Around the 19th century
Robert Koch, in 1877, discovered that anthrax microbes caused anthrax. He further isolated tuberculosis in 1882. This followed Louis Pasteur's discoveries in 1862 of pasteurization as a way to prevent spoilage of various beverages. Along with Koch and Pasteur, Ferdinand Cohn, are considered the three fathers of modern bacteriology.
It uses microbes to cause disease and ultimately kill people
Microbial disease.
Majority of the microbes do not cause the disease. The disease causing microbes also, probably, keeps your species healthy and your immune system tuned.
Yes, people do have microbes living in their mouths (particularly those which cause tooth decay) and those can cause a disease if they get into the blood by way of a bite.
Disease-causing microbes are called pathogens. These include bacteria, viruses, fungi, parasites, and prions that can cause infections and illnesses in humans, animals, and plants.
Compare the original microbes with the microbes in the new culture.
The are hundreds if not more microbes that can cause disease. You need to narrow down this question more.
There are thousands of different types of microbes. They are all microscopic but at the same time they are very much different from each other. So each can cause individual or no disease. In fact very few of them cause diseases.
False - "microbe" can be any microorganism, not just those that cause disease.
Microbes might be either useful or harmful. Those that cause disease are of course, harmful, but there are millions of microbes in your body that aid in functions such as digestion. There are also microbes that occur in food products. Yeast is a good example. Also yogurt contains microbes as part of the product.
Germs are also known as microorganisms or microbes. This includes bacteria, viruses, fungi, and protozoa that can cause disease or infection in humans.
Some common microbes that cause disease in humans include bacteria (such as Escherichia coli or Staphylococcus aureus) and viruses (such as Influenza virus or Human Immunodeficiency Virus). These microbes can lead to a wide range of illnesses and infections depending on the specific type and strain.
