Effect of Harvest Time of Rickettsia rickettsii from Duck Embryo Cell Cultures on Rocky Mountain Spotted Fever Infection in the Rhesus Monkey.
Abstract
This study was undertaken to determine the optimum harvest time for infected duck embryo cell (DEC) cultures to yield the highest rickettsial titers and greatest infectivity for rhesus monkeys. A consistently reproducible Rocky Mountain spotted fever-infected monkey model for pathogenesis studies and testing vaccine is produced when the inoculum given intravenously contains >=1000000 chick embryo median lethal dose organisms. This is optimally attained with day-4 DEC culture harvest material. (Author)
