Dolphin-WET-Development of a Welfare Evaluation Tool for Bottlenose Dolphins () under Human Care.

Ensuring high standards of animal welfare is not only an ethical duty for zoos and aquariums, but it is also essential to achieve their conservation, education, and research goals. While for some species, animal welfare assessment frameworks are already in place, little has been done for marine animals under human care. Responding to this demand, the welfare committee of the European Association for Aquatic Mammals (EAAM) set up a group of experts on welfare science, cetacean biology, and zoo animal medicine across Europe.

Injectable Anesthesia With Medetomidine, Ketamine, and Butorphanol in Captive Humboldt Penguins ().

The effects of an injectable anesthesia with 0.05 mg/kg medetomidine, 5 mg/kg ketamine, and 0.5 mg/kg butorphanol administered together intramuscularly were evaluated in 22 captive Humboldt penguins (, 10 male and 12 female), with a mean age of 8.

Bottlenose dolphin calves have multi-year elevations of plasma oxytocin compared to all other age classes.

Providing for infants nutritionally via lactation is one of the hallmarks of mammalian reproduction, and infants without motivated mothers providing for them are unlikely to survive. Mothers must maintain regular contact with infants both spatially and temporally while utilising their environment to forage, avoid threats and find shelter. However, mothers can only do this and maximise their reproductive success with some degree of co-operation from infants, despite their developing physical and cognitive capabilities.

Dolphin-derived NETosis results in rapid Toxoplasma gondii tachyzoite ensnarement and different phenotypes of NETs.

Toxoplasma gondii is a cosmopolitan zoonotic parasite and nowadays considered as an emerging neozoan pathogen in the marine environment. Cetacean innate immune reactions against T. gondii stages have not yet been investigated.

Atypical myopathy in Père David's deer (Elaphurus davidianus) associated with ingestion of hypoglycin A.

From 2004 until 2016, 21 Père David's deer (Elaphurus davidianus) have died for unknown reason at Zoo Duisburg. These deer, also known as milu, have succumbed from a myopathy that occurred seasonally in autumn and in spring. The clinical signs shown by the animals closely resembles those of a disease called equine atypical myopathy (EAM), which is formerly known in horses.

DETECTION OF MYCOBACTERIUM AVIUM SUBSPECIES PARATUBERCULOSIS IN ROCK HYRAXES ( PROCAVIA CAPENSIS) IMPORTED FROM SOUTH AFRICA.

Mycobacterium avium subspecies paratuberculosis (MAP) causes chronic, progressive, and consecutively fatal enteritis, especially in ruminants. MAP distribution among wildlife is not yet clear. In this study, three wild-born rock hyraxes ( Procavia capensis) had been imported from South Africa to a German zoological garden.

ORAL SQUAMOUS CELL CARCINOMA IN AN AGED CAPTIVE WHITE RHINOCEROS (CERATOTHERIUM SIMUM).

A 48-yr-old captive white rhinoceros ( Ceratotherium simum ) was euthanized due to old age, pododermatitis, and progressive laminitis of the middle toe of the left fore- and hindlimbs. Severe chronic necrotizing periodontitis and dental loss was diagnosed, although food intake prior to death had not decreased. In addition, extensive ulceration of the tongue was noted.

Aerial low-frequency hearing in captive and free-ranging harbour seals (Phoca vitulina) measured using auditory brainstem responses.

The hearing sensitivity of 18 free-ranging and 10 captive harbour seals (Phoca vitulina) to aerial sounds was measured in the presence of typical environmental noise through auditory brainstem response measurements. A focus was put on the comparative hearing sensitivity at low frequencies. Low- and mid-frequency thresholds appeared to be elevated in both captive and free-ranging seals, but this is likely due to masking effects and limitations of the methodology used.

Occurrence of Babesia species in captive reindeer (Rangifer tarandus) in Germany.

Two cases of acute babesiosis in captive reindeer (Rangifer tarandus) in two German zoos in 2009 and 2012 triggered this study to investigate the occurrence and species diversity of Babesia parasites infecting reindeer in different zoos and deer parks in Germany. Between June and December 2013, blood samples were taken from 123 clinically inapparent reindeer from 16 different facilities. Samples were tested for the presence of Babesia species DNA by conventional PCR and sequence analysis of part of the 18S rRNA gene.

The first case of intersexuality in an African dwarf crocodile (Osteolaemus tetraspis).

To the authors knowledge this is the first case of intersexuality in an African dwarf crocodile (Osteolaemus tetraspis). An adult African dwarf crocodile with a male-typical phenotype lived at Zoo Duisburg in Germany for 10 years. It died in October 2012 despite intensive treatment as a result of terminal septicemia.
