Disease Causative Agents

Epidemic dropsy is caused by consumption of adulterated mustard oil contaminated with sanguinarine, a toxic alkaloid from Argemone mexicana seeds. BOAA (beta-oxalylamino-L-alanine) causes neurolathyrism. Aflatoxin causes liver damage and is produced by Aspergillus flavus. Sanguinarine is the specific toxin responsible for epidemic dropsy.

The ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot tests are the primary diagnostic tests for HIV/AIDS. ELISA screens for HIV antibodies, and Western Blot confirms the positive results. These are not standard tests for cancer, leprosy, or meningitis diagnosis.

Influenza (flu) is caused by the influenza virus, not bacteria or other pathogens. The virus attacks the respiratory system. Fungi cause different infections, and amoebae are protozoa causing diseases like amoebic dysentery.

Measles is caused by the measles virus, a highly contagious RNA virus. It causes fever, rash, and respiratory symptoms. Like influenza, it is viral in origin, not bacterial, fungal, or protozoan.

RNTCP (Revised National Tuberculosis Control Programme) is India's flagship program for tuberculosis control and elimination. The program was specifically designed to combat TB through DOTS strategy, early diagnosis, and treatment. The other diseases have their own programs - malaria has NVBDCP, measles has UIP, and AIDS has NACO.

The Widal test detects Salmonella typhi antibodies in serum, diagnosing typhoid fever. It tests for agglutinating antibodies against O and H antigens, not for malaria, cholera, or dengue.

The person was affected with amoebic dysentery caused by Entamoeba histolytica.

Chaga's disease (Chagas disease) is caused by the protozoan parasite Trypanosoma cruzi, transmitted by triatomine bugs (kissing bugs). Trypanosoma gambiense causes African sleeping sickness, while the spelling 'trypanosoma bruci' appears to be a misspelling of Trypanosoma brucei.

Septicemia is the presence of bacteria or their toxins in the bloodstream, commonly referred to as blood poisoning. It is a serious systemic infection that can lead to sepsis and septic shock. It is not food poisoning (which is gastrointestinal) or a mental disorder.

Poliovirus is transmitted through the fecal-oral route, primarily via contaminated food and water. It is not transmitted through mosquito or tick bites (those are vectors for other diseases), nor through saliva and nasal secretions. Proper sanitation and vaccination have been crucial in polio eradication efforts.

Botulism is a serious illness caused by toxins produced by Clostridium botulinum bacteria. E. coli causes food poisoning, Pseudomonas causes various infections, and Salmonella causes typhoid and food poisoning, but none produce the neurotoxin that causes botulism.

Rabies is a deadly viral disease transmitted through the bite of infected animals, most commonly dogs. The virus affects the central nervous system and is almost always fatal if untreated. Diphtheria, smallpox, and malaria are transmitted through different vectors (airborne, contact, and mosquitoes respectively).

Oscillatoria is blue-green in colour, usually free-floating or entwined with other algae. It is widespread. There are approximately 150 known species of which 47 are known to occur in Australia. Some species causes contact irritation leading to severe dermatitis.

Typhoid fever is caused by Salmonella typhi bacteria and is primarily transmitted through the fecal-oral route, often via contaminated food or water. Houseflies can act as mechanical vectors, carrying the bacteria from fecal matter to food.

Rabies is a viral disease transmitted through the saliva of infected animals, most commonly through dog bites. The rabies virus attacks the central nervous system and is fatal if untreated. Beri-Beri is caused by vitamin B1 deficiency, malaria by mosquito-borne parasite, and rickets by vitamin D deficiency.
