Robert Koch (1843-1910) was a German physician and microbiologist who showed that "the key to the identification of bacterial pathogens was the isolation of pure cultures."
What are Koch's postulates?
In the course of his studies of anthrax and tuberculosis, Robert Koch formulated rules of procedure for proving that a certain microorganism is the cause of a particular disease. These rules, known as Koch's postulates, are still used today:
1. It must be shown that the microorganism in question is always present in diseased hosts.
2. The microorganism must be isolated from the diseased host and grown in pure culture (i.e., in a culture containing only that one species of microorganism).
3. Microorganisms obtained from the pure culture, when injected into a healthy, susceptible host, must produce the disease in that host.
4. Microorganisms must be isolated from the experimentally infected host, grown in pure culture, and compared with the microorganisms from the original culture.
In 1880, a German doctor named Robert koch developed a rule that is still in use today
Koch's rules formed the basis for methods of control. He had become influenced by working with cholera to conserve water supplies.
The mutation rule states that the state of mutations are in a mutated state when compared to a normal state. This is a slight mutation from the original stated rule.
H2S does follow the octet rule. When you draw the Lewis Structure for H2S, it looks like this: If you count up the lone pairs and sigma bonds (each worth 2), there are 8, thus, H2S follows the octet rule.

Primary Koch infection is another name for Tuberculosis. This disease is an illness that attacks the lungs and it can be fatal to humans.
Koch's infection means infection by tuberculosis causing bacteria. Upper lobe is usually involved. Exact reason for this is not known. Probably the upper lobe is poorly ventilated.
Koch's disease is another word for Tuberculosis and there is not a cure for it. There are treatments and vaccines that can be done to prevent someone from getting it though.
L'Hôpital's Rule or L'Hôspital's Rule
Aristotle came up with the rule by few, rule by one, and the rule by many.
