Question

Which of these bacteria displays most capsular antigenic shift?
A)Streptococcus pneumoniae
B)Escherichia coli
C)Haemophilus influenzae
D)Streptococcus pyogenes
E)Neisseria gonorrhoeae.

Accepted Answer

Streptococcus pneumoniae is known for its ability to undergo capsular antigenic shift, which allows it to evade the immune system by changing its capsular polysaccharide antigens. This characteristic is a key factor in its virulence and ability to cause recurrent infections.
