摘要: Abstract : This study was undertaken to determine the optimum harvest time for infected duck embryo cell (DEC) cultures yield highest rickettsial titers and greatest infectivity rhesus monkeys. A consistently reproducible Rocky Mountain spotted fever-infected monkey model pathogenesis studies testing vaccine is produced when inoculum given intravenously contains =1000000 chick median lethal dose organisms. optimally attained with day-4 DEC culture material.
