| neospora caninum and toxoplasma gondii antibody prevalence in alaska wildlife. | free-ranging caribou and moose populations in some regions of alaska undergo periodic declines in numbers. caribou and moose are managed by the state as valuable resources for not only sustenance and subsistence, but also for cultural heritage. incidence and prevalence of diseases that may impact herd health and recruitment from year to year are relevant to management decisions aimed to protect the long-term viability of these herds. neospora caninum and toxoplasma gondii are two apicomplexan pa ... | 2010 | 20688628 |
| a conceptual model for the impact of climate change on fox rabies in alaska, 1980-2010. | the direct and interactive effects of climate change on host species and infectious disease dynamics are likely to initially manifest\ at latitudinal extremes. as such, alaska represents a region in the united states for introspection on climate change and disease. rabies is enzootic among arctic foxes (vulpes lagopus) throughout the northern polar region. in alaska, arctic and red foxes (vulpes vulpes) are reservoirs for rabies, with most domestic animal and wildlife cases reported from norther ... | 2014 | 23452510 |
| population structure of two rabies hosts relative to the known distribution of rabies virus variants in alaska. | for pathogens that infect multiple species, the distinction between reservoir hosts and spillover hosts is often difficult. in alaska, three variants of the arctic rabies virus exist with distinct spatial distributions. we tested the hypothesis that rabies virus variant distribution corresponds to the population structure of the primary rabies hosts in alaska, arctic foxes (vulpes lagopus) and red foxes (vulpes vulpes) to possibly distinguish reservoir and spillover hosts. we used mitochondrial ... | 2016 | 26661691 |
| oral vaccination of captive arctic foxes with lyophilized sag2 rabies vaccine. | arctic foxes (alopex lagopus) were immunized with lyophilized sag2 oral rabies vaccine. the effectiveness of this vaccine was determined by serologic response and survival to challenge by rabies virus isolated from a red fox from alaska (usa). no vaccine virus was found in saliva 1-72 hr after ingestion. at 2 wk after vaccination, all foxes had seroconverted, with rabies virus neutralizing antibody levels of 0.2-3.1 iu ml(-1). all vaccinated foxes survived to week 17 after challenge, and hippoca ... | 2004 | 15362836 |
| hair and bone as predictors of tissular mercury concentration in the western alaska red fox, vulpes vulpes. | we evaluated if total mercury (thg) concentrations of keratin-based and bone-based tissues can predict thg concentrations in skeletal muscle, renal medulla, renal cortex, and liver. the thg concentration in matched tissues of 65 red foxes, vulpes vulpes, from western alaska was determined. hair thg concentration had a significant positive correlation with liver, renal medulla, renal cortex, and muscle. the thg concentration for males and females is moderately predictive of thg concentration in t ... | 2015 | 25777958 |
