  2. 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 ]

  3. Gonorrhea - Wikipedia

    en.wikipedia.org/wiki/Gonorrhea

    If Gram-negative, oxidase-positive diplococci are visualized on direct Gram stain of urethral pus (male genital infection), no further testing is needed to establish the diagnosis of gonorrhea infection. [40] [41] However, direct Gram stain of cervical swabs is not useful because the N. gonorrhoeae organisms are less concentrated in these samples.

  4. Bloodstream infection - Wikipedia

    en.wikipedia.org/wiki/Bloodstream_infection

    [21] [22] In general, gram negative bacteria enter the bloodstream from infections in the respiratory tract, genitourinary tract, gastrointestinal tract, or hepatobiliary system. Gram-negative bacteremia occurs more frequently in elderly populations (65 years or older) and is associated with higher morbidity and mortality in this population. [23]

  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 ...

  6. Neisseria gonorrhoeae - Wikipedia

    en.wikipedia.org/wiki/Neisseria_gonorrhoeae

    A Gram stain of a urethral exudate showing typical intracellular Gram-negative diplococci, which is diagnostic for gonococcal urethritis [17]. Neisseria species are fastidious, Gram-negative cocci (though some species are rod-shaped and occur in pairs or short chains) that require nutrient supplementation to grow in laboratory cultures. [18]

  7. Staphylococcal infection - Wikipedia

    en.wikipedia.org/wiki/Staphylococcal_infection

    S. saprophyticus, another coagulase-negative species that is part of the normal vaginal flora, is predominantly implicated in uncomplicated lower genitourinary tract infections in young sexually active women. [9] Other staphylococcal species have been implicated in human infections, notably S. lugdunensis, S. schleiferi, and S. caprae.

  8. Anaerobic infection - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_infection

    Gram-positive spore-forming (Clostridium spp.) and non-spore-forming bacilli (Actinomyces, Propionibacterium, Eubacterium, Lactobacillus and Bifidobacterium spp.); and 4. Gram-negative cocci (mainly Veillonella spp.). The frequency of isolation of anaerobic bacterial strains varies in different infectious sites. [3]

  9. Campylobacter coli - Wikipedia

    en.wikipedia.org/wiki/Campylobacter_coli

    Campylobacter coli is a Gram-negative, microaerophilic, non-endospore-forming, S-shaped bacterial species within genus Campylobacter. [1] In humans, C. coli can cause campylobacteriosis, a diarrhoeal disease which is the most frequently reported foodborne illness in the European Union. [2] C. coli grows slowly with an optimum temperature of 42 ...
