A broad analysis of organisms is possible using molecular DNA as a marker. Mitochondrial genome and genes present in mtDNA, e.g. cytochrome b gene, are widely used in investigations and the significance of this research is becoming increasing. This gene is coded by heavy (H) strand of mtDNA. Cytochrome b is one of 11 subunits composed of bc1 complex of respiratory chain of mitochondria, the sequence of which is written down in the mitochondrial genome. Cytochrome b gene traits are a slow rate of variations during evolution, the presence of some parts of the gene that are more conserved and those which show high divergence rates. Those traits make the cytochrome b gene useful as a marker in many analyses. The cytochrome b gene is used as a tool in such studies as: legal and veterinary medicine, palaeontology, as well as phylogenetics, and it can attain the status of a universal metric.

The article reviews the main milk fat globule membrane (MFGM) protein, butyrophilin. Butyrophilin is an acidic, transmembrane glycoprotein which reveals the general receptor structure. Its unique location within the cell, the domain structure of the protein and site-specific expression occurring only during lactation indicate that butyrophilin protein is of great importance in milk lipid secretion process.

The aim of the work is to confirm the species differentiation of the nematodes of the Amidostomatidae family: Amidostomoides acutum (Lundahl, 1848) Lomakin, 1991; Amidostomoides monodon (Linstow, 1882) Lomakin, 1991, and Amidostomoides petrovi (Shakhtahtinskaya, 1956) Lomakin, 1991, which still are used in the parasitological literature as synonyms of Amidostomum acutum (Lundahl, 1848). The research material consisted of nematodes isolated from gizzards of dabbling ducks from the north-west of Poland. To confirm the species differentiation, DNA from the nematodes was isolated and approximately 630bp of the 28S rRNA gene were sequenced. The obtained DNA sequences were tabulated and then phylogenetic analysis were conducted using the UPGMA method. The results of the research distinctly diversify the nematodes of the genus Amidostomoides at the DNA level, which together with morphological and ecological differences among them (hosts from different systematic groups) enables to classify them into the separate species.
