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.
From Wikipedia, the free encyclopedia. Bacillus cereus is an endemic, soil-dwelling, Gram-positive, rod-shaped, motile, beta hemolytic bacterium. Some strains are harmful to humans and cause foodborne illness, while other strains can be beneficial as probiotics for animals.It is the cause of  fried rice syndrome, as the bacteria are classically contracted from fried rice dishes that have been sitting at room temperature for hours (such as at a buffet).B. cereus bacteria are facultative anaerobes, and like other members of the genus Bacillus, can produce protective endospores.ome strains are harmful to humans and cause foodborne illness, while other strains can be beneficial as probiotics for animals.
