The Use of Streptomycin in the Cultivation of Endameba Histolytica from Stools

The use of streptomycin in doses varying from 1.0 to 10.0 mgms. per ml. of serum-saline overlay increased the percentage of positive cultures of trophozoites obtained from stools containing cysts of E. histolytica from 8 per cent in the controls to 73 per cent. The use of the drug produced varying degrees of bacterial inhibition, retarded the decomposition of the rice starch and suppressed B. hominis.
