  2. Gram stain - Wikipedia

    en.wikipedia.org/wiki/Gram_stain

    Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]

    The staining method later played a major role in classifying bacteria. Gram was a modest man, and in his initial publication he remarked, "I have therefore published the method, although I am aware that as yet it is very defective and imperfect; but it is hoped that also in the hands of other investigators it will turn out to be useful." A Gram ...

    The pink blobs are vaginal epithelial cells and the dark granules are common artefacts of the Gram-stain. (Note: microscope lenses do not have F-numbers they have Numerical apertures, this one was NA 1.25 and oil immersion).

  5. Listeria ivanovii - Wikipedia

    en.wikipedia.org/wiki/Listeria_ivanovii

    The listeria are rod-shaped bacteria, do not produce spores, and become positively stained when subjected to Gram staining. [1] Of the six bacteria species within the genus, L. ivanovii is one of the two pathogenic species (the other being L. monocytogenes). [2] In 1955 Bulgaria, the first known isolation of this species was found from sheep. [3]

    en.wikipedia.org/wiki/Isolation_(microbiology)

    Gram-negative bacteria will stain a pink color due to the thin layer of peptidoglycan. If a bacteria stains purple, due to the thick layer of peptidoglycan, the bacteria is a gram-positive bacteria. [4] In clinical microbiology numerous other staining techniques for particular organisms are used (acid fast bacterial stain for mycobacteria).

  7. Nugent score - Wikipedia

    en.wikipedia.org/wiki/Nugent_score

    The Nugent Score is a Gram stain scoring system for vaginal swabs to diagnose bacterial vaginosis (BV).The Nugent score is calculated by assessing for the presence of large Gram-positive rods (Lactobacillus morphotypes; decrease in Lactobacillus scored as 0 to 4), small Gram-variable rods (Gardnerella vaginalis morphotypes; scored as 0 to 4), and curved Gram-variable rods (Mobiluncus spp ...

    en.wikipedia.org/wiki/Pseudomonadota

    Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. [10] Currently, they are considered the predominant phylum within the realm of bacteria. [ 11 ] They are naturally found as pathogenic and free-living (non- parasitic ) genera. [ 11 ]

  9. Stenotrophomonas - Wikipedia

    en.wikipedia.org/wiki/Stenotrophomonas

    Stenotrophomonas is a genus of Gram-negative bacteria, [2] comprising at least twenty-six species. The main reservoirs of Stenotrophomonas are soil and plants. [ 3 ] Stenotrophomonas species range from common soil organisms ( S. nitritireducens ) to opportunistic human pathogens ( S. maltophilia ); the molecular taxonomy of the genus is still ...
