    Histopathology of a vegetation of bacterial endocarditis, taken from a valve repair, H&E stain. Abnormal growths in the heart associated with endocarditis In medicine, a vegetation is an abnormal growth [ 1 ] named for its similarity to natural vegetation .

  3. Endospore - Wikipedia

    en.wikipedia.org/wiki/Endospore

    An endospore stain of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota.

  4. Clostridium - Wikipedia

    en.wikipedia.org/wiki/Clostridium

    The vegetative cells of clostridia are heat-labile and are killed by short heating at temperatures above 72–75 °C (162–167 °F). The thermal destruction of Clostridium spores requires higher temperatures (above 121.1 °C (250.0 °F), for example in an autoclave ) and longer cooking times (20 min, with a few exceptional cases of more than ...

    Clostridium tetani is a common soil bacterium and the causative agent of tetanus.Vegetative cells of Clostridium tetani are usually rod-shaped and up to 2.5 μm long, but they become enlarged and tennis racket- or drumstick-shaped when forming spores.

  7. Bacillus subtilis - Wikipedia

    en.wikipedia.org/wiki/Bacillus_subtilis

    The wrong decision can be catastrophic: a vegetative cell will die if the conditions are too harsh, while bacteria forming spores in an environment which is conducive to vegetative growth will be out competed. [24] In short, initiation of sporulation is a very tightly regulated network with numerous checkpoints for efficient control. [citation ...

  8. Pathogenic bacteria - Wikipedia

    en.wikipedia.org/wiki/Pathogenic_bacteria

    Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]

    Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota.Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2]
