Landscape Seroprevalence of Three Hemorrhagic Disease-Causing Viruses in a Wild Cervid
AbstractDisease plays a major role in shaping wildlife populations worldwide, and changes in landscape conditions can significantly influence risk of pathogen exposure, a threat to vulnerable wild species. Three viruses that cause hemorrhagic disease affect cervid populations in the USA (Odocoileus hemionus adenovirus, bluetongue virus, and epizootic hemorrhagic disease virus), but little is known of their distribution and prevalence in wild populations. We explored the distribution and co-occurrence of seroprevalence of these three pathogens in southern mule deer (Odocoileus hemionus fuliginatus), a subspecies of conserva...

Prevalence and Antibiotic Resistance of Campylobacter spp. in Urban and Rural Black-Headed Gulls Chroicocephalus ridibundus
AbstractWe investigate the role of black-headed gulls (Chroicocephalus ridibundus), an omnivorous species that is among the most likely wild bird candidates for transmission of zoonotic agents, as a potential reservoir ofCampylobacter spp. Colonies with different anthropogenic pressures were studied to examine differences in exposure to sources ofCampylobacter between rural and urban birds. We recordedCampylobacter spp. in 4.87% of adult black-headed gulls and 2.22% of their chicks after analysing 1036 cloacal swabs collected over two breeding seasons in three colonies in northern Poland.Campylobacter jejuni was found most...

Climatic Factors Influencing the Anthrax Outbreak of 2016 in Siberia, Russia
AbstractIn 2016, an outbreak of anthrax killing thousands of reindeer and affecting dozens of humans occurred on the Yamal peninsula, Northwest Siberia, after 70 years of epidemiological situation without outbreaks. The trigger of the outbreak has been ascribed to the activation of spores due to permafrost thaw that was accelerated during the summer heat wave. The focus of our study is on the dynamics of local environmental factors in connection with the observed anthrax revival. We show that permafrost was thawing rapidly for already 6 years before the outbreak. During 2011 –2016, relatively warm years were followed...

Assessment of Environmental Hazards to Public Health in Temperate Urban Argentina
AbstractHuman health risk in urban areas depends on multiple environmental features. We performed a year-round survey in a highly urbanized district located in temperate Argentina (General San Mart ín, Buenos Aires) to establish baseline information about environmental hazards associated with health risks. Sampling was stratified into low and high hazardous zones according to estimated indexes previously developed for the area for four hazards: drinking water and air pollution, and mosquito a nd rodent infestation.

Movements of Indian Flying Fox in Myanmar as a Guide to Human-Bat Interface Sites
AbstractFrugivorous bats play a vital role in tropical ecosystems as pollinators and seed dispersers but are also important vectors of zoonotic diseases. Myanmar sits at the intersection of numerous bioregions and contains habitats that are important for many endangered and endemic species. This rapidly developing country also forms a connection between hotspots of emerging human diseases. We deployed Global Positioning System collars to track the movements of 10 Indian flying fox (Pteropus giganteus) in the agricultural landscapes of central Myanmar.

Site Fidelity is Associated with Food Provisioning and Salmonella in an Urban Wading Bird
AbstractFood provisioning can change wildlife pathogen dynamics by altering host susceptibility via nutrition and/or through shifts in foraging behavior and space use. We used the American white ibis (Eudocimus albus), a wading bird increasingly observed in urban parks, as a model to study synergistic relationships between food provisioning and infection risk across an urban gradient in South Florida. We tested whetherSalmonella prevalence was associated with changes in ibis diet (stable isotope analysis), space use (site fidelity via GPS tracking), and local density (flock size). We compared the relative importance of the...

Effects of Waning Maternal Immunity on Infection Dynamics in Seasonally Breeding Wildlife
We examined how the population structure, influenced by seasonal breeding and maternally derived immunity, affects viral invasion and persistence using a hypothetical system based on Hendra virus infection in black flying foxes (Pteropus alecto). A deterministic Hendra virus epidemic model with uncertainty in parameter values was used to simulate transient epidemics following viral introduction into an infection-free population, including various timings within a year and differences in pre-existing seroprevalence. Additionally, we applied different modelling methods of waning maternal immunity to examine whether different...

Sarcocystis neurona Transmission from Opossums to Marine Mammals in the Pacific Northwest
AbstractIncreasing reports of marine mammal deaths have been attributed to the parasiteSarcocystis neurona. Infected opossums, the only known definitive hosts, shedS. neurona sporocysts in their feces. Sporocysts can contaminate the marine environment via overland runoff, and subsequent ingestion by marine mammals can lead to fatal encephalitis. Our aim was to determine the prevalence ofS. neurona in opossums from coastal areas of Washington State (USA) and to compare genetic markers betweenS. neurona in opossums and marine mammals. Thirty-two road-kill opossums and tissue samples from 30 stranded marine mammals meeting in...

AbstractA total of 55 samples of intestinal contents from 28 raccoon dogs (Nyctereutes procyonoides) and 27 badgers (Males anakuma) in Miyazaki prefecture, Japan, were examined for the presence ofCampylobacter species.C. jejuni andC. upsaliensis were isolated from 3.6% (n = 1) and 75% (n = 21) of raccoon dogs, respectively. In contrast, noCampylobacter spp. was isolated from the badgers examined. TheC. upsaliensis isolates were subjected to antimicrobial susceptibility testing against 8 antimicrobial agents. This revealed that most of the isolates from raccoon dogs were susceptible to the antimi...

Ecological and Conservation Significance of Herpesvirus Infection in Neotropical Bats
AbstractBats are the second most diverse order of mammals and key species for ecosystem functioning, providing a wide range of ecosystem services, from pest control to seed dispersal. Chiropterans are known for hosting a large diversity of viruses, in some cases with little or no effect to their health. Here, we report on the results of a screening for DNA (Herpesviridae) and RNA viruses (Rhabdovirus and Pneumovirus), finding a high prevalence and wide diversity of both Beta- and Gamma-Herpesvirus in insectivorous and hematophagous bats of the southern cone of South America.

Active Forest Management Reduces Blacklegged Tick and Tick-Borne Pathogen Exposure Risk
AbstractIn the northeastern USA, active forest management can include timber harvests designed to meet silvicultural objectives (i.e., harvesting trees that meet certain maturity, height, age, or quality criteria). Timber harvesting is an important tool in enhancing regeneration and maintaining forest health. It also has considerable potential to influence transmission dynamics of tick-borne pathogens, which are deeply embedded in the forest ecosystem. We conducted a 2-year study to test the hypotheses that recent timber harvesting impacts blacklegged tick density and infection prevalence in managed nonindustrial forests. ...
