  2. Cell damage - Wikipedia

    en.wikipedia.org/wiki/Cell_damage

    Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.

  3. Mycoplasma - Wikipedia

    en.wikipedia.org/wiki/Mycoplasma

    Several Mycoplasma species can cause disease, including M. pneumoniae, which is an important cause of atypical pneumonia (formerly known as "walking pneumonia"), and M. genitalium, which has been associated with pelvic inflammatory diseases. Mycoplasma infections in humans are associated with skin eruptions in 17% of cases. [41]: 293

  4. Necrosis - Wikipedia

    en.wikipedia.org/wiki/Necrosis

    Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always ...

  5. Microbial toxin - Wikipedia

    en.wikipedia.org/wiki/Microbial_toxin

    The mechanism that clostridial toxins follow includes clostridia forming pores and then the pores inserting themselves into the cell membrane of cells. Clostridial toxins have the ability to damage or alter the cell membrane damaging the extracellular matrix of the organism. Toxin A and toxin B are two toxins produced by Clostridioides difficile.

  6. Cell death - Wikipedia

    en.wikipedia.org/wiki/Cell_death

    Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.

  7. Inflammation - Wikipedia

    en.wikipedia.org/wiki/Inflammation

    Membrane attack complex: Complement system: A complex of the complement proteins C5b, C6, C7, C8, and multiple units of C9. The combination and activation of this range of complement proteins forms the membrane attack complex, which is able to insert into bacterial cell walls and causes cell lysis with ensuing bacterial death. Plasmin ...

  8. Protozoan infection - Wikipedia

    en.wikipedia.org/wiki/Protozoan_infection

    P. moriformis causes a disease called protothecosis. This disease mainly infects cattle and dogs. Cattle can be affected by prototheca enteritis and mastitis. [35] Protothecosis is commonly seen in dogs; it enters the body through the mouth or nose and causes infection in the intestines. Treatment with amphotericin B has been reported. [36]

  9. Exotoxin - Wikipedia

    en.wikipedia.org/wiki/Exotoxin

    Membrane-damaging toxins exhibit hemolysin or cytolysin activity in vitro. However, induction of cell lysis may not be the primary function of the toxins during infection. At low concentrations of toxin, more subtle effects such as modulation of host cell signal transduction may be observed in the absence of cell lysis.
