A classic example of this effect is the interaction between β-lactams, which damage the bacteria cell membrane, and aminoglycosides, which inhibit protein synthesis. [1] The damage dealt to the cell wall by β-lactams allows more aminoglycoside molecules to be taken up into the cell than would otherwise be possible, enhancing cell damage. [ 1 ]
Microbial synergy is a phenomenon in which aerobic and anaerobic microbes support each other's growth and proliferation. In this process aerobes invade and destroy host tissues, reduce tissue oxygen concentration and redox potential, thus creating favorable conditions for anaerobic growth and proliferation.
In the natural world, synergistic phenomena are ubiquitous, ranging from physics (for example, the different combinations of quarks that produce protons and neutrons) to chemistry (a popular example is water, a compound of hydrogen and oxygen), to the cooperative interactions among the genes in genomes, the division of labor in bacterial ...
Microorganisms, or microbes, span all three domains of life – bacteria, archaea, and many unicellular eukaryotes including some fungi and protists.Typically defined as unicellular life forms that can only be observed with a microscope, microorganisms were the first cellular life forms, and were critical for creating the conditions for the evolution of more complex multicellular forms.
Koch, a pioneer in medical microbiology, worked on cholera, anthrax and tuberculosis. In his research into tuberculosis Koch finally proved the germ theory, for which he received a Nobel Prize in 1905. [5] In Koch's postulates, he set out criteria to test if an organism is the cause of a disease, and these postulates are still used today.
For example, beans may grow up cornstalks as a trellis, while fixing nitrogen in the soil for the corn, a phenomenon that is used in Three Sisters farming. [ 41 ] One researcher has proposed that the key advantage Homo sapiens had over Neanderthals in competing over similar habitats was the former's mutualism with dogs.

Gram stains yield results much more quickly than culturing, and are especially important when infection would make an important difference in the patient's treatment and prognosis; examples are cerebrospinal fluid for meningitis and synovial fluid for septic arthritis.
