Bacillus cereus strain FM1

Bacillus cereus strain FM1 is a Gram-positive, rod-shaped bacterium that forms chains and is classified as an aerobe. This strain is known to possess mobility due to the presence of flagella and thrives optimally at a temperature of 25°C, falling within the mesophilic temperature range. The bacterium has a single replicon and a single membrane, indicating a relatively simple genetic and structural organization. B. cereus strain FM1 exhibits a free-living biotic relationship and can inhabit multiple environments. It has a wide host range, affecting various species including Homo sapiens (humans), Gallus gallus (chickens), Metazoa, Insecta, Oryctolagus cuniculus (rabbits), Galleria mellonella (wax moth larvae), Mammalia, Nematoda, Alvinocaris longirostris (a type of shrimp), Oscheius (a genus of nematodes), and Chelidonium majus (a flowering plant). The strain is associated with numerous health effects, particularly in humans, where it can lead to serious conditions such as bacteremia, pneumonia, meningitis, and multiple forms of sepsis. Additionally, it is implicated in foodborne illnesses, including food poisoning and severe gastrointestinal infections. The pathogenicity of B. cereus strain FM1 highlights its role in both food safety incidents and infectious diseases across various animal and human hosts. Understanding the ecological and biological implications of B. cereus strain FM1 is crucial, especially in the context of food safety and public health, given its capacity to cause severe illnesses in diverse organisms, including humans and insects.
