“…In addition to causing outbreaks, aseptic meningitis can present as sporadic cases (SC), keeping active the circulation of the viral serotypes involved in these cases [Thoelen et al, 2003;Kmetzsch et al, 2006;Grenón et al, 2008;Mirand et al, 2008;Tavakoli et al, 2008;Papa et al, 2009]. Detection and typing of the enterovirus involved in clinical disorders is valuable in relating the serotypes to these diseases and contributes to their surveillance [Tavakoli et al, 2008].…”

Aseptic meningitis is one of the most common neurological disorders caused by enteroviruses. Among them, Echovirus 30 (E30) is described as the main etiological agent of many outbreaks and sporadic cases. This study investigated the genomic variability of E30 isolated from the cerebrospinal fluid (CSF) of aseptic meningitis cases that occurred from 1998 to 2008 in Brazil. Over a 10-year period (1998-2008), 302 non-polio enteroviruses were isolated, of which 177 were identified as E30 (58.6%). Phylogenetic analysis of the complete VP1 gene (876 nt) of 48 E30 isolates was performed and compared with additional Brazilian and foreign strains. E30 VP1 sequences segregated into three distinct major groups and seven subgroups, which were linked to the isolation year. In general, sequence divergence among E30 strains ranged from 0.2% to 13.8%. A common direct ancestor for this set of E30 strains was not defined. Brazilian isolates from Group I were related genetically to a 1997 USA isolate and both may have a common origin. Group III representatives showed close relationship to the 2007 Argentinean isolates. The present results complement existing data on the molecular characterization and genetic variability of E30 and may contribute to the understanding of the epidemiology of aseptic meningitis in the region.

“…[1][2][3][4][5] No Brasil, os enterovírus também são os principais responsáveis pela meningite viral. 6 O comportamento epidêmico não é só observado no Recife, senão também em outras cidades brasileiras 7,[16][17][18][19][20] e países do mundo, 3,5,[8][9][10][11][12] incluindo os mais desenvolvidos. As duas epidemias detectadas foram diferentes, tanto no que se refere à magnitude quanto no delineamento das curvas.…”

Enteroviruses are the main etiologic agents involved in outbreaks and sporadic cases of aseptic meningitis. Viral isolation in permissive cells is a traditional method for diagnosis, but it is time consuming and may be unsuccessful due to low viral titers and because some enteroviruses do not replicate in routine cell cultures. Therefore, molecular techniques are increasingly being used for detection of these agents. In the present work, 267 cerebrospinal fluid (CSF) samples from aseptic meningitis and meningoencephalitis cases, received between 2008 and 2009, were tested by RT-PCR. These clinical samples were previously negative for virus isolation in cell culture. Enterovirus genome was detected in 59 CSF samples (22.1%) and identification was confirmed by partial nucleotide sequencing. Some demographics of the patients included in the study were analyzed. Direct detection of enterovirus genome from CSF is appropriate to increase sensitivity in aseptic meningitis and meningoencephalitis cases.
