The grouping characteristics of 29 respiratory syncitial virus (RSV) present in nasopharyngeal cells collectedfrom hospitalized children with bronchiolitis during the 1990RSVseason in Porto Alegre, RS, were analysed. Twenty-two were grouped as belonging to group A and 7 to group B. Cyanosis, oxigen therapy, cough, lenght of hospitalization and atelectasis were observed to be more frequently found within group B infected children. Other clinical signs and symptoms were similarly found in both groups.

Keywords: Respiratory syncytial virus. Bronchiolitis. RSV groups A and B.


Estudos recentes de amostras do vírus respiratório sincicial (VRS) usando anticorpos monoclonais distiguiram duas variantes antigênicas, designadas como grupos A e B. Estes grupos foram estudados em 29 secreções de nasofaringe positivas para o VRS, provenientes de crianças hospitalizadas com bronquiolite durante surto de virose por VRS, em Porto Alegre, em 1990. Destas, 22 foram grupadas como pertencentes ao grupo A e 7 ao grupo B. Alguns achados clínicos como cianose, tosse, uso de oxigênio e dias de hospitalização foram mais freqüentemente observados em crianças infectadas coin o grupo B do VRS. Outros sinais e sintomas clínicos foram similarmente encontrados nos 2 grupos.

Palavras-chave: Vírus respiratório sincicial. Bronquiolite. Grupos A e B de VRS.
