| Abstract: | The diffusion of F. hepatica in the cattle of the Novara Province was studied by means of a necroscopic survey on 2184 regularly slaughtered animals and a copro-microscopic survey on 5063 feaces samples picked up from 162 breedings farms. The 28.40% of the slaughtered animals resulted infected with F. hepatica. The parasite also resulted present in 52.74% of the examined breeding farms. A large diffusion of Paramphistomum sp. was shown, too. The diffusion areas of these Trematodes may be seen in the figures 1, 3, 6 and 7. |
