Parasites of the digestive tract of sheep and goats from organic farms in Western Pomerania, Poland
PublikacjaThe aim of the study was to determine the prevalence and intensity of parasite infection of the digestive tract in sheep and goats from the West Pomerania region following anti-parasite treatment. Feces were freely collected from sheep and goats kept on organic farms and subjected to analysis by the Willis-Schlaf and McMaster’s flotation methods. The mean extensity of infection by gastrointestinal parasites...

Soil contamination with geohelminths in children’s play areas in Szczecin, Poland
PublikacjaThe presence of invasive forms of parasites in the soil represents a potential threat to public health, especially for children. The aim of the study was to determine the degree of contamination with geohelminth eggs of soil samples collected from sandpits and playgrounds in the Szczecin area. The findings showed overall prevalence of soil samples contaminated with geohelminth eggs in the soil and sand...

Real-Time PCR: molecular technique of many applications
PublikacjaReal-Time PCR is a sensitive DNA amplification technique initially applied in genetics and molecular biology. It enables in vivo copying of the selected DNA fragment (flanked by two primers) by the thermostable polymerase (in the presence of magnesium ions and deoxynucleotide triphosphates) and simultaneous measurement of the fluorescence. For one or more specific sequences in a DNA sample, real-time PCR enables both detection...

Induction of immune responses in sheep by vaccination with liposome-entrapped DNA complexes encoding Toxoplasma gondii MIC3 gene
PublikacjaToxoplasma gondii is a parasite that has been extensively studied due to its medical and veterinary importance in terminating pregnancies. Consequently, a satisfactory vaccine is required to control itsadverse effects on pregnant animals. The microneme protein, MIC3, is a major adhesion protein that binds to the surface of host cells and parasites, and is therefore a potential vaccine against T. gondii.The viability of MIC3 as...

Review on mechanisms and efficiency of removal of microbiological contaminants in constructed wetlands
PublikacjaConstructed wetlands (CW) have been considered as a waste and a stormwater treatment systems for small communities or for areas with unsteady sewage flow conditions. Several investigations were undertaken for estimation suspended solids, organic matter and nutrients efficiency removal but only few focused on retention of microorganisms in constructed wetlands. In this review mechanisms of elimination of viruses, indicator bacteria...

Phytoecdysteroid containing plants – a source of bioactive compounds with potential anticarcinogenic effects
PublikacjaEcdysteroids are a group of steroids synthesized in inver- tebrates as molting hormones and also in some plants as secondary metabolites acting as a defense against parasites. These compounds do not naturally occur in mammals and are not structurally related to mammalian steroid hor- mones, consequently do not activate mammalian hormone receptors. Ecdysteroids exhibit very low toxicity to mam- mals and to date no serious side effects...

Detection of Toxoplasma gondii oocysts in environmental samples
PublikacjaToxoplasma gondii is an obligate intracellular parasite that has capacity to infect warm-blooded animals. Human toxoplasmosis is usually asymptomatic, whereas severe complications may occur in immunocompromised patients (e.g. AIDS) or in case of congenitalinfection. One of the sources of acquiring human toxoplasmosis is ingestion of T. gondii oocysts. It is known that newly infected cats can shed millions of oocysts into the environment,...
