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.
In addition, Bacillus cereus is an opportunistic human pathogen and is occasionally associated with infections, causing periodontal diseases and other more serious infections [5]. Immunocompromised patients are susceptible to bacteremia, endocarditis, meningitis, pneumonia, and endophthalmitis [6].. cereus has a circular chromosome measuring 5,411,809 nt in length and was completely sequenced using the shotgun sequencing method [7]. The genome structure of B. cereus consists of 5481 genes, 5234 protein coding, 147 structural RNAs, and 5, 366 RNA operons [1].
