The sequences of 10 conservative regions (CR) of minicircles of 6 selected isolates of freshwater fish try-panosomes have typical organization of this region with high degree of sequence conservation. The comparison with CRs of other trypanosomatids showed that freshwater fish trypanosomes represent a compact separate group within the genus Trypanosoma. The alignment of all sequences obtained revealed, however, the existence of 2 types of CRs in sequenced minicirclcs, with the differences concentrated in a short region. Taxonomic consequences of these results arc discussed.
The article on the Romani migration from Slovakia to the territory of the Czech Republic is based on the field research realized by the organization „Člověk v tísni" (People in Need) in
the year 2003. Analysis of this probe has shown that the non-asylum Romani migration was in the year 2003 much stronger than the migration of asylum seekers; that in the case of non-asylum migration this was in the first place an innovation migration, while in the case of
asylum seekers it was a so called survival migration. The non-asylum migration was usually a chain migration either of individuals or families and utilises family relations in the country of
origin as well as in the country of final destination. The information is being handed on not only through families, but also in settlements; some of them even specialize in some kind of
migration. The migration of Romani between the Czech Republic and Slovakia is bid-irectional, but more Romani migrate into the Czech Republic then to Slovakia, due to better economic situation there. Romani migration is a dynamic phenomenon and because of its character, based on close family relations of Romani residents on Czech and Slovak territory, it will for sure continue in future.
