Where do most pathogens live?
They inhabit virtually every environment on the planet and the bacteria carried by an average human, mostly in their gut, outnumber human cells. The vast majority of microbes are harmless to us, and many play essential roles in plant, animal and human health.
Where are the pathogens found?
All viruses are obligate pathogens as they are dependent on the cellular machinery of their host for their reproduction. Obligate pathogens are found among bacteria, including the agents of tuberculosis and syphilis, as well as protozoans (such as those causing malaria) and macroparasites.
Why do pathogens live in the human body?
A pathogen is an organism that causes disease. Your body is naturally full of microbes. However, these microbes only cause a problem if your immune system is weakened or if they manage to enter a normally sterile part of your body. Pathogens are different and can cause disease upon entering the body.
Where do pathogens live and multiply?
A reservoir is the principal habitat in which a pathogen lives, flourishes and is able to multiply. Common reservoirs for infectious agents include humans, animals or insects and the environment.
Where do microbes live on or within the skin?
Microorganisms (viruses, bacteria and fungi) and mites cover the surface of the skin and reside deep in the hair and glands.
Where is the reservoir of the microorganism?
The reservoir is the place where microorganisms live, such as in humans and animals, in soils, food, plants, air or water. The reservoir must meet the needs of the pathogen in order for the pathogen to survive and multiply.
Where do resident microorganisms live?
The resident flora (resident microbiota) consists of microorganisms residing under the superficial cells of the stratum corneum and can also be found on the surface of the skin. Staphylococcus epidermidis is the dominant species,66 and oxacillin resistance is extraordinarily high, particularly among HCWs.
Where did the microorganism Enter John’s body?
Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.
