Question

The term antibiotic was coined by?
A) Alexander Fleming
B) Selman Waksman
C) Louis Pasteur
D) Edward Jenner

Answer 1

Antibiotics have been used for millennia to treat infections, fact that until the only remaining century or so individuals didn't have a clue about the diseases brought about by microscopic organisms. Different forms and plant separates were utilized to treat contaminations

Complete answer:
History of Antibiotics: Antibiotics are probably the soonest developments – the old Egyptians, for instance, applied rotten bread to tainted injuries. By the twentieth century, contaminations that we currently think about directly to treat for example, pneumonia and the runs – that are brought about by microorganisms, were the main source of human demise in the created world. It wasn't until the late nineteenth century that researchers started to watch antibacterial synthetic concoctions in real life. Antibiotics are some of the earliest civilizations – the ancient Egyptians, for example, applied moldy bread to infected wounds. Until the 20th century, infections that we now consider directly to treat – such as pneumonia and diarrhea – that are caused by bacteria, were the number one cause of human death in the developed world. It wasn’t until the late 19th century that scientists began to observe antibacterial chemicals in action. Paul Ehrlich, a German physician, noted that certain chemical dyes close some bacterial cells but not others.

Antibiotic types:- Penicillin - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin. Cephalosporin - for example, cofactor, cefadroxil and cephalexin. Tetracycline - for example, tetracycline, doxycycline and lymecycline. Aminoglycosides - for example, gentamicin and tobramycin.
The word 'anti-toxins' was first utilized more than 30 years after the fact by the Ukrainian-American creator and microbiologist Selman Waksman, who in the course of his life found more than 20 anti-infection agents.

The word 'anti-toxins' was first utilized more than 30 years after the fact by the Ukrainian-American creator and microbiologist Selman Waksman, who in the course of his life found more than 20 anti-infection agents.

Hence, the option (B) is correct.

Note: Antibiotics were found by Alexander Fleming in 1928. Yet, in 1943, American microbiologist Selman Waksman (1888–1973) made the medication streptomycin from soil microscopic organisms, the first of another class of medications called aminoglycosides. The term 'anti-toxin' was instituted by Waksman to portray a substance derived from normally happening microorganisms and having antimicrobial action in high weakening.
