V Mayer, and J Pogády, and M Starek, and J Hrbka

The clinical and immunological events in volunteers following administration of 5 and 6 dex newborn mouse intracerebral LD5O (NmicLD5O) of the E5 "14" virus clone, segregated from the Langat TP21 E5 strain (tick-borne encephalitis-TE-complex) and propagated in 7 days old SPF chick embryos, are reported. The experimental vaccine, containing the cloned virus, carrying a set of genetic markers of an ic(+) sc s(+/-) t e u (s) N character, caused in volunteers no clinically recognizable effects, but elicited an immune response in them, as determined in PS-cell culture neutralization tests with various TE (western and eastern subtype) strains. In all vaccines, given the virus intramuscularly, seroconversions from negativity to positivity were observed, with antibody titres ranging from 4-128. The parenteral virus administration was superior to the oral route.

D004669	Encephalitis Viruses, Tick-Borne	A subgroup of the genus FLAVIVIRUS that causes encephalitis and hemorrhagic fevers and is found in eastern and western Europe and the former Soviet Union.

D004675	Encephalitis, Tick-Borne	Encephalitis caused by neurotropic viruses that are transmitted via the bite of TICKS. In Europe, the diseases are caused by ENCEPHALITIS VIRUSES, TICK-BORNE, which give rise to Russian spring-summer encephalitis, central European encephalitis, louping ill encephalitis, and related disorders. Powassan encephalitis occurs in North America and Russia and is caused by the Powassan virus. ASEPTIC MENINGITIS and rarely encephalitis may complicate COLORADO TICK FEVER which is endemic to mountainous regions of the western United States.
