Abstract

Enteric adenoviruses (EAd), adenovirus (Ad) types 40 and 41, have been established as causative agents of gastroenteritis.
By electron microscopic (EM) survey of acute gastroenteritis in children in the Matsuyama area, Ad were detected in 275 of 6476 fecal samples obtained from 1980 to 1993. Two-hundredthirteen Ad-positive samples were tested for serotyping by the enzyme-linked immunosorbent assay (ELISA) using three monoclonal antibodies, Ad group-specific, Ad 40 type-specific and Ad41 type-specific antibody. Of 199 samples serotyped by ELISA, 65 were identified as Ad40, 73 as Ad41, 1 as double infection with Ad40 and Ad41, and 60 as Non-EAd. About 70% of Adenovirus detected by EM were suggested to be EAd.
Other epidemiological feature was as follows: EAd were detected throughout the year. The predominant serotype was Ad40 during 1980-1985, while Ad41 were observed after 1986. EAd were detected most frequently from the children aged 0-3 years. The incidence of fever in EAd positive group was lower (30%) than that (67%) in the Non-EAd positive group. The incidence of vomiting, nausea and respiratry symptoms was higher in Ad41 associated infections than Ad40.
