Q. Do bacteria reproduce by spores?
Spore, a reproductive cell capable of developing into a new individual without fusion with another reproductive cell. Spores are agents of asexual reproduction, whereas gametes are agents of sexual reproduction. Spores are produced by bacteria, fungi, algae, and plants.
Q. What is the function of spores in fungi?
Fungal spores are microscopic biological particles that allow fungi to be reproduced, serving a similar purpose to that of seeds in the plant world. Fungi decompose organic waste and are essential for recycling of carbon and minerals in our ecosystem.

Q. What is the purpose of spores?
Spores are single-celled reproductive units produced by many different organisms, including plants, fungi, and bacteria. Spores are primarily used for asexual reproduction, although some bacterial groups use spores to survive harsh conditions.
Q. Why are spores dangerous?
They also may contain significant amounts of mycotoxins. Diseases associated with inhalation of fungal spores include toxic pneumonitis, hypersensitivity pneumonitis, tremors, chronic fatigue syndrome, kidney failure, and cancer.
Q. Why do spores survive heat?
Spores that form in Bacillus type bacteria provide dormancy at high temperature because enzyme proteins change shape as the spore dehydrates.
Q. Will Heat kill spores?
In general, spores are resistant to moist-heat temperatures that are ∼45°C higher than those that inactivate growing cells of the same organism (36). Moist-heat-killed spores often, but not always, have also lost DPA and may have a few core enzymes inactivated and/or denatured (5, 15, 37).
Q. Which of this will kill spores efficiently?
Bacterial endospores, of the type by Bacillus and Clostridium species, are known to be highly resistant to various forms of radiation and other physical and chemical agents. High-intensity ultraviolet light, however, was suspected to overcome such resistance and to kill spores efficiently.
Q. Does bleach kill bacillus spores?
Either 10% bleach or Bleach Rite® is an appropriate choice for daily decontamination of work surfaces due to the ability of these disinfectants to effectively kill a large portion of B. anthracis spores immediately.
Q. How do spores cause disease?
Spores are inhaled and deposited into the lung tissue, where they proceed to germinate and spread through lymph nodes, rapidly causing systemic disease, massive tissue damage, shock and death (14).
