title: Host-parasite relations in cotton rat filariasis. III. The quantitative transmission of Litomosoides carinii to un-irradiated and irradiated golden hamsters and white mice.
abstract: The quantitative transmission of Litomosoides carinii by Liponyssus bacoti to un-irradiated and irradiated hamsters and mice is described. Both young and adult, un-irradiated and irradiated hamsters were highly susceptible to L. carinii but mice (un-irradiated or irradiated) were poor hosts. All hamsters (18 un-irradiated and seven irradiated) became infected. Seven out of nine mice in an un-irradiated series became infected. There was apparently 'age resistance' or 'young susceptibility' in the hamsters. The susceptibility of young hamsters appeared similar to that of new-born Carworth white rats and cotton rats. The pattern of infection in un-irradiated and irradiated hamsters was similar. Results from irradiated animals were insufficient to draw any clear conclusions on the effect of irradiation to susceptibility to infection with L. carinii. X-irradiation apparently did not affect the innate susceptibility cr resistance of hamsters and mice to worms. The duration and intensity of microfilaraemia was apparently higher in irradiated hamsters.
