EXPERIMENTAL TRANSMISSION OF RUSSIAN SPRING-SUMMER ENCEPHALITIS VIRUS BY THE MOSQUITO

Epilepsia partialis continua in tick-borne Russian spring-summer encephalitis.

OBJECTIVES Epilepsia partialis continua (EPC) is characterized by localized continuous jerks, from time to time with spreading Jacksonian seizures and, more rarely, secondarily generalized tonic-clonic seizures. EPC has numerous possible etiologies. In this paper we describe EPC in the tick-borne Russian spring-summer encephalitis (TBRSSE) and compare it with Rasmussen syndrome. METHODS AND M...

Relationship of the Virus of Louping Ill in Sheep and the Virus of Russian Spring-summer Encephalitis in Man

An experimental study of three strains of Russian spring-summer encephalitis virus and one of louping ill virus has yielded the following results:- 1. The sera of mice hyperimmunized to the viruses of Russian encephalitis and louping ill respectively have produced complement fixation with both antigens in almost precisely the same titer. 2. In neutralization tests hyperimmune sera against the R...

Experimental Study on the Transstadial Transmission of Japanese Encephalitis Virus in Mosquito Larvae

Naked DNA vaccines expressing the prM and E genes of Russian spring summer encephalitis virus and Central European encephalitis virus protect mice from homologous and heterologous challenge.

Naked DNA vaccines expressing the prM and E genes of two tick-borne flaviviruses, Russian spring summer encephalitis (RSSE) virus and Central European encephalitis (CEE) virus were evaluated in mice. The vaccines were administered by particle bombardment of DNA-coated gold beads by Accell gene gun inoculation. Two immunizations of 0.5 to 1 microg of RSSE or CEE constructs/dose, delivered at 4-w...

Enduring Immunity following Vaccination of Mice with Formalin-inactivated Virus of Russian Spring-summer (far Eastern, Tick-borne) Encephalitis

A single course of two intraperitoneal injections of formalin-inactivated virus of Russian spring-summer encephalitis induced in albino mice a solidly immune state which endured almost throughout life. Active virus is therefore not essential for the production of a high degree of lasting immunity. The immune response to vaccination consists of resistance to peripherally introduced active virus ...
