    Structure b represents diplococcus bacteria. Diplococci are pairs of cocci. Examples of gram-negative diplococci are Neisseria spp. and Moraxella catarrhalis. Examples of gram-positive diplococci are Streptococcus pneumoniae and Enterococcus spp. [10] [11] Presumably, diplococcus has been implicated in encephalitis lethargica. [12]

  3. Gram-negative bacteria - Wikipedia

    en.wikipedia.org/wiki/Gram-negative_bacteria

    Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1] Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic ) membrane and an outer ...

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Gram-negative and mycobacteria have an inner and outer bacteria membrane. As a phospholipid bilayer , the lipid portion of the bacterial outer membrane is impermeable to charged molecules. However, channels called porins are present in the outer membrane that allow for passive transport of many ions , sugars and amino acids across the outer ...

  7. Bacterial morphological plasticity - Wikipedia

    en.wikipedia.org/wiki/Bacterial_morphological...

    Bacterial morphological plasticity refers to changes in the shape and size that bacterial cells undergo when they encounter stressful environments. Although bacteria have evolved complex molecular strategies to maintain their shape, many are able to alter their shape as a survival strategy in response to protist predators, antibiotics, the immune response, and other threats.

    A spirochaete (/ ˈ s p aɪ r oʊ ˌ k iː t /) [4] or spirochete is a member of the phylum Spirochaetota (also called Spirochaetes [5] / ˌ s p aɪ r oʊ ˈ k iː t iː z /), which contains distinctive diderm (double-membrane) Gram-negative bacteria, most of which have long, helically coiled (corkscrew-shaped or spiraled, hence the name) cells ...
