    en.wikipedia.org/wiki/Gram_stain

    Gram negative Neisseria gonorrhoeae and pus cells. Gram-negative bacteria generally possess a thin layer of peptidoglycan between two membranes (diderm). [26] Lipopolysaccharide (LPS) is the most abundant antigen on the cell surface of most gram-negative bacteria, contributing up to 80% of the outer membrane of E. coli and Salmonella. [27]

    en.wikipedia.org/wiki/Multidrug-resistant_gram...

    Multidrug resistant Gram-negative bacteria (MDRGN bacteria) are a type of Gram-negative bacteria with resistance to multiple antibiotics. They can cause bacteria infections that pose a serious and rapidly emerging threat for hospitalized patients and especially patients in intensive care units . [ 1 ]

  5. 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/Simmons'_citrate_agar

    Simmons' citrate agar (not planted yet) Simmons' citrate agar is used for differentiating gram-negative bacteria on the basis of citrate utilization, [1] especially for distinguishing Gammaproteobacteria of the family Enterobacteriaceae or even between species of the same genus. [2]

  7. Eosin methylene blue - Wikipedia

    en.wikipedia.org/wiki/Eosin_methylene_blue

    Eosin methylene blue (EMB, also known as "Levine's formulation") is a selective and differential media used for the identification of Gram-negative bacteria, [1] specifically the Enterobacteriaceae. EMB inhibits the growth of most Gram-positive bacteria. EMB is often used to confirm the presence of coliforms in a sample.

  8. Burkholderia gladioli - Wikipedia

    en.wikipedia.org/wiki/Burkholderia_gladioli

    Burkholderia gladioli is a species of aerobic gram-negative rod-shaped bacteria [1] that causes disease in both humans and plants. It can also live in symbiosis with plants and fungi [2] and is found in soil, water, the rhizosphere, and in the microbiome of many animals.

  9. Bartonella henselae - Wikipedia

    en.wikipedia.org/wiki/Bartonella_henselae

    Bartonella henselae is a Gram-negative rod. [6] [7] It can be cultured in a lysis-centrifugation blood culture. [8] The presence of bacteria can be detected by Warthin-Starry stain, or by a similar silver stain technique performed on infected tissue. A pan-Bartonella PCR detection is non-invasive and uses blood or biopsies to diagnose. [9]
