- Infectious diseases are the invasion of a host organism by a foreign replicator, generally microorganisms, often called microbes, that are invisible to the naked eye. Microbes that cause illness are also known as pathogens.The most common pathogens are various bacteria and viruses, though a number of other microorganisms, including some kinds of fungi and protozoa, also cause disease. An infectious disease is termed contagious if it is easily transmitted from one person to another.he most common pathogens are various bacteria and viruses, though a number of other microorganisms, including some kinds of fungi and protozoa, also cause disease.

Pathogen Although the vast majority of bacteria are harmless or beneficial, a few pathogenic bacteria can cause infectious diseases.here are several substrates including pathways where the pathogens can invade a host. The principal pathways have different episodic time frames, but soil contamination has the longest or most persistent potential for harboring a pathogen. Diseases caused by organisms in humans are known as pathogenic diseases.

- 1. Bacteria: are microorganisms with a size of up to 5 µm and represent the most important group of pathogens when discussing microbiological contamination.According to the constitution of their cell wall, bacteria can.. Viruses: subcellular biological objects with a size of 20-200 nm. They exist with and without envelopes (shells mostly derived from host membranes covering the virus) and can cause serious infections (see Figure 2, HI-Virus).

- An organism that a microbe infects is known as the host for that microbe. In the human host, a microorganism causes disease by either disrupting a vital body process or stimulating the immune system to mount a defensive reaction.he most common pathogens are various bacteria and viruses, though a number of other microorganisms, including some kinds of fungi and protozoa, also cause disease. An infectious disease is termed contagious if it is easily transmitted from one person to another.

- Pathogens are microorganisms-such as bacteria and viruses-that cause disease. Bacteria release toxins, and viruses damage our cells. White blood cells can ingest and destroy pathogens by producing antibodies that destroy the infectious microorganisms, and antitoxins to neutralise toxins created as a by-product.

Difference Between Antigen and Pathogen Pathogens are any foreign organisms that cause diseases in host plants and animals; e.g. virus and bacteria. Antigen is a molecule located in the cell wall of bacteria or the coating of organisms.Antigen causes our immune system to produce the antibody against it and protect our body from harmful foreign organisms.t causes our immune system to produce the antibody against it. Antibody is used by the immune system to identify and neutralize the foreign particles like bacteria and viruses. Basically, antigens are categorized as self-antigen and non-self-antigen.

Bacteria: More Than Pathogens A bacterium differs from a virus in its structure and in the way it inhabits a host. Whereas most bacteria live as independent cells with a membrane to separate them from the outside world, viruses can only multiply inside, and to the detriment of, the cells they infect.

What is the difference between microbes and pathogens? Best Answer: A microbe is any small organism like a protist, bacterium, alga or fungi. If you wanna be really broad with the term, you could include viruses, too. Not all microbes cause diseases. To put it broadly, a pathogen is anything that causes disease. Pathos is the root meaning sickness or feeling, whereas gen is the root meaning to start or give rise.. So pathogen is something that starts up sickeness. Not all pathogens are microbes.

Difference Between Antigen and Pathogen Pathogens are easily called as infectious agents. We contact pathogens in our daily life. These are microorganisms that cause diseases in host plants and animals; e.g. virus, bacteria, and fungi. Not all microbes are harmful; pathogens refer specifically to the ones that can cause disease in the host.t causes our immune system to produce the antibody against it. Antibody is used by the immune system to identify and neutralize the foreign particles like bacteria and viruses. Basically, antigens are categorized as self-antigen and non-self-antigen.
