S. Safrin et L. Phan, IN-VITRO ACTIVITY OF PENCICLOVIR AGAINST CLINICAL ISOLATES OF ACYCLOVIR-RESISTANT AND FOSCARNET-RESISTANT HERPES-SIMPLEX VIRUS, Antimicrobial agents and chemotherapy, 37(10), 1993, pp. 2241-2243
We tested 23 clinical isolates of acyclovir-susceptible, acyclovir-res
istant, and foscarnet-resistant herpes simplex virus for susceptibilit
y to penciclovir. Isolates showed cross-resistance to penciclovir and
acyclovir, but penciclovir retained a relative activity against foscar
net-resistant isolates. Its clinical utility for the treatment of resi
stant herpes simplex virus infections remains to be studied.
