“…However, copper, selenium and zinc were rated normal, iodine elevated and manganese lowered when compared to cattle values. In a recent study, numerous trace elements have been assessed in livers of 30 captive and free-living European bison [ 41 ]. Interestingly, deficiency of Mn was also present in 20% of captive and 37% of free-ranging animals.…”

A newly-discovered foot disease of unknown origin in captive European Bison (Bison bonasus) was recently detected at Berne Animal Park. Dermatitis of the interdigital cleft of varying degrees of severity was diagnosed in all animals (n = 10). The aim of this study was to describe the gross and histological lesions of the interdigital cleft found in 10 captive European bison and to identify involved potential pathogens in affected feet using molecular-based methods for Treponema spp., Dichelobacter nodosus and Fusobacterium necrophorum. Lesions were scored according to the degree of gross pathology at limb level. In a single animal, the gross lesions were restricted to focal lesions on the dorsal aspect of the digital skin of each foot (score 1), whereas all other animals showed at least one foot with extended lesions including the interdigital cleft (score 2). The presence of viable spirochaetes was observed in all animals using dark field microscopy. Applying fluorescence in situ hybridisation (FISH) on biopsies, Treponema spp. were identified, infiltrating the skin lesions in varying numbers in nine animals. Nested PCRs for Treponema medium, Treponema phagedenis and Treponema pedis of swab samples showed three positive animals out of ten for the latter two, whereas pooled biopsy samples were positive in all ten animals for at least T. phagedenis (9/10) and/or T. pedis (7/10), while all samples were negative for T. medium. However, none of these Treponema species could be isolated and sequence analysis of the amplified products showed 100% match of 365 base pairs (bp) to Treponema phylotype PT3 and almost full match (530 of 532 bp, 99.6%) to Treponema phylotype PT13. The presence of T. phagedenis, PT3 and PT13 phylotypes was confirmed by FISH analyses. The phylotypes of T. phagedenis were present in all hybridized positive biopsies of Treponema spp., and PT13 and PT3 were less abundant. Neither D. nodosus nor F. necrophorum were detected. The histological Treponema score was mostly mild. Digital dermatitis in captive European Bison is contagious and differs from bovine digital dermatitis, concerning associated pathogens as well as gross appearance.

“…Bioindication provides information about the direct reaction of organisms, communities or ecosystems to natural or anthropogenic changes (Durkalec et al, 2018), since the biota reacts even to minor changes in external conditions and can even predict the geographical origin (Denisova et al, 2008;Franke et al, 2005;Gauthier-Lafaye et al, 2008;Huang et al, 2017;Ilyinskikh et al, 1998;Sheppard, 2011). The concentration of metals in the body of animals and human beings depends, not only on anthropogenic activity (Durkalec et al, 2018), but also on type of diet (Wang et al, 2014;Zhao et al, 2016), physiological specification of organs and tissues (Carpenè et al, 2017), and genetic characteristics of organism (Demirezen and Uruç, 2006). Bioindication includes a system for monitoring the state of the environment, assessing and forecasting changes in the medias (soil, water, air, biota) under the influence of natural and anthropogenic factors ("EcoLife", 2018).…”

“…Briefly, homogenized liver samples were mineralized in a mixture of 3 mL concentrated nitric acid HNO 3 (69%, Normatom, VWR, Leuven, Belgium) and 0.5 mL of 30% non-stabilized hydrogen peroxide solution (Suprapur, Merck, Darmstadt, Germany) using a Speedwave 4 microwave digestion system equipped with DAC-100 vessels (Berghof, Einingen, Germany). The analysis of the total element content was performed by ICP-MS (7700x, Agilent, Tokyo, Japan) as described previously (Durkalec et al 2018 ). The reliability of the obtained results was verified by analyzing the DORM-4 fish protein certified reference material (NRC, Ontario, Canada) (Supplementary Table S1 ).…”

The golden eagle (Aquila chrysaetos) and the white-tailed eagle (Haliaeetus albicilla), being apex predators and facultative scavengers, can bioaccumulate different environmental contaminants, including toxic elements that may adversely affect their health. We analyzed the levels of cadmium (Cd), lead (Pb), and other metals and metalloids, including arsenic (As), barium (Ba), beryllium (Be), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), thorium (Th), thallium (Tl), uranium (U), vanadium (V), and zinc (Zn) in liver samples taken from three golden eagles and 36 white-tailed eagles that were found dead across Poland to verify their exposure. We also used a systematic review to summarize the available literature data on Cd, Pb, and other studied elements in the liver of both eagle species. Analyses of trace elements in the liver samples of the Polish eagles revealed interspecific differences in Cd, Cu, and Mn and differences in Co, Mn, Tl, and Zn among study regions. All elements tested except Pb were below the suggested thresholds linked with adverse health effects in birds. The hepatic Pb found in almost half of all the tested individuals suggests environmental exposure to this toxic element. One of the tested white-tailed eagles had hepatic Pb above the threshold of sublethal poisoning. Although our results seem optimistic, as previous Polish studies showed a higher prevalence of birds with hepatic Pb exceeding the toxicity threshold, they indicate that exposure to this toxic metal could still pose an additional threat to the health of Polish eagles.
