Extract
Two events concerned with echo virus 14 infection were reported.
The first, which occurred in Sendai in 1962, was that the intestinal infection with the attenuated poliovirus 1 vaccine was possibly suppressed by naturally occurring infection with echovirus 14. Echovirus 14 was isolated 10 days after the vaccine feeding in six out of nine cases, but poliovirus in only two cases. Six of the vaccinated babies did not exhibit antibody response to the poliovirus 1, while a significant rise of antibody titre against echovirus 14 was seen in as many as eight babies 7 weeks after the vaccination.
The second was a small outbreak of aseptic meningitis due to echovirus 14 in Aomori in 1963. During August to October, echovirus 14 was isolated from the faeces of seven patients with aseptic meningitis. The virus was also isolated from the CSF in one case. The antibody titre against echovirus 14 was detected in all the patients from whom the virus was isolated. In addition, echovirus 14 antibody was detected in four out of fourteen patients with aseptic meningitis from whom no virus was recovered. The onset of serologically positive patients was limited to the months of August to October.
