Cytotoxicity and cytopathic effects on Madin-Darby Bovine Kidney cells (×100) after addition of EO, EE and EA of Thymus capitata before infection with 103TCID 50 ml−1of Bovine herpesvirus type 1 (BHV-1). A: Cell control, not infected with BHV-1, after 72 hours of incubation. B: Virus control (cytopathic effect), untreated MDBK cell culture, 72 hours after BHV-1 infection with 103 TCID50 ml−1. C: Cytotoxic effect, MDBK treated with extracts of EO (50 μg ml−1), 72 hours of incubation. D: Viral inhibition, MDBK cells were pre-treated with EO (5 μg ml−1) for 2 h, then infected with BHV-1 at 103 TCID50 ml−1.
