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.
Virus is a microscopic organism that lives in a cell of another living thing. Although viruses are extremely small and simple, they are a major cause of disease. Some viruses infect human beings with such diseases as measles, influenza, and the common cold.Others infect animals or plants, and still others attack bacteria. Viruses produce disease in an organism by damaging some of its cells.iruses infect all kinds of plants and can cause serious damage to crops. Plant cells have tough walls that a virus cannot penetrate. But insects penetrate the cell walls while feeding on a plant and thus enable viruses to enter. Plant viruses may infect one or two leaves or an entire plant.
