ABSTRACT
Two methods for the diagnosis of rotavirus are compared with 120 stool samples from children under two years of age who had been hospitalized in Centro Habana Children's Hospital with a clinical diagnosis of acute diarrheal disease and 30 samples of healthy children of the same age group who served as controls. The methods used were latex agglutination (Rotalex, commercially-available kit from ORION DIAGNOSTIC ESPOO, Finland) and polyacrylamide gel electrophoresis. Electronic microscopy was used to define those cases whose results did not coincide with the previous techniques. Comparison was made based on the sensitivity and specificity, cost and easiness of performance. Rotalex was less specific but more sensitive than electrophoresis in polyacrylamide gel. The latter is less expensive, since reactants are available at a lower price in dollars and have no expiration date, is very useful in epidemiologic and outbreak studies, since it detects subgroups of circulating rotavirus and it is a painstaking technique (1-20 samples in 10 hours). Rotalex is simple, rapid (1-20 samples in 30 minutes) and allows individual determinations; therefore, we consider its application in hospitals is feasible.
