Abstract:

Streptomycin-sensitive cultures of Pasteurella novicida can be transformed by deoxyribonucleic acid DNA extracted from streptomycin-resistant cultures of P. novicida or P. tularensis. Similarly, cultures nutritionally dependent on tryptophan or adenine for growth can be transformed to nutritional independence for these requirements by DNA carrying the appropriate allele from P. novicida or P. tularensis. The formation of hybrid recombinants establishes the close genetic relatedness of P. novicida and P. tularensis, but the reduced frequency of transformation observed when P. tularensis serves as the donor suggests significant differences at the molecular level. The ability of P. novicida to undergo transformation, i.e., become competent, is not restricted to a short phase of the growth cycle, but is present uniformly throughout the logarithmic and early stationary phase of growth.
