In the correct conditions (with warmth, moisture, nutrients) bacteria can multiply rapidly. The human body can provide these conditions for bacteria to multiply, for example in a cut. Each bacterium splits into two up to every 20 minutes.So, after one hour a single bacterium could have reproduced to give eight bacteria. microorganisms reproduce quickly in the human body.Page: 1  1. 2  2. 3  3.4  4.5  Back.n the correct conditions (with warmth, moisture, nutrients) bacteria can multiply rapidly.

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.
