It emphasizes the incidence of cronic fasciolosis with different values, from 9.5% (in young) up to 16.6% (in adults), being in correlation to cattle grazing areas high dry land areas or low marshy areas, rich in aquatic gastropods, intermediate hosts in the life cycle of the parasite Fasciola hepatica. The hepatic and lung ehinococcosis have a different incidence with variation function of age category. Thus, in young the incidence, in both localizations (liver and lungs) have identic values from 28.5%; in adults values are different, 50% located in liver and 66.6% located in lungs. Keywords: incidence, ϔibrosis, parasitism, echinococcus, lymphonodule Introduction. The Control of parasitic diseases in animals has a chance only if a correct diagnosis, by specifying, is performed, and for obtaining it, it is necessary the exact knowledge of morphology and biology of the parasites species. The diagnosis of each disease is based on the clinical picture, but also mastery assignment of common laboratory procedures. For these reasons in the present paper we proposed a study on some techniques of morphological examination in the diagnosis of some severe endoparasitosis in cattle. Material and method. The research was performed during January - June 2014 in SC ROXMONT TRADING SRL slaughter house from IARA village, county of CLUJ. Organs were harvested immediately after the cattle slaughter-liver, lung and mesenteric lymphonodular masses- from 51 cattle (21 youth up to 3 years and 30 adults) of various breeds (Bălțata Românească, Hollstein crossbreeds and Pinzgau of Transylvania). For more accurate diagnosis there were used both methods of cutting multiple bodies and methods of kneading and passive sedimentary. Results and discussion. By necropsy investiga- tions carried out on a number of 51 liver masses, for fasciolosis diagnosis there were obtained the following values (Tab. 1). From the data obtained and presented in the table below it shows that the incidence of fasciolosis in cattle has different values depending on age. Thus, out of the 21 liver masses derived from cattle youth slaughtered, just 2 samples were positive, (9.5%), and of the 30 liver masses derived from adult male a number of 5 samples were positive (16.6 %). Overall, from the 51 liver masses examined 7 samples were positive highlighting the incidence of fasciolosis.
