| observations on the clinical manifestations and treatment of an experimental infection with brugia malayi in man. | this paper reports clinical observations made during experimental brugia malayi infection in man. this was induced by 52 infective larvae-carrying mosquitoes, anopheles sinensis. a monkey, maccaca mulatta, was inoculated with infective larvae from the mosquitoes infected with nocturnally periodic type of b. malayi from patients. six months later, the monkey became a microfilaria carrier. nine days later, the subject was experimentally bitten by mosquitoes infected from biting the monkey, with an ... | 1989 | 2565406 |
