MIC 205 REAL ACCURATE EXAM QUERIES WITH REVISED
ANSWERS NEW (2025-2026)
Which statement is completely true about Mycobacteria when they are stained
using Acid-fast staining?
carbolfuchsin is trapped in the mycolic acid, making Mycobacteria fuschia
Which of the following is NOT true about the two major categories of bacteria?
Consists of Bacteria and Archaea
Which of the following statements is NOT true about Archaea?
has a cell wall with peptidoglycan
Which of the following statements is true about Staphylococcus aureus?
Staphylo stands for clustered arrangement
Which of the following statements is true about Streptococcus pyogenes
(GAS)?

Gram stains on stool specimens from the child and from the cattle revealed
pink, rod-shaped bacteria and the clinician suspected Escherichia coli and
wanted to determine the serovar. Testing reveals that the bacterium has an O-
polysaccharide number 157 and flagellar antigen 7.
The two tests help reveal, in this case, what serovar of Escherichia coli is
causing this child's infection
Gram negative cell walls:
all of the above are true
Short external structures made of microtubules and used for movement in some
unicellular eukaryotic cells are:
cilia
Which of the following is an organelle and most closely resembles a prokaryotic
