Disease Causative Agents

In nuclear leakage, apart from the damage caused by fires and explosions, accidents also release radioactive materials which can cause radiation sickness. The radiation possesses carcinogenic potential. It will induce cancer in tissues of most species at all ages including the fetus. Nuclear waste is hazardous for tens of thousands of years.

Subramaniya Siva was a dedicated freedom fighter who suffered from leprosy, which he contracted during his imprisonment by the British.

Black leg is a bacterial disease caused by Clostridium chauvoei. It is characterized by gas accumulation (crepitus) under the skin and typically leads to sudden death.

Staph Aureus, Strep Uberis, and Klebsiella are common pathogens that cause mastitis, an inflammation of the udder. These bacteria can be contagious or environmental in origin.

Pesticides are chemical hazards, not biological ones. Biological hazards include bacteria, viruses, fungi, and parasites.

A foodborne disease outbreak is officially defined by public health agencies as two or more cases of a similar illness resulting from the ingestion of a common food.

Pathogenic bacteria can come from multiple sources: raw foods (especially meat, poultry, eggs), contaminated water, and infected people (poor hygiene, carriers). All listed sources are valid pathways for pathogen contamination.

A toxin-mediated infection occurs when a person consumes food containing live bacteria, which then produce toxins within the body, causing illness.

Norovirus is widely recognized as the leading cause of foodborne illness in the United States.

Temperature abuse, which involves keeping food in the temperature danger zone for too long, is a leading cause of foodborne illness. It allows bacteria to multiply to dangerous levels.

E.coli strains are normally present in the large intestines where they help in the production of Cyanocobalamin (Vitamin B12).

Cobra venom contains neurotoxins that primarily target the nervous system, leading to paralysis and respiratory failure by blocking nerve impulses.

Gastrointestinal diseases refer to diseases involving the gastrointestinal tract, namely the esophagus, stomach, small intestine, large intestine and rectum, and the accessory organs of digestion, the liver, gallbladder, and pancreas.

E. coli (Escherichia coli) is the name of a germ, or bacterium,that lives in the digestive tracts of humans and animals. There are many types of E. coli, and most of them are harmless. But some can cause bloody diarrhea.

Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals

Minamata disease, sometimes referred to as Chisso-Minamata disease, is a neurological syndrome caused by severe mercury poisoning. Symptoms include ataxia, numbness in the hands and feet, general muscle weakness, narrowing of the field of vision and damage to hearing and speech. Nearby anthropogenic sources, such as coal burning and mining of iron, can contaminate water sources with methylmercury, which is efficiently absorbed in the bodies of fish. Fish and shellfish concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organic compound of mercury. Minamata disease was first discovered in Minamata city in Kumamoto prefecture, Japan, in 1956. It was caused by the release of methylmercury in the industrial wastewater from the Chisso Corporation's chemical factory, which continued from 1932 to 1968. This highly toxic chemical bioaccumulated in shellfish and fish in Minamata Bay and the Shiranui Sea, which, when eaten by the local populace, resulted in mercury poisoning.

Communicable diseases are infectious diseases that can be transmitted from one person to another through various mediums, including contaminated water, food, and air.
