=== '''''HYOSTRONGYLUS RUBIDIS''''' ===
''H. rubidis'' is very similar to ''Ostertagia'' (which does not occur in pigs) in appearance, life-cycle, epidemiology and pathogenesis, but pigs do not develop any useful immunity.
*a typical trichostrongyloid
*found on the glandular part of the stomach
*seen only in '''outdoor pigs''' (as its fecundity is too low to maintain its life-cycle when faeces are regularly removed from buildings)
*was becoming rare in the UK but likely to increase in prevalence with the trend towards free-range husbandry
*can cause severe weight loss and even death in lactating sows.
