• In serotype 4b, gtcA appears to be the first member of a bicistronic operon which includes a gene with homology to Bacillus subtilis rpmE , encoding ribosomal protein L31. (asm.org)
  • In Bacillus subtilis , TAs have been shown to be essential for viability ( 22 , 28 ). (asm.org)
  • The arbitrary primer polymerase chain reaction (AP-PCR) and Southern blot restriction fragment length polymorphism (RFLP) were used to genotype the periodontal pathogen A. actinomycetemcomitans. (upenn.edu)
  • The membrane was probed with a previously characterized 5.2 kilobases (kb) DNA fragment cloned from A. actinomycetemcomitans strain Y4. (upenn.edu)
  • The addition of the Southern blot analysis to the AP-PCR analysis gave rise to a total of 30 DNA profiles among the 73 A. actinomycetemcomitans study strains. (upenn.edu)
  • Of the microflora characterised in aggressive periodontitis, approximately 65-75% of bacteria are Gram-negative bacilli, with few spirochaetes or motile rods present. (wikipedia.org)
  • Phenol in turn is more soluble in waxes and lipids such as those present on tubercle bacilli. (microrao.com)
