Preparation of Bacterial Strains: Griffith worked with two strains of the bacterium Streptococcus pneumoniae. One was a virulent (disease-causing) strain called the S strain, which had a smooth appearance due to a polysaccharide capsule that protected it from the host's immune system. The other was a non-virulent (harmless) strain called the R strain, which lacked the capsule and had a rough appearance.
