Abstract:

The clinical signs and gross and microscopic lesions of Lassa virus infection in the rhesus monkey are described. Of 17 monkeys infected with Lassa virus, nine died or were killed when moribund. The clinical signs were lethargy, aphagia, constipation, fever, conjunctivitis, and skin rash. Pulmonary congestion, pleural effusion, pericardial edema, hydropericardium, and a few visceral hemorrhages were present grossly. Major microscopic lesions were necrotizing hepatitis and interstitial pneumonia. Other microscopic changes were present in the heart, small intestine, spleen, lymph nodes, kidney, urinary bladder, adrenal glands, and central nervous system however, most of these lesions were mild. In fact, death could not always be attributed to the morphologic changes therefore, function alterations must be examined.
