St. Louis Encephalitis with Focal Neurological Signs

St. Louis encephalitis with focal neurological signs.

St. Louis encephalitis (SLE) is a form of epidemic encephalitis named for a 1993 outbreak in that Missouri city when 11000 cases occurred; the fatality rate during this epidemic was ∼20% [1]. Although it is the most common type of viral encephalitis, !1% of patients present for medical attention [2]. Symptoms are usually nonspecific and consistent with those of viral meningitis.

St. Louis Encephalitis

Transmission of the virus of St. Louis encephalitis to normal chickens by the bite of infected mites (Dermanyssus gallinae) has been demonstrated. Both experimentally infected and naturally infected mites were shown to be capable of transferring the virus of St. Louis encephalitis to chickens by bite. Virus is present in the blood of such chickens in small amounts, so that demonstration of vire...

Genetic variation of St. Louis encephalitis virus

St. Louis encephalitis virus (SLEV) has been regularly isolated throughout the Americas since 1933. Previous phylogenetic studies involving 62 isolates have defined seven major lineages (I-VII), further divided into 14 clades. In this study, 28 strains isolated in Texas in 1991 and 2001-2003, and three older, previously unsequenced strains from Jamaica and California were sequenced over the env...
