After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response? 

• The B-cells use this recognition to defend the body against other pathogens, such as bacteria.
•  The B-cells more quickly recognize and respond to any other virus that invades the body.
• The B-cells produce antibodies more quickly if the measles virus is encountered again.
• The B-cells transfer this recognition to T-cells, which will then devour the viruses.

Antibiotics destroy

• Bacteria
• Viruses
