Phase I biotransformation of albendazole in lancet fluke (Dicrocoelium dendriticum).
Dicroceliosis, a lancet fluke infection, is a frequent parasitosis of small ruminants and the anthelmintic drug albendazole (ABZ) is effective in control of this parasitosis. The aim of our project… Expand

Detection of Lawsonia intracellularis in wild boar and fallow deer bred in one game enclosure in the Czech Republic.
The prevalence of Lawsonia intracellularis between wild boar (Sus scrofa) and fallow deer (Dama dama) bred in one game reserve was investigated using the nested PCR method. In the study, 88… Expand

Biotransformation of albendazole and activities of selected detoxification enzymes in Haemonchus contortus strains susceptible and resistant to anthelmintics.
The increased activity of drug-metabolizing enzymes can protect helminths against the toxic effect of anthelmintics. The aim of this study was to compare the metabolism of the anthelmintic drug… Expand

The metabolism of flubendazole and the activities of selected biotransformation enzymes in Haemonchus contortus strains susceptible and resistant to anthelmintics.
Haemonchus contortus is one of the most pathogenic parasites of small ruminants (e.g. sheep and goat). The treatment of haemonchosis is complicated because of recurrent resistance of H. contortus to… Expand

Seroprevalence of Neospora caninum and Toxoplasma gondii in exotic ruminants and camelids in the Czech Republic
Neospora caninum and Toxoplasma gondii are the protozoan parasites with definitive hosts from order Carnivora. Due to vertical transmission, both parasites can cause abortions and neonatal mortality… Expand

Mycobacterium avium subsp. avium distribution studied in a naturally infected hen flock and in the environment by culture, serotyping and IS901 RFLP methods.
Mycobacterium avium subsp. avium (MAA) of serotype 2 and genotype IS901+ and IS1245+ was cultured from 21 naturally infected hens (Gallus domesticus) from one smallholder aviary. From a total of 330… Expand
