Etiological agents of scabies in domestic animals (dogs, cats, small mammals)
FILCOVÁ, Kristýna
The literature review, which constitutes the theoretical framework of the bachelor thesis, was based on the study of scientific literature. It contains a summary of causes of scabies in pets (dogs, cats and small mammals) and shows basic information about their morphology, localization within the host, clinical symptoms they produce, and about the methods of diagnostics, therapy and prevention used. The theoretical part also summarizes the most commonly used veterinary antiparasitics in the Czech Republic and their active substances against the causes of scabies. The practical part focused on collecting and processing data of pets infected by scabies in years 2016 - 2020. Attention was paid to the frequency of the infections, the species of pets infected by specific scabies causes and the most common veterinary antiparasitics used against specific scabies species in particular pets. The pet species with the most common disease was cat, which was most commonly infected with Otodectes cynotis (ear mite). The most commonly applied veterinary drug in cats infected with O. cynotis was veterinary preparation Stronghold.

Testing of the efficiency of selected antiparasitics on the metacercaria of the eye flukes (Diplostomum spathaceum) in grass carp (Ctenopharyngodon idella).
IPSEROVÁ, Jarmila
In this thesis, the efficiency of orally applied praziquantel (PQ) in two concentrations (Pramik 1 and Pramik 2) and mebendazole (MB) were tested on metacercaria of eye flukes (Diplostomum spathaceum, Rudolphi, 1819) in the grass carp (Ctenopharyngodon idella, Valenciennes, 1844). Naturally infected fish (average fish weight was 1.6 g and standard deviation was 0.1) were divided into four groups, for each tested group (Pramik 1, Pramik 2 and MB) belonged two aquariums of 100 liters each with 25 fish and for a control group belonged three aquariums of 100 liters each with 25 fish. The fish in the individual groups were fed with medicated feed containing praziquantel (Pramik 1 - 2.5 g PQ. kg-1 of feed, Pramik 2 - 1.25 g PQ. kg-1 of feed) and medicated feed mixture KP1 enriched with mebendazole (2.5 g MB. kg-1 of feed). The control group was fed with KP1 without drug addition. During the test the parasitological examinations of the ophthalmic lens were performed. The prevalence and intensity of infection were recorded. In the group of fish fed with medicated mixture containing MB, no statistically significant differences of the intensity of the infection indicating the MB potential in the fight against this fish infection were reported during the test. In the case of tested groups of fish fed with medicated feed mixture containing PQ (Pramik 1, Pramik 2), a statistically significant difference in the intensity of the infection was proved compared with the control group already after the first examination (estimated dose of consumed PQ. kg-1 of weight of fish = 500 and 250 mg). Near complete elimination of the eye flukes occurred in the group fed with feed mixture Pramik 1 after the expected consumption of 900 mg PQ. kg-1 of weight of fish. Statistically significant differences in the intensity of the infection in PQ treated fish groups compared to control groups indicate the usability of medicated feed containing PQ in the fight against fish diplostomosis.
