Resumo: A total of 130 Listeria strains were tested in order to evaluate lecithinase production and capacity for Congo red adsorption as markers of pathogenicity. The strains were identified according to acid production from sugars and by the CAMP test and the data were correlated with the ability to produce keratoconjunctivitis in guinea pigs. L. monocytogenes cultures presented 51.8% and 88.8% positivity rates for Congo red adsorption and lecithinase production, respectively, whereas 80.8% and 100% for L. innocua cultures were negative for the two test, respectively

Estas amostras foram identificadas segundo a produção de ácido a partir de açúcares aliada ao teste CAMP, correlacionando-se estes dados à capacidade de produção de ceratoconjuntivite em cobaio. As culturas de L. monocytogenes apresentaram taxas de positividade para a adsorção do corante e produção de lecitinase de 51,8 e 88,8%, respectivamente, enquanto 80,8% e 100% das culturas de L. innocua foram negativas para os referidos testes.
