Effects of physiologic concentrations of l-lysine on in vitro replication of feline herpesvirus 1.

Objective: To evaluate the effects of various concentrations of l-lysine on in vitro replication of feline herpesvirus 1 (FHV-1).

Sample: Cultures of Crandell-Rees feline kidney (CRFK) cells.

Procedures: CRFK cells were inoculated with FHV-1 and maintained in media with 20 combinations of l-arginine and l-lysine concentrations.
