The germ theory of disease is the currently accepted scientific theory of disease it states that many diseases are caused by microorganisms these small organisms, too small to see without magnification, invade humans, animals, and other living hosts. For instance, the theory of biogenesis was first introduced by a man named rudolph virchow, who eagerly challenged the current theory of spontaneous generation at the time spontaneous generation theory was the thought that some forms of life could actually be spontaneously created out of thin air.
The theory of biogenesis led the way for the germ theory of disease by providing evidence that living cells need other living cells to develop louis pastuer proved this concept with a series of experiments in which he proved that microorganisms are present in the air.
3) the germ theory of disease and scientific studies show that the most important means of avoiding infectious disease is simply washing one's hands (especially after using the bathroom, and before touching food. The germ theory of disease is the currently accepted scientific theory of disease it states that many diseases are caused by microorganisms these small organisms, too small to see without magnification, invade humans, animals, and other living hosts their growth and reproduction within their hosts can cause a disease.
Biogenesis is important for the germ theory of disease, and the two are dependent on one another microorganisms, which are microscopic living cells that are bacteria, archaea, fungi, protozoa, microscopic algae, or viruses, can reproduce, and are the cause of disease.
The antecedents to the germ theory were as follows: disproving the “evolutionary” idea of spontaneous generation of microbes perfecting the microscope the observation and proving of biogenesis the discovery of fermentation or spoilage of foods (milk, wine, beets) caused by microbes the demonstration of protozoan parasites as the cause of pebrine (silkworm disease) and showing that bacteria caused animal diseases like chicken cholera, anthrax, and rabies.
