Abstract
Susceptibility to a cottontail strain of Obeliscoides cuniculi was demonstrated in New Zealand White and Dutch rabbits. Stable infections lasting 4 to 8 months were induced by oral inoculation of 80 to 10,000 larvae in immature or adult rabbits of either sex. A larger infective dose was poorly tolerated and the resulting infection was transient. Immature albino guinea pigs were slightly susceptible to infection, but young albino mice, rats, and golden hamsters were refractory. The prepatent period averaged about 19 days. The mean recovery rate of the total larval dose in immature rabbits was 29.8%, with a male/female ratio of 0.26. Following spontaneous cure, rabbits were susceptible to reinfection. Certain gross biological similarities to ruminant stomach worm infections were noted.Keywords
