摘要: Of 92 drug-resistant Mycobacterium tuberculosis strains isolated from sputum specimens, 86 showed growth in two types of 7H12 broth, one with egg yolk and the other without yolk. In addition, grew only plain broth yolk, four others were recovered medium supplemented The radiometrically detected was higher presence corresponding to a number CFU per milliliter these cultures. improvement most noticeable cultures specimens having low acid-fast bacilli smear producing few colonies on solid media.
