Whirling Disease Caused by Metacercaria of a Fluke

Gastrodiscoidiasis, a plant-borne zoonotic disease caused by the intestinal amphistome fluke Gastrodiscoides hominis (Trematoda: Gastrodiscidae)

Gastrodiscoidiasis is an intestinal trematodiasis caused by the only common amphistome of man Gastrodiscoides hominis and transmitted by small freshwater snails of the species Helicorbis coenosus, belonging to the family Planorbidae. Human and animal contamination can take place when swallowing encysted metacercariae, by ingestion of vegetation (aquatic plants) or animal products, such as raw o...

Application of Pineapple Juice in the Fish Digestion Process for Carcinogenic Liver Fluke Metacercaria Collection

Pepsin is common digestive enzyme used for fish digestion in the laboratory to collect trematode metacercariae. In a field study, to survey the infected fish is needed a huge yield of pepsin and it is very expensive. Therefore, our purpose of this study was to investigate the candidate enzyme from pineapple juice which has a digestive enzyme called bromelain, a mixture of proteolytic enzymes, t...

Bifurcation and Hunting Phenomena of Rotating Speed in a Flexible Rotor System Caused by Whirling Motion

This paper presents the discussion of experimental results and numerical simulation of nonlinear phenomena in a flexible rotor system under mechanical resonance. The whirling motion of the first flexural mode of the rotor causes the hunting of its rotating speed. Hysteretic jump phenomena exist between the charge and the discharge of the rotation. It is shown that the quasi-periodicity of the w...
