Abstract:
The protective efficacy of two Czech vaccines against bovine Trichophyton verrucosum infection after double vaccination of calves in prophylactic doses, with an interval of 13 days between vaccination and revaccination, was very good. When these preparations were applied in a double dose only once, less protective effect was produced. The use of 0.5% aluminium hydroxide to dilute the vaccines had no influence on the effect of single vaccination.
