Distribui??o temporal de perfis eletrofocéticos de Acido nucleico de rotavírus em fezes de crian?as em Belém, Pará

摘要

Electrophoresis of rotavirus RNA in polyacrylamide gel was casrried out by using faecal samples collected from children living in the peripheral area of Belém, Brazil. Typical rotavirus profiles (eleven bands) were noted in 46(76.7%) out of 60 ELISA rotavirus positive specimens. According to the eletrophoretic patterns, 5(10.9%) were classified as subgroup I, while 41(89.1%) of them as subgroup II. Lacking of bands 10 and 11 in 14(23.3%) samples did not allow us to classify their electropherotypes. The profile coded as "1N2L" was the predominant one, ccouting for 65.2% of the classified strains.
