  2. Fluorescence in situ hybridization - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_in_situ...

    FISH can also be used to compare the genomes of two biological species, to deduce evolutionary relationships. A similar hybridization technique is called a zoo blot. Bacterial FISH probes are often primers for the 16s rRNA region. FISH is widely used in the field of microbial ecology, to identify microorganisms.

  3. Bacterial stress response - Wikipedia

    en.wikipedia.org/wiki/Bacterial_stress_response

    Bacteria can survive under diverse environmental conditions and in order to overcome these adverse and changing conditions, bacteria must sense the changes and mount appropriate responses in gene expression and protein activity. The stress response in bacteria involves a complex network of elements that counteracts the external stimulus.

  4. Edwardsiella tarda - Wikipedia

    en.wikipedia.org/wiki/Edwardsiella_tarda

    Edwardsiella tarda is a member of the family Hafniaceae. [1] [2] The bacterium is a facultatively anaerobic, small, motile, gram negative, straight rod with flagella.[1] [2] Infection causes Edwardsiella septicemia (also known as ES, edwardsiellosis, emphysematous putrefactive disease of catfish, fish gangrene, and red disease) in channel catfish, eels, and flounder.

  5. Flow-FISH - Wikipedia

    en.wikipedia.org/wiki/Flow-FISH

    Flow-FISH was first published in 1998 by Rufer et al. [11] as a modification of another technique for analyzing telomere length, Q-FISH, that employs peptide nucleic acid probes [12] of a 3'-CCCTAACCCTAACCCTAA-5' sequence labeled with a fluorescin fluorophore to stain telomeric repeats on prepared metaphase spreads of cells that have been treated with colcemid, hypotonic shock, and fixation to ...

    en.wikipedia.org/wiki/Physical_factors_affecting...

    Bacteria such as Deinococcus radiodurans are particularly resistant to radiation, but are not pathogenic. [1] Active microbes, such as Corynebacterium aquaticum , Pseudomonas putida , Comamonas acidovorans , Gluconobacter cerinus , Micrococcus diversus and Rhodococcus rhodochrous , have been retrieved from spent nuclear fuel storage pools at ...

  7. Bacterial morphological plasticity - Wikipedia

    en.wikipedia.org/wiki/Bacterial_morphological...

    Bacterial morphological plasticity refers to changes in the shape and size that bacterial cells undergo when they encounter stressful environments. Although bacteria have evolved complex molecular strategies to maintain their shape, many are able to alter their shape as a survival strategy in response to protist predators, antibiotics, the immune response, and other threats.

  8. Luria–Delbrück experiment - Wikipedia

    en.wikipedia.org/wiki/Luria–Delbrück_experiment

    The Luria–Delbrück experiment (1943) (also called the Fluctuation Test) demonstrated that in bacteria, genetic mutations arise in the absence of selective pressure rather than being a response to it. Thus, it concluded Darwin's theory of natural selection acting on random mutations applies to bacteria as well as to more complex organisms.

  9. Q-FISH - Wikipedia

    en.wikipedia.org/wiki/Q-FISH

    Quantitative Fluorescent in situ hybridization (Q-FISH) is a cytogenetic technique based on the traditional FISH methodology. In Q-FISH, the technique uses labelled (Cy3 or FITC) synthetic DNA mimics called peptide nucleic acid (PNA) oligonucleotides to quantify target sequences in chromosomal DNA using fluorescent microscopy and analysis software.
