Capillaria hepatica infection in wild brown rats (Rattus norvegicus) from the urban area of Milan, Italy.

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