Rabies: decimation of a wolf pack in artic Alaska.

In a pack of ten wolves, one wolf behaved atypically and fought with several packmates. This wolf was shot when it approached the author. Within 4 weeks at least six other members of the pack were dead. Rabies was confirmed in the wolf that was shot and in two others that had not decomposed. Most of the wolves infected with rabies had sought or remained at familiar areas in the core area of their territory, which implies that they were not contacting neighboring packs. This was confirmed with an aerial survey. Arctic foxes, experiencing a regionwide rabies epizootic, were suspected vectors.

Characterization of bacterial communities associated with deep-sea corals on Gulf of Alaska seamounts.

Although microbes associated with shallow-water corals have been reported, deepwater coral microbes are poorly characterized. A cultivation-independent analysis of Alaskan seamount octocoral microflora showed that Proteobacteria (classes Alphaproteobacteria and Gammaproteobacteria), Firmicutes, Bacteroidetes, and Acidobacteria dominate and vary in abundance. More sampling is needed to understand the basis and significance of this variation.

Serological evidence of morbillivirus infection in polar bears (Ursus maritimus) from Alaska and Russia.

One-hundred-and-ninety-one samples of blood serum collected from 186 polar bears (Ursus maritimus) between 1987 and 1992 were analysed for morbillivirus antibodies. The samples were collected in the Bering, Chukchi and East Siberian seas. Sixty-eight samples (35.6 per cent) had morbillivirus antibody titres > 5; the percentage of positive samples ranged from 26.2 to 46.2 per cent from year to year. The proportions of adults, sub-adults and cubs which were seropositive were 43.9, 35.7 and 37.9 per cent respectively. Some seropositive dams had seronegative young and some that were seronegative had seropositive young. One litter of two cubs, in which the dam was seronegative, had one seropositive and one seronegative cub. Seropositive bears occurred in all the areas from which the samples were collected but there was a significantly greater incidence in the bears sampled in Russia. The high prevalence of seropositive bears over the period suggests that the bear morbillivirus is endemic in these regions of the Arctic, but its source is unknown.
