A Study on Some Biological, Epidemiological Features of Pancreatic Fluke Eurytrema spp in Buffalo, Cattle, Goats in the Red River Delta and Preventive Measures

Abstract

A study was conducted Ha Noi, Ha Nam, Hai Duong, Vinh Phuc province in order to identify some biological and epidemiological features of parasitic pancreatic fluke in buffalo, cattle and goats. The parasitic pancreatic fluke found in the above mentioned animal species belonged to the species
named Eurytrema pancreaticum. By necropsy, the prevalence of Eurytrema pancreaticum infection in buffalo, cattle and goats were 8.54%, 17%, 2.24%, respectively. The highest intensity of worm infection (7-71 flukes per animal) was found in cattle in Hanam. Through feces test, the highest Eurytrema spp infection incidence (24.82 %) was found in cows in Hanam. In buffalo, the highest infection incidence (20%) was noticed in Hanoi. In goats, the highest prevalence (3.33%) was observed in Vinh Phuc. E.
pancreaticum was 8.17 ± 0.12 mm in length and 4.58 ± 0.14 mm in width. E. pancreaticum eggs was 0.043 ± 0.02 mm in length and 0.031 ± 0.03 mm in width. Miracidium could be best hatched from eggs of E. pancreaticum in an environment with a pH of 7.2. It was unable to hatch miracidium in an
artificial aquatic environment. Praziquantel was shown to be very effective in treatment of E. Pancreaticum
