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.
The disease causing microbes are called pathogens.
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.
Microorganisms or Microbes are referred to as germs.
TB and syphilis are both caused by bacteria.We know that microbes such as harmful bacterium and viruses are responsible for diseases.Tuberculosis is caused by Mycobacterium tuberculosis and syphilis is caused by Treponema pallidium,a spirochaete.The special character about M.tuberculosis is that it is neither gram+ve or gram-ve bacterium,since it does not retain any stain due to a waxy layer with high lipid content.
