Abstract
Neurologic disease is a major cause of disability in resource-poor countries and a substantial portion of this disease is due to infections of the CNS. A wide variety of emerging and re-emerging viruses contribute to this disease burden. New emerging infections are commonly due to RNA viruses that h...

Abstract
We further describe in this review the capacity of CHIKV to infect neurons and glial cells, delineate the fundamental innate (intrinsic) immune defence mechanisms to protect from infection and argue about the possible mechanisms involved in the encephalopathy.

Abstract
Viral infections of the pediatric central nervous system (CNS) encompass a broad spectrum of both perinatally and postnatally acquired diseases with potentially devastating effects on the developing brain. In children, viral infections have been associated with chronic encephalopathy, encephalitis,...

Abstract
Viral infections of CNS are difficult to diagnose, especially in an early phase. In diagnosis, beside the examination of the cerebrospinal fluid, many other diagnostic tools are used, such a serological tests (in cases with TBE suspicion), PCR (in cases with CMV, VZV, HSV, WNV, enteroviruses infecti...

Abstract
We found: VZV in 13, HSV-1 in 12, EBV in 6, HHV-6 in 4, and HSV-2 in 4. Co-infections of EBV and HSV-2, HSV-1 and HSV-2, HSV-1 and VZV were also disclosed in four cases. In addition, two patients with Guillain-Barré syndrome had HCMV and one showed HHV6 positivity, two patients with myelitis / poly...

Abstract
We have implemented a commercially available PCR-based test for the detection of enteroviral infections. In 2008, we analyzed biological specimens from 125 patients with suspected enteroviral disease, most often involving the nervous system. The presence of enterovirus was detected in 39 patients. T...

Abstract
We used double-stranded RNA (dsRNA), a viral replication intermediate, to mimic the acute phase of viral infection. C57BL/6 mice were injected intraperitoneally with 12 mg/kg of synthetic dsRNA, i.e., polyinosinic-polycytidylic acid (PIC). The treatment induced severe sickness behavior in the animal...

Abstract
The ferret is a standard laboratory animal that can be accommodated in most animal facilities. While not susceptible to measles, ferrets are a natural host of canine distemper virus (CDV), the closely related carnivore morbillivirus. CDV infection in ferrets reproduces all clinical signs associated...

Almost 65 million people worldwide have been infected with HIV since it was first identified in the early 1980s. Neurologic disorders associated with HIV type 1 affect between 40% and 70% of infected individuals. The most significant of these disorders include HIV-associated neurocognitive disorder,...

We used IFN-gammaR1(-/-) mice to examine the target of IFN-gamma in CD8 T cell-mediated demyelination. In IFN-gammaR1(-/-)RAG1(-/-) recipients, demyelination is decreased, but not eliminated, while viral titers are significantly increased when compared to IFN-gammaR1(+/+)RAG1(-/-) recipients. IFN-ga...

Abstract
Many viral infections can involve the central nervous systems (CNS) of fetuses, neonates, infants, and children. The pathogenesis, patterns of CNS involvement, and species of viral infection may differ in the developing fetus, infant and neonate, and early childhood. Familiarity with the clinical co...

Abstract
We retrieved 89 articles reporting on severe CMV infection in 290 immunocompetent adults. Among these reports, the gastrointestinal tract (colitis) and the central nervous system (meningitis, encephalitis, transverse myelitis) were the most frequent sites of severe CMV infection. Manifestations from...

The CVB have long been recognized as significant pathogens of infants and children. Although the major route for transmission of the CVB is fecal-oral, vertical transmission from mother to infant is also possible. This review will focus on the more common or clinically relevant CVB-related syndromes...

Abstract
It is intriguing to note that RABV progression is interrupted neither by destruction of the infected neuron nor by the immune response. Thus, it is likely that RABV has developed a subversive strategy to avoid functional neuron impairment, which compromises the infectious cycle. Rabies virus neuroin...

Abstract
We examined whether the induction of immunosuppressive neuropeptides, in particular CGRP, may contribute to the ability of RABV to evade immune responses. RABV infection of mice caused a strong induction of calcitonin gene-related peptide (CGRP) in neurons and fibres in the neocortex as well as in t...

Abstract
We studied the neuropathology and CNS gene expression patterns in a murine model of rabies using a 'street' isolate RV61. This virus was derived from a human case of disease. In this model, infection of the CNS progresses rapidly following inoculation in the periphery, leading to extensive virus rep...

An outbreak of neurologic EV71 disease occurred in Denver, Colorado, during 2003 and 2005. Likely, EV71 disease remains unrecognized in other parts of the United States, because EV-PCR of cerebrospinal fluid frequently yields negative results. EV-PCR of specimens from the respiratory and gastrointes...
