VIROLOGIC STUDY ON AN OUTBREAK OF INFANTILE DIARRHEA

Adenovirus types 6 and 31 were isolated from an outbreak of epidemic diarrhea in an infant home in late December 1964. Infection of adenovirus type 6 was confirmed by the antibody response. The antibody response to adenovirus type 31 was proved in the sera six months, but not two months, after the infection. Prevalence of adenovirus type 31 among children near Tokyo was confirmed by examination of neutralizing antibody to the virus. The possible association of adenovirus infection with the outbreak of infantile diarrhea is discussed. Some properties of adenovirus type 31 isolates are described. © 1969, National Institute of Infectious Diseases, Japanese Journal of Infectious Diseases Editorial Committee. All rights reserved.
