Virus Defectuosos

Spanish from Spain

Descriptor	virus defectuosos
Entry term(s)	híbridos defectuosos virus incompletos
Scope note:	Virus que carecen de un genoma completo por lo que no pueden replicarse o formar una cubierta proteica. Algunos son defectuosos dependientes del huésped, lo que significa que sólo pueden replicarse en sistemas celulares que proporcionan la función genética particular de la que carecen. Otros, llamados VIRUS SATELITES, son capaces de replicarse sólo cuando su defecto genético es complementado por un virus auxiliar.

Scope note:

Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called SATELLITE VIRUSES, are able to replicate only when their genetic defect is complemented by a helper virus.
