Abstract
In the present Part, sporadic cases or suggestive cases of Izuminetsu fever and scarlet fever were clinically diagnosed, and the toroat flora thereof were investigated.
The cases dealt with by the present Part were clinically and hematologically diagnosed. The examinations of the throat flora were conducted following the procedures described in the Parts 1 and 2 of the same series. The results were not constant in each of the cases. However, when summarized, α-type Streptococcus group was found in the largest instance followed by Neisseria group, Micrococcus group II, γ-type Streptococcus group, Hemophilus group, Diphtheroid group, and Staphylococcus aureus group was found in less instances.
Among the organisms belonging to β-type Streptococcus group, those corresponding to Type I were relatively few in number. At least, there were no evidence that more organisms of this type are found in the cases of scarlet fever than in those of Izuminetsu fever. The above results disagreed with heretofore published data. Therefore, the present Part made discussions on the cause of this disagreement. The present Part accounted the use of antibiotics and lack of epidemiological ground to it.
At any rate, the authors presumed no basic changes in the mouth flora in these diseases.
The results of the present series of experiments are expected to be summarized in the forthcoming Part 4.
