Thirty-four rhesus monkeys were inoculated with Mycobacterium leprae inoculum isolated from sooty mangabey monkeys with leprosy. Later it was learned that one of the M. leprae-donor mangabeys was asymptomatically infected with simian immunodeficiency virus (SIV). Thus, five of the rhesus monkey were coinoculated with M. leprae and SIV. Three of the five became SIV-positive and developed signs of leprosy and an AIDS-like illness. Two animals remained healthy. The coinoculated leprosy-positive rhesus monkeys developed leprosy despite serologic response patterns to M. leprae antigens that usually indicate leprosy resistance. Three (60%) of the five SIV-positive rhesus monkeys developed leprosy compared with 21% of the animals who received SIV-free M. leprae inocula. Diminished lepromin skin test responses and decreasing T-helper cell percentages were observed in SIV-coinoculated rhesus monkeys with leprosy. These observations suggest that SIV increases the susceptibility of rhesus monkeys to leprosy, possibly related to loss of T-helper cell function.
