title: Transabdominal ultrasonographic findings in goats with paratuberculosis.
abstract: This study describes the transabdominal ultrasonographic findings in 54 goats with confirmed Johne's disease (JD). Compared with the control group (0.8 ± 0.4 mm thick), the test group presented with mild (2.8 ± 0.2 mm), moderate (4.2 ± 0.4 mm), and severe (6.9 ± 1.1 mm) thickening of the intestinal wall. The most outstanding ultrasonographic findings were pronounced enlargement of the mesenteric lymph nodes in 49 goats. In 36 goats, the enlarged lymph nodes showed a hypoechoic cortex and a hyperechoic medulla. In 7 goats, the cortex and medulla were hypoechoic. In 5 goats, the cortex and the medulla could not be differentiated. In the remaining cases, the cortex and medulla contained small hypoechoic lesions. Necropsy findings included enlarged mesenteric lymph nodes in 52 goats and thickening of the small intestinal wall in 30 goats. Compared with the postmortem results, the antemortem ultrasound sensitivity in detecting intestinal wall thickness and enlarged mesenteric lymph nodes was 80% and 94%, respectively.
