Blood T6-lymphocyte antigen levels as a poor resistance marker in ovine dermatophilosis

Abstract Merino ewes lambs from a flock expected to have a high prevalence of dermatophilosis were examined for lesions at marking, weaning and prior to first shearing. Blood was collected at marking and prior to shearing to enable quantification of T6-lymphocyte antigen levels in peripheral blood mononuclear cells (PBM) using monoclonal antibody SBU-T6 20–27. A group of the lambs that had persistent and/or severe dermatophilosis had significantly lower ( P
