Abstract

The prevalence of Austrobilharzia terrigalensis infection in the Silver Gull (Larus novaehollandiae) population of the Swan Estuary, Western Australia was shown from autopsies to be 80.7% with a median worm load of five pairs. Maximum egg-output was recorded about 3 weeks after the first eggs were voided in the faeces of experimentally-infected birds. Few worms were thought to live longer than 2-3 months. Egg-output from naturally infected L. novaehollandiae was generally low, with a median rate of 24 eggs/g for birds living within 125 km radius of Perth. The liver, duodenum and small intestine were the organs most heavily involved in A. terrigalensis infection.
