Abstrakt: Serological investigations on a strain of encephalitis virus isolated from a fatal case in South Australia are described. Evidence is produced that this virus is related to members of the Japanese B. group of viruses, but not identical with any of the previously recognized members. Evidence is given to show that it is identical with the Murray Valley encephalitis virus. Evidence is produced that in the guinea-pig and the horse, complement fixing antibodies to this virus are more rapidly produced than neutralizing antibodies and that in the horse neutralizing antibodies are more enduring than complement fixing antibodies. Field investigations on human and horse sera show twice as many positive neutralization as complement fixation tests. This difference is likely to be due to the more enduring character of the neutralizing antibody. [ABSTRACT FROM AUTHOR]
