A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
Common names include ragwort, common ragwort, [4] stinking willie, [5] tansy ragwort, benweed, St. James-wort, stinking nanny/ninny/willy, staggerwort, dog standard, cankerwort, stammerwort. In the western United States it is generally known as tansy ragwort , or tansy , though its resemblance to the true tansy is superficial.
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Norovirus is primarily spread through contact with contaminated surfaces or direct contact with someone who has the virus. It can also be spread through food, particularly raw or undercooked ...
use of a warm air hand dryer spread micro-organisms up to 0.25 metres from the dryer; paper towels showed no significant spread of micro-organisms. In 2005, in a study conducted by TÜV Produkt und Umwelt, different hand drying methods were evaluated. [12] The following changes in the bacterial count after drying the hands were observed:
The human virome is the total collection of viruses in and on the human body. [1] [2] [3] Viruses in the human body may infect both human cells and other microbes such as bacteria (as with bacteriophages). [4] Some viruses cause disease, while others may be asymptomatic.
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Phages can be bioengineered to target multidrug-resistant bacterial infections, and their use involves the added benefit of preventing the elimination of beneficial bacteria in the human body. [31] Phages destroy bacterial cell walls and membrane through the use of lytic proteins which kill bacteria by making many holes from the inside out. [ 272 ]
