Bacteria are intercellular organisms (i.e. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself.
-Bacteria carry all the machinery needed for their growth and multiplication. -Viruses have DNA or RNA and a protein coat; nothing else. -Viruses are not living, and need a host in order to reproduce its DNA. -The body identifies the virus as a nonliving antigen and makes antibodies to fight them.
