Lungworm ( Otostrongylus circumlitus ) infections in ringed seals ( Phoca hispida ) from eastern Arctic Canada
Otostrongylus circumlitus, a metastrongyloid nematode found in the lungs of ringed seals (Phoca hispida) and other pinnipeds, may affect the health of seals and reduce diving capacity. Of five sites sampled in eastern Arctic Canada (190 seals examined), Salluit, Que., is an important enzootic zone (...
