Objective:To investigate the teziocrystalloscopic features of urine which were collected from both healthy rodents and those with parasitosis.Methods:Physical-chemical characteristics of urine samples that were collected from 15 mice and 20 rats were estimated by their ability to crystallize.Crystallization test results were interpreted with integrated identity table which includes 5 main classes of the crystalline and amorphous formations.Additional quantitative and semiquantitative evaluation indicators were also used.Results:Presence of Trichinella spiralis in animal organism transformed results of the biofluid free crystallogenesis.The main components of rats’ urine facia were single-crystalline rectangles which were made of cholesterol and its derivatives.The biofluid microsamples of healthy rats and rats with echinococcosis had both common and difference.Conclusions:Urine teziocrystalloscopic analysis is an informative method for diagnosis of helminthiasis in animals.
