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.
Bacillus cereus. This type of bacterium is responsible for food poisoning although it has a positive effect in the form of a probiotic food additive for animals. Bacillus cereus or B. cereus for short causes food poisoning as a result of improperly prepared and stored food.This allows these bacteria to multiply and produce âenterotoxinsâ which are the direct cause of this illness.hey are found along with the. and. bacteria and can often dominate these two strains of bacteria. There are several strains of the bacillus cereus bacteria, some of which are beneficial to animals but others are harmful to humans.
