Abstract | A possibilidade de ocorrência simultânea de Staphylococcus aureus no nariz, boca, mãos e fezes foi verificada em 112 indivíduos assintomáticos, residentes na cidade de São Paulo, SP, Brasil. De 40 (35,7%) deles a bactéria em questão foi isolada de, pelo menos, um dos nichos estudados. Entre estes portadores, 27 (67,5%) foram positivos em apenas um dos quatro nichos, 8 (20,0%) em dois e 5 (12,5%) em três. Das 113 cepas de S. aureus identificadas, 28 (24,8%) isoladas de 9 (22,5%) dos portadores revelaram-se tox +. Entre essas cepas, 7 (25,0%) produziram enterotoxina do tipo A, 6 (21,4%) do tipo B, 11 (39,3%) do tipo C e 4 (14,3%) dos tipos A e C simultaneamente. A fagotipagem revelou a predominância de cepas sensíveis aos fagos do Grupo I/III/NC (16,8%) . Os resultados obtidos não demonstraram a ocorrência simultânea de cepas de Staphylococcus aureus em amostras colhidas de boca, mãos e fezes do grupo estudado.One hundred and twelve asymptomatic individuals were analysed with regard to the simultaneous incidence of Staphylococcus aureus on their hands and in their nose, mouth and stools, in the city of S. Paulo (Brazil). A total of 40 (35.7%) individuals were detected as carriers of this microorganism. Among these carriers, 27 (67.5%) were positive in only one of the four niches studied, 8 (20.0%) in two and 5 (12.5%) in three niches. They were identified 113 Staphylococcus aureus strains, and 28 (24.8%) of these strains, isolated from 9 (22.5%) carriers, produced enterotoxin. Of these strains, 7 (25.0%) produced type A enterotoxin, 6 (21.4%) of type B, 11 (39.3%) type C and 4 (14.3%) produced both type A and C. The phage typing of the 113 Staphylococcus aureus strains revealed the predominance of the strains lysed by phages belonging to the Group I/III/NC (16.8%). The results obtained did not demonstrate the simultaneous incidence of Staphylococcus aureus strains in samples collected from mouth, hands and stools of the group studied. |
