ABSTRACT
Faeces obtained from 1163 children (including 66 newborn babies) were analysed in parallel for the presence of rotavirus particles using two enzyme-linked immunosorbent assay kits. The kits had been formulated by the WHO Collaborating Centre for Reference and Research on Rotavirus (WHO-ELISA kit) and by DAKIPATIS (DAKO-ELISA kit) to be suitable for use in laboratories in developing countries. The kits were evaluated in laboratories in Burma, Chile, India, Mexico, Pakistan, Sri Lanka and the United Kingdom. Comparison of the results obtained with the two kits indicated that the DAKO-ELISA has an overall sensitivity of 97 per cent and a specificity of 97 per cent relative to the WHO-ELISA. In individual laboratories the DAKO-ELISA (K349) kit had a sensitivity in the range 90-100 per cent in assays on faeces obtained from newborn babies. We conclude that the DAKO-ELISA is as sensitive and specific as the WHO-ELISA for the detection of rotavirus antigen in faeces(AU)
