British and Scabdinavian pigs harbour at least two species of Oesophagostomum: Oe. dentatum and Oe. quadrispinulatum. Sows are more heavily parasitised than are younger age groups. The number of Oesophagostomum in the sow is maximal in the spring, and minimal during the winter months. This seasonal variation is independent of parturition in the host species. During the earlier part of pregnancy no changes of any magnitude are seen in the average numbers of Oesophagostomum eggs shed in the faeces of the sow, although there is a small transient rise at about the nith week. The average egg-count does, however, increase prior to parturition, and this rise continues until a maximum is reached towards the end of lactation. There is an abrupt return to minimal values at weaning. Early weaning shortens the peri-parturient egg-rise. No corresponding fluctuations occur in the egg-counts of boars or non-preganant sows, although in the latter group small peaks have been detected at three wekly intervals in association with the oestrous cycle of the hosr. Post-mortem examination of parturient and non-pregnant sows revealed changes in the fecundity of esophagostomum females during the peri-parturient egg-rise, and that the female members of small populations produced more eggs than did members of larger populations. Female Oesophagostomum from the parturient sows were longer on average than those from the non-pregnant series. The pero-parturient egg-rise can be effectively controlled by means of a single dose of a broad-spectrum anthelmintic given to the sow shortly before parturition. Psychodid flies and rats are capable of introducing infection into worm-free herds.
