Detailed explanation-1: -Why it matters: Bacteria are among the fastest reproducing organisms in the world, doubling every 4 to 20 minutes.
Detailed explanation-2: -So, 1 bacterium can multiply to 2 in 20 minutes, 4 in 40 minutes, and so on.
Detailed explanation-3: -When conditions are favourable such as the right temperature and nutrients are available, some bacteria like Escherichia coli can divide every 20 minutes. This means that in just seven hours one bacterium can generate 2, 097, 152 bacteria.
Detailed explanation-4: -Generation time is the time it takes for a population of bacteria to double in number. For many common bacteria, the generation time is quite short, 20-60 minutes under optimum conditions. For most common pathogens in the body, the generation time is probably closer to 5-10 hours.
