Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual. Asexual reproduction involves only one parent and the offspring is genetically similar to the parent. Sexual reproduction involves two parents and the offspring has a fusion of the characteristics of both the parents.
Most bacteria, including Salmonella and E.coli, reproduce by binary fission. During this type of asexual reproduction, the single DNA molecule replicates and both copies attach to the cell membrane. The cell membrane begins to grow between the two DNA molecules. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward. A cell wall then forms between the two DNA molecules dividing the original cell into two identical daughter cells.
