Abstract


Researches to determine the infectious statue on the pancreatic fluke, Eurytrema pancreaticum(Janson 1889) Looss, 1907, were made into several slaughter hauses at four different districts through seven years from 1963 to 1969. The infection rate showed 2962 positive of 5974 heads (49.6%) of cattle at the Seoul first slaughter house in Seoul, 881 positive of 1021 heads (86.3%) in Cheju, and six(6) positive of 56 heads (11,1%) at Suwon, 58 positive of 306 heads(19.0%)at Joenju.
The infection rate 53.1%, (2907 positive heads of total 7357 heads exammed) is the representative infection rate at the cattle eurytremiasis in Korea, It showed little variation through a year and was increased as compared with those of the past period, from 1915 to 1945.
Fecal examinations in order to find out the local distribution of the pancreatic fluke were conducted on cattle, sheep, and goats raised in four districts, showing two(2) of 269 heads (0.7%) in Kyonggido, 41 of 212 heads (19.3%) in Cheju-do, and negative in both Chungnam-do and Joenbuk-do.
When an artificial infection was performed on rabbits and goats with metacercaria of the pancreatic fluke, Parenchyma of their pancreas were degenerated and the ducts were dilated, When cattle and sheep were infected naturally, the pancreatic ducts were also dilated, the wall was thickened, and adenomatous and epithelial hyperplasia was appeared. The conclusion, putting the foregoing pathological changes, has been arrived at chronic hyperplastic pancreatitis in the eurytremiasis of cattle, sheep, goats and rabbits.
