[The effectiveness of LTF 130 Trichophyton vaccine under field conditions]

Abstract

The preventive action of ringworm vaccine LTF 130 was studied in calves. A number of these calves were found to develop ringworm despite vaccination when they came into contact with infected animals during the build-up of immunity. The incidence of ringworm was reduced when the animals were vaccinated at an early age or when the dosage was increased on vaccination later in life.
