STUDY OF THE TULAREMIA PATHOGEN-SIMILAR V. NOVICIDA LARSON ET AL MICROORGANISM
Abstract
Francisella novicida based on its morphological, tinctorial, cultural, and, in particular, pathogenic properties for laboratory animals turned out to be similar to the causative agent of tularemia, which is the basis for combining both microorganisms in one genus. F. novicida decomposed glycerin and contained the enzyme citrullinureidase, which connected this species with the Nearctic and Central Asian variants of the tularemia microbe. F. novicida fermented saccharose and was lyzed relatively slowly in a twine solution, by which it differed from the causative agent of tularemia. In F. novicida the somatic antigenic complex crossed with the corresponding complex of the tularemia microbe. On laboratory animals a live culture of F. novicida did not guarantee protection against repeated infection with lethal doses of a virulent tularemia culture. In the USSR F. novicida can be found primarily in reservoirs - in places of mass congregation of birds, and also on the birds themselves and rodents living with them.
