The Eurasian otter () is a semi-aquatic mammal classified as near-threatened by the International Union for Conservation of Nature. There have been few reports on their diseases, especially neoplasms. Here we describe exocrine nodular hyperplasia and adenomas in the pancreas, along with suppurative pleuropneumonia and urolithiasis, in an aged captive Eurasian otter. Pancreatic adenomas are rare in animals, and coexistence of adenoma and nodular hyperplasia in the pancreas has not been reported previously in veterinary medicine, to our knowledge.

Leishmania infantum causes disease endemic in the Mediterranean Basin that affects humans and various mammals, including mustelids. Clinical leishmaniosis has been documented in domestic ferrets (Mustela putorius furo) and in a captive Eurasian otter (Lutra lutra). The European mink (Mustela lutreola), one of the world's most endangered mammals, is experiencing severe population declines linked to habitat degradation, climate change, the introduction of non-native species, and diseases.

HPAI A(H5N1) virus detections were predominant and mainly located in western, central and south-eastern Europe. Most detections in wild birds concerned waterfowl, particularly swans and geese, but also gulls were involved.

The aim of this study was to evaluate the concentrations of elements and heavy metals (Hg, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Cu, Zn, Se, Rb, Sr, Zr, Mo, Sb, Ba, and Pb) in fecal samples of the river otter (Lutra lutra) which inhabits the Javorinka mountain stream in the High Tatras, part of the Western Carpathians in Slovakia. Javorinka serves as a model stream with minimal human impact. As a predator, the otter is a suitable bioindicator of the environment it inhabits.

Candidatus Midichloria mitochondrii (Ca. M. mitochondrii), an endosymbiont intracellular bacterium living in the mitochondria of several tick species, especially ixodid species, has been proposed as a potential marker for monitoring tick-bite exposure.

Approximating the stiffness of biological materials can give important insights into how structures deform and when they may fail. Some samples may be too precious to test to destruction, or too fine to position accurately for conventional material testing, which makes it challenging to obtain approximations of material stiffness. Using two-dimensional scans, non-destructive bending tests, and finite element (FE) modeling, we show that we can approximate the modulus of elasticity of samples by fitting FE model data to that of experimental bend tests.
