An analysis of the course of infection of Moniliformis dubius (Acanthocephala) in rats

An analysis of the course of infection of mixed oral infections of 12 cystacanths of Moniliformis dubius in 174 male and 179 female Wistar rats has been undertaken. There was a marked decline in the average recovery rate of worms of both sexes from hosts of both sexes during the course of the infection. Female worms from both male and female rats showed, on average, a greater power of survival than male worms from the third period (10–13 weeks) onwards. Male rats were found to retain, on average, a greater number of worms of both sexes than female rats. We wish to thank Miss Susan Arnold and Mr David Barnard for excellent technical help.
