abstract：:A prediction of the hypothesis of Wilson (1977, 1980 a, b) to account for larval migration of homogonic Strongyloides ratti in the host is that the pattern of invasion of the mammary gland of a lactating rat will be quantitatively similar on both sides and independent of the point of entry into the body. Twenty-one su...
