We report an outbreak of botulism that occurred in July 2002 in a group of 12 Alaskan Yu'pik Eskimos who ate blubber and skin from a beached beluga whale. Botulism death rates among Alaska Natives have declined in the last 20 years, yet incidence has increased.

We recorded EEG from both hemispheres and documented the state of the two eyes in two species of Cetaceans (one beluga and one bottlenose dolphin) and one species of Pinnipeds (two northern fur seals). In the dolphin and beluga we found that episodes of unihemispheric slow wave sleep (USWS) were associated with asymmetry in eye state. During USWS and asymmetrical SWS the eye contralateral to th...

Increased pressure, associated with diving, can alter cell function through several mechanisms and has been shown to impact immune functions performed by peripheral blood mononuclear cells (PBMC) in humans. While marine mammals possess specific adaptations which protect them from dive related injury, it is unknown how their immune system is adapted to the challenges associated with diving. The ...

background: probiotics, in form of microbial supplements, are known to be a suitable alternative for antibiotics and can affect the health indicators of host. objectives: the present study was conducted to assess the combined effects of dietary autochthonous saccharomyces cerevisiae and aspergillus niger on haematological and serumbiochemicalparameters of beluga sturgeon (huso huso) juveniles. ...

Objective: The purpose of present study was to obtain a complete understanding about anatomical features and echocardiography of Beluga (Huso huso) species in order to provide standard approaches for performing echocardiography on this sturgeon species.Design - Experimental studyAnimals -10 immature (2.5 years old) Beluga (Huso huso)Procedures- To perform echocardiography, Son...
