RESUMO

Os autores, utilizando a técnica da diluição seriada em meio líquido, determinaram as concentrações mínimas inibitórias da ampicüina e da hetacilina em 150 amostras de Salmonella typhi, isoladas em sua totalidade a partir de hemoculturas, no Estado da Guanabara.
Obteve-se como média das concentrações bacteriostáticas, 0,545 mcg/ml para ampicilina e 0,720 mcg/ml, no caso da hetacilina.


SUMMARY

By using serial dilution technique in broth the authors have ãetermined the minimum inhibitory concentration of the 150 strains of Salmonella typhi isolated in their totality from blood cultures in the presenoe of ampicillin and hetacilin.
An average of the bacteriostatic concentration 0,545 mcg/ml for the ampicillin and 0,720 mcg/ml for the hetacilin was obtained.
