The ability of the filarial nematode Loa loa to infect 2 species of primates was studied. The primate species selected were closely related to species known to be susceptible. A mandrill (Mandrillus sphinx) and 6 cynomolgus monkeys (Macaca fascularis) were infected by subcutaneous injection of third-stage larvae of human L. loa from Gabon. The mandrill developed microfilaremia with an estimated prepatent period of 147 days, but microfilariae were not detected in any of the cynomolgus monkeys. Thus, mandrills appear permissive to human L. loa, whereas cynomolgus monkeys are not. Serum antibody responses were examined on western blots of adult L. loa antigens. Preinfection sera from all animals gave no reactions, but, after infection, sera from cynomolgus monkeys reacted more intensely and with more antigens than mandrill sera. Antibodies were still detectable in cynomolgus monkeys 15 mo postinfection. These reactions were compared with those found using human infection sera. Reactions with the cynomolgus monkey sera resembled those found with resistant endemic and amicrofilaremic human sera.
