摘要: Between May and August 1975, rotaviruses were detected in the stools of 76 out 174 (44%) newborn babies maternity unit at this hospital. Infection occurred less frequently breast-fed than bottle-fed (P 0.001). However, only 7 (8%) who excreted had symptoms these mild. Complement fixation tests did not show any apparent difference antibody titres or serological responses between mothers rotavirus positive negative babies. When 68 faecal extracts known to contain by electron microscopy inoculated centrifugation on monolayers continuous pig kidney cell cultures (IB-RS-2), antigen was immunofluorescence 65 (95.5%) specimens, 58 being after 3000 g a further 10 000 g. Antigen first 6 hours inoculation maximum levels 24 hours.
