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 optimum temperature for goldfish is between 20 Â°C (68 Â°F) and 22 Â°C (72 Â°F). Like all fish, goldfish do not like to be petted. In fact, touching a goldfish can endanger its health, because it can cause the protective slime coat to be damaged or removed, exposing the fishâs skin to infection from bacteria or water-born parasites.
