Helminths of Scottish Pigs: Occurrence, Age Incidences and Seasonal Variations

Abstract

The presence of five nematodes previously unknown in the British pig population is reported i.e.Globocephalus urosubulatus,Oesophagostomum quadrispinulatumand three species ofTrichostrongylus.T. vitrinusis recorded for the first time fromSus scrofa domestica. The gastro-intestinal strongylates were encountered most frequently in older animals and were especially numerous in the spring and early summer, whilst the incidence ofAscaris suumandTrichuris suisdeclined with the increasing age of the host.
