What is fried rice syndrome?
Bacillus cereus is a toxin-producing bacteria that is one of the most common causes of food poisoning, also called “fried rice syndrome.” An estimated 63,000 cases of food poisoning caused by B. cereus occur each year within the U.S., according to a 2019 article published in the journal Frontiers in Microbiology.
What is the treatment for Bacillus?
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.
What does cocci bacteria cause?
The Gram-positive cocci are the leading pathogens of humans. It is estimated that they produce at least a third of all the bacterial infections of humans, including strep throat, pneumonia, otitis media, meningitis, food poisoning, various skin diseases and severe types of septic shock.
Is Bacillus subtilis susceptible to penicillin?
As B. cereus is generally resistant to penicillin, penicillin-sensitive isolates of Bacillus subtilis were also included.
How can bacillus be prevented?
One of the easiest ways to prevent foodborne illness as- sociated with B. cereus is by ensuring that foods are cooked thoroughly and cooled rapidly. One of the leading causes of foodborne infections and intoxications by B. cereus is the improper holding of cooked foods.
