Bacterial diseases: Introduction
Bacterial diseases include any type of illness or disease caused by bacteria, a type of microbe. Microbes are tiny organisms that cannot be seen without a microscope and include viruses, fungi, and some parasites as well as bacteria. The vast majority of bacteria do not cause disease, and many bacteria are actually helpful and even necessary to good health. Millions of bacteria normally live on the skin and in the intestines and can also be found on the genitalia. Bacterial diseases result when the harmful bacteria get into an area of the body that is normally sterile, such as the bladder, or when they crowd out the helpful bacteria in places such as the intestines.
Harmful bacteria are called pathogenic

Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb or diseased as a result of secondary infections; these occur as a result of the body's defenses being compromised by the primary disease.Secondary infections, in turn, can result in tissue loss causing fingers and toes to become shortened and deformed, as cartilage is absorbed into the body.

Primary Cause of Leprosy
The primary cause of Leprosy is the result: * of transmission from another person under rare circumstances, such as immunocompromised people or during surgery with contaminated surgical tools, or according to "rare circumstances" as noted from reputable sources.
Mycobacterium leprae
Mycobacterium leprae and Mycobacterium lepromatosis are the causative agents of leprosy. M. lepromatosis is a relatively newly identified mycobacterium isolated from a fatal case of diffuse lepromatous leprosy in 2008.[2][3]
An intracellular, acid-fast bacterium, M. leprae is aerobic and rod-shaped, and is surrounded by the waxy cell membrane coating characteristic of Mycobacterium species.[35]
Due to extensive loss of genes necessary for independent growth, M. leprae and M. lepromatosis are obligate pathogens, andunculturable in the laboratory, a factor that leads to
