Aseptic Meningitis Caused by Enteroviruses
نویسندگان
چکیده
A broad range of microorganisms cause meningitis; viruses, bacteria, mycobacteria, mycoplasma, spirochetes, fungi, and protozoa have all been identified as causative agents. Some pathogens almost exclusively affect immunocompromised hosts, and some are confined only to endemic areas, but viruses are the most common pathogen worldwide. It is estimated that about 75,000 people in the United States suffer from viral meningitis annually. The annual incidence of bacterial meningitis in the United States is approximately 3 per 100,000 (Tunkel & Sheld, 1993), therefore, viral meningitis is far more common. Although the exact number of cases varies among countries, viral meningitis is the most common meningitis in almost all countries throughout the world.

The Association of Non-polio Enteroviruses with Aseptic Meningitis in Children in Iran
Introduction : Viral meningitis is an inflammation of the leptomeninges as a manifestation of central nervous system (CNS) infection, and more than 85% of viral meningitis cases are caused by non-polio enteroviruses. Molecular methods such as polymerase chain reaction (PCR) are increasingly used to detect and type non-polio enteroviruses. Here, we describe the impact of these viruses on asept...
متن کاملAseptic Meningitis Epidemic during a West Nile Virus Avian Epizootic
While enteroviruses have been the most commonly identified cause of aseptic meningitis in the United States, the role of the emerging, neurotropic West Nile virus (WNV) is not clear. In summer 2001, an aseptic meningitis epidemic occurring in an area of a WNV epizootic in Baltimore, Maryland, was investigated to determine the relative contributions of WNV and enteroviruses. A total of 113 asept...
متن کاملHuman enteroviruses in cerebrospinal fluid of children with suspected aseptic meningitis: A study in northern Iran
Background: Enterovirus (EV) infections are one of the most common causes of aseptic meningitis in pediatrics. To diagnose EV meningitis, virus isolation in cell cultures is often time consuming and lacks sensitivity to be of clinical relevance. This makes the virus culture results difficult to interpret. The rapid detection of EVs in cerebrospinal fluid (CSF) by molecular diagnostic techniques...

Background: Aseptic meningitis is frequently caused by viral agents, particularly human enterovirus. Several methods of Reverse Transcription PCR(RT-PCR) have recently been introduced and modified for better diagnosis of enteroviral infection in meningitis. This study aimed to determine enteroviruses in patients with suspicion of aseptic meningitis using RT-PCR in the West of I...

BACKGROUND Human enteroviruses (HEVs) are common causes of acute meningitis. However, there is limited information about HEV associated with aseptic meningitis in mainland China because it has not been classified as a notifiable disease. OBJECTIVES To characterize the HEVs associated with sporadic aseptic meningitis in China and to analyze their genetic features. STUDY DESIGN Cerebrospinal ...

The syndromes of aseptic meningitis and meningoencephalitis have a varied aetiology. They are most often caused by a virus -in Sweden, so far as we know at present, mostly by parotitis virus, several types of enterovirus (polio, Coxsackie, E.C.H.O.), and tick-borne encephalitis virus. In patients at the Stockholm Hospital for Infectious Diseases different enteroviruses have dominated at differe...
