What Is A Pathogen


Pathogens are known to cause infection in the human body. They have the capability of invading a host by way of a break in the protective coating of the cells. These pathogens have the ability to invade almost all types of cells in the body, although it appears to be in the lungs where they most often attack. Some pathogens are natural while others are not. Therefore, humans can be subjected to pathogenic exposure in many different ways.

Pathogens can invade nearly any part of the body. In simple biology, a pathogenic organism in the broadest and most extreme sense, is any microorganism that is able to produce pathogenic effect. However, a microorganism that produces only effect is not a pathogenic organism. A pathogenic microorganism can also be called an infection, or simply a path.

The definition of what is a pathogen can be very complex. There are three basic categories of pathogens: bacterial, viral and fungal. Pathogens can attack both living and dead organic components. A bacterium is a type of pathogen. A virus is not a microorganism but rather an infection. In this sense, viruses are also pathogenic.

Pathogens can cause damage to both the living and dead organic components of their host. They can be classified as primary and secondary pathogens. A primary pathogen is an agent that causes damage to its host without causing any type of secondary infection. A secondary pathogen, on the other hand, is an agent that creates a condition in which the primary pathogen is exposed to a susceptible host and becomes activated and causes damage; however, it does not cause any type of secondary infection.

The first part of what is a pathogen is the physical characteristics that define it. A virus, for instance, has a spherical shape, is extremely fast moving, and has an outer membrane protecting its body. A bacterium has a flat, waxy structure, has two layers of protective membranes, and is very slow moving. All of these physical traits distinguish pathogenic agents from their healthy counterparts.

Pathogens can only infect their intended hosts if they are capable of invading that particular host range. Viruses are not capable of invading their host range, therefore they cannot become pathogenic. Bacteria, on the other hand, are capable of invading and becoming pathogenic if their competent pathogen strains are introduced into their host range. Pathogens that cannot infect their host range cannot become pathogenic even if introduced into their host range.

A second way to differentiate between a pathogen and a bacteria is in the host range. Pathogens can only penetrate their host range, if the host can take them over. If the pathogens are incapable of taking over the host range, they cannot cause disease. Examples of pathogens that cannot infect their host range are bacteria, fungi, protozoa, and viruses.

Lastly, when dealing with what is a pathogen, one must take into account the life cycle of the microbe. Pathogens only become pathogenic when they are able to infect another living cell in their host. In order for a microbe to become pathogenic, it must divide, replicate, and reproduce within its host. A microbe without any of these characteristics is said to be in a non-pathogenic state.

The life cycle of a pathogen also takes into account whether or not there is any level of selective pressure on the pathogen. If there is no selective pressure, the pathogen simply will not go through the process of budding. For instance, if an animal has no natural predators, and it is stuck on its own with nothing to feed on, it will eventually die. In order for this to happen, the animal must undergo a selection process. There has to be a condition that causes the animal to change and become a host. This means that there is a level of selective pressure, which can sometimes lead to the emergence of pathogenic organisms.

Finally, when looking at what is a pathogen, one must take into consideration the effects that the pathogen can have on its host. For instance, if a pathogen were to mutate and create a form of antibiotic resistant tuberculosis, this would have serious consequences for the health of those that would be exposed to the pathogen. Therefore, one needs to take a look at how various forms of infectious diseases can impact on the individuals that are confronted with them. This is particularly important for medical professionals who need to work in settings that are highly infectious, such as clinics, hospitals and other institutions that provide medical treatments to patients that are infected with communicable diseases.

In conclusion, understanding what is a pathogen is important for those that work to stop or reduce the spread of various forms of infectious diseases. In most cases, it is only when you know what an organism is that you can effectively combat it. In addition, once you have determined what an organism is, you need to understand how it can benefit those that become infected. Finally, when looking at what is a pathogen, you need to take a look at the level of selective pressure that is put on the organism. Finally, you need to take a look at the level of genetic variation that is associated with the organism.
