Viruses aren't alive; they can only grow and reproduce inside of the host cells they infect. Bacteria are living organisms. Both viruses and bacteria can get you very sick, but most bacteria are harmless and many are helpful.

Influenza Influenza is caused by a virus transmitted from one person to another in droplets coughed or sneezed into the air. It is characterized by cold like symptoms plus chills, fever, headaches, muscle aches, and fatigue. Most people recover completely in about a week. In addition to humans...

A viroid is A) a nonenveloped, infectious piece of RNA B) A complete, infectious virus particle C) A capsid without a nucleic acid D) a provirus E) an infectious protein A bacterial cell with lambda integrated into its chromosome i...
Translation of influenza A virus PB1-F2 occurs in a second open reading frame (ORF) of the PB1 gene segment. PB1-F2 has been implicated in regulation of polymerase activity, immunopathology, susceptibility to secondary bacterial infection, and induction of apoptosis. Experimental evidence of PB1...
Thus, we utilized a murine model of pathogenesis to discern any similarities and differences between the two morphological variants in an animal model. In addition, since previous studies have demonstrated that animals exposed to bacterial pathogens while recovering from an influenza A virus infection ...
The ubiquitin-like protein ISG15 and its conjugation to proteins (ISGylation) are strongly induced by type I interferon. Influenza B virus encodes non-structural protein 1 (NS1B) that binds human ISG15 and provides an appropriate model for determining ho

Influenza is tricky because the virus changes every year. Sometimes, the dominant strain in a flu season will be more virulent than in previous years, which can impact the number of people infected and the severity of their symptoms.
