Another example is Bacillus cereus, which can be found in contaminated rice even after it is cooked.
For example, Clostridium botulinum is a common concern in canned food, so foods are canned using high pressure and high heat to kill spores. Since these pathogens can form spores, they are commonly not inactivated with usual food treatment methods. These include Clostridium botulinum (the cause of botulism, which can lead to paralysis and death) and Bacillus cereus (a common cause of diarrheal and emetic food poisoning). Each ring represents a protective layer, and the squiggle in the center is the protected package of DNA.Ĭlostridium and Bacillus are two spore-forming genera 1, which also contain several foodborne pathogens that can cause foodborne illness in humans. Spore-forming bacteria are very similar! The spore in the coloring page below is represented by the thick, frilly oval with rings inside of it. In the spring, when more food is available, they wake up and continue life as usual. Think of this like bears hibernating for the winter due to decreased food sources. When in unfavorable environments, spores are not active.
#SPORE FORMING BACTERIA CODE#
Each spore is composed of multiple layers of protective coats and a core containing the code for life (DNA in this case) and cellular machinery that bacteria need to grow and eventually divide into new cells.
