RESUMEN
The pattern of spatial disposition of eggs of the parasites (Ascaris lumbricoides, Trichuris trichiura and Ancylostomidae) into the faeces was found overdispersed, independently of the technique of prodiagnosis used (Direct smear without standarisation, Stoll, Shore & Lynch, Kato-Katz and Mc Master). Therefore, differences were not detected in the interpretation of the results among the techniques at the population level, in quantitative studies. In an overdispersed pattern, only few hosts are the major responsibles for the environmental contamination. The importance of this spatial arrangement for parasite control purposes, is discussed
