Hypobiosis of Trichostrongylus tenuis in experimentally infected grey partridges.
Storage of infective larvae (L3) of Trichostrongylus tenuis at +4 degrees C for six weeks before being given as single infections to grey partridges (Perdix perdix) did not increase the proportion of worms subsequently found to be hypobiotic. However, after repeated infections, hypobiotic larvae were numerous. Three infections given over three weeks resulted not only in the presence of many hypobiotic larvae, but also in the coincident loss of most adult worms. This indication of the role of immunity in the production of hypobiosis in grey partridges suggests that this species is not a good model for trichostrongylosis in red grouse (Lagopus lagopus scoticus).
