  2. IMViC - Wikipedia

    en.wikipedia.org/wiki/IMViC

    The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group. A coliform is a gram negative , aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours.

  3. Simmons' citrate agar - Wikipedia

    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]

  4. Enterobacteriaceae - Wikipedia

    en.wikipedia.org/wiki/Enterobacteriaceae

    Enterobacteriaceae is a large family of Gram-negative bacteria. It includes over 30 genera and more than 100 species. It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in ...

  5. Analytical profile index - Wikipedia

    en.wikipedia.org/wiki/Analytical_profile_index

    Before starting a test, one must confirm the cultured bacteria are Enterobacteriaceae, this is done by a quick oxidase test for cytochrome coxidase. Enterobacteriaceae are typically oxidase negative, meaning they either do not use oxygen as an electron acceptor in the electron transport chain , or they use a different cytochrome enzyme for ...

  6. Omptin - Wikipedia

    en.wikipedia.org/wiki/Omptin

    Certain omptins, such as those cutting ArlC and CroP, exhibit high resistance to serum. Within the Enterobacteriaceae family, bacteria produce proteases that can target components of the host's innate immune system. [2] Omptin proteases function as a defense mechanism against antimicrobial peptides and are governed by PhoPQ.

  7. Enterobacterales - Wikipedia

    en.wikipedia.org/wiki/Enterobacterales

    Analyses of genome sequences from Enterobacterales species identified five conserved signature indels (CSIs) for this order in the proteins peptide ABC transporter permease, elongation factor P-like protein YeiP, L-arabinose isomerase, pyrophosphatase, and a hypothetical protein, which in most cases are exclusively shared by either all or most members of this order. [1]

  8. Hafnia (bacterium) - Wikipedia

    en.wikipedia.org/wiki/Hafnia_(bacterium)

    The genus Hafnia is one of more than 40 genera that currently comprise the order Enterobacterales.. Although Møller originally described this genus in 1954, the legitimacy of this group was constantly challenged over the next two decades, often being referred to by synonyms such as "Enterobacter alvei", "Enterobacter aerogenes subsp. hafniae" and "Enterobacter hafniae" but it is mostly ...

  9. Enterobacterial common antigen - Wikipedia

    en.wikipedia.org/wiki/Enterobacterial_common_antigen

    More studies are needed to explain the presence of the antigen in this species as no other strains of this species express the antigen. The ECA is a polysaccharide made of repeating units of trisaccharides. The functions of these units have very few proven functions. Some evidence indicates role in pathogenicity in the bacteria that present the ...
