The study compares infection outcomes in wild-type mice and mice with a specific gene knocked out, focusing on how different virulence factors (A, B, C) influence bacterial counts in the liver. The goal is to identify which virulence factors interact with the host's genetic makeup, leading to conclusions about their roles in the pathogen's virulence."}
