Výskyt a diverzita amphistomních motolic u skotu
VOGALOVÁ, Pavlína
The thesis deals with gastric woodlice of the family Paramphistomidae, which are common parasites of ruminants. Their immature stages can cause severe pathological changes in the host's digestive tract, and massive infection can lead to host death. Adult parasites cause infections of the rumen mucosa, resulting in lower production. The prevalence and diversity of these flukes is currently not systematically monitored. The aim of this study is to describe the occurrence and diversity of gastric flukes in cattle in the Czech Republic and Austria. The practical part consists of examination of dairy cattle faeces from different herds for the presence of eggs using standardised parasitological methods, optimization of a PCR method for direct detection of flukes from the faeces, genotyping of the flukes found, processing of the results using appropriate statistical methods, and comparison with published data.
Účinnost vybraných postupů konzervace ryb na zachování morfometrických ukazatelů
VOGALOVÁ, Pavlína
This bachelor's thesis is focused on the topic of fish fixation and preservation. Experiments regarding various preservation methods are covered in many scientific ichthyological texts. Unfortunately, most of these works are exploring only one preservation method, so mostly there isn't the possibility of comparison with different methods using the same species. Aim of this work is introduction to preservation and fixation methods, that affect morphometric parameters of fish. Theoretical part of this thesis are procedures of fixation and preservation. The experiment itself is focusing on effect of preservation over time. Selected morphometric parameters were observed and measured in selected fish species to discover potential changes in these parameters. Measurements were being taken every two weeks for few months.
