Resumo: Haemolytic activity of sixty nine Actinobacillus actinomycetemcomitans strains on different animal and human blood types was examined by using a trypticase soy agar supplemented with yeast extract (0.5%). Blood types used were: rabbit, sheep and human (A, Rh+; A, Rh-; B, Rh+; B, Rh-; O, Rh+; O, Rh-; AB, Rh+; AB, Rh- groups). Plates were inoculated and, incubated in microaerophilic conditions, at 37ºC, for 48 h. The haemolytic activity of the tested strains was characterized as alpha-haemolysis. Only two isolates were not haemolytic on all blood types (2.9%), two strains were haemolytic only on human blood (one strain on AB, Rh+ group and another one on A, Rh+ and AB, Rh+ groups). No specificity between haemolysin produced by the tested strains and blood type was observed.

No specificity between haemolysin produced by the tested strains and blood type was observed. A atividade hemolítica de 69 cepas de Actinobacillus actinomycetemcomitans foi determinada em diferentes tipos de sangue animal e humano, usando como meio base ágar de soja tripticaseina, suplementado com extrato de levedura (0,5%). Foram utilizados sangue de coelho, carneiro e humano (grupos A, Rh+; A, Rh-; B, Rh+; B, Rh-; O, Rh+; O, Rh-; AB, Rh+ e AB, Rh-). As placas foram inoculadas e, incubadas em condições de microaerofilia, a 37ºC, por 48 h. A atividade hemolítica das cepas testadas foi caracterizada como alfa-hemólise. Somente dois (2,9%) isolados não hemolisaram todos os tipos sanguíneos, duas cepas hemolisaram somente sangue humano (uma o grupo AB, Rh+ e outra os grupos A, Rh+ e AB, Rh+). Não foi observada alguma especificidade entre as hemolisinas produzidas e os tipos de sangue utilizados. Universidade de São Paulo.
