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 ...
It was formerly known as Mycobacterium balnei. [2] The strain marinum was first identified by Joseph D. Aronson in 1926 and it is observed as a pathogenic mycobacterium [3] causing tuberculosis-like infections in fish (mycobacteriosis) and skin lesions in humans. [3] [4] The bacteria grows optimal at a temperature around 30 °C. [4]
The species name is derived from the fish that it was first discovered for infecting, Stephanolepis cirrhifer. This species grows on Middlebrook 7H11 agar or egg slants after being incubated for 3–5 days at 30 °C. [1] Mycobacterium stephanolepidis has catalase activity and urease activity, intermediate for iron uptake
Fish Affected Image Symptoms Treatment Neon tetra disease: Pleistophora hyphessobryconis (Microsporidia) Neon tetras, zebrafish, various aquarium fish 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
Mycobacteroides salmoniphilum (formerly Mycobacterium salmoniphilum [2]) is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. [1] It was first identified as the causative agent of mycobacteriosis in chinook salmon and steelhead trout, [4] but has since been found to cause disease in Atlantic cod, [5] Atlantic salmon, [6] [7] burbot, [8] [9] coho ...
The surrounding egg white floats perfectly around the yolk, membrane intact. One of the divers was even able to make the egg 'dance' around by manipulating the current of the water around it.
Unlike mammals, the red blood cells of fish have DNA, and can become infected with viruses. The fish develop pale gills, and may swim close to the water surface, gulping for air. However, the disease can also develop without the fish showing any external signs of illness, the fish maintain a normal appetite, and then they suddenly die.
This nest was 111 eggs. YouTube screengrab Brandon Rahe , a contractor with the FWC’s Python Action Team, needed a boat to reach the nest, which was well hidden in a hallow of dead grass and weeds .
