Tetanus enters the body of organisms through wounds or skin breaks and can be found in manure, soil, and dust. Tetanus mechanism includes tetanus preventing the transmission of glycine and γ-aminobutyric acid from inhibitory interneurons in the spinal cord, leading to spastic paralysis. Glycine is an important amino acid that is essential for ...
Streptococcus iniae is a species of Gram-positive, sphere-shaped bacterium belonging to the genus Streptococcus.Since its isolation from an Amazon freshwater dolphin in the 1970s, S. iniae has emerged as a leading fish pathogen in aquaculture operations worldwide, resulting in over US$100M in annual losses.
Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens.
Peely has made several appearances in Fortnite merchandising. In November 2019, a Funko Pop of Peely was released. [22] Later, in 2021, Nintendo released their "Fortnite Fleet Force Bundle", which included a set of Joy-Con featuring a yellow Peely-themed controller.

Saprolegnia is generally a secondary pathogen, though in the right circumstances, it can act as primary. It most frequently targets fish, both in the wild and in tank environments. Through necrosis of the skin, Saprolegnia will spread across the surface of its host as a cotton-like film. Though it often stays in the epidermal layers, the mould ...
Noroviruses have been called “the perfect human pathogens.” They’re a type of highly contagious stomach bug that causes severe vomiting and diarrhea , along with headache, fever and body aches.
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.
Alternatively, a fish can become infected by eating an infected oligochaete. Infected tubificids can release triactinomyxons for at least a year. The triactinomyxon spores are carried by the water currents, where they can infect a salmonid through the skin. Penetration of the fish by these spores takes only a few seconds.
