogenicity was observed separating the [...](AU)
