BACKGROUND Growth-modulating noncytotoxic activity of 8-chloro-adenosine 3',5'-cyclic monophosphate (8-Cl-cAMP) showed inhibitory effect on growth of a wide variety of cancer cell lines in vitro and in vivo. To assess possible genotoxic effects of 8-Cl-cAMP, we conducted a study in vivo using male BALB/c mice. METHODS Clastogenic effects were estimated by(More)
Only two mitochondrial haplotypes (Korea and Japan) of Varroa destructor, the ectoparasitic honey bee mite, are known to be capable of infesting and successfully reproducing in Apis mellifera colonies worldwide. Varroa destructor (then called Varroa jacobsoni) was observed in Serbia for the first time in 1976. In order to obtain insight into the genetic(More)
In this work, Apis mellifera carnica and A. m. macedonica honey bees from Serbia, Bosnia and Herzegovina and Republic of Macedonia were analysed using molecular techniques in order to improve our knowledge about biogeography of A. mellifera on the Balkan peninsula. This is the first time that the indigenous honey bees from Bosnia and Herzegovina and(More)
The incidence, symptoms and consequences of Nosema ceranae infection were monitored in 200 honey bee colonies in Serbia over 5 years (2008–2012) to reveal if they display characteristics described for nosemosis type C. Continual high frequency of N. ceranae-positive colonies was recorded within each study year, ranging from 73 to 98 %. A seasonal pattern in(More)
Water pollution is known to play an important role in the pathogenesis of plastron, carapace and skin diseases of turtles. In this study, a total of 150 European pond turtles (Emys orbicularis) of different age and both sexes, originating from natural habitats in Serbia, were examined for morphological changes of the skin, plastron, carapace and skeletal(More)
Apitol, with cymiazole hydrochloride as the active ingredient, is used in bee-keeping against the ectoparasitic mite Varroa destructor. The preparation was evaluated for genotoxicity in cultured human peripheral blood lymphocytes. Sister chromatid exchange, the mitotic index and the cell proliferation index were determined for three experimental(More)
Catechol groups can be involved in redox cycling accompanied by generation of reactive oxygen species (ROS) which may lead to oxidative damage of cellular macromolecules including DNA. The objective of this investigation was to evaluate possible genotoxic effects of a natural catecholamine adrenaline in cultured human lymphocytes using cytogenetic (sister(More)
Equine piroplasmosis is significant tick-borne disease with wide distribution. The prevalence of equine piroplasmosis in Serbia, Montenegro and Bosnia and Herzegovina is unknown. In aim to obtain a first insight into the prevalence we performed molecular epidemiological study which included 142 horses, on seven locations in these three countries. We first(More)
