今年三月廿五日,发现链霉素的瓦克斯曼博士和另一位加拿大科在家辣夏万礼(Hubert A.Lechavali-er)氏在科学周刊(Science)上发表了一篇报告,宣布他们又发现了一种新的治疗结核病的抗生素,他们给它定名炎Neomycin,我们按照字义应该译为新霉素。新霉素跟链霉素都是得之于同一菌属,都是从土壤里分离出来的。链霉素是从一种灰色链霉菌(Streptom-yces Griseus)的培养液中取得的物质,而新霉素是从另一种链霉菌(Streptomyces Fradiae)的培养液中取得的物质。但是这两种抗生素的化学性质以及对于细菌的作用都不相同,不过新霉素的效力比链霉素好,有些
On March 25th this year, Dr. Waksman, who discovered streptomycin, and another Canadian member, Hubert A. Lechavali-er, published a report on Science, announcing them. A new type of antibiotic for treating tuberculosis was discovered. They named it Neomycin. We should translate it into neomycin according to its meaning. Both neomycin and streptomycin are derived from the same genus and are isolated from the soil. Streptomycin is a substance obtained from a culture of Streptom-yces Griseus, and neomycin is a substance obtained from a culture of Streptomyces Fradiae. However, the chemical properties of these two antibiotics and their effects on bacteria are not the same, but neomycin is more effective than streptomycin.
