OBJECTIVES Pharmaceuticals and heavy metals such as diclofenac and lead, respectively, have been identified as environmental contaminants toxic to birds and posing serious threats to declining populations of raptors worldwide. The aim of the present study was to test the hypothesis that a sublethal combination of non-steroidal anti-inflammatory drugs and(More)
OBJECTIVES The aim of the present study was to evaluate differences between juvenile and adult Japanese quails in responses to the exposure to cyanobacterial biomass in the diet. DESIGN The OECD 205 Guideline on Avian Dietary Toxicity Test (1984) was employed in the experiment. A total of 75 freshly hatched chicks and 30 adults were exposed to(More)
BACKGROUND The aim of the present study was to investigate biochemical and oxidative stress responses to experimental F. tularensis infection in European brown hares, an important source of human tularemia infections. METHODS For these purposes we compared the development of an array of biochemical parameters measured in blood plasma using standard(More)
OBJECTIVES HI-6 is an antidotum suitable for treatment of intoxication by nerve agents. The recent investigation appointed its modulation of inflammatory response as well as vegetative nervous system activity. However, the present experiments were carried out in order to assess the antioxidant effect of HI-6 in irradiated animals. METHODS male Wistar rats(More)
OBJECTIVES The present study was aimed at evaluation of the response of Japanese quails to cyanobacterial biomass administered in feed using biochemical profiles and parameters of reproduction. DESIGN Effects of cyanobacterial biomass were studied according to the OECD 206 Guideline on Avian Reproduction Toxicity. A total of 16 control and 16 experimental(More)
OBJECTIVES The objective of this study was to examine the hypothesis that a combination of cyanobacterial biomass containing microcystins, acetylcholinesterase inhibitor and anticoagulant can enhance avian toxic effects produced by single exposures only. METHODS A total of 48 two-month-old Japanese quails (Coturnix coturnix japonica) with average body(More)
OBJECTIVES Previous studies using oral administration of environmentally relevant doses of cyanobacterial biomass containing microcystins (MCs) induced only sub-lethal effects in experimental birds. Therefore, the objective of this study was to obtain data on avian high-dose toxicity of MCs and compute LD50, if possible, following the natural oral route of(More)
OBJECTIVES The causative agent of tularemia Francisella tularensis is highly infectious and lagomorphs are important reservoirs and a source of human disease. The aim of the present study was to test the hypothesis that sublethal exposure to pesticides increases the susceptibility of hares to F. tularensis and modulates the course of the infection. (More)
