摘要:
The relations that exist between the helminths and their hosts cannot be divided into specific groups. Nevertheless, it is desirable that some classification of these relations, together with clear-cut definition of terms, be widely accepted in order that the subject may be discussed intelligibly. A tentative classification is suggested, which distinguishes between (i) compatibility and incompatibility, which refer only to the host environment as it exists before invasion by the parasite; (ii) resistance, of various kinds and degrees, which refers to the reaction of the environment to thepresenceof the helminth; and (iii) tolerance and intolerance, which refer to the reaction of the environment to theeffectsof the helminth.

摘要:
All the helminths found in the domestic pigeon are reviewed and notes on their distribution location in the host, and pathogenicity are given. Three helminths,Ascaridia columbae,Capillaria columbaeandEchinostoma paraulum, have been found in Canadian pigeons and described,Echinostoma paraulumbeing recorded for the first time in North America. The lip characteristics ofAscaridia columbae, which until now have been little studied, are described in detail.
