Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.
Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission. The four main NCDs that are the leading causes of death globally are cardiovascular disease, cancer, chronic respiratory diseases, and diabetes.
The current list of notifiable diseases is written in the Code de la santé publique Article D3113-6 and Article D3113-7 (last revision has been made in 2012), it contains 36 diseases : 34 infectious ones and 2 non-infectious disease directly linked to the environment (Lead poisoning and Mesothelioma).
Genes have been identified that predispose disease and infection with nonpathogenic bacteria by a small number of persons. [3] Nonpathogenic Escherichia coli strains normally found in the gastrointestinal tract have the ability to stimulate the immune response in humans, though further studies are needed to determine clinical applications.
Contagious disease, a subset of infectious diseases. Cryptogenic disease, a disease whose cause is currently unknown. Disseminated disease, a disease that is spread throughout the body. Environmental disease; Lifestyle disease, a disease caused largely by lifestyle choices. Localized disease, a disease affecting one body part or area.
A secondary disease is a disease that is a sequela or complication of a prior, causal disease, which is referred to as the primary disease or simply the underlying cause . For example, a bacterial infection can be primary, wherein a healthy person is exposed to bacteria and becomes infected, or it can be secondary to a primary cause, that ...
An epizootic disease (or epizooty) may occur in a specific locale (an "outbreak"), more generally (an "epizootic"), or become widespread ("panzootic"). High population density is a major contributing factor to epizootics. The aquaculture industry is sometimes plagued by disease because of the large number of fish confined to a small area.
