ABSTRACT

Os enterovirus foram investigados em secrecoes respiratorias coletadas de pacientes com infeccao respiratoria aguda (IRA), durante um periodo de sete anos (1985-1991), dentro de um estudo longitudinal da etiologia das IRAs. Neste estudo foram encontrados todos os virus que sao mais comumente associados com IRA. Entre os virus isolados, os enterovirus foram apenas menos frequentes que virus respiratorio sincicial, adenovirus e influenzavirus. Quarenta e cinco amostras de enterovirus foram isoladas de pacientes com infeccao do trato respiratorio superior ou inferior. Entre estes enterovirus isolados, trinta e uma amostras foram identificadas como poliovirus (n=18) e enterovirus nao polio (n=13) pelo teste de soroneutralizacao. As amostras de poliovirus isoladas foram classificadas como amostras vacinais do tipo 1 e 2. Dos treze enterovirus nao polio, doze foram identificados como echovirus sorotipos 1, 2, 7, 11, 19 e 31 e apenas um foi identificado como coxsackievirus B4
