The aetiological contribution of viral agents in the causation of acute diarrhoea was studied prospectively in 915 infants and young children aged 1-35 months. This was a hospital-based study, selection being carried out by proportionate random sampling; 587 matched controls were also investigated simultaneously. Methods of detection included direct electron microscopy, ELISA for rotaviruses an...
The aetiology of acute gastroenteritis was studied in 50 infants and young children. Bacterial pathogens were isolated in 33, enteropathogenic E. coli (EPEC), Salmonella, and Shigella being the commonest isolates. Rotaviruses were detected in the stools of 13 of the cases. All children with gastroenteritis in whom rotavirus was detected were seen during the months July to December. In 30 childr...
In five separate fecal collections spanning three years, group A rotaviruses were detected by enzyme-linked immunosorbent assay in 35 (25%) of 142 specimens obtained from nondiarrheic, hospitalized neonates in Blantyre, Malawi. Molecular characterization of each strain identified, for the first time in neonates, a short electropherotype, genotype P[6], G8 strain type, similar to the dominant, c...
A previous study showed that intergenogroup reassortants of human rotaviruses can persist in nature (R.L. Ward, O. Nakagomi, D.R. Knowlton, M.M. McNeal, T. Nakagomi, J.D. Clemens, D.A. Sack, and G.M. Schiff, J. Virol. 64:3219-3225, 1990), but the mechanisms involved in their formation and selection had not been determined. In this study it was shown that, during cell culture adaptation of rotav...
