Summary:
The objective of this study was to evaluate and compare gross and histologic lesions in respiratory, renal, and hepatic systems of free-ranging sheep in two isolated volcanic environments on Hawaii Island. Tissue and fecal samples were collected in conjunction with population reductions during February 2011. Gross or histologic evidence of lungworm infection has been found in 44/49 sheep from Mauna Loa and in 7/50 sheep from Mauna Kea. Mauna Kea sheep had significantly more upper respiratory tract inflammation and hyperplasia. Environmental conditions at both locations may contribute to the lesions.
