ZINSER TEST BANK EXAMINATION TEST
2026 FULL QUESTIONS AND ACCURATE
SOLUTIONS GRADED A+
⩥ What four areas of study are encompassed by clinical microbiology.
Answer: Viruses, fungi, bacteria, and parasites
⩥ What is the difference between a pathogen and an opportunistic
pathogen. Answer: Pathogen: a bacteria capable of causing a disease
Opportunistic pathogen: microorganisms that invade the body and cause
illness only when the body's immune defense are impaired or absent
⩥ How do bacterial pathogens cause host damage. Answer: The damage
is caused by bacterial growth in tissues or y the toxins bacteria produce
⩥ What are the morphological types of bacteria. Answer: Coccus,
bacillus, and spirochete
⩥ What are the morphological forms of fungi. Answer: Molds and yeast
, ⩥ What is a gram stain?. Answer: A test that uses a series of stains to
differentiate the composition of their cell walls
Gram positive- violet (retain the crystal violet stain)
Gram negative- pink (lose the crystal violet and retain the safranin)
⩥ What is the difference between aerobic and anaerobic bacteria.
Answer: Aerobic bacteria grow in the presence of oxygen
Anaerobic bacteria grow in the absence or decreased levels of oxygen
⩥ How are viruses different from microorganisms? Name 3 viral
diseases. Answer: Viruses are not living cells, and can only replicate by
invading a cell, viruses can only contain either a DNA or RNA not both
Epstein-Barr virus (mono), rubella, rhinoviruses
⩥ What type of specimen is used to detect malaria and giardia. Answer:
Malaria requires blood specimen
Giardia requires fecal specimen
⩥ Five methods used to help identify bacteria. Answer: microscopic
morphology- coccus, bacillus, spirochete
colony morphology- how the colony grows on the plate
reactions with Gram stain and other stains,
biochemical reactions,
gene probes
