Collections of 8805 individuals of chewing lice from wild and domestic fowl in the Central Ciscaucasia were processed. According to original and literary data, 102 species of Mallophaga are known from this territory; 15 of them were recorded for the first time. Most of all the chewing lice species known in the territory are parasites of passerine birds; the number of species associated with each of the 12 remaining bird orders of birds is several times smaller. An exchange of chewing lice between some species of hosts, including domestic and wild fowl, is possible. © 2011 Pleiades Publishing, Ltd. Source

The possibility of detecting antigens of plague, tularemia, and brucellosis microbes with magnetic latex (ML)-based test systems has been demonstrated. MLs were prepared from latexes (polyacroleine microspheres, 1.2-1.8 ± 0.1 μm) by exposing the particles to a 25-35%-solution of ferrous sulfate for 0.5 h and then to a 15-25%-aqueous solution of ammonia for 0.5 h in a 100°C water bath and dehydrating after each operation. The possibility of preparing magnetic latex immunosorbents (MLIS) by ligand immobilization on ML and using them in magnetic latex ELISA (ML-ELISA) for the detection of microbial antigens was demonstrated. The detection limit in ML-ELISA equaled 102-103 microbial cells in 1 ml (cells/ml). Relative experimental error was not higher than 8%. © 2010 Pleiades Publishing, Ltd. Source
