The Efficacy of Surrogate Virus Neutralization Test ELISA Varies in the Detection of SARS-CoV-2 Antibodies with Different Postmortem White-Tailed Deer (Odocoileus virginianus) Biological Samples.

The susceptibility of white-tailed deer (WTD; Odocoileus virginianus) to SARS-CoV-2 has resulted in WTD being one of the most studied wildlife species during the COVID-19 pandemic. However, WTD specimen collections for SARS-CoV-2 research and surveillance have largely been opportunistic. Our objective was to evaluate the detection of SARS-CoV-2 neutralizing antibodies (NAbs) in WTD serum, plus two additional WTD biological sample types, using a blocking ELISA previously used for WTD serum.

Duplex PCR assay to determine sex and mating status of Ixodes scapularis (Acari: Ixodidae), vector of the Lyme disease pathogen.

Ticks are a major health threat to humans and other animals, through direct damage, toxicoses, and transmission of pathogens. An estimated half a million people are treated annually in the United States for Lyme disease, a disease caused by the bite of a black-legged tick (Ixodes scapularis Say, 1821) infected with the bacterial pathogen Borrelia burgdorferi. This tick species also transmits another 6 human-disease causing pathogens, for which vaccines are currently unavailable.

Multiple Introductions of the Asian Longhorned Tick () to the United States Revealed Using Mitogenomics.

The Asian longhorned tick (ALT), , is a three-host hard tick native to East Asia. Its opportunistic feeding habits make it an acute agricultural and medical threat, capable of spreading various zoonotic pathogens. An affinity for livestock and companion animals has allowed parthenogenetic populations of ALT to travel to and establish in overseas locations including the United States.

Salmonella environmental persistence informs management relevant to avian and public health.

Salmonellosis is a significant public health threat responsible for millions of human cases annually but is also of significance to domestic and wild animals around the globe. While human infections are often foodborne, an increasing number of cases arise from environmental sources and contact with animals, including wild birds. Understanding the persistence of Salmonella in shared environments is critical for mitigating zoonotic transmission risks and understanding transmission dynamics for pets and free-living wildlife.

Fatal toxoplasmosis in a wild snowshoe hare (Lepus americanus) and eastern gray squirrel (Sciurus carolinensis) from the eastern United States.

Toxoplasmosis is a parasitic disease that exemplifies the One Health interface due to its global distribution and diversity of hosts in which it can infect and potentially cause disease. While T. gondii, the causative agent of toxoplasmosis, has been well-described in many wildlife taxa, including wild and domestic birds and mammals, there is limited published research on clinical disease in wild lagomorphs and rodents.

Living in the city: Angiostrongylus cantonensis is a novel threat to an urban population of Florida burrowing owls (Athene cunicularia floridana) in south Florida.

Background: Angiostrongylus cantonensis, the rat lungworm, is a metastrongyloid parasite that uses rodents as definitive hosts, mollusks as intermediate hosts, and a wide range of invertebrate and vertebrate species as paratenic hosts. Although this parasite poses a significant public health concern in many regions of the world, it can also cause disease in numerous domestic and wildlife aberrant host species. When parasite larvae are ingested by one of these aberrant hosts, larval migration in the central nervous system causes extensive damage, resulting in spinal cord and/or brain damage and inflammation, leading to potentially fatal neurological disease.

Knowledge, attitudes, and practices of Native Americans in northern California regarding ticks and tick-borne diseases.

Reports of tick-borne diseases (TBDs) are increasing worldwide, particularly in North America where a diversity of endemic and exotic tick species and pathogens occur. Native American populations have unique outdoor cultural and occupational practices that may impact their exposure to ticks, yet this risk remains understudied in the context of TBD. To address this gap, we examined knowledge, attitudes, and practices regarding ticks and TBDs among Native American communities in Humboldt County, California.

Multi-season survey of ixodid tick species collected from domestic dogs in Chad, Africa.

Ticks are medically important vectors of pathogens, many of which are zoonotic or impact domestic animal and/or wildlife health. Climate change, landuse modifications, and increasing interactions between domestic animals, wildlife, and humans have resulted in changes in tick-host dynamics and the emergence of novel pathogens worldwide. Therefore, describing the host and geographic ranges of vector species is essential in assessing disease risk, especially in understudied areas, and should be conducted in a One Health context.

An Enigmatic Wild Passerine Mortality Event in the Eastern United States.
