What are bacterial pathogens?

pathogen comes from two Greek words: pathos means "disease" and genain , which means "produce". It refers to an agent or microorganism capable of producing the disease. Prions are an example of a pathogenic agent. When it comes to the spread of microorganism, it can be a cushion, protozoan or bacterial pathogen. Viruses can be included as microorganisms, but because there is a discussion of whether they live, they can also be put into the category of substances. Examples of bacterial pathogens include mycobacterium tuberculosis, Streptococcus, Bacillus Anthracis, Rickettsia, Listeria and Salmonella . The pathogenic of bacteria is a measure of its ability or probability to cause disease, measured quantitatively as its virulence. Specific factors that correspond to virulence of bacterial pathogenory to as virulence factors

virulence factors include a number of properties that contribute to its success in the stage of its hostor on his host and causing the disease. Bacterial pathogens can have relatively few or many virulent factors. The factors that bacterial pathogens may have includes the production of toxins, proteins that help to connect to the host and the ability to protect their own surface.

Another way to look at the efficiency of bacterial pathogens is to consider them in terms of invasiveness and toxigenesis. In this case, the ability to produce toxins that affect tissue close even far from the point of growth or invasion, separated from all factors that allow bacteria to successfully attack another organism.

Bacterial pathogens begin their attacks on hosts through colonization and settled in the host tissues, usually a point that maintains contact with the external environment. For the human host, this would include a conjunctival, digestive tract, respiratory tract and urogenital tract. Bacterial pathogENY use adhesions to interact with receptors on host cells.

Another phase of infection with bacterial pathogens is called invasion. Factors that can help invasive bacteria include substances called invasions that have two purposes: damaging host cells and allowing the spread of bacterial pathogen.

Infectious diseases caused by bacterial pathogens can be treated with one of three different groups of antimicrobial substances. A group of naturally occurring antimicrobial substances is called antibiotics; A group of chemically synthesized antimicrobial substances is called chemotherapeutic agents; And hybrids begin with a naturally occurring substance that is modified. Some members of the first group can now be synthesized.
