The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world. White spot syndrome virus (WSSV) is the lone virus of the genus Whispovirus (white spot), which is the only genus in the family Nimaviridae ...
Symptoms typically occur within 10–30 minutes of ingesting the fish and generally are self-limited. People with asthma are more vulnerable to respiratory problems such as wheezing or bronchospasms. However, symptoms may show over two hours after eating a spoiled dish. They usually last for about 10 to 14 hours, and rarely exceed one to two days.
Ciguatoxin has no taste or smell, and cannot be destroyed by conventional cooking. [2] There is no specific treatment for ciguatera fish poisoning once it occurs. [2] Mannitol may be considered, but the evidence supporting its use is not very strong. [1] Gabapentin or amitriptyline may be used to treat some of the symptoms. [2]
Symptoms typically appear within ten to 30 minutes after ingestion, and may include nausea, vomiting, diarrhea, abdominal pain, and tingling or burning lips, gums, tongue, face, neck, arms, legs, and toes. [1] Shortness of breath, dry mouth, a choking feeling, confused or slurred speech, and loss of coordination are also possible. PSP toxins ...
Symptoms of an allergic reaction to mold may include sneezing, a runny nose, or an itchy throat, according to Mayo Clinic. Ingesting large doses of certain mycotoxins can cause acute poisoning or ...
The shrimp-farming industry has developed several broodstocks of both P. stylirostris and P. vannamei that are resistant against IHHN infection. [1] The disease is caused by a single-stranded DNA virus of the species Decapod pestylhamaparvovirus 1, earlier known as IHHN virus, the smallest of the known penaeid shrimp viruses (22 nm). [2]
Necrotising hepatopancreatitis (NHP), is also known as Texas necrotizing hepatopancreatitis (TNHP), Texas pond mortality syndrome (TPMS) and Peru necrotizing hepatopancreatitis (PNHP), [1] is a lethal epizootic disease of farmed shrimp. It is not very well researched yet, but generally assumed to be caused by a bacterial infection.
Retrospective studies have suggested a case of Taura syndrome might have occurred on a shrimp farm in Colombia as early as 1990 and the virus was already present in Ecuador in mid-1991. Between 1992 and 1997, the disease spread to all major regions of the Americas where whiteleg shrimp (Litopenaeus vannamei) is cultured. The economic impact of ...
