What is the name for viruses that infect bacteria? 

Your book cites several attributes that help a pathogen to invade human host tissue. Some of these invasiveness factors are  (1) how well it attaches to a host, (2) use of enzymes for entry, (3) using a vector to penetrate the host’s first line of defense, (4) inhibition of phagocytosis, and (5) acquisition of host’s resources. For three of these categories give an example. Please state the invasiveness factor first and then the specific microbe that uses that factor.
