Abstract
No literature has been found regarding circumstances of tablewares contaminated by tuberculous patients and tubercle bacilli. Breakfast utensils served in wards for the open tuberculous patients of a sanatorium were washed with sterile physiogical sodium chloride
solution, and the washing solution was prepared by Ohyama's method. The deposit was smeared on Oka's and Katakurr's culture media and its bacterial growth was observed for six weeks.
Results
For this purpose the experiments were conducted five times. Each time the degree of positivity of bacterial growth on the culture media varies, however, the growth was more or less noted, Niacin-tests (BrCN-aniline tests) were performed on the cultivated bacteria of the second generation and each test proved to be positive. For the purpose of making
histopathological study of the internal organs, the inoculation was admistered to guinea pig3. And the typical tuberculous symptoms were always noted.
Conclusion
1. Bacilli cultivated in the washing solution of contaminated tablewares were mycobacteria tuberculosis var, hominis.
2. The washing solution of contaminated tablewares served in wards for open tuberculous patients suggests the mingling of bacteria which can be apparently examined by the culture.
