Bacteria usually reproduce asexually. In case of sexual reproduction, certain plasmids genetic material can be passed between bacteria. On the other hand, viruses mainly carry information-for example, DNA or RNA, packaged in a protein and/or membranous coat.Viruses harness the host cell's machinery to reproduce.acteria usually reproduce asexually.

The vegetative form of B. cereus grows in a range of 10 to 50Â°C, with a temperature optimum between 30 and 40Â°C. However, the individual cold-tolerating strains can also multiply at temperatures of 4 to 6Â°C; in these cases the generation times are, however, considerably longer.
The best way to avoid food poisoning from Bacillus cereus and other â often nastier â bacteria is to always cook and store food safely. 1  Keep hot food hot (above 60Â°C) and cold food cold (below 5Â°C). Throw away any cooked and/or perishable food that is left out of refrigeration for more than four hours.
