Forty-seven wild brown rats (Rattus norvegicus) collected from the urban area of Milan (Italy) were screened for Capillaria hepatica liver infection. The liver of each rat was grossly and histologically examined for the presence of C. hepatica adults, eggs and typical C. hepatica induced lesions. In 17 rats (36%) liver lesions consistent with C. hepatica infection were detected. Grossly, white-yellow nodules of 1-5 mm in diameter were present, either scattered on the liver surface or localized in a single lobe. Histologically, granulomatous liver lesions associated with eggs and/or worms were observed. The degree of gross liver involvement was moderate in most of the positive cases (71%). About 30 cases of C. hepatica infection in humans have been documented world-wide, most of which are reported in children from 1 to 5 years of age. Our results suggest that the potential transmission of C. hepatica to children in the study area should be considered an important health issue.
