Top definitions for ecology

Gifs
Thin branched tubules that make up the body (or mycelium) of a multicellular fungus.

The immune system
A complex network of interacting cells, cellular products, and cell-forming tissues that protects the body from pathogens and other foreign substances, destroys infected and malignant cells, and removes cellular debris: the system includes the thymus, spleen, lymph nodes, and lymphatic tissue. , stem cells, leukocytes, antibodies, and lymphokines.

Infectious disease
Penetration into the body or part of the body of a pathogenic agent, such as a microorganism or virus. Under favorable conditions, the pathogen develops or multiplies, which can lead to harmful consequences. Infection should not be confused with disease.

Inflammatory bowel disease (IBD)
A term covering a group of diseases in which the intestines become inflamed (red and swollen), probably as a result of the body's immune response to its own intestinal tissue. IBD includes Crohn's disease and ulcerative colitis.

Invasion
An ecological event characterized by the establishment of an alien organism in a new community, as well as the persistence and spread of this organism.

Koch's postulates
Koch's postulates must be fulfilled in order to assert that a specific microbe causes a specific infectious disease. These include the following: (1) the parasite occurs in every case of the disease in question and under circumstances that may explain the pathological changes and clinical course of the disease; (2) The parasite does not occur in any other diseases as an accidental and non-pathogenic parasite.; (3) After complete isolation from the organism and repeated cultivation in pure culture, the parasite can cause the disease again.

Delay
About infection - the period during which the infection is present in the host's body without causing obvious symptoms. The time that passes between a stimulus and a reaction to it.

Lysogeny
A biological process in which a bacterium is infected by a bacteriophage, which integrates its DNA into the DNA of the host, so that the host is not destroyed.

Metabolic syndrome
The name of a group of risk factors associated with obesity, such as excess weight in the middle and upper body and insulin resistance, which occur together and increase the risk of coronary heart disease, stroke and type 2 diabetes.

A metagenome
The sum of all the genes and genetic elements and their modifications in the somatic and germ cells of the host plus all the genes and genetic elements in all the microorganisms that live on or in this host at the moment. There are temporary elements in the metagenome (for example, when infected with a pathogen) and more persistent elements (for example, infection with a latent eukaryotic virus; the presence of commensal bacteria).

Metagenomics
A culture-independent method used for functional and sequence-based analysis of shared environmental (community) DNA (note that this is not the same as amplification, cloning, and sequencing of the 16S rRNA encoding gene, although metagenomic sequences [such as those created using modern sequencing techniques] can be examined for genes encoding 16S rRNA, or other phylogenetic markers).

The microbe
A microscopic living organism, such as a bacterium, fungus, protozoa, or virus.
