What is Bacillus Megatherium?

True to its name, Bacillus megatherium is one of the largest bacteria in existence. It was first discovered in 1884. Up until the 1960s, it was used as the primary model organism among Gram-positive bacteria. More recently, it has become popular in biotechnology, given its recombinant protein production capacity.

This bacteria flourishes when temperatures are between 3-45 Celsius, or 37-113 Fahrenheit, while its optimal conditions are 30 Celsius (86 Fahrenheit). It’s a highly-resistant bacteria, even surviving at temperatures reaching 63 Celsius (145 Fahrenheit) in Antarctica. It’s recognized as a potential agent for the biocontrol of plant diseases, as well as nitrogen-fixing. Synthetic penicillin is produced by sourcing Bacillus megatherium. It is a generally harmless bacteria.

Getting infected with this bacteria is possible due to exposure to water coming from wastewater treatment, cleaning products, drain cleaning products, degreasing products, and bioremediation applications.

Symptoms of Bacillus Megatherium

Scientific literature has not documented any adverse effects on human health as of yet. In fact, this bacteria is considered to be non-pathogenic. Even within individuals suffering from pre-existing health conditions, it is rarely isolated as an opportunistic pathogen. To date, there is only one report of someone getting a skin infection.


Since Bacillus cereus is a bacteria, an infection can be easily treated by using antibiotics. It is very sensitive to antibiotics, unlike many other bacteria. The use of antibiotics should be started as soon as there is a reason to believe you are infected with it.


The best way to prevent infection from Bacillus megatherium is to practice safe eating habits and exercising proper sanitation. Avoid eating foods that have been left out at room temperature for too long. Be very careful regarding what you eat that comes from the water, as well as what comes from the ground. You should always make sure you are eating safely and practicing good hygiene. This will protect you from getting infected with Bacillus megatherium, along with many other bacterial infections.


The cure for Bacillus megatherium is the use of antibiotics. Antibiotics can be used as a cure for this bacterial infection, and there will not be a need to use more than one antibiotic, given the lack of resistance to such treatment.
