Risk Group 2• RG2:– Agents associated with human disease– rarely serious– preventive or therapeutic interventions available• Examples:– E. coli (pathogenic strains)– Adenovirus (used as rep-deficient viral vector)– Moloney murine retrovirus, amphotropic– Herpes simplex virus (used as rep-deficient viral vector)– Chicken pox“Ecotropic Pathogens”“Amphotropic Pathogens”
cont.• “Ecotropic” viruses infect only specific host species.• “Amphotropic” viruses can infect multiple speciesincluding humans.• Modifying the envelope protein: extend host rangeof some viral vectors• Ecotropic murine retrovirus is RG1 while anamphotropic murine retrovirus is RG2.
