What Is The Reservoir Host? reservoir host. Type:Term. Definitions. 1. the host of an infection in which the infectious agent multiplies and/or develops, and on which the agent depends for survival in nature; the host essential for the maintenance of the infection during times when active transmission is not occurring.

- Opportunistic pathogen. Definition. noun, plural: opportunistic pathogens. An infectious microorganism that is normally a commensal or does not harm its host but can cause disease when the host’s resistance is low.Supplement. Examples of opportunistic pathogens are: 1  Candida albicans-a causal agent of opportunistic oral and genital infections in human.pportunistic pathogen. Definition. noun, plural: opportunistic pathogens. An infectious microorganism that is normally a commensal or does not harm its host but can cause disease when the host’s resistance is low.

- Most Viral Host Ranges Are Narrow. The fact that the host range — the group of cell types that a virus can infect — is generally restricted serves as a basis for classifying viruses. A virus that infects only bacteria is called a bacteriophage, or simply a phage.

What is a vector? a host? A vector is an agent that transmits a bacteria, virus, parasite, etc. from a source to the host. An example is the mosquito as the vector of malaria. A host is an organism that carries another in a parasitic or symbiotic relationship . An example is that if a cat has tapeworms, the cat is the host to the tapeworms. A vector is an organism that carries a parasite or pathogen to the host.

- Infectious disease requires an agent and a mode of transmission (or vector). A good example is malaria, which is caused by Plasmodial parasites, chiefly Plasmodium falciparum but does not affect humans unless the vector, the Anopheles mosquito, is around to introduce the parasite into the human bloodstream.n 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.

- The invasion of a host by a pathogen may be aided by the production of bacterial extracellular substances which act against the host by breaking down primary or secondary defenses of the body. Medical microbiologists have long referred to these substances as invasins.

- without any means of locomotion. After encountering a host, the virus particle must pass through physical host defenses, such as dead skin, mucous layers, and the extracellular matrix. Host defenses such as antibodies and immune cells, which exist to combat virus infections, are not found in cultured cells.

- For example, allergens (such as pollen), proteins from transplanted tissues and organs, and parts of microorganisms (such as coat, capsule, cell wall, flagella, fimbria, or toxin of bacteria, viruses, etc .) can serve as antigens.ord origin: French exogene: Exogène greek -, exō - (exo) + Outside-french, - gene (gène, gen) + yielding.

Infection Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics.

Taenia solium Economic Importance for Humans: Negative. Taenia solium is one of the most dangerous tapeworms to humans, because humans can act as a definitive and intermediate host. The condition where a human is used as a definitive host for an adult tape worm is called taeniasis.This condition is usually asymptomatic in humans and nonfatal.aenia solium is different than other species in the genus Taenia in that it can use its definitive host (human) as an intermediate. The oncosphere larva can infect a human host through external autoinfection, where eggs expelled through fecal matter are ingested orally.

Section 10: Chain of Infection Portal of entry. The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use the same portal to enter a new host that they used to exit the source host.

Exotoxin An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism. They are highly potent and can cause major damage to the host. Exotoxins may be secreted, or, similar to endotoxins, may be released during lysis of the cell.

Micro bio Flashcards When the agent is introduced to a healthy, susceptible host, the host must get the disease. 4. The same agent must be found in the diseased experimental host. (When cultured and compared should be the same) (has limitations: cannot be used to demonstrate all kinds of diseases)

- The host response to VZV is critical to the outcome of primary VZV infection. The maintenance of immune memory to the virus is required to prevent symptomatic re-infection on exogenous re-exposure to VZV and to prevent symptomatic reactivation of endogenous virus.

reservoir host reservoir host, a nonhuman host that serves as a means of sustaining an infectious organism as a potential source of human infection. Wild monkeys are reservoir hosts for the yellow fever virus, which can spread from the jungle to infect humans.
