Molecular Analysis of Echovirus 13 Isolates and Aseptic Meningitis, Spain
نویسندگان
چکیده
Echovirus 13 (EV13), considered rare, was reported worldwide in 2000, mostly related to aseptic meningitis outbreaks. In Spain, 135 EV13 isolates were identified. The genetic relationships between 64 representative strains from Spain and other reported isolates from the United States, Germany, Italy, Japan, and Sweden were described by analyzing the partial sequence of the major capsid protein (VP1) gene. The strains from Spain were clearly identified as EV13 (79.5% similarity with the EV13 reference strain) and were grouped phylogenetically into two different clusters (by origination on either the Iberian Peninsula or Canary Islands). Isolates from Germany from 2000 clustered with the Canary Islands group. The isolates from other countries obtained before 2000 were genetically distant. Changes in EV13 coding sequence involved several differences in the C-terminal extreme of the VP1 protein. Part of the neutralizing antigenic site III has been described in this genome region in poliovirus and swine vesicular disease virus.

Aseptic meningitis in Germany associated with echovirus type 13
BACKGROUND Echoviruses are the commonest cause of aseptic meningitis. Echovirus type 13 which has not been isolated in Germany over a long period of time was the predominant enterovirus serotype associated with different local outbreaks of aseptic meningitis in Germany in 2000. METHODS Virus isolation was performed from cerebrospinal fluid and stools. In order to study the genetic relationshi...

Echoviruses constitute one of the major groups of the genus Enterovirus and are associated with illnesses including aseptic meningitis, nonspecific rashes, encephalitis, and myositis (1). Echovirus 13 is an enterovirus that rarely has been detected in the United States, accounting for only 65 of approximately 45,000 enterovirus isolates reported to CDC during 1970-2000. No associated outbreaks ...

We investigated six cases of enterovirus infection in a neonatal unit. The index patient, a 5-day-old boy, was admitted with aseptic meningitis due to echovirus 30 (E30). Secondary infections with E30 occurred in five babies. Comparison of the complete VP1 sequences showed that the isolates recovered from the index patient and his mother were closely related to those recovered from the five bab...

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 ...
