A case of eumycotic mycetoma with lesions in the skin, nasal cavity and lymph nodes of a cow is reported. The case history, clinical course, macroscopic and microscopic appearance of lesions, and fungal isolation are described. Drechslera rostrata was isolated from pathological tissue and Koch's postulates were satisfied on mouse inoculation. This is the first infection of its type recorded in Australia and features contrasting with cases reported in other countries are discussed.

A reduction in efficacy of abamectin and/or ivermectin against field isolates of H. contortus was identified from two farms in the New England region of New South Wales. The persistent effect of moxidectin was reduced against both isolates.
