Abstract

Human enteroviruses are associated with various clinical syndromes from minor febrile illness to severe, potentially fatal conditions like aseptic meningitis, paralysis, myocarditis, and neonatal enteroviral sepsis. Between June 2000 and August 2008 echovirus (E) type 2, 4, 6, 7, 9, 11, 13, 25, 30, coxsackievirus (CV) -A16, -A19, -B5, and enterovirus 71 (EV71) were reported in Hungary. In this study, 29 previously enterovirus positive samples from 28 patients diagnosed with hand, foot and mouth disease, meningitis and encephalitis, were molecularly typed. The genetic relationships of identified serotypes CV-A16, EV71, and E30 were assessed by direct sequencing of genomic region encoding the capsid protein VP1. The sequences were compared to each other and sequences from other geographical regions possessed in Genbank. The phylogenetic analysis of CV-A16 revealed that the viruses were mostly of Far-Eastern or Asia-Pacific origin. Typing of EV71 showed that one virus from 2000 belonged to genotype C1 and five viruses observed in 2004 and 2005 were identified as genotype C4. The 11 echovirus 30 strains showed homology with those of neighbor European countries. The molecular examination of E30 revealed that three separate lineages circulated in 2000, 2001, and 2004- 2006 in Hungary.
