Microbiology and Biochemistry Quiz

Hepatitis D Virus

• Hepatitis D virus (Delta agent) is a defective virus that can only replicate in cells already infected with Hepatitis B virus.

Anticoagulants

• All anticoagulants act by removing calcium except Heparin.

Intracellular Fluid

• The major action of intracellular fluid is related to potassium (K).

Uric Acid

• Uric acid is the end product of purine metabolism.
• It is not the major form of nitrogen excretion in man, nor is it important for the synthesis of adenine, a major component of bile, or the end point of cholesterol metabolism.

Cholesterol Esters

• Most of the cholesterol esters found in the blood are fatty acids.

Extracellular An-Ion

• The major extracellular an-ion is Chloride (Cl).

Serum Proteins

• The protein found in the highest concentration in serum is Albumin.

ASO Titer

• An elevation of the ASO titer over 200 IU in a patient's serum may indicate Acute Streptococcus pyogenes infection.

Childhood Diseases

• The causative agent of a disease with symptoms of coryza, conjunctivitis, low-grade fever, and Koplik's spots is Measles virus.

Prions

• Prions are best described as Infectious proteins with no associated nucleic acid.

Influenza Virion

• The nucleic acid of an influenza virion consists of Eight segmented single-stranded RNA genome with Negative polarity.

Interferon

• The mechanism of antiviral activity of Interferon is to Inhibit translation of Viral mRNAs.
