    Wildlife population changes across eastern europe after the collapse of socialism

    When political regimes fall, economic conditions change and wildlife protection can be undermined. Eastern European countries experienced turmoil following the collapse of socialism in the early 1990s, raising the question of how wildlife was affected. We show that the aftermath of the collapse changed the population growth rates of various wildlife taxa. We analyzed populations of moose (Alces alces), wild boar (Sus scrofa), red deer (Cervus elaphus), roe deer (Capreolus capreolus), brown bear (Ursus arctos), Eurasian lynx (Lynx lynx), and gray wolf (Canis lupus) in nine countries. Population growth rates changed in 32 out of 49 time series. In the countries that reformed slowly, many species exhibited rapid population declines, and population growth rates changed in 83% of the time series. In contrast, in countries with fast post- socialism reforms, many populations increased rapidly, and growth rates changed in only 48% of time series. Our results suggest that the direction and frequency of the changes were associated with socioeconomic conditions, and that wildlife populations can be greatly affected by socioeconomic upheavals

    A European Concern? Genetic Structure and Expansion of Golden Jackals (Canis aureus) in Europe and the Caucasus

    In the first continent-wide study of the golden jackal (Canis aureus), we characterised its population genetic structure and attempted to identify the origin of European populations. This provided a unique insight into genetic characteristics of a native carnivore population with rapid large-scale expansion. We analysed 15 microsatellite markers and a 406 basepair fragment of the mitochondrial control region. Bayesian-based and principal components methods were applied to evaluate whether the geographical grouping of samples corresponded with genetic groups. Our analysis revealed low levels of genetic diversity, reflecting the unique history of the golden jackal among Europe’s native carnivores. The results suggest ongoing gene flow between south-eastern Europe and the Caucasus, with both contributing to the Baltic population, which appeared only recently. The population from the Peloponnese Peninsula in southern Greece forms a common genetic cluster with samples from south-eastern Europe (ΔK approach in STRUCTURE, Principal Components Analysis [PCA]), although the results based on BAPS and the estimated likelihood in STRUCTURE indicate that Peloponnesian jackals may represent a distinct population. Moreover, analyses of population structure also suggest either genetic distinctiveness of the island population from Samos near the coast of Asia Minor (BAPS, most STRUCTURE, PCA), or possibly its connection with the Caucasus population (one analysis in STRUCTURE). We speculate from our results that ancient Mediterranean jackal populations have persisted to the present day, and have merged with jackals colonising from Asia. These data also suggest that new populations of the golden jackal may be founded by long-distance dispersal, and thus should not be treated as an invasive alien species, i.e. an organism that is “non-native to an ecosystem, and which may cause economic or environmental harm or adversely affect human health”. These insights into the genetic structure and ancestry of Baltic jackals have important implications for management and conservation of jackals in Europe. The golden jackal is listed as an Annex V species in the EU Habitats Directive and as such, considering also the results presented here, should be legally protected in all EU member states

    Experimental Substantiation of the Possibility to Use Finite Cell Line CHO-K1 for Determination of Specific Activity of Components of Chemical Cholera Vaccine

    Objective was to experimentally substantiate the possibility to use the finite cell line CHO-K1 for measuring specific activity of cholera toxin and component of the vaccine choleragen-anatoxin in the process of chemical cholera vaccine manufacturing. Materials and methods. The studies involved the finite cell line CHO-K. The registration of results of bio-indication method was performed visually with the help of inverted microscope and photometrically - in colorimetric test for the assessment of metabolic activity of the cells at the wave length of 595 nm. Results and discussion. The proposed method allows for determining the toxin-production activity of Vibrio cholerae 569B strain during submerged cultivation in bioreactor and specific activity of choleragen-anatoxin by anatoxin binding measuring using cell cultures. The results correlate with the data obtained using intradermal Craig’s technique, GM1-ELISA and radial passive immune hemolysis (RPIH). Introduction of cell culture method into practice will provide for significant decrease in the volumes of usage of animals at the stages of manufacturing of chemical bivalent cholera vaccine

    Objective of the study was to select the standardized substrate containing dry hydrolysate of casein for preparation of nutrient medium utilized for manufacturing bivalent chemical cholera vaccine under submerged cultivation of cholera vibrio strains in fermenters. Materials and methods. We used Vibrio cholerae O1 strains of classical biovar: strain 569B Inaba and strain M-41 Ogawa. Examined were two dry substrates of the medium: enzymatic hydrolysate of casein, Type I Himedia (India) and pancreatic hydrolysate of casein, produced by the State Scientific Center of Applied Microbiology and Biotechnology (Russian Federation). Produced under laboratory conditions at the premises of the RusRAPI “Microbe” medium was used as a control. Submerged cultivation was conducted in bioreactors during (9±1) h with aeration and automatic feeding of glucose and ammonia. Production of protective antigens was measured applying immunochemical and biological methods. Results and discussion. It is demonstrated that submerged cultivation of cholera vibrio production strains on nutrient media under study provides for synthesis of protective antigens the parameters of which comply with the requirements of normative documentation. More standardized and higher indicator values of the target product are ensured by cultivation of producer strains on nutrient medium with a substrate from dry enzymatic hydrolysate of casein, containing (1.5±0.1) g/l of amino nitrogen for the strain V. cholerae M-41 and (2±0.1) g/l – for V. cholerae 569 B. Transition to the use of standardized dry protein components of cultivation media does not lower the quality of the chemical cholera vaccine, but allows for the reduction of cost price and duration of technological process
