Mycobacterium marinum is an acid-fast, aerobic bacterium which can infect humans. [4] Infection is usually associated either with swimming, preparing sea food, or with keeping or working with aquarium fish. [2] Infections of humans are rare due to the chlorination of water. [4]
Like humans and other animals, fish suffer from diseases and parasites.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.
Heavily infected fish appear emaciated and lethargic. Infection targets skeletal muscle, which will appear more opaque through the skin. Piscine tuberculosis: Mycobacterium marinum bacteria: All: Weight loss evident on underparts, with corresponding loss of appetite, papules, discoloration and bulging eyes. Amputation Fin rot: Bacterial or ...
The bacteria can cause either acute septicaemia or chronic encephalitis in infected fish. Outbreaks normally occur in spring and autumn. Outbreaks normally occur in spring and autumn. Edwardsiella ictaluri can be found in Asia and the United States , being of particular economic importance in the U.S.
Vibrio parahaemolyticus (V. parahaemolyticus) is a curved, rod-shaped, Gram-negative bacterial species found in the sea and in estuaries which, when ingested, may cause gastrointestinal illness in humans. [1] V. parahaemolyticus is oxidase positive, facultatively aerobic, and does not form spores.
Aquarium granuloma (also known as fish tank granuloma and swimming pool granuloma) is a rare skin condition caused by a non-tubercular mycobacterium known as Mycobacterium marinum. [2] Skin infections with M. marinum in humans are relatively uncommon, and are usually acquired from contact with contaminated swimming pools, aquariums or infected ...
Edwardsiella tarda is a member of the family Hafniaceae. [1] [2] The bacterium is a facultatively anaerobic, small, motile, gram negative, straight rod with flagella.[1] [2] Infection causes Edwardsiella septicemia (also known as ES, edwardsiellosis, emphysematous putrefactive disease of catfish, fish gangrene, and red disease) in channel catfish, eels, and flounder.
Aeromonas hydrophila is not as pathogenic to humans as it is to fish and amphibians. One of the diseases it can cause in humans, gastroenteritis, occurs mostly in young children and people who have compromised immune systems or growth problems. This bacterium is linked to two types of gastroenteritis.
