Understanding the difference between otitis media with effusion and other forms of middle ear infection is important. Otitis media is a generic term defined as an inflammation of the middle ear without reference to a specific etiology or pathogenesis.
Scientists have long sought to uncover the structure and function of viruses. Viruses are unique in that they have been classified as both living and nonliving at various points in the history of biology. Viruses are particles that are capable of causing a number of diseases including cancer.
A virus is a small, infectious agent that is made up of a core of genetic material surrounded by a shell of protein. The genetic material (which is responsible for carrying forward hereditary traits from parent cells to offspring) may be either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA).n order to produce new copies of itself, a virus must use the host cell's reproductive machinery.. The newly made viruses then leave the host cell, sometimes killing it in the process, and proceed to infect other cells within the organism.
