Enterocin CRL35 inhibits late stages of HSV-1 and HSV-2 replication in vitro
The replication of herpes simplex virus (HSV) type 1 and 2 in Vero cells is inhibited in the presence of enterocin CRL35 (ECRL), a bacteriocin produced by Enterococcus faecium CRL35. Attempts to resolve the mode of action of ECRL indicate that virus adsorption and penetration are not affected. Inste...
