Streptomycin was isolated by Waxman. It was discovered in 1943 by Selman Waksman and his team at Rutgers University. Their work involved screening soil microorganisms for antimicrobial activity, leading to the isolation of streptomycin from Streptomyces griseus. This groundbreaking discovery marked a major advancement in the treatment of tuberculosis, as streptomycin became the first effective antibiotic against the disease. Waksman’s research on antibiotics earned him the Nobel Prize in Physiology or Medicine in 1952, recognizing his contributions to medicine and microbiology. Streptomycin’s introduction revolutionized tuberculosis therapy, significantly reducing mortality rates associated with the disease. It also paved the way for the development of other antibiotics and antibiotics research, shaping the landscape of modern medicine. The discovery of streptomycin underscored the importance of natural products and microbial diversity in drug discovery, inspiring further exploration of microbial sources for novel therapeutic agents.
Tikka disease occurs in groundnut. It is caused by the fungus Cercospora arachidicola. This fungal pathogen infects groundnut plants, causing characteristic dark brown to black lesions on leaves, stems, and pods. Tikka disease can lead to reduced yields and quality in groundnut crops. The fungus surRead more
Tikka disease occurs in groundnut. It is caused by the fungus Cercospora arachidicola. This fungal pathogen infects groundnut plants, causing characteristic dark brown to black lesions on leaves, stems, and pods. Tikka disease can lead to reduced yields and quality in groundnut crops. The fungus survives in infected plant debris and soil, and its spores are spread by wind, rain, and mechanical means. Warm and humid conditions favor disease development, making it a significant concern in regions where groundnut is cultivated. Management strategies for Tikka disease include planting disease-resistant varieties, practicing crop rotation, removing and destroying infected plant debris, and applying fungicides as necessary. Integrated disease management approaches, including cultural, biological, and chemical control methods, are often employed to minimize the impact of Tikka disease on groundnut production and ensure the sustainability of groundnut cultivation in affected regions.
AIDS is caused by [D] Virus. Specifically, it is caused by the Human Immunodeficiency Virus (HIV), which attacks the immune system, leading to Acquired Immunodeficiency Syndrome (AIDS).

AIDS is caused by [D] Virus. Specifically, it is caused by the Human Immunodeficiency Virus (HIV), which attacks the immune system, leading to Acquired Immunodeficiency Syndrome (AIDS). HIV primarily targets CD4 cells, weakening the immune system and increasing susceptibility to infections and certain cancers. Unlike bacteria [A], fungi [B], or worms [C], which can cause various diseases, AIDS specifically results from HIV infection, transmitted through blood, semen, vaginal fluids, and breast milk. Effective antiretroviral therapy (ART) can manage HIV, but there is currently no cure, making prevention crucial in controlling the spread of the virus.
People who drink heavy amounts of alcohol often die due to [C] Cirrhosis. Prolonged alcohol consumption damages the liver, leading to cirrhosis, where scar tissue replaces healthy liver tissue, impeding liver function and causing complications such as portal hypertension and liver failure. While alcRead more
People who drink heavy amounts of alcohol often die due to [C] Cirrhosis. Prolonged alcohol consumption damages the liver, leading to cirrhosis, where scar tissue replaces healthy liver tissue, impeding liver function and causing complications such as portal hypertension and liver failure. While alcohol abuse can increase the risk of certain cancers, such as liver cancer [B], and cardiovascular issues, including cardiac arrest [D], cirrhosis remains one of the most significant health risks associated with heavy alcohol intake. Effective interventions to reduce alcohol consumption are crucial in preventing the development and progression of cirrhosis and related complications.
Simple goiter is the disease affecting the [D] Thyroid gland. It involves the abnormal enlargement of the thyroid gland, typically due to iodine deficiency, which impairs thyroid hormone synthesis.

Simple goiter is the disease affecting the [D] Thyroid gland. It involves the abnormal enlargement of the thyroid gland, typically due to iodine deficiency, which impairs thyroid hormone synthesis. This condition can lead to a visible swelling in the neck area, causing difficulty swallowing or breathing. Simple goiter does not affect the gums [A], tear gland [B], or liver [C]. Adequate dietary iodine intake is crucial for preventing simple goiter, although other factors such as genetic predisposition or certain medications may also contribute to its development. Treatment may involve iodine supplementation or thyroid hormone replacement therapy.
