Nitric acid test and paper chromatography test are used in the detection of argemone oil.Paper chromatography test is the most sensitive test.

Withdrawal of the contaminated cooking oil is the most important initial step. Bed rest with leg elevation and a protein-rich diet are useful. Supplements of calcium, antioxidants (vitamin C and E), and thiamine and other B vitamins are commonly used. Corticosteroids and antihistaminics such as promethazine have been advocated by some investigators, but demonstrated efficacy is lacking. Diuretics are used universally but caution must be exercised not to deplete the intravascular volume unless features of frank congestive cardiac failure are present, as oedema is mainly due to increased capillary permeability. Cardiac failure is managed by bed rest, salt restriction, digitalis and diuretics. Pneumonia is treated with appropriate antibiotics. Renal failure may need dialysis therapy and complete clinical recovery is seen. Glaucoma may need operative intervention, but generally responds to medical management.

Recently published evidence suggest heat stress and strenuous activity-induced cyclic uricosuria and crystalluria as a possible mechanism for the tubular lesion.

To date, CKDu (MeN) causes remain undetermined and debatable; nevertheless the number of cases could lead to the application of a precautionary principles from a humanitarian perspective. Due to the fact that the Mesoamerican nephropathy is regarded as a multifactorial disease the experimental design of comparative study should take following logical setting into account.

Multifactorial problem. Assume that a disease is definitely caused by A,B,C. The disease will develop if at least 2 risk factors are present in a certain region.

- formula_1 no prevalence of disease in region 1

- A no prevalence of disease in region 2

- B no prevalence of disease in region 3

- C no prevalence of disease in region 4

- A,B prevalence of disease in region 5

- B,C prevalence of disease in region 6

- C,A prevalence of disease in region 7

- A,B,C prevalence of disease in region 8

Removing the risk factor A in the experimental group in comparison to control group will lead to changes in the outbreak of the disease in only 2 of 8 combinatorically possible regions, even if we define A as a relevant risk factor in this theoretical setting. The same is true if the experimental design adds in a comparative study the risk factor A to the regions in the experimental group in comparison to the control group.

If the difference in experimental and control are 2 risk factors (adding or removing two risk factor e.g. A,B in the control group), then 4 regions will show a differences in prevalence of the disease, with the disadvantage that the experimental design cannot clarify if one or both risk factors A and B are contributing to the progression and prevalence of the disease.

Beside this logical analysis of a multifactorial setting there is space for further investigation, e.g.: Leptospirosis has been suggested as a possible contributing factor and oceanic nephrotoxic algae or agents have also been brought to the chart of possibilities as a culprit for this unusual form of kidney damage..

Assessment of the mentioned risk factors and their possible synergism will depend on more and better research.

In some cases the causes of an infection or disease will be obvious (such as fin rot), though in other cases it may be due to water conditions, requiring special testing equipment and chemicals to appropriately adjust the water. Isolating diseased fish can help prevent the spread of infection to healthy fish in the tank. This also allows the use of chemicals or drugs which may damage the nitrogen cycle, plants or chemical filtration of a properly-functioning tank. Other alternatives include short baths in a bucket that contains the treated water. Salt baths can be used as an antiseptic and fungicide, and will not damage beneficial bacteria, though ordinary table salt may contain additives which can harm fish. Alternatives include aquarium salt, Kosher salt or rock salt. Gradually raising the temperature of the tank may kill certain parasites, though some diseased fish may be harmed and certain species can not tolerate high temperatures. Aeration is necessary since less oxygen is dissolved in warm water.

There are a number of effective treatments for many stains of bacterial infections. Three of the most common are tetracycline, penicillin and naladixic acid. Salt baths are another effective treatment.

Disease cures are almost always more expensive and less effective than simple prevention measures. Often precautions involve maintaining a stable aquarium that is adjusted for the specific species of fish that are kept and not over-crowding a tank or over-feeding the fish. Common preventive strategies include avoiding the introduction of infected fish, invertebrates or plants by quarantining new additions before adding them to an established tank, and discarding water from external sources rather than mixing it with clean water. Similarly, foods for herbivorous fish such as lettuce or cucumbers should be washed before being placed in the tank. Containers that do not have water filters or pumps to circulate water can also increase stress to fish. Other stresses on fish and tanks can include certain chemicals, soaps and detergents, and impacts to tank walls causing shock waves that can damage fish.

By the time a disorder reaches the point of causing dropsy, it can often be fatal and at the very least the fish is very ill and requires immediate quarantine and treatment.

Because dropsy is a symptom of an illness, its cause may or may not be contagious. However, it is standard practice to quarantine sick fish to prevent spreading the underlying cause to the other fish in the tank community.

The condition has been found in cats, fish, herons, terrapins and Nile crocodiles, piscivores such as otters, cormorants, Pel's fishing-owls and fish eagles. The disorder is also regularly found in captive-bred animals fed on high fish diets, such as mink, pigs and poultry. It shows as a rubber-like hardening of fat reserves which then become unavailable for normal metabolism, resulting in extreme pain, loss of mobility and death.

