%X a technique to recovery t. canis eggs from soil samples described in hannover, germany, was adapted to local conditions in valdivia, chile, and it was necessary to test its efficiency. 160 £¿trumao type£¿ soil samples of 25 g were prepared adding 354.4 ¡À 61 eggs oft. canis contained in 0.1 ml of a water suspension. in the adaptation process of the technique, it was prove three variables making 20 repetitions of the following combinations: a) detergent added: acid anionic (ph 4.6), or basic anionic (ph 11.5). b) flotation solution used: sugar solution (density: 1.25), or saturated zinc sulphate (density: 1.38). c) with or without mechanical mixing of the samples previous to the flotation process. the best result, of an average of 50.9% (p < 0.05) of the recovered added t. canis eggs from 25g of £¿trumao type£¿ soil was obtained with the addition of acid anionic detergent to the samples, the use of a saturated zinc sulphate solution for the flotation of the eggs and mixing the samples before each flotation process
