Studium prevalence \kur{Giardia intestinalis}
BROŽOVÁ, Kristýna
The present project is focused on the study of a prevalence of the gut protist, Giardia intestinalis, in human and animal samples using two diagnostic approaches: (i) coproscopical diagnostics, specifically Sheather flotation technique, and (ii) PCR. First, three PCR protocols for different genes (triosephosphate isomerase, beta-giardin and small ribosomal subunit) were optimized by gradient PCR. Based on these result, the gene TPI was chosen as the best option for molecular diagnostics of G. intestinalis in the collected stool and fecal samples. Giardia was detected only in the animal samples (2/41, dog and rabbit samples), all the analysed human samples remained negative. Further, the TPI protocol showed low sensitivity for diagnostics of G. intestinalis.
