[Experimental evaluation of the degree of detectability of Helminths' eggs in the soil using 2 methods].
Sand and soil were experimentally contaminated with eggs of Ascaris suum and oncospheres of Hymenolepis diminuta in three doses: 500, 3000 and 5000 eggs (oncospheres) per 50 g of the ground. Numbers of recovered eggs were compared with the use of the two following methods: the method of flotation and Spindler's method, modified by Vasilkova and Ivancuk. The ground samples were investigated the following day and on the 14th day after the contamination. The samples were stored in 20 degrees C and in 4 degrees C. The Spindler's modified method turned out to be better for the studies of outdoor samples, because it enabled us to detect eggs in slightly infected samples, and in different temperatures.
