“…Protection of animals was sufficient in case of double vaccination (i.e. vaccination and revaccination) while single vaccination was less effective 17 . Sufficient protective efficacy of the live T. verrucosum vaccine in calves being vaccinated twice has been also confirmed in our study.…”

Immunity against ringworm has been well examined, but the knowledge of its development after repeated infection is limited. Therefore, the immunity developed after a single or double contact with various doses of Trichophyton verrucosum strain was investigated in calves which had or had not shown any signs of ringworm after contact with dermatophyte. In total six individual experiments were performed on 117 calves. Experimental infection with the virulent T. verrucosum strain was used to investigate the animals' immunity. Calves showing severe trichophytosis after application of high doses of T. verrucosum culture were immune to reinfection by equally high doses of this dermatophyte. A similar protection level was reached after intramuscular revaccination or after recovery from trichophytosis with moderate course induced by two inoculations of low doses. If moderate course of illness had been induced by same single dose, the immunity was lower. Animals displaying no signs of trichophytosis after inoculation with the low doses developed insufficient immunity. There was no immunity against reinfection in animals having previous contact with subinfectious doses through undamaged skin. The results obtained suggest that the level of postinfection immunity depends on the disease extent and the frequency of administration of the infectious agent. The development of postcontact immunity cannot be excluded in calves.

“…But one needs a booster vaccination for life‐long protection and the efficiency is variable. In some herds, some of the calves develop ringworm in spite of early vaccination, mostly in the period between two injections (Naess & Sandvik, 1981; Gudding & Lund, 1995; Kielstein et al ., 1998; Rybnikar et al ., 1998).…”

“…Live vaccines yielded the best results under both experimental and practical conditions (Gudding and Lund 1995). It was found that a single dose of these vaccines is not sufficient for the development of satisfactory immunity against trichophytosis; double administration of these biopreparations has to be done to obtain convenient vaccine efficacy (Rybnikář et al 1998). The interval between vaccination and re-vaccination is mostly from 10 to 14 days in registered antimycotic vaccines.…”

The aim of the study was to test a possible extension of the period between vaccination and revaccination with the live Trichoben vaccine (Bioveta, a.s., Czech Republic). The calves (n = 61) were vaccinated intramuscularly. The intervals between vaccination and re-vaccination were 3, 5, 7, 10, 14 or 28 days. Another group of calves (n = 16) was vaccinated once with a double dose of the vaccine. The protective immunity against experimental infection with a virulent Trichophyton verrucosum CCM F-650 strain was investigated in animals one month after the last vaccination and compared with a group of non-vaccinated controls (n = 16). Clinical results were evaluated and compared using balanced two-way-ANOVA. The level of post-vaccination immunity in cattle after re-vaccination was sufficient when the intervals were 5, 7, 10, 14 and 28 days. One-time injection of a double prophylactic dose of the vaccine and a 3-day interval between vaccinations reduced the immunity and vaccine efficacy to an unsatisfactory degree. There were significant differences between the groups of calves vaccinated using an interval longer than 5 days, and the group vaccinated once with a double dose, and the group with a 3-day interval between vaccinations. The level of post-vaccination immunity in cattle after re-vaccination at the commonly used interval of 10 -14 days was identical with the immunity achieved when the interval was reduced to 5 or 7 days or extended up to 28 days. The extension of the interval between vaccinations to 5 -28 days is recommended for using the Trichoben vaccine in veterinary practice.
