Genetic studies on the streptomycin resistance of Mycobacterium avium (strain Jucho) were conducted by the population analysis method assuming a hypothesis that one type of the population structure of first-step clones corresponds to one genotype. The resulting conclusions are as follows:
There are multiple genotypes producing different population structures of clones. Both intermediate and fully resistant population structures of clones are produced by a single gene mutation or by double or multiple mutations.
