The “red disease” of eels (“Aalrotseuche” in German, Hireakab-yô" in Japanese) is an contagious disease originating from the infection o ?? causative bacteria, Pseudomonas punctata f. sacrowiensis SCHAPERCLAUS. The authors studied some pathological charac ?? ers in the blood of eels suffering from the red disease and the results obtained are as follows.
(1) The resistance of the erythrocytes against hypotonic saline solutions in diseased fish is stronger than that of normal healthy fish. (2) The precipitation velocity of blood cells was 2.6-5.5mm. (expressed in WESTERGREN's “middle value”) in affected fish and 2.5-2.6mm. in normal fish. (3) The blood viscosity showed the value ?? of 2.3-3.2 in the fo ?? mer and 3.4-3.6 in the latter.
The data of this experiment are summarized in tables 1 and 2.
