The effect of feeding different numbers of Toxocara canis eggs on patent intestinal infections was studied in 45 ascarid-naive 62--64-day-old pups and 6 adult dogs. Twenty-four of 25 pups fed 10 to 1,000 eggs developed patent intestinal infections, whereas none of the 20 pups fed 10,000 eggs developed patent intestinal infection. Three of 6 presumably ascarid-naive dogs, 7, 10, and 52 months old fed 100 eggs each, developed intestinal infections.
在45只62 - 64日龄未感染蛔虫的幼犬和6只成年犬中，研究了投喂不同数量犬弓首蛔虫卵对肠道显性感染的影响。25只投喂10至1000个卵的幼犬中有24只发生了肠道显性感染，而20只投喂10000个卵的幼犬均未发生肠道显性感染。6只推测未感染蛔虫的犬（分别为7个月、10个月和52个月大），每只投喂100个卵，其中3只发生了肠道感染。
