[Massive use of coproparasitoscopy with a phenol-alcohol-formaldehyde fixing solution]. / Uso masivo de la coproparasitoscopía con FAF.

The use of a fixing solution (FAF) to preserve parasite specimens in routine coproparasitoscopy is considered in this paper as an essential tool in surveys and field work aimed at diagnosing intestinal parasitic disease. It increases the reliability of the analysis procedure when the samples have to be transported over long distances to a central laboratory.
