ABSTRACT
Two direct methods for the diagnosis of trichinellosis were compared: trichinoscopy and artificial digestion. Muscles from 17 wistar rats, orally infected with 500 Trichinela spiralis encysted larvae were examined. From each of the following muscles: diaphragm, tongue, masseters, intercostals, triceps brachialis and cuadriceps femoralis, 648,440 larvae from 1 g samples were recovered. The linear correlation between trichinoscopy and artificial digestion was very high and significant (r=0.94,p<0.0001), showing that both methods for the detection of muscular larvae did not differ significantly. In both methods, significant differences were found in the distribution of larvae per gramme of muscle.

Este trabajo tuvo por finalidad poner la técnica propuesta por la American Public Health Association, la American Water Works Association y la Water Pollution Control Federation, para la detección de parásitos en agua. Se utilizaron filtros de cartucho de polipropileno, de porosidad nominal de 5 *m. La reproducibilidad del método y la eficiencia del filtro, se evaluaron experimentalmente, con concentraciones conocidas de quistes de Giardia Lamblia con un muy buena tasa de recuperación. Sobre un total de 15 muestras de agua de distintas procedencias, se detectaron quistes de Giardia lamblia en una muestra de agua subterránea, de la localidad de City Bell, provincia de Buenos Aires. Se incluyen datos sobre características de los quistes y aspectos epidemiológicos de la giardiasis hídrica
