Online Photo Atlas in Parasitology Endoparasites in Monogastric Animals
	This practical covers the most common and in many cases, the most pathogenic endoparasites of horses, pigs, dogs, cats and poultry. The adult equine strongyle nematodes belong to the family Strongylidae. All of these inhabit the large intestine, and they are recognized by their relatively large size and features related to their buccal capsule (typical of the superfamily Strongyloidea - in contrast to trichostrongylids of ruminants in which the posterior end is examined). Other equine GIT nematodes are non-bursate, including the large ascarid worm, Parascaris equorum (length up to 45 cm) and the small threadworm, Strongyloides westeri (up to 5 mm), both of which are located in the small intestine. From pigs the three most common nematodes are demonstrated: Ascaris suum, Oesophagostomum spp. and Trichuris suis which are easily recognized by their general appearance. The ascarids of carnivores, Toxocara canis, T. cati and Toxascaris leonina are all relatively large nematodes (adults more than 8 cm) inhabiting the small intestine, They are identified by features of the cervical alae and the tail tip of the male worm. Other small intestinal helminths are hookworms and the common cestode, Dipylidium caninum. Nematodes of the circulatory system (Angiostrongylus vasorum and Dirofilaria immitis) are also important in carnivores, but D. immitis is only seen as imported cases in DK. From poultry only intestinal coccidia (Eimeria spp.) and malaria parasites in blood smears are presented Use the drop-down menu in the top right-hand corner to choose infection..
