Antigenic Differences Between Mycobacterium bovis Strain BCG and an Isoniazid-Resistant Mutant.

abstract：:Random minitransposon mutagenesis was used to identify genes involved in the survival of Bordetella bronchiseptica within eukaryotic cells. One of the mutants which exhibited a reduced ability to survive intracellularly harbored a minitransposon insertion in a locus (ris) which displays a high degree of homology to tw...
