Opis:: Motylica wątrobowa (Fasciola hepatica) to jedna z przywr digenicznych (Digenea), która dzięki wykształceniu w trakcie ewolucji układu pasożyt-żywiciel szeregu przystosowań, zwłaszcza biologicznych, osiągnęła ogromny sukces ewolucyjny. Pomimo wielu przeszkód ograniczających jej rozwój, wywoływana przez motylicę fascjoloza stanowi ciągle istotny problem gospodarczy. Jedną z przyczyn trudności w zwalczaniu motylicy wątrobowej jest ogromna płodność pasożyta oraz występowanie tzw. "lat motyliczych", które stwarzają korzystne warunki do licznego namnażania się żywicieli pośrednich - błotniarek moczarowych Galba truncatula. Znając biologię pasożyta można przeciwdziałać inwazji F. hepatica u zwierząt hodowlanych, nie dopuszczając do zamknięcia cyklu rozwojowego poprzez niszczenie żywicieli pośrednich (melioracje i osuszanie pastwisk).
Liver fluke (Fasciola hepatica) is one of the Digenea that due to a number of adaptations developed during the parasite-host relationship achieved an enormous evolutionary success. Despite impediments associated with completing the indirect life cycle, triggered by the liver fluke fasciolosis constitutes the relevant economic problem. One of the reason for the difficulties in combating the liver fluke is its huge fertility and appearing of so-called "fluke years", which create favorable conditions to numerous multiplying of the alternat hosts (Galba truncatula). Knowing the biology of F. hepatica it is possible to counteract invasion of the parasite, by preventing termination of its life cycle through destroying the intermediate hosts (land reclamation and draining the pastures).

Opis:: Pathological changes of liver in infection of Fasciola hepatica. Fasciolosis caused by Fasciola hepatica is a hepatic parasitic infection that affects numerous mammal species, mainly ruminants, in several countries of Europe, Asia and America. The economic significance of fasciolosis is mainly due to direct losses caused by a decrease of weight rate, milking capacity and the confiscation of altered livers in slaughterhouse. In this review we present mechanisms of damaging of host liver during invasion of Fasciola hepatica. Parasites digest hepatic tissue and cause extensive parenchymal destruction with intensive haemorrhagic lesions and immunological reactions. Mechanical liver damage is due to migrating juvenile fluke. Macerated hepatic cells have been observed inside the oral sucker and pharynx. Moreover, the process of ulceration of liver tissue was observed in regions adjacent to the spiny body of fluke tegument. On the other hand, the injury of the liver can be induced chemically by factors produced or induced by the fluke. Probably, fluke proteases and other tissue-degrading enzymes can be responsible for negative effect on liver parenchyma. There is no evidence to link fluke-enzymes with tissue penetration. The consequences of liver damage resulting from the migrating flukes compromises liver function which is reflected in changes of plasma protein concentration (albumin, globulin). Additianally, changes of levels of hepatic enzymes released into the blood as a result of damage of liver tissue are used to monitor the progress of the infection in a variety of Fasciola hepatica hosts and as a sensitive diagnostic aid in field infection.

Opis:: Ultrastructure of the digestive gland has been studied in G. truncatula, uninfected and infected with F. hepatica larvae. The digestive gland of G. truncatula consist of seccretory-resorption cells and calcareous cells. On the 20 day post infection the damage to the secretory cells were small and did not inhibit their activity. On the 60 day post infection the gland structure was totally altered: reduced height of secretory cells, lack of Golgi apparatus, myelin-like degradation of mitochondria, reduction and desintegrating of rough endoplasmic reticulum. These damage of secretory and calcareous cell to bring about a total inhibition of their secretory activities.

Opis:: The influence of Fasciola hepatica invasion on the assorted milk quality parameten in cows. The investigations of the influence of Fasciola hepatica invasion on the assorted parameters of milk quality were performed in cows. Mean protein content in the milk from infected animals ammounted 3.60% and was higher than in the milk from uninfected cows (3.30%). Similar tendency was observed in the case of the fat (5.08% and 3.91 %) and lactose (4.36% and 4.34%). The count of somatic cells in milk from infected cows was lower than in milk from uninfected animals (356.07 and 1776.92). It can indicate immunosupressive activity of Fasciola hepatica on the host.

Opis:: Fasciolosis, caused by the liver fluke (Fasciola hepatica) is an important issue for both human and animal health. The disease evokes economic losses which are a consequence of impaired animal productivity leading to higher costs of meat and milk production, as well as liver condemnation. The goals of this thesis were to: (1) elaborate a molecular method - PCR for the detection of F. hepatica DNA in intermediate and definite hosts; (2) estimate the usefulness of a recombinated cysteine proteinase produced in E. coli in the form of inclusive bodies in serological diagnosis of F. hepatica infection in definite hosts, using an enzyme-linked immunosorbent assay (ELISA); (3) conduct field research on the prevalence of infection among intermediate and definitive hosts (cattle) in chosen regions of Poland, utilizing the elaborated methods. Based on the results obtained in this study, it was established that it is possible to detect F. hepatica DNA in the feces of definite hosts with the elaborated PCR method. The amplification of a 124 base pair tandem repeat allows the detection of fluke larval stages in intermediate hosts within 12 hours of exposure and F. hepatica infection in definite hosts (by the 5th week in rats, 8th week in sheep and 10th week in cattle). Therefore, the PCR test is more sensitive than traditional microscopic methods. Furthermore, it was determined that, the recombinated cysteine proteinase in the form of inclusive bodies, after solubillization exhibits antigenic properties of the native protein and the ELISA method based on this antigen may be useful as a tool for diagnosing fasciolosis in sheep and cattle, in both serum and milk samples. The test achieves a greater sensitivity and specificity than an ELISA based on native excretory-secretory antigens. The results of field research indicate that Fasciola hepatica is a frequent parasite of cattle in central and eastern Poland. The mean prevalence was 34.86% (±16.95) in all studied areas. The prevalence among intermediate hosts varied greatly (0–100%). The elaborated tests were proved to be valuable, mutually complementing diagnostic tools, applicable to different epidemiological situations.

Aim of the work was to determine extensitivity of appearance of hepatica among catlle pul to slaughter in slaughtershouses in Lublin's voivodship from 1993 to 2001. Substance for the work was braught from the annual reports of official examination of slaughtered animals, reached from both main Inspectorate (department) of Veterinary in the Ministry of Agriculture and from Regional Institute of Veterinar's Hygiene in Lublin. Results of researches are as follow: extensivity of infection of Fasciola hepatica among cattle in Lublin and voivodship between 1993-1999 oscillates about 5%. In 2000 extensivity of invasion reached 10,9 %.

Opis:: The trematode F. hepatica is an internal parasite of many species of animals including men. In ruminants, fasciolosis is an economically important disease often resulting in a chronic and sub-clinical infection. The mechanisms of immune responses of final bosts to this infection are still poorly understood. Experimental and clinical studies reported so far suggest that both humoral and cellular effectors of the immune response are important to control the duration of F. Hepatica infection. However, there are considerable variation botb inter-species and between various strains of the same species in regulation of the response as weil as abilities to develop resistance to subsequent infections.
