ABSTRACT Chronic wasting disease (CWD), a transmissible spongiform encephalopathy of deer, elk, and moose, is the only prion affecting free-ranging animals. Since was first identified in northern Colorado southern Wyoming 1967, new epidemic foci have been 20 additional states, as well two Canadian provinces Republic South Korea. Identification CWD-affected animals currently requires postmortem analysis brain or lymphoid tissues using immunohistochemistry (IHC) an enzyme-linked immunosorbent...
Wildlife rehabilitation is a publicly popular practice, though not without controversy. State wildlife agencies frequently debate the ecological impact of rehabilitation. By analyzing case records, we can clarify and quantify causes for rehabilitation, species involved, treatment outcomes. This data would aid regulatory rehabilitators in making informed decisions, as well gaining insight into mortality. In New York State, Department Environmental Conservation (NYSDEC) has licensed since 1980...
Aspergillus spp. fungal infections are the most common cause of morbidity and mortality in captive penguins. Itraconazole has been drug choice for both therapeutic prophylactic treatment; however, pharmacokinetic pharmacodynamic parameters can be highly variable different species, it not evaluated In this study, four preliminary steady-state trials were performed to compare two oral formulations itraconazole (commercial capsules compared with generic bulk compounded powder) at dosages (6 or...
Abstract Bald eagles ( Haliaeetus leucocephalus ) are considered a recovery success in the United States after rebounding from near extirpation due to widespread use of insecticide dichlorodiphenyltrichloroethane (DDT) twentieth century. Although abundances bald have increased since DDT was banned, other contaminants remained environment with unknown influence on eagle population trends. Ingestion spent lead (Pb) ammunition, source Pb most available and scavengers States, is known kill...
Since the early 1990s there has been an increase in number of cases and geographic expansion severe mange black bear (Ursus americanus) population Pennsylvania. Although are 3 species mites associated with bears, Sarcoptes scabiei identified as etiologic agent these Pennsylvania cases. Historically, S. scabiei-associated bears uncommon sporadic, although it is widespread relatively common canid populations. To better understand this recent emergence sarcoptic nearby states, we genetically...
Lymphoproliferative disease virus (LPDV) is a poorly understood, oncogenic avian retrovirus of domestic turkeys that has historically been restricted to Europe and Israel. However, recent study reported LPDV in multiple wild turkey diagnostic cases from throughout the eastern United States America (USA). To better understand distribution USA, we surveyed 1,164 reportedly asymptomatic hunter-harvested 17 states for presence proviral DNA by PCR. In total, 564/1,164 (47%) were positive LPDV....
Lymphoproliferative disease virus (LPDV) is an oncogenic avian retrovirus that was previously thought to exclusively infect domestic turkeys but recently shown be widespread in Wild Turkeys ( Meleagris gallopavo ) throughout most of the eastern US. In commercial flocks, spreads between birds housed close quarters, there little information about potential risk factors for infection wild birds. Initial studies focused on distribution LPDV nationally, investigation state-level data necessary...
Dynamic interactions between host, pathogen and host-associated microbiome dictate infection outcomes. Pathogens including
Lymphoproliferative disease virus (LPDV) is a retrovirus that infects wild and domestic turkeys ( Meleagris gallopavo ). The first cases of LPDV in the United States were diagnosed 2009, subsequent surveillance has revealed to be widespread turkey populations throughout eastern half country. More research needed determine whether having negative effect on populations, but progress been impeded by lack simple method for diagnosing living birds. Infected animals may appear asymptomatic,...
ABSTRACT Chronic wasting disease (CWD) is a fatal of North American Cervidae. New York State (NYS, USA) successfully managed an outbreak CWD in 2005 both captive and wild white‐tailed deer ( Odocoileus virginianus ) with no reoccurrence the as 2015. To attain maximum compliance efficacy management actions for prevention entry, understanding varied risk perceptions will allow targeted, proactive communication efforts to address divergences between expert‐derived assessments stakeholder...
Abstract While the recent population recovery of bald eagles ( Haliaeetus leucocephalus ) in New York State, USA, is a conservation success, evidence from necropsies suggest that ingested lead (Pb) ammunition fragments causing morbidity and mortality to wild eagles. Wildlife managers officials at State Department Environmental Conservation would benefit analysis their necropsy data understand how documented morbidities or mortalities impact dynamics remaining eagle population. We integrated...
An intact thymic microenvironment is required for the normal maturation and selection of thymocytes. This process directed by interaction thymocyte progenitors with molecules on surface stromal cells cytokines. The precise nature these events poorly understood in humans. We have developed a technique human neonatal organ culture (hNTOC) that enabled development up to 14 days ex vivo culture. hNTOC supported CD4+CD8+ double-positive into both CD4+CD8- CD4-CD8+ single-positive was also used...
Abstract Successful conservation efforts for threatened species depend on accurate characterization of their distribution, habitat use, and threats. However, surveillance can be challenging with small size, cryptic coloring, or elusive behavior. Environmental DNA (eDNA) monitoring provide a sensitive noninvasive alternative to traditional techniques by detecting trace shed target into environment. We evaluated the efficacy eDNA four‐toed salamander ( Hemidactylium scutatum ), terrestrial...
Sera collected from 299 white-tailed deer (Odocoileus virginianus) harvested in New York State by hunters November 2010 were assayed for anti-Toxoplasma gondii IgG antibodies. White-tailed are a useful sentinel risk of human and domestic animal exposure to Toxoplasma oocysts pose potential infection humans other animals ingestion the meat. share grazing space with raised meat likely be exposed horizontal transmission through oocyst consumption, similar species economic concern. Overall,...
Epizootic mortalities in American Crows (Corvus brachyrhynchos) during the winter months, referred to as mortality of crows, have been recorded North America for almost two decades. The most common postmortem findings include necrotizing enteritis, colitis, and fibrinous splenic necrosis. These are proposed be due infection with a Reovirus sp. Our objectives were characterize pathology seasonality epizootics New York State (NYS), confirm causative role an Orthoreovirus sp., determine its...
Abstract Environmental DNA (eDNA) collection has emerged as a powerful and noninvasive wildlife population pathogen‐monitoring tool. Ranavirus is an emerging pathogen linked to die‐offs in amphibian species. Applications of eDNA detection for ranavirus surveillance have shown promise, but it unclear how reliably represents viral pressure on host populations. We evaluated the relationship titers hosts four New York vernal pools from May October 2016. compared aquatic samples ( n = 562) liver...
Several coronaviruses (CoVs) have been detected in domesticated, farmed, and wild meso-carnivores, causing a wide range of diseases infecting diverse species, highlighting their important but understudied role the epidemiology these viruses. Assessing viral diversity hosted wildlife species is essential to understand significance cross-species transmission CoVs. Our focus here was on CoV discovery meso-carnivores Northeast United States as potential "hotspot" area with high density humans...
