Surveillance epidemiological: parvovirus B19 genotype 1

O parvovirus humano B19 foi isolado e caracterizado de amostra clinica de um paciente, infectado no Japao, e que apresentou os sintomas de febre e erupcao cutânea apos sua chegada ao Brasil. A infeccao por parvovirus foi confirmada por meio de seguintes ensaios: Elisa para deteccao de anticorpos IgM antiparvovirus B19 e tecnica de polymerase chain reaction (PCR). Um fragmento da regiao NS1-VP1 foi diretamente submetido ao sequenciamento do nucleotideo. A analise filogenetica parcial do B19, frente as varias sequencias disponiveis no GenBank, indicou que PV B19 isolado correspondeu ao genotipo 1. Human parvovirus B19 was identified and characterized in sample collected from a patient who was infected in Japan, and the symptoms as fever and rash appeared after arriving to Brazil. The occurrence of virus infection was confirmed by both assays: Elisa parvovirus B19-specific IgM antibody detection andpolymerase chain reaction (PCR). A fragment of NS1-VP1 region was directly submitted to nucleotide sequencing. Partial phylogenetic analysis of B19 sequences, including several sequences available in GenBank, indicated that the isolated HPV B19 corresponded to genotype 1.
