Abstract
Several different media were compared by means of surface viable counts of suspensions, in 0.1% solution of bovine serum albumin, of freshly grown BCG, and of BCG resuspended after freeze-drying. The growth of BCG on oleic acid albumin medium enriched with 5% whole blood was best in three respects: from a given inoculum, the colony count was highest; the colonies became visible soonest; and reached the greatest maximum size. The superiority of this medium was particularly evident with inocula of BCG reconstituted after freeze-drying.Keywords
