Gradual Changes in Genetic Based Developmentsfor Phylogenetic Trends in Picornaviruses

摘要

On the basis of the several techniques, the new groups and the strains within the Picornaviruses were classified. New groups like human pathogen EV22 (Echovirus 22) was discovered that was found to be highly different from other Picornaviruses to date. The biological properties of Picornaviruses were studied and on the basis of biological properties the viruses were classified into similar groups. The protein composition is rare because most of the copies out of 3 would not be processed to VP2 and VP4. EV23 was said to be similar to EV22 in various sections of genome. The Picornavirus classification is done hierarchically of a family using the quantitative approach with the help of PEDs (pairwise evolutionary distances). Comparison of the GENETIC classification with expert-based Picornavirus taxonomy and the differences in the frameworks were demonstrated, related to the virus groups and genetic diversity that show the classification content and structure. In the GENETIC classification, human Rhinovirus A, human Rhinovirus C and genus Aphthovirus were separated.