This condition is diagnosed by detecting the bacteria in skin, blood, joint fluid, or lymph nodes. Blood antibody tests may also be used. To get a proper diagnosis for rat-bite fever, different tests are run depending on the symptoms being experienced.

To diagnosis streptobacillary rat-bite fever, blood or joint fluid is extracted and the organisms living in it are cultured. Diagnosis for spirillary rat bite fever is by direct visualization or culture of spirilla from blood smears or tissue from lesions or lymph nodes. Treatment with antibiotics is the same for both types of infection. The condition responds to penicillin, and where allergies to it occur, erythromycin or tetracyclines are used.

It is thought to be brought about by any or a combination of a number of factors which include:

- Vitamin E deficiency

- Microcystin poisoning

- Heavy metals and other pollutants such as DDT, PCBs, PCDDs and brominated flame retardants

- Ingestion of affected animals

- Pathogens as yet unidentified

The earliest known report of "bakanae" is from 1828; it was first described scientifically in 1898 by Japanese researcher Shotaro Hori, who showed that the causative agent was fungal.

The fungus affects rice crops in Asia, Africa, and North America. In epidemic cases yield losses may reach up to 20% or more. A 2003 publication from the International Rice Research Institute estimated that outbreaks of bakanae caused crop losses that were 20% to 50% in Japan, 15% in Thailand and 3.7% in India.

While obviously preventable by staying away from rodents, otherwise hands and face should be washed after contact and any scratches both cleaned and antiseptics applied. The effect of chemoprophylaxis following rodent bites or scratches on the disease is unknown. No vaccines are available for these diseases.

Improved conditions to minimize rodent contact with humans are the best preventive measures. Animal handlers, laboratory workers, and sanitation and sewer workers must take special precautions against exposure. Wild rodents, dead or alive, should not be touched and pets must not be allowed to ingest rodents.

Those living in the inner cities where overcrowding and poor sanitation cause rodent problems are at risk from the disease. Half of all cases reported are children under 12 living in these conditions.

Flacherie (literally: "flaccidness") is a disease of silkworms, caused by silkworms eating infected or contaminated mulberry leaves. Flacherie infected silkworms look weak and can die from this disease. Silkworm larvae that are about to die from Flacherie are a dark brown.

There are two kinds of flacherie: essentially, infectious (viral) flacherie and noninfectious ("bouffee") flacherie. Both are technically a lethal diarrhea.

Bouffée flacherie is caused by heat waves ("bouffée" means "sudden heat spell" in French).

Viral flacherie is ultimately caused by infection with "Bombyx mori" infectious flacherie virus (BmIFV, Iflaviridae), "Bombyx mori" densovirus (BmDNV, Parvoviridae) or "Bombyx mori" cypovirus 1 (BmCPV-1, Reoviridae). This either alone or in combination with bacterial infection destroys the gut tissue. Bacterial pathogens contributing to infectious flaccherie are "Serratia marcescens", and species of "Streptococcus" and "Staphylococcus" in the form known as thatte roga.

Louis Pasteur, who began his studies on silkworm diseases in 1865, was the first one able to recognize that mortality due to viral flacherie was caused by infection. (Priority, however, was claimed by Antoine Béchamp.) Richard Gordon described the discovery: "The French silk industry was meanwhile plummeting from a 130 million to an 8 million francs annual income, because the silkworms had all caught "pébrine," black pepper disease…He [Pasteur] went south from Paris to Alais, and rewarded them by discovering the silkworm epidemic to be inflicted by some sort of living microbe…Pasteur threw in another disease, "flâcherie," silkworm diarrhoea. The cures for both were culling the insects which showed the peppery spots — the peasants bottled the silkworm moths in brandy, for display to the experts — and rigorous hygiene of the mulberry leaf."

Treatment is symptomatic and aims to prevent dehydration in young pigs, using products such as electrolyte and energy supplements. Good biosecurity protocols such as adequate quarantine, isolation of cases, and disinfection help prevent entry or spread of the disease in the herd. In Canada, the Canadian Swine Health Board developed detailed protocols on how to adequately disinfect transportation vehicles for live hogs and ensure the quality of the disinfecttion protocol.

Zymotic disease was a 19th-century medical term for acute infectious diseases, especially "chief fevers and contagious diseases (e.g. typhus and typhoid fevers, smallpox, scarlet fever, measles, erysipelas, cholera, whooping-cough, diphtheria, &c.)".

Zyme or microzyme was the name of the organism presumed to be the cause of the disease.

As originally employed by Dr W. Farr, of the British Registrar-General's department, the term included the diseases which were "epidemic, endemic and contagious," and were regarded as owing their origin to the presence of a morbific principle in the system, acting in a manner analogous to, although not identical with, the process of fermentation.

In the late 19th century, Antoine Béchamp proposed that tiny organisms he termed "microzymas", and not cells, are the fundamental building block of life. Bechamp claimed these microzymas are present in all things—animal, vegetable, and mineral—whether living or dead . Microzymas are what coalesce to form blood clots and bacteria. Depending upon the condition of the host, microzymas assume various forms. In a diseased body, the microzymas become pathological bacteria and viruses. In a healthy body, microzymas form healthy cells. When a plant or animal dies, the microzymas live on. His ideas did not gain acceptance.

