عنوان انگلیسی Inhibition Effect of pH on the Hatchability of Fasciola Miracidia under Laboratory Conditions
چکیده انگلیسی مقاله Background: Fasciolosis, caused by the liver flukes of the genus Fasciola , is one of the most prevalent diseases of domestic livestock and human throughout the world, imposing considerable economic losses. The present study was aimed to assess the effects of different pH values on hatching rate of Fasciola miracidia . Methods: The flukes were isolated from the infected livers of the slaughtered ruminants at the abattoir of Urmia City, Iran, crushed thoroughly and sieved for isola­tion of the Fasciola eggs. The eggs were washed up several times by PBS (0.01N, pH 7.2). They were incubated at different pH values of 7±0.1 (control) and 3-9.5 (treatments) at 28°C for 16 days. Results: The maximum hatching rate was observed at pH 7 (14.93±0.65%), while no miracidia were hatched at pH 3 and/or pH 9-9.5. There were significant differences between the hatching rate of the treatments and that of the control group. Conclusion: Water pH is proven to be a crucial factor affecting the life cycle of Fasciola and its epidemiology.
