Antibiotics and Immunity Questions

Multiple choice general knowledge science & technology

Which one of the following Antibiotic was discovered by accident?

  1. Erythromycin

  2. Penicillin

  3. Amoxylin

  4. Streptomycin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Alexander Fleming discovered penicillin accidentally in 1928 at St. Mary's Hospital, London, when he observed that Penicillium mold contaminating his petri dishes was killing staphylococcus bacteria. This serendipitous discovery revolutionized medicine and earned him the 1945 Nobel Prize.

Multiple choice general knowledge

Pencillin is obtained from?

  1. Algae

  2. fungi

  3. Synthetic Substances

  4. Synthetic Oil
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fungi is the correct answer because penicillin was first discovered in the Penicillium fungi (mold) by Alexander Fleming. It is not obtained from algae, synthetic substances, or synthetic oil. Most antibiotics are derived from fungi or bacteria, though some synthetic versions exist now.

Multiple choice general knowledge

What are friendly bacteria found in yogurt referred to:

  1. Prebiotics

  2. Probiotics

  3. Antibiotics

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Probiotics are live beneficial bacteria that promote gut health when consumed. They're found in fermented foods like yogurt, kefir, and sauerkraut. Prebiotics are non-digestible fibers that feed probiotics, while antibiotics kill bacteria (both good and bad).

Multiple choice general knowledge science & technology

zocon contains___

  1. clotrimazole

  2. Diflucan

  3. triazoles

  4. Fluconazole
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Zocon (brand name) contains Fluconazole, which is a triazole antifungal medication used to treat fungal infections. Clotrimazole is also an antifungal but is a different drug (imidazole derivative). Diflucan is actually a brand name for Fluconazole itself. 'Triazoles' refers to a class of drugs, not a specific medication.

Multiple choice general knowledge sports

Allergies can best be described as:

  1. Sneezing, Itching, watery eyes, scratchy throat.

  2. A reaction from body's immune system to a foreign substance

  3. The onset of a cold during Spring months

  4. A reaction to the influenza virus during Spring months.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Allergies are fundamentally immune system responses where the body mistakenly identifies a harmless substance (allergen) as dangerous and mounts an immune response. This distinguishes allergic reactions from infections (colds, flu) which are caused by pathogens. While symptoms like sneezing and watery eyes can occur, these are manifestations, not the definition of allergy.

Antibiotic Penicillin

  1. Alexander Fleming

  2. Guglielmo Marconi

  3. Tim Berners-Lee

  4. Elias Howe
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander Fleming discovered penicillin in 1928 when he noticed mold killing bacteria in a petri dish. This revolutionized medicine and earned him the Nobel Prize. Guglielmo Marconi invented radio, Tim Berners-Lee created the World Wide Web, and Elias Howe invented the sewing machine.

Multiple choice general knowledge science & technology

Bacterial infections in humans can be treated with what?

  1. Pathogenesis

  2. Psittacosis

  3. Antibiotics

  4. Tetratex
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Antibiotics are medications specifically designed to treat bacterial infections by killing bacteria or inhibiting their growth. Pathogenesis is the disease development process, psittacosis is a specific bacterial disease, and Tetratex is not a standard antibiotic term.

Multiple choice general knowledge

Antimicrobial resistance - also known as drug resistance - occurs when microorganisms such as bacteria, viruses, fungi and parasites change in ways that render the medications used to cure the infections they cause ineffective.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Antimicrobial resistance occurs naturally over time, usually through genetic changes in microorganisms that make them immune to medicines previously effective against them. This poses a major global threat to treating common infectious diseases.

Multiple choice general knowledge

Antimicrobial resistance - also known as medicene resistance - occurs when microorganisms such as bacteria, viruses, fungi and parasites change in ways that render the medications used to cure the infections they cause ineffective.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Despite the spelling error 'medicene' instead of 'medicine', this statement correctly describes antimicrobial resistance. Antimicrobial resistance occurs when microorganisms change and become resistant to medications that previously worked against them. The definition provided is accurate according to WHO standards.

"Scientific name of bacteria which produces first life saving antibiotic - Penicillin"

  1. Penicilium chrysogenum

  2. Penicillium Chrysogenum

  3. Penicillim chrysogenum

  4. Penicillium chrysogenum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The fungus that produces penicillin is Penicillium chrysogenum (or Penicillium notatum, but among the choices, the correct spelling is Penicillium chrysogenum). The other choices contain spelling errors in either the genus or species name.

Multiple choice

What is the name of an antibiotic that works against bacteria?

  1. Quinine

  2. Penicillin

  3. Chloroquine

  4. Anti–Tetanus Serum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Penicillin is an antibiotic obtained from the fungus ‘Penicillium notatum’ and it works against bacteria. Quinine and chloroquine are drugs which are used to treat malaria. Anti-Tetanus Serum (ATS) is a vaccine used to prevent tetanus. None of these is obtained from fungus and hence, they are not antibiotics.
