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:
Bovine tuberculosis (BTB) is a dangerous zoonosis which presents a serious problem for endangered species such as European bison (Bison bonasus). Little is known about the influence of parasitic co-infections on the course and diagnosis of tuberculosis in animals. The best known co-infection in cattle is Fasciola hepatica and Mycobacterium bovis. The aim of this study was to review the most recent literature regarding tuberculosis and parasite co-infection in ungulates and relate the results to European bison. Our findings indicate that any comprehensive diagnosis of BTB should include parasitological monitoring, and the possible impact of such invasions on cellular response-based tuberculosis tests should be taken into account. The diagnosis of BTB is complex, as is its pathogenesis, and parasitic infestations can have a significant impact on both. This should be taken into account during further research and monitoring of tuberculosis in European bison.

Opis:
Changes in blood leucocyte levels were investigated in Spraque-Dowley rats vaccinated with cDNA or protein of glutathione S-transferase (GST) of F. hepatica and subsequently challenged with metacercariae of the liver fluke. The analysis of the leucocyte responses measured in vaccinated rats suggests that the form of antigen used for vaccination intluenced dynamics of white blood cell response to the fluke infection. The most clear differences were observed in neutrophil and eosinophil levels. The weakest reaction of these cells to the challenge infection was observed in rats vaccinated twice with cDNA. In contrast, in rats which received the first antigen dose as cDNA and the second vaccination with GST protein, both neutrophil and eosinophil responses were much higher, especially at 5 and 9 WAI.
Badano reakcję leukocytów krwi szczurów Spraque-Dowley immunizowanych cDNA lub białkiem transferazy S-glutationowej (GST) F. hepatica na inwazję metacerkarii tej przywry. Zwierzęta grupy 3 otrzymały pierwszą dawkę antygenu w formie cDNA a drugą w postaci białka. Próbki krwi do badań pobrano w dniu zarażenia a następne w 1, 5 i 9 tygodniu po zarażeniu (tpz). U szczurów szczepionych cDNA zaobserwowano statystycznie istotne obniżenie liczby limfocytów poczynając od 1 tpz. Największe różnice zaobserwowano w reakcji granulocytów. Szczury immunizowane dwukrotnie cDNA wykazywały najmniejszą eozynofilię zaś u szczurów grupy 3, wystąpiła w 9 tpz eozynofilia i neutrofilia silniej wyrażona niż u szczurów nie immunizowanych.

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.
