  2. 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 ...

  3. Multidrug-resistant Gram-negative bacteria - Wikipedia

    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 ]

  4. Pseudomonas - Wikipedia

    en.wikipedia.org/wiki/Pseudomonas

    The generic name Pseudomonas created for these organisms was defined in rather vague terms by Walter Migula in 1894 and 1900 as a genus of Gram-negative, rod-shaped, and polar-flagellated bacteria with some sporulating species. [7] [8] The latter statement was later proved incorrect and was due to refractive granules of reserve materials. [9]

  5. Helicobacter pylori - Wikipedia

    en.wikipedia.org/wiki/Helicobacter_pylori

    Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium.Mutants can have a rod or curved rod shape that exhibits less virulence.

  6. Aeromonas - Wikipedia

    en.wikipedia.org/wiki/Aeromonas

    Aeromonas is a genus of Gram-negative, facultative anaerobic, rod-shaped, bacteria that morphologically resemble members of the family Enterobacteriaceae. Most of the 14 described species have been associated with human diseases. The most important pathogens are A. hydrophila, A. caviae, and A. veronii biovar sobria. The organisms are ...

  7. Pseudomonas oryzihabitans - Wikipedia

    en.wikipedia.org/wiki/Pseudomonas_oryzihabitans

    Pseudomonas oryzihabitans is a nonfermenting yellow-pigmented, gram-negative, rod-shaped bacterium that can cause sepsis, peritonitis, endophthalmitis, and bacteremia. [1] It is an opportunistic pathogen of humans and warm-blooded animals that is commonly found in several environmental sources, from soil to rice paddies.

  8. Aeromonas hydrophila - Wikipedia

    en.wikipedia.org/wiki/Aeromonas_hydrophila

    Aeromonas hydrophila is a heterotrophic, Gram-negative, rod-shaped bacterium mainly found in areas with a warm climate. This bacterium can be found in fresh or brackish water. It can survive in aerobic and anaerobic environments, and can digest materials such as gelatin and hemoglobin.

  9. Burkholderia pseudomallei - Wikipedia

    en.wikipedia.org/wiki/Burkholderia_pseudomallei

    Burkholderia pseudomallei [a] (also known as Pseudomonas pseudomallei) is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. [2] It is a soil-dwelling bacterium endemic in tropical and subtropical regions worldwide, particularly in Thailand and northern Australia. [3]
