Mineralization of Bacteria [PDF]
Science, 1962 A variety of viable and nonviable bacteria became mineralized with hydroxyapatite when implanted in dialysis bags in the peritoneal cavities of rats. The microscopic pattern of mineral deposition appeared analogous to that in the formation of oral calculus. Since nonviable organisms were mineralized at an accelerated rate, bacterial metabolic processes

msDNAs are small, structurally unique satellite DNAs found in a number of Gram-negative bacteria. Composed of hundreds of copies of single-stranded DNA--hence the name multicopy single-stranded DNA--msDNA is actually a complex of DNA, RNA, and probably protein. These peculiar molecules are synthesized by a reverse transcription mechanism catalyzed by a

There are many infectious agents found within the oral cavity. Bacteria form an important group of micro-organisms found in both healthy and diseased mouths. The current article will discuss those bacteria resident within the mouth and review the oral diseases with which they are associated.

Genetically programmed death of an organism, or phenoptosis, can be found not only in animals and plants, but also in bacteria. Taking into account intrapopulational relations identified in bacteria, it is easy to imagine the importance of phenoptosis in the regulation of a multicellular bacterial community in the real world of its existence.

The Chemistry of Bacteria [PDF]
Annual Review of Biochemistry, 1933 The subject of bacterial multiplication has begun once more to attract investigation. According to Regnier, David & Kaplan the method of the "viable count" may be responsible for serious errors. These workers, using Pseudomonas pyocyanea on a liquid medium, carried out a direct microscopic ("total") count and a "viable" count by the usual method of ...

While traditionally microbiologists have examined bacterial behavior averaged over large populations, increasingly we are becoming aware that bacterial populations can be composed of phenotypically diverse individuals generated by a variety of mechanisms.

BACTERIA may be preserved by drying suspensions either from the frozen or from the liquid state. Of these two methods, the former, particularly in the form of centrifugal freeze drying1, has been widely used because of its efficiency and convenience.

The first extrachromosomal genetic elements discovered in bacteria were temperate bacteriophages, which can exist either as extracellular virus, as chromosomes replicating autonomously within cells or integrated into the bacterial chromosome. Integration of viruses into host chromosomes has subsequently attracted considerable attention by tumor ...
