Infectious diseases are caused by the intrusion of a host organism by foreign organisms, which are generally named microorganisms but are often called microbes. These microbes can also be known as pathogens if they cause an illness. The most common pathogens are bacteria and viruses, although a number of microbes also cause disease. When an organism is linked to an infecting microbe, it is known as the host for that microbe. In the human host, a microorganism causes disease by either disrupting a vital body process or stimulating the immune system to mount a defensive reaction. The goal of a pathogen is to multiply and spread between hosts before being detected by the host’s immune system.
Tetanus is a fatal infectious disease of the nervous system, it is characterized by rigidity and convulsive spasms of the skeletal muscle. The disease is caused by the action of a potent neurotoxin produced during the growth of the bacteria in dead tissues. The pathogen is a bacteria called Clostridium Tetani, which is a motile, anaerobic, spore forming bacteria that can be

Instead tetanus is transmitted by the forming spores of the pathogen Clostridium Tetani which is contaminated through broken skin or underlying tissues. Implicated wounds are often necrotic and most often a result of puncture injury but may include lacerations, splinters, grazes, burns, chronic ulcers and even surgical wounds. Some cases do not recall a wound. Surprisingly, tetanus infection is more likely from a minor wound than a major one, but this is because severe wounds are more likely to be properly treated and cleaned whereas minor wounds are considered too trivial for medical consultation. If the bacteria is successful and they enter the body through a wound, the bacteria can quickly multiply and release a toxin that affects the nerves, causing symptoms such as muscle stiffness and
