Twenty-three patients had underlying diseases, in which 15 cases were patients with cancer. Clinically isolated organisms were obtained from 12 cases, of 26 strains were evaluated for bacteriological effects which were eradicated in 10 strains, decreased in 3 and persisted in 13 strains, the eradication rate being 38.5%.
