Eggs as a Suitable Tool for Species Diagnosis of Causative Agents of Human Diphyllobothriosis (Cestoda)
 LEŠTINOVÁ, Kateřina
More than 2,000 eggs of 8 species of diphyllobothriid cestodes infecting humans were compared. Combination of morphometrical and ultrastructural (surface morphology) data made it possible to distinguish all species.

Morphological analysis of the tapeworms eggs of the order Diphyllobothriidea
 LEŠTINOVÁ, Kateřina
The order Diphyllobothriidea is a unique group of tapeworms in terms of the wide spectrum of definitive hosts involving all groups of tetrapods including man. They are almost globally distributed in both freshwater and marine ecosystems, but there are also terrestrial species. It is very difficult to identify species of diphyllobothriid cestodes to the species level. Morphology of the eggs might represent a new method in the differential diagnosis of these parasites. Besides the size and shape of the eggs, the structure of egg surface might play a significant role in the determination of different taxa. For the analysis of these characteristics Scanning Electron Microscopy (SEM) was used. Experimental infections in hamsters and man were done.

Characterization of a defensin of the tick \kur{Dermacentor marginatus}
 LEŠTINOVÁ, Kateřina
Antimicrobial peptides (AMPs), as a part of innate immune system of ticks and other living organisms, are able to eliminate pathogens. In ticks the most important group of AMPs is defensin family. In this work, defensin from the tick D. marginatus was studied. The defensin gene was isolated from D. marginatus fed females. Using RT-PCR the gene expression was detected in salivary glands and mitgut. Recombinant protein was expressed in the procaryotic expression system, purified and tested for its antimicrobial activity. Specific polyclonal rabbit antibodies (anti DR IgG) were prepared and tested for their specifity and sensitivity.
