  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. Antibiotic sensitivity testing - Wikipedia

    en.wikipedia.org/wiki/Antibiotic_sensitivity_testing

    Antibiotic resistance tests: Bacteria are streaked on dishes with white disks, each impregnated with a different antibiotic. Clear rings, such as those on the left, show that bacteria have not grown—indicating that these bacteria are not resistant. The bacteria on the right are fully resistant to all but two of the seven antibiotics tested. [33]

  4. 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.

  5. 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 ...

  6. Strain (biology) - Wikipedia

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

    The Wistar rat, which was the first developed rat model strain. A laboratory mouse or rat strain is a group of animals that is genetically uniform. Strains are used in laboratory experiments. Mouse strains can be inbred, mutated, or genetically modified, while rat strains are usually inbred. A given inbred rodent population is considered ...

  7. Pathogenic Escherichia coli - Wikipedia

    en.wikipedia.org/wiki/Pathogenic_Escherichia_coli

    E. coli and related bacteria constitute about 0.1% of gut flora, [4] and fecal–oral transmission is the major route through which pathogenic strains of the bacterium cause disease. Cells are able to survive outside the body for only a limited amount of time, which makes them ideal indicator organisms to test environmental samples for fecal ...

  8. Streptococcus mutans - Wikipedia

    en.wikipedia.org/wiki/Streptococcus_mutans

    Different areas of the oral cavity present different ecological niches, and each species has specific properties for colonizing different oral sites. S. mutans is most prevalent on the pits and fissures, constituting 39% of the total streptococci in the oral cavity. Fewer S. mutans bacteria are found on the buccal surface (2–9%). [7]

    For example, the type strain of E. coli (originally strain U5/41) is called ATCC 11775 by the American Type Culture Collection, DSM 30083 by the German Collection of Microorganisms and Cell Cultures, JCM 1649 by the Japan Collection of Microorganisms, and LMG 2092 by the Belgian Coordinated Collections of Microorganisms.
