Question

Some bacteria have a slimy coat around them, like a greased pig effect, these structures are called _______ and can be a problem for the body to kill since WBC's often slip off them when they go to engulf them.

1) capsules
2) flagella
3) pili
4) cell walls

Answer 1

The slimy coat around some bacteria is known as a capsule, which can hinder white blood cells' ability to engulf the bacteria due to its protective properties.

Step-by-step explanation:

The slimy coat around some bacteria is called a capsule, which can indeed be problematic for the body as it protects the immune system. White blood cells often slip off the capsules when attempting to engulf and destroy these bacteria. Other virulence factors produced by pathogens include proteases, mycolic acid, and M protein. Structures such as fimbriae or pili assist in attachment and genetic material transfer, and flagella are used for locomotion. The capsule not only helps bacteria evade the immune system but also allows them to adhere to surfaces and form biofilms, contributing to their virulence.
