- Minamata disease is a form of methyl mercury poisoning caused by eating large. quantities of fish and shellfish polluted by methyl mercury in factory wastewater. It. is not a contagious disease transmitted through air or food, and it is not inherited. Minamata disease was officially discovered in 1956, and in 1968 the national govern-. ment announced that it was a pollution disease caused by the Chisso Co., Ltd. The methyl mercury that enters the body mainly attacks the central nervous.

Background Mercury in any form is poisonous, with mercury toxicity most commonly affecting the neurologic, gastrointestinal (GI) and renal organ systems. Poisoning can result from mercury vapor inhalation, mercury ingestion, mercury injection, and absorption of mercury through the skin. (See Etiology and Prognosis.) Mercury has 3 forms: (1) elemental mercury, (2) inorganic salts, and (3) organic compounds. Perhaps the most deadly form of mercury is methylmercury.

Four Big Pollution Diseases of Japan The cause of itai-itai disease was determined to be cadmium poisoning in the drinking water from the Jinzugawa River basin. The source of cadmium was discovered to be from Mitsui Mining and Smelting Company. Mitsui Mining began to discharge cadmium into the Jinzugawa River in 1910.

Mercury exposure and poisoning Symptoms of poisoning from elemental mercury. This type of poisoning is most likely to occur if there is a spill of mercury from a thermometer or other mercury-containing device. Poisoning is often caused by inhaled mercury vapour, especially in places where there is poor ventilation.

Hantavirus Pulmonary Syndrome (HPS) - Topic Overview Hantavirus pulmonary syndrome (HPS) is a lung infection caused by viruses found in the saliva, urine, and droppings of some rodents. The illness is rare but can be deadly. The first known outbreak of HPS in the United States occurred in 1993.

Methylmercury poisoning Poisoning from eating fish from water that is contaminated with methylmercury has also occurred. One such body of water is Minamata Bay in Japan. Methylmercury is used in fluorescent lights, batteries, polyvinyl chloride, and latex paint. It is a common pollutant of air and water.

- Chagas disease is spread by the triatomine bug -- nicknamed kissing bugs -- which carries the parasite Trypanosoma cruzi. Over time, the parasite can chew through cardiac muscle and cause heart failure causing an estimated 11,000 deaths globally each year. Hide Caption.

- While we are exposed to many types of mercury in our environment, the type that poses the greatest risk is methylmercury. It is the most toxic form, and it is commonly found in fish due to bioaccumulation. This occurs when mercury found in the environment is fixed by microorganisms to produce methylmercury.

Minamata, Kumamoto As of 2012, the city has an estimated population of 26,460 and a population density of 162 persons per km². The total area is 162.88 km². Minamata is known due to Minamata disease, a neurological disorder caused by mercury poisoning. The disease was discovered in 1956. A local chemical plant was blamed for causing the disease by emitting untreated wastewater to the Minamata Bay. Lately, Minamata has focused on becoming a model environmental city.

- Tuberculosis, MTB, or TB (short for tubercle bacillus), in the past also called phthisis, phthisis pulmonalis, or consumption, is a widespread, infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis.he M. tuberculosis complex (MTBC) includes four other TB-causing mycobacteria: M. bovis, M. africanum, M. canetti, and M. microti. M. africanum is not widespread, but it is a significant cause of tuberculosis in parts of Africa.

Mercury (element) Toxic effects include damage to the brain, kidneys and lungs. Mercury poisoning can result in several diseases, including acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease. Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination.ercury poisoning can be prevented (or minimized) by eliminating or reducing exposure to mercury and mercury compounds. To that end, many governments and private groups have made efforts to regulate heavily the use of mercury, or to issue advisories about its use.

Tularemia Diseases > Horse and Deer Flies > Tularemia. Tularemia. Tularemia is a disease that was first recognized as a plague-like disease of rodents in 1911 in Tulare, California. It is caused by a bacterium that is widespread in nature, occurring in a variety of wild mammals and birds, in water, and even in soil.

- Tularemia is a plague-like disease caused by the Gram-negative bacterium Francisella tularensis. The organism is transferred to man from animals (i.e., a zoonosis) such as rodents, voles, mice, squirrels, and rabbits. Reflecting the natural origin of the disease, tularemia is also known as rabbit fever.

- 1 Fish odor syndrome (trimethylaminuria) is a genetic disease; symptoms are often present from birth. 2  Fish odor syndrome is characterized by an offensive body odor and the smell of rotting fish due to the excessive excretion of trimethylaminuria (TMA) in the urine, sweat, and breath of affected individuals. Other causes of odor body can occur as a result from an excess of proteins in the diet, or from an increase in bacteria that normally produce trimethylamine in the GI tract (also may make fish odor syndrome worse); liver disease, kidney disease, poor hygiene, gingivitis, and cases of blood-borne halitosis.

Fish Odor Syndrome (Trimethylaminuria) Fish odor syndrome (trimethylaminuria) is a genetic disease; symptoms are often present from birth. Fish odor syndrome is characterized by an offensive body odor and the smell of rotting fish due to the excessive excretion of trimethylaminuria (TMA) in the urine, sweat, and breath of affected individuals. Fish odor syndrome is caused by mutations in the FMO3 gene.

- The mercury poisoning (actually thiamine deficiency and possible steatitis (inflammation of fatty tissues, symptoms are sensitivity to touch, fever and poor appetite) is often in situations where the cat is being fed ONLY tuna for prolonged periods of time. Feeding only tuna can also cause taurine deficiency.

Erethism Mad hatter disease. Mad hatter disease, or mad hatter syndrome, was an occupational disease among hatmakers, caused by chronic mercury poisoning. It affected those whose felting work involved prolonged exposure to mercury vapors. The neurotoxic effects included tremor and the pathological shyness and irritability characteristic of erethism.

African trypanosomiasis African trypanosomiasis or sleeping sickness is a parasitic disease of humans and other animals. It is caused by protozoa of the species Trypanosoma brucei. There are two types that infect humans, Trypanosoma brucei gambiense (T.b.g) and Trypanosoma brucei rhodesiense (T.b.r.).T.b.g causes over 98% of reported cases.oth are usually transmitted by the bite of an infected tsetse fly and are most common in rural areas. Initially, in the first stage of the disease, there are fevers, headaches, itchiness, and joint pains. This begins one to three weeks after the bite.

- Mercury is classified into inorganic mercury and organic mercury. Metallic mer-. cury, which is a type of inorganic mercury, is used in familiar items such as fluores-. cent lights, batteries, and thermometers. The methyl mercury which caused Minamata disease is a type of organic mer-. cury. It is a white powdery substance and smells like the sulfur in a hot spring.

- Lesson Summary. 1  Most protist diseases in humans are caused by protozoa. 2  Protozoa make humans sick when they become human parasites. 3  Trypanosoma protozoa cause Chagas disease and sleeping sickness. 4  Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.rypanosoma Protozoa. Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness, which is common in Africa. They also cause Chagas disease, which is common in South America. The parasites are spread by insect vectors.

- Methylmercury’s potential to bioaccumulate in fish makes it the form of mercury that poses the greatest. 1  risk to humans through fish consumption. Mercury occurs naturally in the environment and can enter. the environment from natural sources through the breakdown of rocks and soil and from volcanic. activity.
