title: Observations on trichinosis in the rhesus monkey.
abstract: Monkeys infected with 2.0 larvae/g body weight died 31-41 days post-infection (PI): two of three monkeys infected with 1.0 larva/g body weight became moribund and were sacrificed at 50 days, but six of six monkeys infected with 1.0 larva/g body weight were healthy 225 days PI. Periorbital and facial edema and eosinophilia were observed in all groups during the second week PI, and myalgia and stiffening of joints was observed during the third week. High numbers of encyse, biceps brachii and deltoideus. Adult worms were recovered from the intestine 49 days PI. The morphological changes were essentially similar to those seen in humans and a generalized lymphoid hyperplasia was not observed. Thus, rhesus monkeys develop trichinosis which show similarities clinically, pathologically and morphologically to human disease.
