-
producing antibiotics
-
producing vaccines
-
producing food
-
producing biofuels
-
producing plastics

Which of the following is NOT a common way to control the growth of microbes:
-
using disinfectants
-
using sanitizers
-
using antibiotics
-
using antifungal drugs
-
using antiprotozoal drugs
E
Correct answer

Which type of hypersensitivity reaction is commonly associated with penicillin allergy?
-
Type I
-
Type II
-
Type III
-
Type IV
A
Correct answer
Explanation
Type I hypersensitivity reactions, specifically IgE-mediated reactions, are commonly associated with penicillin allergy. Upon exposure to penicillin, IgE antibodies bind to mast cells, leading to degranulation and release of inflammatory mediators, causing symptoms such as hives, swelling, and difficulty breathing.
What is the treatment for an abscess?
-
Antibiotics
-
Drainage
-
Root canal
-
Extraction
Correct answer
Explanation
The treatment for an abscess depends on the severity of the infection. Antibiotics are used to kill the bacteria that cause the infection. Drainage is used to remove the pus from the abscess. A root canal may be necessary to treat an infection in the pulp of the tooth. Extraction may be necessary if the tooth is too badly damaged to be saved.
What is the most common type of bacteria that causes dental infections?
-
Streptococcus mutans
-
Lactobacillus
-
Actinomyces
-
Porphyromonas gingivalis
A
Correct answer
Explanation
Streptococcus mutans is the most common type of bacteria that causes dental infections. This bacteria is found in plaque and can produce acids that attack the teeth and gums.
Which of the following is a common cause of infective endocarditis?
-
Staphylococcus aureus
-
Streptococcus pneumoniae
-
Escherichia coli
-
Pseudomonas aeruginosa
A
Correct answer
Explanation
Staphylococcus aureus is a common cause of infective endocarditis, a serious infection of the heart valves.
What is the treatment for infective endocarditis?
-
Antibiotics
-

Which of the following is NOT a type of antimicrobial resistance?
-
Antibiotic resistance
-
Antiviral resistance
-
Antifungal resistance
-
Antiparasitic resistance
D
Correct answer
Explanation
Antiparasitic resistance is not a type of antimicrobial resistance. Antibiotic resistance, antiviral resistance, and antifungal resistance are all types of antimicrobial resistance.
How is an abscess treated?
-
Antibiotics
-
