    Int J Syst Bacteriol 49:25-35. 1999
    ..Polyamine content was low. G+C content was 72.9 mol%. The new isolates are proposed as a new species, Mycobacterium murale sp. nov. The type strain is MA112/96T (= DSM 44340T)...
  2. pmc Toxigenic strains of Bacillus licheniformis related to food poisoning
    M S Salkinoja-Salonen
    Department of Applied Chemistry and Microbiology, 00231 Helsinki, Finland
    Appl Environ Microbiol 65:4637-45. 1999
    ..When ribotyped with PvuII, most toxin-producing isolates shared bands at 2.8 +/- 0.2, 4.9 +/- 0.3, and 11.7 +/- 0.5 or 13.1 +/- 0.8 kb...
  3. pmc Mutants carrying conditionally lethal mutations in outer membrane genes omsA and firA (ssc) are phenotypically similar, and omsA is allelic to firA
    R Vuorio
    Department of Bacteriology and Immunology, University of Helsinki, Finland
    J Bacteriol 174:7090-7. 1992
    ..All of these findings are consistent with our concept that firA is an essential gene involved in generation of the outer membrane...
