It’s difficult for us to fully comprehend the significant medical revolution known as “germ theory” and how animal research played a role in its development today.
It appears hard to imagine that people once thought that malodors might cause disease or that “bad spirits” might make someone sick.
However, these ideas were prevalent before the mid-19th century when germ theory began to take hold.
What is germ theory?
Germ theory is a medical theory that posits that certain diseases are caused by the presence of pathogens in the body. These pathogens can be bacteria, viruses, or other microorganisms.
The theory arose in the 19th century when doctors began to notice that certain diseases seemed to be contagious.
They also began to notice that hygiene played a role in disease transmission. By sterilizing instruments and washing their hands, doctors could significantly reduce the spread of infection.

Who discovered germ theory?
The discovery of germ theory is typically credited to French chemist and microbiologist Louis Pasteur.
In the 1860s, Pasteur conducted a series of experiments that showed that microorganisms were responsible for the spoiling of food and the fermentation of wine.
He also demonstrated that these microorganisms could cause disease. These findings were a major breakthrough in our understanding of human health and disease.
While Pasteur is rightfully seen as the father of germ theory, it is important to note that he was not the first scientist to propose this idea.
In the early 1800s, Italian physician Agostino Bassi observed that a microscopic fungus was responsible for a devastating silkworm disease.
However, it was Pasteur’s work that really brought germ theory into the mainstream and laid the foundation for modern medicine.

How did germ theory develop?
After centuries of speculation about the cause of disease, the development of germ theory finally provided a scientific explanation for the spread of infection.
The theory began to take shape in the early 1800s, when scientists started to notice that certain microscopic organisms were present in diseased tissue.
However, it was not until the work of Louis Pasteur that germ theory began to gain widespread acceptance.
Pasteur’s experiments convincingly showed that specific microbes could cause specific diseases, and his findings helped to launch a new era of medical research.
Over the past century, continued advances in microbiology have led to a better understanding of how germs cause disease and how best to prevent and treat infections.
Today, germ theory is taken for granted, but it remains one of the most important discoveries in the history of medicine.

How did germ theory affect the medical views?
In the 1800s, the medical community began to develop a greater understanding of the role of germs in disease. Previously, most doctors believed that diseases were caused by an imbalance of the body’s four touches of humor:
- Blood
- Phlegm
- Yellow bile, and
- Black bile.
However, as doctors began conducting more detailed autopsies and observing patients more closely, they began to suspect that germs might play a role in illness.
In 1854, Dr. John Snow published a report linking cholera to contaminated water, and his work helped to strengthen the case for germ theory.
By the end of the century, most doctors had adopted germ theory as their primary explanation for disease. This shift in thinking had a profound impact on medical care.
Doctors began using sterilization techniques to prevent infection, and they developed vaccines to protect against illnesses such as polio and smallpox.
As a result of these advances, medicine became much more effective at preventing and treating illness.

Is germ theory true?
The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms, known as pathogens, are responsible for causing diseases.
These pathogens can be bacteria, viruses, fungi, or protozoa.
They invade the body and multiply, resulting in disease. The germ theory has been extensively tested and supported by evidence. Many diseases that were once a mystery can now be explained by this theory.
For example, the discovery of bacteria in the 1700s helped to explain how cholera is spread.
The germ theory has also led to important advances in medicine, such as the development of vaccines and antibiotics.
While there is still much to learn about the role of germs in disease, the germ theory is an important tool for understanding how diseases develop and how they can be prevented.
