[Parasitologic study of feces: simultaneous performance of Faust's, Janecko-Urbanyi's and Ritchie's concentration...

The authors propose the simultaneous use of Faust's, Janeckso-Urbanyi's and Ritchie's techniques according to a protocol which combines the effectiveness of the three techniques, with a saving in reagents, a significant simplification of the manipulations (a single dilution of the stools, a single straining and a total of three centrifugations) and the possibility of conducting valid comparative studies, as the three techniques are performed from the same faecal aqueous suspension.
