Anthrax may affect the skin, the lungs, or, rarely, the digestive. These bacteria include those that cause anthrax Anthrax Anthrax is a potentially fatal infection with Bacillus anthracis, a gram-positive, rod-shaped bacteria (see figure ). Such use is contrary to international law and has rarely taken place during formal warfare in modern history, despite the. Many resident flora are actually helpful to people-for example, by helping them digest food or by preventing the growth of other, more dangerous bacteria.Ĭertain bacteria have the potential to be used as biological weapons Biological Weapons Biological warfare is the use of microbiological agents as weapons. There are at least as many bacteria in our resident flora as there are cells in the body. Such bacteria are called resident flora Resident Flora Healthy people live in harmony with most of the microorganisms that establish themselves on or in (colonize) nonsterile parts of the body, such as the skin, nose, mouth, throat, large intestine.

Two types of bacteria shapes skin#

Many bacteria live on and in the bodies of people and animals-on the skin and in the airways, mouth, and digestive, reproductive, and urinary tracts-without causing any harm. Some bacteria have been reported even to live in radioactive waste. They live in soil, seawater, and deep within the earth’s crust. The 3 most common shapes are coccus (spherical), bacillus (rod-shaped), and spiral. The first step is to observe the shape(s) of the bacteria on the slide. There are thousands of different kinds of bacteria, and they live in every conceivable environment all over the world. Once you have used staining to determine whether your bacteria are Gram positive, Gram negative, or acid-fast, it's time to narrow down the type of bacteria. They are among the earliest known life forms on earth. If left untreated, it can affect your heart and nervous system and cause arthritis.Bacteria are microscopic, single-celled organisms.

Infection with Borrelia burgdorferi may, but does not always, result in a typical 'bull's-eye' rash. Borrelia burgdorferi is transmitted through the bite of an infected deer tick and causes Lyme disease 3. Additional lesions or rashes can develop elsewhere on the body if left untreated. Infection typically begins as a single sore at the site of infection. Treponema pallidum causes the sexually transmitted disease syphilis. Two well-known spirochetes that cause disease in humans are Treponema pallidum and Borrelia burgdorferi.

They typically move in a distinctive rotating manner that allows them to be mobile in mucus-lined tissue or viscous environments.

Spirochetes are long, thin and flexible corkscrew-shaped bacteria.

Helicobacter pylori may be living in a person’s stomach without causing symptoms, but this organism is also associated with stomach inflammation and ulcers in many people.

Spirilla are another subgroup of bacteria with a more rigid, corkscrew-like spiral shape.
