Descriptor islas genómicas
Entry term(s) islas de patogenicidad
islotes genómicos
Scope note: Unidades distintas de algunos GENOMAS de bacterias, bacteriófagos o plásmidos que son tipos de ELEMENTOS GENÉTICOS MÓVILES. En ellos se codifican diversos genes que facilitan la adaptación, como los FACTORES DE VIRULENCIA (en "islas o islotes de patogenicidad"), genes de RESISTENCIA A ANTIBIÓTICOS o genes necesarios para la SIMBIOSIS (en "islas o islotes de simbiosis". Su tamaño oscila entre 10 y 500 kilobases, y su CONTENIDO GC y uso de CODÓN difieren del resto del genoma. Contienen característicamente un gen INTEGRASA, aunque en algunos casos este gen ha sido eliminado, produciéndose "islas genómicas ancladas".

Scope note: Distinct units in some bacterial, bacteriophage or plasmid GENOMES that are types of MOBILE GENETIC ELEMENTS. Encoded in them are a variety of fitness conferring genes, such as VIRULENCE FACTORS (in "pathogenicity islands or islets"), ANTIBIOTIC RESISTANCE genes, or genes required for SYMBIOSIS (in "symbiosis islands or islets"). They range in size from 10 - 500 kilobases, and their GC CONTENT and CODON usage differ from the rest of the genome. They typically contain an INTEGRASE gene, although in some cases this gene has been deleted resulting in "anchored genomic islands".
