Bacteriological observations of the throats of 1, 015 persons were carried out. In this study 370 hospitalized patients (in and outpatients) were tested. They had not been treated using wide-spectrum-antibiotics. The remaining 645 persons were employed as control groups, 78 healthy employees in the medical hospital, (physicians, nurses and etc.) and 567 healthy convicts in The Morioka National Prison.The gram negative bacilli (except Hemophilus) which grow under an aerobic condition, Staphylococcus and Candida were investigated, in reference to the detection rates and resistance to antibiotics and furthermore to the phage-typing of Staphylococcus.Detection rates of the gram negative bacilli and of Staphylococcus were found to be the lowest in the throats of patients. The isolated strains on patient, however, resisted more to multiple antibiotics than those isolated in the throats of the healthy convicts. The throats of healthy hospital employees and those of patients showed similar tendencies. The numbers of gram negative bacilli in the throats of the patients were more numerous than those of the 2 healthy groups.It was epidemiologically significant that Escherichia and Pseudmonas aeruginosa were found in the throats of all groups.Bacteriological investigations of the throat indicated a greater significance than that of the nose, one of the reasons being that gram negative bacilli were not detected in the nasal cavity but in the throat.
