Infantile gastroenteritis caused by rotavirus: comparison of enzyme-linked immunosorbent assay and electron microscopy for rapid diagnosis
Abstract
ELISA and negative contrast EM have used for the detection of rotavirus in one hundred stools from children, less than two years old, hospitalized for acute gastro-enteritis during the winter 1977-78. Samples obtained from the same children some months after hospitalization were also tested. A good correlation was found between the results given by EM and ELISA, but the later technique turned out to be more sensitive (12% more positive using ELISA). A rotavirus infection could be demonstrated in 73% of the patients. In the stools of 3 children we found a second virus in association with the rotavirus, and in two cases a pathogenic bacterium. When a second serum specimen was available from children previously infected by rotavirus it was always possible to detect a significant increase in CF antibodies. Several months after hospitalization a 2nd survey indicated that the rotavirus was no longer present but calicivirus, echovirus, coxsackievirus and adenovirus could be detected in those asymptomatic children.
