馬鈴薯澱粉加3% KH₂PO₄培地における結核菌の発育成績について

抄録

It has been said that the prominence of Löwenstein-Jensen's medium (L-J) in the culture of tubercle bacilli is essentially based on the potato flour in it. It was reported by Saito et al. that they made a new 3% KH₂PO₄ egg medium with potato flour (AEP), by adding 5% potato flour to Ogawa's medium, and this AEP proved much better than any of Oka-Katakura's, Ogawa's or L-J's medium. We made quantitative cultures of the sputum from 114 tuberculous patients using AEP, Ogawa's and L-J's medium at the same time.
Comparing the results from these pure cultures the following observations were made:
1) AEP was superior than Ogawa's and L-J's medium in the rate of positivity, the growth and the rapidity of the growth of bacilli, and the number of the colonies.
2) In the rate of contamination AEP was a little less desirable than Ogawa's or L-J's medium.
