=== '''''OESOPHAGOSTOMUM'' SPECIES''' ===
+
''Oesophagostomum'' is from the superfamily ''Strongyloidea''.  The female is larger than the male at around 2cm in length. The family is characterized by a large buccal capsule, and has leaf crowns surrounding the mouth.
−
*a typical strongyloid
  −
*found in the caecum and colon
  −
*approximately 1.5cm long
  −
*two major species but these are very similar
  −
*a periparturient egg-rise occurs, but this is not as constant as that seen in sheep
  −
*not very pathogenic, but large numbers depress milk production in sows and growth-rate in young pigs.

'''NOTE''': ''[[Hyostrongylus rubidis|H. rubidis]]'' and ''Oesophagostomum'' species both produce typical [[Strongyles|strongyle]] eggs in faeces. ''H. rubidis'' is more pathogenic but produces few eggs, whereas ''Oesophagostomum'' species are prolific egg-layers but not very pathogenic. Care is therefore needed in interpreting egg-count data. Larval culture is needed to confirm presence of ''H. rubidis''.
