Which portions of a bacterial cell aid the ability of a bacterium to cause infections?

Several components of a bacterial cell aid in its ability to cause infections, including: 1. Capsules: Protect the bacterium from the host’s immune system. 2. Fimbriae and pili: Allow the bacterium to adhere to host tissues. 3. Flagella: Enable motility toward favorable environments and tissues. 4. Toxins: Produced by some bacteria to damage host cells and evade immune defenses. 5. Cell wall: The peptidoglycan layer provides structural integrity and can be a target for antibiotics.
