摘要: Immune electron microscopy, which can detect hepatitis A antigen and antibody (anti-HA), was used to study a foodhandler-associated outbreak of among 136 naval recruits. In stool specimens collected during the acute phase illness, 27-nm viruslike hapatitis particles were shown, but only in patients with icteric hepatitis. Detection possible stools as early 10 days before peak serum aminotransferase activity up time enzyme activity, not thereafter. The immunologic similarity these those found volunteers inoculated MS-1 strain virus determined, an increase anti-HA shown between convalescent serums from 25 These data support view that is serologically related naturally acquired type
