1
REPLICACIÓN VIRAL
2
DNA virus
1-Attachment, 2-Penetration, 3-Uncoating,
4-Synthesis (4a-Transcription, 4b-Translation,
4c-Genome replication), 5-Assembly, 6-Release
3
RNA virus
4
Retrovirus (RNA, TR)
5
VIH (RNA, TR)
6
EAV, equine arteritis virus FHV, flock house
virus HCV, hepatitis C virus KUNV, Kunjin
virus MHV, murine hepatitis virus SARS-CoV,
severe acute respiratory syndrome coronavirus
SFV, Semliki Forest virus TMV, tobacco mosaic
virus
7
Antiretrovirales
8
Bacteriofagos
3. Lisis celular y liberación de los virus
Ciclo lítico
1. Partículas virales se unen a la pared de la
célula hospedera. El DNA entra al citoplasma
celular
2. El DNA viral dirige la maquinaria celular
para producir proteínas virales y copias del DNA
viral. Se ensamblan los virus
Ciclo lisogénico
2. El DNA se integra al cromosoma bacteriano y
se convierte en profago
4. Ocasionalmente el profago sale del cromosoma
bacteriano e inicia un ciclo lítico
3. La bacteria se replica, transmitiendo el
profago a las células hijas
