  2. Bacterial taxonomy - Wikipedia

    en.wikipedia.org/wiki/Bacterial_taxonomy

    Bacterial taxonomy is the classification of strains within the domain Bacteria into hierarchies of similarity. This classification is similar to that of plants , mammals , and other taxonomies. However, biologists specializing in different areas have developed differing taxonomic conventions over time.

  3. Strain (biology) - Wikipedia

    en.wikipedia.org/wiki/Strain_(biology)

    A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized by their differing isoforms of surface proteins.

  4. Escherichia coli in molecular biology - Wikipedia

    en.wikipedia.org/wiki/Escherichia_coli_in...

    Escherichia coli is one of the most diverse bacterial species, with several pathogenic strains with different symptoms and with only 20% of the genome common to all strains. [1] Furthermore, from the evolutionary point of view, the members of genus Shigella ( dysenteriae , flexneri , boydii , sonnei ) are actually E. coli strains "in disguise ...

  5. Pathogenic bacteria - Wikipedia

    en.wikipedia.org/wiki/Pathogenic_bacteria

    Bacteria can ascend into the bladder or kidney and causing cystitis and nephritis. [15] [16] Bacterial gastroenteritis is caused by enteric, pathogenic bacteria. These pathogenic species are usually distinct from the usually harmless bacteria of the normal gut flora. But a different strain of the same species may be pathogenic.

    To change this template's initial visibility, the |state= parameter may be used: {{Infectious disease symptoms and signs | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Infectious disease symptoms and signs | state = expanded}} will show the template expanded, i.e. fully visible.

  7. Pathovar - Wikipedia

    en.wikipedia.org/wiki/Pathovar

    Bacterial black spot of mango caused by Xanthomonas citri pv.mangiferaeindicae. A pathovar is a bacterial strain or set of strains with the same or similar characteristics, that is differentiated at infrasubspecific level from other strains of the same species or subspecies on the basis of distinctive pathogenicity to one or more plant hosts.

  8. Shigella dysenteriae - Wikipedia

    en.wikipedia.org/wiki/Shigella_dysenteriae

    Shigella dysenteriae is a species of the rod-shaped bacterial genus Shigella. [1] Shigella species can cause shigellosis (bacillary dysentery). Shigellae are Gram-negative, non-spore-forming, facultatively anaerobic, nonmotile bacteria. [2] S. dysenteriae has the ability to invade and replicate in various species of epithelial cells and ...

    The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