The word "zymotic" comes from the Greek word ζυμοῦν "zumoûn" which means "to ferment". It was in British official use from 1839. This term was used extensively in the English Bills of Mortality as a cause of death from 1842. Robert Newstead (1859–1947) used this term in a 1908 publication in the "Annals of Tropical Medicine and Parasitology", to describe the contribution of house flies ("Musca domestica") towards the spread of infectious diseases. However, by the early 1900s, bacteriology "displaced the old fermentation theory", and so the term became obsolete.

In her "Diagram of the causes of mortality in the army in the East", Florence Nightingale depicts The blue wedges measured from the centre of the circle represent area for area the deaths from Preventible or Mitigable Zymotic diseases ; the red wedges measured from the centre the deaths from wounds, & the black wedges measured from the centre the deaths from all other causes.

The 1951 Pont-Saint-Esprit mass poisoning, also known as Le Pain Maudit, occurred on 15 August 1951, in the small town of Pont-Saint-Esprit in southern France. More than 250 people were involved, including 50 persons interned in asylums and resulted in 7 deaths. A foodborne illness was suspected, and among these it was originally believed to be a case of "cursed bread" ("pain maudit").

Most academic sources accept ergot poisoning as the cause of the epidemic, while a few theorize other causes such as poisoning by mercury, mycotoxins, or nitrogen trichloride.

Haverhill fever (or epidemic arthritic erythema) is a form of "rat-bite fever" caused by the bacterium "Streptobacillus moniliformis", an organism common in rats and mice. Symptoms begin to appear two to ten days after a rat bite injury. The illness resembles a severe influenza, with a moderate fever (38-40 °C, or 101-104 °F), chills, joint pain, and a diffuse red rash, located mostly on the hands and feet. The causative organism can be isolated by blood culture, and penicillin is the most common treatment. Treatment is usually quite successful, although the body can clear the infection by itself in most cases. Complications are rare, but can include endocarditis and meningitis.

Despite its name, it can present without being bitten by a rat.

The disease was recognized from an outbreak which occurred in Haverhill, Massachusetts in January, 1926. The organism "S. moniliformis" was isolated from the patients. Epidemiology implicated infection via consumption of milk from one particular dairy.

Bright's disease was historically 'treated' with warm baths, blood-letting, squill, digitalis, mercuric compounds, opium, diuretics, laxatives, and dietary therapy, including abstinence from alcoholic drinks, cheese and red meat. Arnold Ehret was diagnosed with Bright's disease and pronounced incurable by 24 of Europe's most respected doctors; he designed "The Mucusless Diet Healing System", which apparently cured his illness. William Howard Hay, MD had the illness and, it is claimed, cured himself using the Hay diet.

Because the risk of meningococcal disease is increased among USA's military recruits, all military recruits routinely receive primary immunization against the disease.

Antigen detection, polymerase chain reaction assay, virus isolation, and serology can be used to identify adenovirus infections. Adenovirus typing is usually accomplished by hemagglutination-inhibition and/or neutralization with type-specific antisera. Since adenovirus can be excreted for prolonged periods, the presence of virus does not necessarily mean it is associated with disease.

Shortly after the incident, in September 1951, scientists writing in the "British Medical Journal" declared that “the outbreak of poisoning” was due to eating bread made from rye grain that was infected with the fungus. The victims appeared to have one common connection. They had eaten bread from the bakery of Roch Briand who was subsequently blamed for using flour made from rye.

Meningitis A,C,Y and W-135 vaccines can be used for large-scale vaccination programs when an outbreak of meningococcal disease occurs in Africa and other regions of the world. Whenever sporadic or cluster cases or outbreaks of meningococcal disease occur in the US, chemoprophylaxis is the principal means of preventing secondary cases in household and other close contacts of individuals with invasive disease. Meningitis A,C,Y and W-135 vaccines rarely may be used as an adjunct to chemoprophylaxis,1 but only in situations where there is an ongoing risk of exposure (e.g., when cluster cases or outbreaks occur) and when a serogroup contained in the vaccine is involved.

It is important that clinicians promptly report all cases of suspected or confirmed meningococcal disease to local public health authorities and that the serogroup of the meningococcal strain involved be identified. The effectiveness of mass vaccination programs depends on early and accurate recognition of outbreaks. When a suspected outbreak of meningococcal disease occurs, public health authorities will then determine whether mass vaccinations (with or without mass chemoprophylaxis) is indicated and delineate the target population to be vaccinated based on risk assessment.

If untreated, pellagra can kill within four or five years. Treatment is with nicotinamide, which has the same vitamin function as niacin and a similar chemical structure, but has lower toxicity. The frequency and amount of nicotinamide administered depends on the degree to which the condition has progressed.

No rapid laboratory tests are available to diagnose rickettsial diseases early in the course of illness, and serologic assays usually take 10-12 days to become positive. Research is indicating that swabs of eschars may be used for molecular detection of rickettsial infections.
