Antibiotics are mostly obtained from bacteria and fungi. These microorganisms naturally produce antibiotics as a defense mechanism against other microbes. From bacteria, a variety of antibiotics like streptomycin, tetracycline, and erythromycin are derived. Similarly, fungi, such as Penicillium, produce penicillin, one of the first and most widely used antibiotics. Antibiotics from these sources have been instrumental in treating various bacterial infections in humans and animals. Research and development in microbiology have led to the discovery of many antibiotics that have revolutionized medicine and increased life expectancy. While most antibiotics come from bacteria and fungi, some plant-derived compounds also exhibit antimicrobial properties, but they are less common in mainstream antibiotic use. The continuous search for new antibiotics from natural sources remains crucial in combating antibiotic-resistant bacteria and emerging infectious diseases.

Food poisoning is caused by Clostridium botulinum, Salmonella typhosa, and Bacillus anthracis. Clostridium botulinum produces a toxin causing botulism, a severe form of food poisoning from improperly processed foods. Salmonella typhosa is known for causing typhoid fever, but some strains can also lead to foodborne illnesses. Contaminated foods such as poultry, eggs, and unwashed produce can carry Salmonella. Bacillus anthracis causes anthrax and is not typically associated with food poisoning; however, under certain conditions, it can contaminate food and cause severe illness. While Clostridium tetani causes tetanus, it is unrelated to food poisoning. Proper food handling, cooking, and storage are crucial to prevent foodborne illnesses caused by these bacteria. Prompt medical attention and appropriate antibiotics are essential for managing infections caused by these bacteria.
The bacterium that causes tuberculosis (TB) is Mycobacterium. The specific species responsible for TB is Mycobacterium tuberculosis. This bacterium primarily affects the lungs, causing pulmonary tuberculosis, but it can also affect other parts of the body in extrapulmonary forms of the disease. M. tRead more
The bacterium that causes tuberculosis (TB) is Mycobacterium. The specific species responsible for TB is Mycobacterium tuberculosis. This bacterium primarily affects the lungs, causing pulmonary tuberculosis, but it can also affect other parts of the body in extrapulmonary forms of the disease. M. tuberculosis is a slow-growing, rod-shaped bacterium with a waxy cell wall that makes it resistant to many disinfectants and antibiotics. TB spreads through the air when an infected person coughs or sneezes, releasing bacteria-laden droplets. Early detection and appropriate antibiotic treatment are essential to managing and controlling TB. In addition to Mycobacterium tuberculosis, other related species like Mycobacterium bovis can also cause tuberculosis, particularly in animals. The development of the BCG vaccine and advances in antibiotic therapy have significantly reduced TB incidence and mortality rates worldwide.

The bacteria found in the human intestine is Escherichia coli. E. coli is a common bacterium that resides in the lower intestine of humans and other warm-blooded animals. It plays an essential role in the gut by aiding in digestion, synthesizing vitamins like vitamin K, and maintaining a healthy balance of gut flora. Most strains of E. coli are harmless and beneficial, contributing to the proper functioning of the digestive system. However, some pathogenic strains can cause foodborne illnesses and infections. Despite these exceptions, E. coli is a key part of the natural gut microbiota. It helps protect the intestine from colonization by harmful pathogens and supports the immune system. Research on E. coli has also contributed significantly to the fields of genetics and microbiology.
Bacteria are not able to survive in pickles with excess salt because their protoplasms get shrunk and thus die. This occurs due to the high osmotic pressure caused by the excess salt in the pickles.

Bacteria are not able to survive in pickles with excess salt because their protoplasms get shrunk and thus die. This occurs due to the high osmotic pressure caused by the excess salt in the pickles. When bacteria are in a salty environment, water inside their cells moves out to balance the concentration difference between the inside and outside of the cell. This leads to dehydration and shrinking of the bacterial cells, which disrupts their cellular functions and ultimately causes them to die. The high salt concentration acts as a natural preservative by inhibiting the growth of bacteria and other microorganisms, thereby extending the shelf life of pickles and other salty foods. This method of preservation has been used for centuries to prevent spoilage and maintain the quality of food products.
