Is Bacillus megaterium harmful to humans?
In the case of Bacillus megaterium strain ATCC 14581, the organism is not hazardous to human health or the environment; and exposure to the environment and Canadians is medium. Therefore, it is concluded that Bacillus megaterium strain ATCC 14581 is not harmful to human health or to the environment.
What diseases are caused by Bacillus?
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 …
How do you get Bacillus megaterium?
B. megaterium grows at temperatures from 3 °C to 45 °C, with the optimum around 30 °C. Some isolates from an Antarctic geothermal lake were found to grow at temperatures up to 63 °C. It has been recognized as an endophyte and is a potential agent for the biocontrol of plant diseases.
What diseases are caused by Bacillus subtilis?
Infections attributed to B. subtilis include bacteremia, endocarditis, pneumonia, and septicemia. However, these infections were found in patients in compromised immune states.
How can you tell the difference between Bacillus species?
Bacillus anthracis and Bacillus cereus can usually be distinguished by standard microbiological methods (e.g., motility, hemolysis, penicillin susceptibility and susceptibility to gamma phage) and PCR.
Is Bacillus megaterium helpful to humans?
megaterium has often been used in the laboratory, and is used as an industrial organism that is able to produce a variety of proteins and sources of bioremediation. Bacillus megaterium is a good source of industrial proteins because it is both a desirable cloning host and produces a large variation of enzymes.
What does Bacillus subtilis do to the human body?
Beneficial Impacts of Bacillus subtilis on Gut Health. Research conducted on B. subtilis as a probiotic shows that it is likely effective in boosting immune activity, protecting the body from pathogens, and improving gut health. The bottom line: as spore-forming bacteria, B.
Where is Bacillus subtilis found in the body?
subtilis) is a Gram-positive, aerobic bacterium. It is rod-shaped and catalase-positive. B. subtilis is found in soil and the gastrointestinal tract of ruminants and humans.
What foods contain Bacillus?
The consumption of vegetative cells and spores of Bacillus spp. by human beings is frequent through fermented foods and raw vegetables. A diverse range of Bacillus species are found to be associated to the natural fermentation of soy, locust been, maize, rice and many more substrates.
Can a human be infected with Bacillus megaterium?
In humans, Bacillus megaterium is generally considered to be non-pathogenic, and is rarely isolated as an opportunistic pathogen in individuals with pre-existing health conditions. A single report of a skin infection in a healthy individiual has been reported.
What are the effects of Bacillus megaterium 14581?
In the unlikely event of infection, Bacillus megaterium strain ATCC 14581 is sensitive a variety of antibiotics. There is no conclusive evidence in the scientific literature to suggest that Bacillus megaterium strain ATCC 14581 is likely to have adverse effects on the environment.
How are the cells of Bacillus megaterium joined together?
The cells often occur in pairs and chains, where the cells are joined together by polysaccharides on the cell walls . In the 1960s, prior to the development of Bacillus subtilis, B. megaterium was the main model organism among Gram-positive bacteria for intensive studies on biochemistry, sporulation and bacteriophages.
What kind of complications can be caused by Bacillus?
When these bacteria cause localized infection such as pneumonia, pan-ophthalmitis, visceral abscess, or musculoskeletal infections, tissue necrosis and profound morbidity are the rule. The frequency of these complications following bacteremia appears to be low but cannot be estimated from our experience or that reported in the literature reviewed.

What did the Canadian government do about Bacillus megaterium?
The Government of Canada conducted a science-based evaluation of Bacillus megaterium strain ATCC 14581, called a screening assessment, to address the potential for harm to Canadians and the environment.
Why was B.megaterium classified as a dry cough?
Based on its characteristics, it was classified as B. megaterium. The information was disclosed to the patient, and the intravenous antibiotic therapy was discontinued. The patient’s initial dry cough had resolved, and she had no evidence of any cutaneous, respiratory, or neurologic sign of disease.
