Human rotavirus (HRV) in faeces of patients may be readily detected with high sensitivity and specificity using latex agglutination (LA) on a glass slide by making use of the cross-reactivity of anti-calf rotavirus (CRV) antibody. Latex particles were coated with anti-CRV immunoglobin. The antibody coated particles (AC-L) are specifically agglutinated by both CRV and HRV, and the agglutination is evident macroscopically within a minute. To examine the sensitivity and reliability of the LA method compared to other methods, HRV in faecal extracts of 48 infants with acute gastroenteritis was sought by the LA, reversed passive haemagglutination (RPHA) and electron microscope (EM) methods. Samples positive by the EM method were all positive by the LA method, and samples negative by EM were all negative by LA. The LA method is suitable for application as a simple clinical diagnostic test.
