The results of mapping of genetic determinants for poliovirus attenuation are reviewed. Possible mechanisms of the phenotypic expression of attenuating mutations located in different regions of the viral genome are discussed.

UI	MeSH Term	Description	Entries
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D010641	Phenotype	The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.	Phenotypes
D011054	Poliovirus Vaccine, Inactivated	A suspension of formalin-inactivated poliovirus grown in monkey kidney cell tissue culture and used to prevent POLIOMYELITIS.	Salk Vaccine,Inactivated Poliovirus Vaccine,Vaccine, Inactivated Poliovirus,Vaccine, Salk
D005814	Genes, Viral	The functional hereditary units of VIRUSES.	Viral Genes,Gene, Viral,Viral Gene
D005818	Genetic Engineering	Directed modification of the gene complement of a living organism by such techniques as altering the DNA, substituting genetic material by means of a virus, transplanting whole nuclei, transplanting cell hybrids, etc.	Genetic Intervention,Engineering, Genetic,Intervention, Genetic,Genetic Interventions,Interventions, Genetic
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014613	Vaccines, Attenuated	Live vaccines prepared from microorganisms which have undergone physical adaptation (e.g., by radiation or temperature conditioning) or serial passage in laboratory animal hosts or infected tissue/cell cultures, in order to produce avirulent mutant strains capable of inducing protective immunity.	Attenuated Vaccine,Vaccines, Live, Attenuated,Attenuated Vaccines,Vaccine, Attenuated
D017955	Poliovirus	A species of ENTEROVIRUS which is the causal agent of POLIOMYELITIS in humans. Three serotypes (strains) exist. Transmission is by the fecal-oral route, pharyngeal secretions, or mechanical vector (flies). Vaccines with both inactivated and live attenuated virus have proven effective in immunizing against the infection.
