Contribution of ultrasound examination in diagnosing platynosomiasis and correlation with macro and microscopic findings in callitrichids kept under human care

Platynosomiasis in non-human primates kept under human care causes chronic disease of the bile ducts and liver, which initially presents with nonspecific signs and can culminate in the death of the animal. Diagnosing this disease is a challenge, and an ultrasound examination can be an excellent tool when it is suspected.
