Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [2] Endospores contain little or no ATP which indicates how ...
Bacterial endospores are resistant to antibiotics, most disinfectants, and physical agents such as radiation, boiling, and drying. The impermeability of the spore coat is thought to be responsible for the endospore's resistance to chemicals. The heat resistance of endospores is due to a variety of factors:
Some bacteria also produce endospores with an exosporium, of which the most commonly studied are Bacillus species, particularly Bacillus cereus and the anthrax-causing bacterium Bacillus anthracis. The exosporium is the portion of the spore that interacts with the environment or host organism, and may contain spore antigens. [1]
The CDC issued a special report "Knowledge and Practices Regarding Safe Household Cleaning and Disinfection for COVID-19 Prevention" due to the increased number of calls to poison centers regarding exposures to cleaners and disinfectants since the onset of the COVID-19 pandemic, concluding that "Public messaging should continue to emphasize ...
Two genera of bacterial pathogens are known to produce endospores: the aerobic Bacillus and anaerobic Clostridium. [7] Dipicolinic acid forms a complex with calcium ions within the endospore core. This complex binds free water molecules, causing dehydration of the spore. As a result, the heat resistance of macromolecules within the core increases.
Infections are generally sensitive to antibiotics designed for this bacteria class, though complicated by inducible resistance mechanisms, [5] particularly lactamase; infections accordingly become quickly resistant to standard antibiotics during treatment, necessitating a change in antibiotic to avoid worsening of the sepsis.
The usual active lifestyle can change and the bacteria can remain in intracellular vacuoles entering into a slow non-growing state of persistence thus promoting their survival from antibiotics. [12] Fungal persister cells are a common cause of recurring infections due to Candida albicans a common biofilm infection of implants. [5]
Stenotrophomonas maltophilia is an aerobic, nonfermentative, Gram-negative bacterium.It is an uncommon bacterium and human infection is difficult to treat. [1] Initially classified as Bacterium bookeri, [2] then renamed Pseudomonas maltophilia, S. maltophilia was also grouped in the genus Xanthomonas before eventually becoming the type species of the genus Stenotrophomonas in 1993.
