Third-stage larvae of subperiodic Brugia malayi from Aedes togoi or Aedes aegypti (Liverpool strain) were inoculated subcutaneously into the groin of 38 jirds (Meriones unguiculatus). The third molt occurred 7 to 8 days and the final molt 29 to 35 days postinoculation. Male worms molted slightly earlier than females. Early development occurred primarily in subcutaneous and deep connective tissues. Adult worms were found mainly in the testes but also occurred in the heart and lungs. Patent infections were seen in 13 of 19 jirds infected longer than 70 days. The mean prepatent period was 93 days, with a range of 79 to 116 days. Microfilaremias were followed for 5 to 26 weeks; densities did not exceed 65 microfilariae per 20 mm3. Meriones libycus, Neotoma lepida, Dipodomys merriami, and golden hamsters were also inoculated; patent infections were produced in 4 hamsters. Four of 5 M. unguiculatus developed patent infections when given larvae from mosquitoes fed on infected jirds.
