What disease is caused by Bacillus megaterium?
megaterium was the culprit of the brain abscess. Importantly, when this bacterium is found in clinical laboratory specimens, it is often reported as “insignificant contaminant”.  However, this case report proves that chronic brain abscesses can be caused by B. megaterium….Table 1.
Are Bacillus bacteria pathogenic?
The majority of Bacillus are non-pathogenic, and many species have been used for biotechnological and industrial applications (Hou et al., 2005; Price et al., 2007). Only a few species of Bacillus are known to cause disease in animals and humans (Spencer, 2003).
Is Bacillus megaterium helpful to humans?
Bacillus megaterium has been an important industrial organism for decades. It produces penicillin amidase used to make synthetic penicillin and several enzymes, like amylases used in the baking industry and glucose dehydrogenase used in glucose blood tests.
Is Bacillus subtilis pathogenic to humans?
B. subtilis is considered a benign organism as it does not possess traits that cause disease. It is not considered pathogenic or toxigenic to humans, animals, or plants. The potential risk associated with the use of this bacterium in fermentation facilities is low.
Is Bacillus harmful to humans?
Some types of Bacillus bacteria are harmful to humans, plants, or other organisms. For example, B. cereus sometimes causes spoilage in canned foods and food poisoning of short duration.
How is Bacillus megaterium treated?
Antibiotics which appear especially useful in the treatment of Bacillus infections are clindamycin and vancomycin, to which the vast majority of strains are susceptible in vitro. Beta-lactam antibiotics, including the new cephalosporins and penicillins, are of little value in this setting.
Is Bacillus megaterium aerobic or anaerobic?
B. megaterium is a Gram-positive, aerobic spore-forming neutralophilic bacterium found in diverse habitats but commonly regarded as a soil bacterium.
What environment is Bacillus megaterium found in?
Bacillus megaterium is a spore-forming bacterium found in soil, seawater, sediments, rice paddies, dried food, honey, and milk (56).
Is Bacillus subtilis an opportunistic pathogen?
Bacillus subtilis are opportunistic, spore forming bacteria, common soil inhabitants. A resistant spore allows bacteria to endure extreme conditions of heat and desiccation in the environments promotes their survival in many instances, even in environments like hospitals.
Does Bacillus cause disease?
Although anthrax remains the best-known Bacillus disease, in recent years other Bacillus species have been increasingly implicated in a wide range of infections including abscesses, bacteremia/septicemia, wound and burn infections, ear infections, endocarditis, meningitis, ophthalmitis, osteomyelitis, peritonitis, and …
What diseases do bacilli cause?
Can you be pathogenic or non pathogenic?
The main difference between pathogenic and nonpathogenic bacteria is that the pathogenic bacteria can cause diseases while the nonpathogenic bacteria are harmless. Moreover, pathogenic bacteria possess several genes that endow the capacity to cause diseases while nonpathogenic bacteria lack such genes.
