Vedclass · Answer

(B) In Frederick Griffith's transformation experiment,the $S$ strain (smooth strain) of Streptococcus pneumoniae is virulent because it possesses a polysaccharide coat (capsule) that protects it from the host's immune system. When a live $S$ strain is injected into a mouse,it causes the development of pneumonia,leading to the death of the mouse. Conversely,the $R$ strain (rough strain) lacks this capsule and is non-virulent.

What happens if a live $S$ strain of Streptococcus pneumoniae is injected into a mouse?
