PRESENTATION OUTLINE
Bacterial growth is the asexual reproduction, or cell division, of a bacterium into two daughter cells, in a process called binary fission.

Bacteria is very diverse. They are categorized in many categories, including whether they need air, where they dwell, their cell structure, shape, and diseases they cause.

The microbial growth involves four phases
1.lag phase- that is when the microbe first adjust itself to the surrounding environment and stabilizes itself to the conditions near it.
2.log phase-the microbes, after having good food from the environment will be ready to multiply so it will increase in number.
3.stationary phase-the multiplication of microbes reach a saturation point where they compete for space to live and there wont be further multiplication.
4.decline phase-where the death of the organism occur because there is not enough nutrients or space for them to live. It may die even when the neighboring microbe produce toxins against it.

HOW WOULD YOU STERILIZE A MATTRESS USED BY A PATIENT WITH BUBONIC PLAGUE?
I would use a hepa vacuum, ultraviolet germicidal radiation and light enzyme mostly to kill remaining colonies.

How would you sterilize Intravenous glucose-saline solutions?
I would put it in the autoclave.

How would you sterilize used disposable syringes?
I would dispose of them in a special bin for bio waste since they are a one time use, but if not than ethylene oxide.

How would you sterilize tissue taken from patients ?
I would use Gamma irradiation and gas sterilization with ethylene oxide. The gas penetrates the tissue.
Bacteria commonly found in hospitals .
Hospitals have become particularly notorious for spreading lethal infections. According to the most recent report by the US Centers for Disease Control and Prevention, hospital acquired infections now affect one in 25 patients.
