What are disease producing bacteria called?
What are disease producing bacteria called?
Microorganisms that cause disease are collectively called pathogens. Pathogens cause disease either by disrupting the bodies normal processes and/or stimulating the immune system to produce a defensive response, resulting in high fever, inflammation? and other symptoms.
What does infectious disease cover?

What is an example of a susceptible host?
A reservoir such as a human and an agent such as an amoeba. The mode of transmission can include direct contact, droplets, a vector such as a mosquito, a vehicle such as food, or the airborne route. The susceptible host has multiple portals of entry such as the mouth or a syringe.
What is meant by pathogenicity?
Specifically, pathogenicity is the quality or state of being pathogenic, the potential ability to produce disease, whereas virulence is the disease producing power of an organism, the degree of pathogenicity within a group or species.
What is pathogenic disease?
Diseases in humans that are caused by infectious agents are known as pathogenic diseases. Not all diseases are caused by pathogens, other causes are, for example, toxins, genetic disorders and the host’s own immune system.
What is the other name for infectious diseases?
Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
When do you refer to infectious diseases?
Your doctor might refer you to an infectious disease specialist when: An infection is difficult to diagnose. An infection is accompanied by a high fever. A patient does not respond to treatment.
What is susceptibility disease?
​Susceptibility Susceptibility, as related to genetics, refers to the state of being predisposed to, or sensitive to, developing a certain disease. An individual’s disease susceptibility is influenced by a combination of genetic and environmental factors.
What is host in communicable disease?
A host in the context of infectious disease refers to an animal or plant that acts as a biological refuge in which another – often parasitic – organism may dwell. The host usually provides shelter or nourishment to the other organism, which may use the host to partially/completely sexually develop 1.
What is a host in infectious disease?
What is carrier host?
Carriers: hosts without obvious illness The person or animal infected can potentially spread the pathogen, but does not show clear symptoms (8). The symptoms may be mild, or may be completely absent. These hosts are called carriers, or asymptomatic carriers.
