    Enterocytozon bieneusi
    Opis:
    Enterocytozoon bieneusi is the most commonly identified Microsporidia in humans and has also been detected worldwide in a large group of wild living and domestic animals. The identification of E. bieneusi in wildlife has raised the question of the importance of animal reservoirs in the epidemiology of microsporidiosis and the implications of the infection with this pathogen in hosts. This review summarizes the available molecular data on the variety of E. bieneusi genotypes, both potentially zoonotic and host-specific isolated from wild living mammals and birds. In contrast to microsporidial infections of humans and domestic animals, wildlife deserves attention as a source of significant environmental reservoir of E. bieneusi.

    Opis:
    The diagnosis of fungal infections remains a problem for the management of fungal diseases, particularly in the immunocompromised patients. Systemic Candida infections and invasive aspergillosis can be a serious problem for individuals who need intensive care. Traditional methods used for the identification and typing of medically important fungi, such as morphological and biochemical analysis, are time−consuming. For the diagnosis of mycoses caused by pathogenic fungi faster and more specific methods, especially after the dramatic increase in nosocomial invasive mycoses are needed. New diagnostic tools to detect circulating fungal antigens in biological fluids and PCR−based methods to detect species or genus−specific DNA or RNA have been developed. Antigen detection is limited to searching only one genus. Molecular genetic methods, especially PCR analysis, are becoming increasingly important as a part of diagnostics in the clinical mycology laboratory. Various modifications of the PCR method are used to detect DNA in clinical material, particularly multiple, nested and real−time PCR. Molecular methods may be used to detection of nucleic acids of fungi in clinical samples, to identify fungal cultures at the species level or to evaluate strain heterogeneity differences within the species. This article reviews some of the recent advances in the possibility of molecular diagnosis of fungal infections.

    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.
