First data on parasites of the invasive brown bullhead (Siluriformes: Ictaluridae) in Ukraine.

This study describes the parasite community of non-native brown bullhead, (Actinopterygii: Ictaluridae), collected at three sites in the river Vistula Basin (Lake Svitiaz, Lake Pisochne, and Lake on Plastova) and one site in the river Diester Basin (Lake Stryiska), in Ukraine. Our data represent the first comprehensive study of parasite community in this fish species in Europe. Sixteen parasite taxa were found, including species co-introduced from North America and species acquired in the European range.

[Microbiological validation of the composition of "decaceol", an antiseptic prolonged-release drug].

With the aid of different microbiological methods, antimicrobal properties of decametoxine, a home-produced antiseptic, were studied together with those of the synthetic zoelite NaA-base drug preparation. The antimicrobial activity of the above drug has been shown to be of a synergistic character that makes it a very promising medical agent which will, we believe, come to be widely used in medical practice.
