[Effect of biopreparations on dynamics of the number of bacteria and phytopathogenic fungi in potato agroecosystem].

Application of biological preparations such as Phytotsid and Planryz favoures the growth of the general number of soil's bacteria population compared with control by 13.0-36.1% in the variant of potato variety Scarbnytsya and by 4.

Structural changes and cellular localization of resuscitation-promoting factor in environmental isolates of Micrococcus luteus.

Dormancy among nonsporulating actinobacteria is now a widely accepted phenomenon. In Micrococcus luteus, the resuscitation of dormant cells is caused by a small secreted protein (resuscitation-promoting factor, or Rpf) that is found in "spent culture medium." Rpf is encoded by a single essential gene in M.

[The follow-up results of patients with necrotic suppurative forms of diabetic foot syndrome].

Follow-up results of 162 patients with necrotic suppurative forms of the diabetic foot syndrome (DFS) are studied in a period of 6 months to 7 years. 51.35% of patients with neuropathic form of DFS (NPDFS) relapsed, whereas among patients with neuroischemic form (NIDFS) relapse was reported in 61.

Attempts to revive Mycobacterium tuberculosis from 300-year-old human mummies.

Environmental persistence of Mycobacterium tuberculosis is subject to speculation. However, the reality that infected postmortem tissues can be a danger to pathologists and embalmers has worrisome implications. A few experimental studies have demonstrated the organism's ability to withstand exposure to embalming fluid and formalin.

Micrococcus luteus -- survival in amber.

A growing body of evidence now supports the isolation of microorganisms from ancient materials. However, questions about the stringency of extraction methods and the genetic relatedness of isolated organisms to their closest living relatives continue to challenge the authenticity of these ancient life forms. Previous studies have successfully isolated a number of spore-forming bacteria from organic and inorganic deposits of considerable age whose survival is explained by their ability to enter suspended animation for extended periods of time.
