UNVERIFIED_ORG: Bacillus cereus strain 121B

Bacillus cereus strain 121B is a Gram-positive, rod-shaped bacterium that exhibits a chains cell arrangement and is classified as an aerobe, requiring oxygen for growth. This strain is motile, possessing flagella that facilitate movement. It thrives optimally at a temperature of 25°C and is considered mesophilic, indicating it can grow within a moderate temperature range. The strain is free-living and has a diverse habitat, being associated with a wide array of hosts including Homo sapiens, Gallus gallus (chickens), various Metazoa, Insecta, Oryctolagus cuniculus (rabbits), Galleria mellonella (wax moths), Mammalia, Nematoda, and even deep-sea organisms like Alvinocaris longirostris. This broad host range signifies its ecological versatility and potential impact across different biological systems. Bacillus cereus strain 121B is known for its pathogenicity in humans, leading to a variety of health issues. These include severe conditions such as bacteremia, pneumonia, meningitis, and foodborne illnesses characterized by symptoms like diarrhea and vomiting. The strain can also cause systemic infections such as sepsis and neonatal meningitis, as well as non-gastrointestinal infections and infections in immunocompromised individuals. The extensive list of health effects associated with this strain underscores its significance in food safety and public health. Its ability to cause both gastrointestinal and systemic diseases highlights the importance of monitoring and controlling Bacillus cereus in food products to prevent foodborne illnesses and safeguard human health.
