morphologically

Examples of morphologically in the following topics:

• Bacterial Differentiation

  • Several bacteria alter their morphology in response to the types and concentrations of external compounds.
  • Bacterial morphological plasticity refers to evolutionary changes in the shape and size of bacterial cells.
  • As bacteria evolve, morphological changes occur to maintain the consistency of the cell.
  • Nutritional stress can change bacterial morphology.
  • However, it returns to a regular rod-like morphology when adding back these nutrients.

• Morphologically Unusual Proteobacteria

  • The two main groups of morphologically unusual proteobacteria include spirillum and prosthecate bacteria.
  • Two main groups of morphologically unusual proteobacteria include spirillum and prosthecate bacteria.

• General Morphology

  • Viruses display a wide diversity of shapes and sizes, called morphologies.
  • In general, there are five main morphological virus types :
  • The capsid is made from proteins encoded by the viral genome and its shape serves as the basis for morphological distinction.

• Viruses of Archaea

  • The morphology and the genome appear to be unique.
  • Most have head-tail morphologies and linear double-stranded DNA genomes.
  • Other morphologies have also been described including spindle shaped, rod shaped, filamentous, icosahedral, and spherical.
  • Additional morphological types may exist.
  • The morphology and the genome appear to be unique.

• Phenotypic Analysis

  • Bacteria, algae, and fungi have been identified in amber that is 220 million years old, which shows that the morphology of microorganisms has changed little since the Triassic period.
  • Some of the early phylogenetic trees of the prokaryote world were morphology-based.
  • There are some basic differences between Bacteria, Archaea, and Eukaryotes in cell morphology and structure which aid in phenotypic classification and identification:
  • Due to lateral gene transfer, some closely related bacteria can have very different morphologies and metabolisms.
  • Basic morphological differences between bacteria.

• MreB and Determinants of Cell Morphology

• Nongenetic Categories for Medicine and Ecology

  • In medicine, microorganisms are identified by morphology, physiology, and other attributes; in ecology by habitat, energy, and carbon source.
  • Once a pathogenic organism has been isolated, it can be further characterised by its morphology, growth patterns (aerobic or anaerobic), patterns of hemolysis, and staining.
  • Other classifications are determined by the disease caused by the virus or its morphology, neither of which is satisfactory as different viruses can either cause the same disease or look very similar.

• Unclassified and Uncultured Bacteria

  • Because of the existence of lateral gene transfer, some closely related bacteria have very different morphologies and metabolisms.
  • Once a pathogenic organism has been isolated, it can be further characterized by its morphology, by growth patterns such as aerobic or anaerobic growth, by patterns of hemolysis and by staining.

• Magnetosomes

  • The particle morphology of magnetosome crystals varies, but is consistent within cells of a single magnetotactic bacterial species or strain.
  • Three general crystal morphologies have been reported in magnetotactic bacteria on the basis: roughly cuboidal, elongated prismatic (roughly rectangular), and tooth-, bullet-, or arrowhead-shaped.

• Endospores

  • There are variations in endospore morphology .
  • Variations in endospore morphology: (1, 4) central endospore; (2, 3, 5) terminal endospore; (6) lateral endospore.
