The germ theory of disease is the theory that microorganisms are the cause of specific diseases, and the theory of biogenesis claims that living cells must come from other living cells. 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. These living microorganisms will invade anything that they can live on, (such as food, animals, plants). With this being said, these microorganisms are invading live cells, and reproducing, which can then cause disease.
Who first suggested that the use of aseptic techniques would have a profound effect on the contraction of human diseases? In your answer, be sure to describe this effect. Aseptic technique, which is still used today, is a procedure that is preformed under sterile conditions to prevent any contamination from microorganisms. Joseph Lister, an English surgeon, first applied this technique and encouraged this in surgery, and for medical procedures to keep from transmitting infection to patients. Lister applied the germ theory to medical procedures, as he was aware that physicians were not properly disinfecting their hands, and were transmitting infections from one patient to another, (Tortora, Funke & Case ). Aseptic technique is practiced today in the medical field to keep patients from infection. By using sterile equipment and applying this technique, we are protecting patients from microbial contamination that could potentially harm them.
