Abstract

A eficácia de 28 desinfetantes individuais ou combinados sobre cepas de Salmonella enterica serovar Enteritidis e Escherichia coli foi determinada. Um teste in vitro em presença e ausência de soro como fonte de matéria orgânica foi realizado. Iodopovidona (contendo 1% de iodo ativo), permanganato de potássio a 1%, etanol a 70%, digliconato de clorexidina e três formulações comerciais, baseadas em compostos de amônia quaternária + formaldeído ou em derivados de cresóis, foram mais eficazes contra as cepas bacterianas testadas, reduzindo em mais 106 vezes (6-log) a contagem bacteriana, independente da presença de matéria orgânica. Esses compostos comerciais, bem como o etanol e a clorexidina entre as substâncias químicas individuais avaliadas, podem ser úteis para a implementação de medidas de controle ambiental contra estas duas enterobacterias de importância para a indústria aviária.
