The Wild Turkey (Meleagris gallopavo) is a geographically widespread, popular game bird and conservation icon in North America. Following successful reestablishment parts of the US Canada, regional declines have fueled population health concerns; therefore, understanding mortality causes spatiotemporal patterns disease important to uncover potential ongoing future risks. Histomonosis, caused by trichomonad Histomonas meleagridis, well-established potentially fatal Turkeys; however, its...
Significance Within eastern North America, distributions of vector-transmitted haemosporidian blood parasites birds, commonly known as “avian malaria parasites,” are associated with the their host species independently direct effects climate on potential vectors. Spatial analyses additionally indicated an absence dispersal limitation for these parasites. Finally, host-breadth, ranging continuously from specialist to generalist, varies among parasite lineages and is dynamic within assemblages...
Aspergillosis is the most commonly and widely reported fungal infection in birds. Disease development often secondary to stressors that cause immunocompromise, it typically regarded as a disease of captivity. We retrospectively evaluated data from 133 birds diagnosed with aspergillosis at Southeastern Cooperative Wildlife Study 2001-2023 assess diversity relative frequency across avian taxa, gross histologic lesion patterns, comorbidities. Of 10 taxonomic orders represented, Charadriiformes...
Arthropod-borne viruses (arboviruses) are a taxonomically varied group of that affect the health many avian species, including ruffed grouse (Bonasa umbellus), popular upland game bird whose numbers in decline portions its range. Hunter-harvested tissue samples were tested for arboviruses during 2018-2022 hunting seasons Michigan, Minnesota, and Wisconsin, USA. A low percentage harvested infected with West Nile virus (8/1892; 0.4%), eastern equine encephalitis (18/1892; 1.0%), Highlands J...
The Northern Bobwhite (Colinus virginianus) has been undergoing a range-wide population decline. Potential causes for declines across its historic range have investigated decades and include habitat loss fragmentation variety of parasitic infectious diseases. Although there studies on bobwhite ecology in Oklahoma, USA, relatively little is known about parasites pathogens the region. We evaluated health free-ranging bobwhites from nine sites western Oklahoma. From 2018 to 2020, 206 were gross...
Interest in causes of mortality free-ranging, native North American lagomorphs has grown with the emergence rabbit hemorrhagic disease virus 2 (RHDV2). Over years 2013-2022, Southeastern Cooperative Wildlife Disease Study received 119
West Nile virus (WNV) has been implicated in regional declines of numerous North American bird species, although its potential impact upon many including some game birds, remains unknown. Specifically, information about susceptibility to infection and outcome are crucial assessing health risks. Northern bobwhite quail (Colinus virginianus) a popular common across much the United States, as well captive breeding programs backyard birds. Two age groups bobwhites were subcutaneously inoculated...
West Nile virus (WNV) was introduced to North America two decades ago, but for many species, including Ruffed Grouse (Bonasa umbellus), the effects of WNV on individuals and populations remain poorly understood. Recent studies suggest effect might vary among geographic regions, depending habitat conditions. We studied in Minnesota, US, during 2018–19, a region known have abundant population cycling around stable long-term average. worked with cooperating hunters collect hearts, feathers,...
Arthropod-borne viruses (arboviruses) are globally widespread, and their transmission cycles typically involve numerous vertebrate species. Serologic testing of animal hosts can provide a routine surveillance approach to monitoring disease systems, alternative arthropod human case reports, may augment knowledge epizootiology. Wild captive ruminants represent good candidate sentinels track geographic distribution prevalence select arboviruses. They often geographically widespread abundant,...
Abstract Since its introduction to the United States in 1999, West Nile virus (WNV) rapidly spread and is now endemic throughout much of North America. has impacted many American birds, including suspected population‐level declines. However, potential effects WNV on upland game bird species remain largely unknown. We reviewed published literature infection with majority comprised experimental trials, serologic surveys, natural reports. Early research indicated that some within Galliformes...
Abstract There are increasing concerns about the effects of disease on wild turkeys ( Meleagris gallopavo ). Yet, many management agencies lack adequate data turkey diseases and pathogens to address this concern. Toward that end, Pennsylvania Game Commission increased surveillance efforts beginning in 2013 (referred hereafter as enhanced period). From 2008–2018, 121 from were submitted for necropsy, with 102/121 (84.3%) during period (2013–2018). We examined cases determine causes...
West Nile virus (WNV) is pathogenic in a wide range of avian hosts and endemic much North America. This responsible for population declines some Passeriformes. We describe WNV-associated mortality event American White Ibis (Eudocimus albus) nestlings. species, inherent to the Everglades ecosystem, which has recently begun nesting urban areas. An colony south Florida was monitored from March–July 2020 as part an ongoing study. Nestling carcasses were collected opportunistically sent...
Mange is a contagious skin disease caused by different mite species affecting numerous domestic and wild animals, worldwide. This report details notoedric mange in an eastern cottontail (Sylvilagus floridanus) marsh rabbit palustris) from Florida, USA. Clinical examination revealed similar gross lesions including poor nutritional condition, multifocal alopecia hyperkeratosis. Skin scrapings both rabbits subcutaneous mites identified as Notoedres centrifera, previously only associated with...
Since the introduction of West Nile virus (WNV) to North America in 1999, WNV is estimated have contributed population-level declines numerous avian species. However, potential impacts this on many free-ranging upland game bird species, including wild turkey (Meleagris gallopavo), which undergoing regional population declines, remain unknown. Herein, two age groups (∼5 6 weeks and ∼15 16 post-hatch) juvenile turkeys were subcutaneously inoculated with WNV, sampled daily from 1 7 days...
Trichomonas gypaetinii was detected in 117 (88%) of 133 Bald Eagles (Haliaeetus leucocephalus) and 0/7 Golden (Aquila chrysaetos) the USA, with no sex or age prevalence difference. All eagles lacked associated lesions. This study indicated that T. is common widespread Eagles, but rarely disease.

Listeria monocytogenes is a bacterium that can cause disease in many species, including humans, livestock, and wildlife. Increased interactions via shared habitats may promote pathogen transmission among these groups. Our objectives were to evaluate the Southeastern Cooperative Wildlife Disease Study diagnostic data characterize compare L. monocytogenes-induced lesions comorbidities gray foxes wild turkeys, describe cases of listeriosis 2 cervids. From 1991-2020, 8 foxes, neonatal elk,...
Ruffed Grouse (Bonasa umbellus) populations have declined in much of the eastern US recent decades. Research suggests that West Nile virus (WNV) contributed to these declines, based on decreasing population indices temporally correlated WNV introduction into North America, high morbidity and mortality experimentally infected Grouse, relatively low statewide seroprevalence concurrent with vector indices. We describe lesions relevant diagnostic findings six, free-ranging directly or indirectly...
The frequency of arthropod-borne viral disease in naïve hosts is subject to change based on complex interactions among vector, host, virus, and external factors (e.g., climate). Thus, continual monitoring for both susceptibility host infection dynamics needed, especially viruses that have proven detrimental the health wildlife conservation concern. Greater Sage-grouse (Centrocercus urophasianus) a gamebird ecological economic importance western United States which population declines led...
