the aim of this study was to determine the seroprevalence of toxoplasma gondii in mares and stallionsin the province of ankara. sera from 168 clinically healthy horses were tested for the presence oftoxoplasma gondii antibodies using the sabin feldman dye test. toxoplasma gondii infection wasdetermined in 62 (36.9%) of 168 horses with the titers ranging from 1:16 to 1:256.

BACKGROUND Alkaline amylase has significant potential for applications in the textile, paper and detergent industries, however, low yield of which cannot meet the requirement of industrial application. In this work, a novel ARTP mutagenesis-screening method and fermentation optimization strategies were used to significantly improve the expression level of recombinant alkaline amylase in B. subt...

The tar genes directing the synthesis of poly(ribitol phosphate), the main teichoic acid in Bacillus subtilis strain W23, were sequenced. They are organized in two divergently transcribed operons, tarABIJKL and tarDF, as are the tag genes specifying poly(glycerol phosphate) synthesis in B. subtilis 168. The features of the tar genes as well as the putative participation of their products in the...

This study was carried out with a recently developed model of focal cerebral ischemia in the rat based on the photochemical induction of thrombotic stroke using the dye Rose Bengal. We examined the change in the volume of the lesion and brain water content, in separate groups of rats, at different times (1, 4, 24, 72, and 168 h) after the induction of the ischemic lesion. The volume of ischemic...
