Antibiotic, chemical substance produced by a living organism, generally a microorganism, that is detrimental to other microorganisms. Antibiotics came into worldwide prominence with the introduction of penicillin in 1941. Since then they have revolutionized the treatment of bacterial infections.
Antibiotics Definition. Antibiotics can be defined as a type of antimicrobial drug which is used for the treatment and prevention of bacterial infections by inhibiting the growth of the bacteria. They are not effective when used for diseases caused by viruses, for example, cold or flu. Viruses are infectious agents which live in the cells of.
Short Essay on Antibiotics. Article shared by. The invention of antibiotics has proved to be a boon a boon to society. The credit of invention goes to Sir Alexander Fleming whose careful observations in 1928 resulted in the invention of antibiotics. Antibiotics are chemical substances produced by various species of micro-organisms and other living systems, which are capable in small.

An antibiotic is a type of antimicrobial substance active against bacteria.It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity.
The following is a list of antibiotics.The highest division between antibiotics is bactericidal and bacteriostatic.Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior. In practice, both can effectively treat a bacterial infection.
Over use of antibiotics may relate to misinformation or misunderstanding about which infections benefit from the use of an antibiotic. For example, if a patient suffers from a common cold and is experiencing a slight throat irritation, the wise decision would be to decline antibiotic use and try other forms of cold medications like Tylenol or Motrin. What people don't realize is that viruses.
Antibiotics fight infection caused by bacteria.Patients might need different types or different amounts of antibiotics depending on what bacteria is causing their health problems. Because of this, antibiotics should always be used under the supervision of a medical doctor (or other certified medical practitioner). The doctor can also watch for side effects and change the patient's treatment.
The result of laboratory testing for the sensitivity of an isolated bacterial strain to different antibiotics. It is by definition an in vitro sensitivity. Antibiotic. Class of substances that can kill or inhibit the growth of some groups of microorganisms. Originally antibiotics were derived from natural sources (e.g., penicillin from molds), but many currently used antibiotics are semisynth.
ANTIBIOTICS. Definition: usually defined as a chemical produced by one microorganism that is capable of killing or inhibiting the growth of other microorganisms. 4 genera capable of producing natural antibiotics: Penicillium - terrestrial mold. Cephalosporium - marine mold. Bacillus - bacteria. Streptomyces - bacteria. General considerations concerning antibiotics: 1. Making new and.
Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from spreading. But they do not work for everything. Many mild bacterial infections get better on their own without using antibiotics. Antibiotics do not work for viral infections such as colds and flu, and most coughs and sore throats. Antibiotics are no longer.
Antibiotics in the water environment primarily originate from industrial wastewater, medical antibiotics, and veterinary antibiotics, and antibiotics in aquaculture accounted for a large proportion of the antibiotics. The phenomenon of antibiotic abuse in aquaculture has existed for several years. Even trace amounts of antibiotics could cause serious and potential harm to the body due to.
