Morphology And Arrangement Of Bacteria

Colony Morphology & Identification of Bacteria. The term “colony morphology” refers to the visible characteristics of a colony. Colonies that differ in appearance are typically different bacterial strains, species, or genera.

Bacteria Morphology. Morphology of Neisseria gonorrhoeae Gonorrhea is caused by the bacteria Neisseria gonorrhoeae. Neisseria gonorrhoeae is Gram-negative, which means it does not retain crystal violet dye in the Gram staining test. This also means that the bacteria contains thin peptidoglycan layer right next to its cytoplasmic membrane.

Another clue is that some bacteria can modify their morphology in response to environmental cues or during the course of pathogenesis [e.g., 6], suggesting that shape is important enough to merit regulation. Two evolutionary arguments also support the utility of bacterial shape.

Recent advances in the understanding of DS effects have been achieved based on the evaluation of aboveground (shoot) traits, whereas little information is available about the effects of DS on root.
