The report by &erva and Novk concerning 16 human fatalities associated with amoebic meningoencephalitis (1) should ring a warning bell among members of the (health professions. Amoebas are being cultivated with remarkafble frequency from human sources such as the upper respiratory tract and from serum during searches for viruses thou(ght to cause various respiratory symptoms, fevers, and hepati...

Enteroviruses can be easily transmitted through the fecal-oral route and cause a diverse array of clinical manifestations. Recent outbreaks associated with enteroviral contamination in aquatic environments have called for the development of a more efficient and accurate virus monitoring system. To develop a simple, rapid, and direct method for identifying enteroviral infections, we generated a ...

We describe a dramatic presentation of meningoencephalitis, in a young Aboriginal male from Northern Manitoba, due to infection with the Snowshoe hare virus, a member of the California serogroup viruses. Snowshoe hare virus represents a rare cause of meningoencephalitis, and, to date, few Canadian cases have been described in the literature.

Human herpesvirus 6 (HHV-6), the causative agent of exanthema subitum in childhood, can also induce meningoencephalitis in immunocompromised individuals. In contrast, HHV-6 encephalitis in immunocompetent patients is rare, and the clinical syndrome not well defined. We report a case of meningoencephalitis caused by HHV-6 type B in an otherwise healthy woman.

From July 25 to October 1, 1999, 826 patients were admitted to Volgograd Region, Russia, hospitals with acute aseptic meningoencephalitis, meningitis, or fever consistent with arboviral infection. Of 84 cases of meningoencephalitis, 40 were fatal. Fourteen brain specimens were positive in reverse transcriptase-polymerase chain reaction assays, confirming the presence of West Nile/Kunjin virus.

We report 13 cases of Naegleria fowleri primary amebic meningoencephalitis in persons in Karachi, Pakistan, who had no history of aquatic activities. Infection likely occurred through ablution with tap water. An increase in primary amebic meningoencephalitis cases may be attributed to rising temperatures, reduced levels of chlorine in potable water, or deteriorating water distribution systems.

Herpes simplex virus meningoencephalitis (HSV ME) is a severe viral infection that affects the brain and surrounding tissues. It caused primarily by HSV type 1 (HSV-1) virus. This condition requires prompt recognition treatment due to its potential for significant morbidity mortality. We aim highlight importance of avoiding common diagnostic pitfalls in identifying meningoencephalitis, especial...

UNLABELLED Cryptococcosis is caused by the opportunistic pathogen Cryptococcus neoformans or by the primary pathogen Cryptococcus gattii. Epidemiological studies suggest that patients infected with C. gattii mainly present with pulmonary disease, while those infected with C. neoformans commonly manifest meningoencephalitis. We compared the pathogenesis of the two species using the C. neoformans...
