Unit 265 Causes And Spread Of Infection

Infection is the process where germs enter a susceptible area in the body, where they multiply, resulting in disease.

Endogenous source of infection are already present inside the body in dominant form. It occurs from the bacteria that are already present inside the body. It only invades or attacks the body tissue if circumstances permit. Like if there is any breach in the body tissues. Many bacterial floras are already present inside the body, like those in the gut flora, the nose and the intestines. These when are in there normal habitat do not cause any infection. But when migrate to other body parts and provided if that is breached, then infection can occur.

Life is full of bacteria that can be beneficial and harmful at the same time. They are the smallest living things that can be found everywhere in the air, soil, water, and even in our body. We actually share our body with many bacteria. Therefore, without the good bacteria we could die because the good bacteria can help digest the food we eat and protects us from bad bacteria that make us sick. On the other hand, living with those organism can be harmful and can cause many diseases. Some of these diseases are produced when bacteria attack the tissues in a plant or animal. Also, it can attack organisms by releasing chemicals. Therefore, they can cause damage to a persons body. These pathogenic organisms are able to reproduce rapidly and split into two identical copies of themselves.

Bacteria can be a scary thing, but some people do not even know what bacteria is but doctors have created antibiotics to destroy it. “Many people are unaware what bacteria are and how antibiotics control them.”(Voss, Bristol) Basically bacteria a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease. Antibiotics are used to destroy bacteria, but if a person is prescribed too many antibiotics they may become immune to antibiotics forever and have to live without a strong immune system. Antibiotics attacks bacteria by preventing it from building a wall to defend itself from the body's immune system. So the body’s immune system can easily kill the bacteria.

Around us, in us, and on us there are organisms that we cannot see; microorganisms. Some of these living beings can be necessary or neutral to our health. However, other microorganisms can cause us infections or diseases, we call them parasites. Each type of parasite targets a specific part of the body. The Hepatitis A virus (HAV) causes specific damage to the liver that can cause the Hepatitis A infection.

It is spread through digesting water or food that has been contaminated with the bacteria

• Food Infection: pathogens grow inside the intestine of a person, eating food contaminated by these pathogens.

Bacteria are single-celled microorganisms. Their cell structure is very unique because they don't have a nucleus, and most bacteria have cell walls similar to plant cells. They come in different shapes including rods, spirals, and spheres. Some bacteria can "swim" around using their tails called flagella. Others just stay still or move with the others. Most bacteria aren't dangerous, but some can make us sick. These bacteria are called pathogens. Pathogens can cause diseases in animals and plants. Some examples of pathogens are food poisoning, pneumonia, and tetanus. This online

Bacteria are single celled. They consist of enzymes, DNA, cell membrane, and a cell wall. The cell wall of bacteria is flexible and made of peptidoglycan. Bacteria can be good or bad. The cell wall can attract other bacteria or protect against pathogenic bacteria. Most bacteria is beneficial and does not cause disease. When pathogenic bacteria get into the body, it reproduces and crowds out the good bacteria. Some common diseases caused by bacteria are E. coli, salmonella, h. pylori, gonorrhea, meningitis, staph infection, pneumonia, ear infection, and strep throat. Bacterial diseases are contagious and can cause toxic shock syndrome, blood poisoning, or kidney failure.

A bacteria is a living cell organism that can survive inside our body and other non living objects as well. There are both good and bad bacterias and the good bacteria is known to helps fight against the bad bacteria that makes it's way into our bodies. According to a www.righthealth.com, less then 1% of bacteria is actually harmful to us. In fact, we couldn't survive without bacteria in our body. A bacteria infection is described as an imbalance of bacteria that can cause harm to our bodies. It occurs when the harmful bacteria enter our body through contaminated, non pasteurized or expired foods; cuts or

Bacteria are tiny single-cell microorganisms that thrive in diverse environments, They live within the soil, the ocean and in the human gut, Bacteria are prokaryotes. Bacteria is an issue because it causes salmonella, gonorrhoea and many other diseases that are deadly and kill people. Each year in the united states, at least 2 million people die of bacterial diseases (Dr.Frieden,2013), bacteria is an issue because it kills so many people around the world, most times bacterial infections can be prevented by good hygiene. An infection is made up of bacteria, a human with an infection has another organism inside their body which gets their sustenance from that person (Nordqvist, 2014). Why infection important

To begin, viruses require a host to survive and replicate and transfer from on organism to another. For example, the HIV virus can be transmitted by bodily fluids infected with the virus such as blood, sperm, seminal fluid, and breast milk. All in which contain some form of cells for the virus to replicate itself in order to survive. If the host body were to die, all of the cells would eventually die as well, causing the virus to lie dormant.

Bacteria are the smallest microorganisms being known by their astonishing dividing capacity. They divide by binary fussion meaning that one cell grows and splits into two cells. The process is exponential and provides rapidly increasing populations. Bacteria, as well as fungi and viruses all form a big category, spread infinitely , known under the name germs and are the microorganisms

Many of the people think that bacteria and viruses are the same thing, in reality they have some differences. In one hand the bacteria is a single-celled microorganisms that are in many different types of the environment. The cool part of bacteria is that they can live in both of the surface, hot and cold surface. Many of the bacterial that are produced are not dangerous for the human body some of the just make the person sick, for example, strep throat, tuberculosis, and the urinary tract infections. Also, another of the difference between this two are that antibiotics drugs can usually kill the bacteria that is in the human body, but this are not effective against the viruses. So the bacterias can be control or be deleted from the human's

Viruses do not have the chemical machinery needed to survive on their own. They, thus seek out host cells in which they can multiply. These viruses enter the body from the environment or other individuals from soil to water to air via nose, mouth, or any breaks in the skin and seek a cell to infect.
