Abstract

The susceptibility of eighty F. nucleatum isolates from periodontal patients, healthy subjects and Cebus apella monkeys to human pooled sera was tested. The resistance to serum bactericidal effects was observed in 46.9% of the isolates from periodontal patients, 28.6% of the healthy subjects and 40% of the monkeys. These results support the hypothesis that serum plays an ecological role by controlling the microbial population inside either the gingival crevice or periodontal pocket.Foi avaliada a susceptibilidade de oitenta isolados de F. nucleatum obtidos de pacientes com doença periodontal, indivíduos sadios e Cebus apella (macaco-prego) frente ao soro humano. A resistência à atividade bactericida do soro foi observada em 46,9% das fusobactérias isoladas de pacientes com doença periodontal, 28,6% das obtidas de indivíduos sadios e em 40% das fusobactérias de primatas não humanos. Esses resultados suportam o conceito de que o soro possui um papel ecológico em controlar a população microbiana no interior do sulco gengival ou bolsa periodontal.
