Resumo
Foram analisadas amostras de água e de dializados coletados de diferentes pontos do sistema de hemodiálise de um Centro de Hemodiálise de um hospital de Campinas, São Paulo, Brasil, após um surto de bacteriemia ocorrido em setembro de 1996. As amostras foram submetidas à contagem de bactérias heterotróficas e pesquisa de coliformes totais, assim como foram realizadas as hemoculturas dos pacientes com bacteriemia. As cepas isoladas e identificadas como Pseudomonas aeruginosa foram submetidas à sorotipagem e à piocinotipagem e, naquelas pertencentes ao mesmo sorotipo e piocinotipo, procurou-se determinar o perfil de sensibilidade aos agentes antimicrobianos e o ribotipo. Quanto à pesquisa de Pseudomonas, 80% das amostras correspondentes à segunda coleta foram positivas e em todas as amostras referentes à terceira coleta foram isoladas Pseudomonas aeruginosa ou Bulkholderia cepacia. Apenas uma cepa de P.aeruginosa de água pertencia aos mesmos sorotipo (O15) e piocinotipo (P10) daqueles obtidos dos pacientes. A compatibilidade genética das amostras das duas origens, verificada pela ribotipagem, sugere um veículo comum na propagação da infecção.
