Ticks and tick-borne microbes identified through passive and active surveillance in Alaska.

Rapid environmental change in Alaska and other regions of the Arctic and sub-Arctic has raised concerns about increasing human exposure to ticks and the pathogens they carry. We tested a sample of ticks collected through a combination of passive and active surveillance from humans, domestic animals, and wildlife hosts in Alaska for a panel of the most common tick-borne pathogens in the contiguous United States to characterize the diversity of microbes present in this region. We tested 189 pooled tick samples collected in 2019-2020 for Borrelia spp.

Establishing a baseline for tick surveillance in Alaska: Tick collection records from 1909-2019.

The expanding geographic ranges of tick species that are known pathogen vectors can have implications for human, domestic animal, and wildlife health. Although Alaska is home to several hard tick species, it has historically been outside of the range of the most common medically important ticks in the contiguous United States and western Canada. To assess the status of tick species establishment in the state and to provide a baseline for tracking future change in the distribution of ticks, we reviewed and compiled historical tick records and summarized recent tick occurrence records collected through the development of the Alaska Submit-A-Tick Program and through tick drag sampling at sentinel sites in southcentral Alaska.

Medical Encounters for Youth With Autism Spectrum Disorder: A Comprehensive Review of Environmental Considerations and Interventions.

Approximately 1 in 59 youth are currently diagnosed with autism spectrum disorder (ASD), a neurodevelopmental disorder. In comparison to typically developing peers, youth with ASD encounter hospitalization at higher rates due to their heightened health care needs. While visiting the hospital is a stressor for youth with neurotypical needs, the experience contains unique challenges for those with ASD.

Clinical, culture, serology, and histopathology outcomes of bighorn sheep experimentally infected with Brucella ovis.

Disease caused by Brucella ovis has not been previously reported in bighorn sheep (BHS; Ovis canadensis canadensis). Antibodies to B. ovis, however, are occasionally detected in free-ranging BHS, and this has been a concern for managers involved in translocation programs.
