Strains of the Mycobacterium avium complex (MAC) yield opaque and transparent colonial variants when cultivated in vitro. The transparent variants are more virulent than the opaque for animals, but little is known about the respective roles of these colonial variants in humans. To assess which variant infects humans, various blood fractions from eight patients with MAC bacteremia were plated directly onto 7H10 agar. In cell fractionation studies, all the M. avium complex CFU were associated with leukocytes and none were found free in plasma. All colonies on the primary culture plate exhibited the transparent phenotype. However, during subculture in 7H9 broth or on Lowenstein-Jensen agar, opaque variants appeared in seven of eight strains. I...
