The pathogenesis of a disease is the mechanism biology mechanism by which the disease is caused. The term can also be used to describe the origin and development of the disease and whether it is acute medical acute , chronic medical chronic or recurrent . The word comes from the Greek language Greek pathos , disease , and genesis , creation . Types of pathogenesis include microbe microbial infection , inflammation , malignancy and Necrosis tissue breakdown . Most diseases are caused by multiple pathogenetical processes together. For example, certain cancer s arise from dysfunction of the immune system skin tumor s and lymphoma after a renal transplant , which requires immunosuppression . ref cite book last Fox first Alvin title General aspects of bacterial pathogenesis year 2010 publisher Microbiology and Immunology On line Textbook location University of South Carolina School of Medicine url http pathmicro.med.sc.edu fox bact path.htm ref Often, a potential etiology is identified by epidemiology epidemiological observations before a pathology pathological link can be drawn between the cause and the disease.

Taxobox virus group i familia Iridoviridae subdivision ranks Genera subdivision Chloriridovirus br Iridovirus br Lymphocystivirus br Megalocytivirus br Ranavirus Iridoviridae are a family of viruses all with dsDNA genomes. The family contains five genera Chloriridovirus , Iridovirus , Lymphocystivirus , Megalocytivirus , and Ranavirus . Members of the Iridoviridae family infect mainly invertebrates , but also some vertebrate species such as fish, amphibians and reptiles. The genome is 150000 280000 nt. long. They have icosohedral symmetry. The virion is made up of three domains an outer proteinaceous capsid, an intermediate lipid membrane, and a central core containing DNA protein complexes. Some of the viruses also have an outer envelope. Replication Final packaging occurs in the cytoplasm but a stage of replication also occurs in the nucleus. Virus particles enter the cell and uncoating occurs. Viral DNA then travels to the host cell nucleus and is transcribed by host RNA polymerase II modified by the virus. Meanwhile host macromolecular synthesis is stopped. Parental DNA produces a genome, which is then the template for replication in the cytoplasm. Large concatemers of viral DNA are formed by recombination in the cytoplasm. The concatamers are then packaged and the virus is released either by budding out of the cell membrane or cell lysis. Gene Expression Transcription occurs in three stages immediate early, delayed early, and late. Positive induction and negative feedback mechanisms exist in each stage, mediated by products of the other stages. Pathogenesis Little is known about the pathogenesis of iridoviruses. The pathogenesis is, however, temperature dependent and iridoviruses are thus confined to poikilothermic hosts.
