- a Migration of juveniles through coelom to lungs doesn't cause much damage, unless certain special tissues are hit. But once they get into lungs they stimulate an inflammatory response that surrounds the pair in granular tissue - causing ulcers, bleeding, fibrosis. Eggs form granulomas. Symptoms are breathing difficulties, chronic cough, bloody sputum - and if juvis migrate to spinal cord or heart or brain they can cause paralysis, heart attack or death from granulomas.
