Coronaviruses have been documented to replicate in numerous species of vertebrates, and multiple spillovers coronaviruses from animals into humans founded human epidemics. The COVID-19 epidemic likely derived a spillover SARS-CoV-2 bats humans, possibly via an intermediate host.
The ability to rapidly respond wildlife health events is essential. However, such are often unpredictable, especially with anthropogenic disturbances and climate-related environmental changes driving unforeseen threats. Many also short-lived go undocumented, making it difficult draw on lessons learned from past investigations. We report the response a mortality event observed predominantly in wild passerines eastern United States. began May 2021 when rehabilitators private citizens reported...
Zoonotic diseases have received significantly more attention over the last few decades, emerging with increasing frequency and causing majority of notable disease outbreaks in this century, including COVID-19 pandemic. As human activities shifting climate patterns induce changes environment that alter habitat range reservoir species, potential for animal interactions will increase enhance opportunity spillover. Thus, any emergency response preparedness planning must take into account...
In 2014, antimicrobial drug-resistant Campylobacter jejuni sequence type 6964 emerged contemporaneously in poultry from 3 supply companies the North Island of New Zealand and as a major cause campylobacteriosis humans Zealand. This lineage, not previously identified Zealand, was resistant to tetracycline fluoroquinolones. Genomic analysis revealed divergence into 2 clades; both clades were associated with human infection, 1 A B other company C. Accessory genome evolution plasmid, phage...
Abstract There is a growing need for collaborative and interdisciplinary research in addressing global ecological challenges, early career researchers ( ECR s) often play vital role such ventures. But despite the desire approaches, forming new collaborations risky, disproportionately so s, whose perspectives on this topic are rarely heard. Here, we present common perceptions among s regarding opportunities intra‐ collaboration, barriers preventing collaboration from taking place. We also...
Introductory paragraph The SARS-CoV-2 pandemic likely began by viral spillover from animals to humans 1-3 ; today multiple animal species are known be susceptible infection 4-8 . White-tailed deer, Odocoileus virginianus infected in North America at substantial levels 9-11 , and genomic data suggests that a variant deer may have spilled back 12,13 Here we characterize Pennsylvania (PA) sampled during fall winter 2021. Of 123 nasal swab samples analyzed RT-qPCR, 20 (16.3%) were positive for...
Infectious bovine keratoconjunctivitis (IBK), commonly known as pinkeye, has a marked negative impact on the economy of cattle industry. Moraxella species, including Mor. bovis and bovoculi, which have been associated with this disease, colonize clinically healthy eyes well, suggesting that there are intrinsic changes may occur to ocular microbiota or involvement additional unrecognized organisms contribute IBK. To evaluate this, 104 swabs collected from IBK 16 different herds were subjected...
Aims: To collect baseline data on the contact risk pathways and biosecurity practices of commercial poultry farms in New Zealand, investigate relationship between farm-level disease risks practices, identify important health concerns producers.Methods: A cross-sectional survey all registered Zealand operations was conducted 2016 collecting information farm demographics, pathways. Survey responses were used to generate an unweighted subjective score based eight criteria a frequency with which...
Mass mortality events in wildlife can be indications of an emerging infectious disease. During the spring and summer 2021, hundreds dead passerines were reported across eastern US. Birds exhibited a range clinical signs including swollen conjunctiva, ocular discharge, ataxia, nystagmus. As part diagnostic investigation, high-throughput metagenomic next-generation sequencing was performed three molecular laboratories on samples from affected birds. Many potentially pathogenic microbes...
Staphylococcus aureus is one of the leading causes bovine mastitis worldwide and a common indication for use antimicrobials on dairy farms. This study aims to investigate association between on-farm antimicrobial usage resistance (AMR) profiles mastitis-causing S. aureus. Whole-genome sequencing was performed 57 isolates derived from cows with either clinical or subclinical 17 herds in New Zealand. The genetic relatedness examined using core single nucleotide polymorphism alignment whilst...
To assess the current level of engagement between backyard poultry keepers and veterinarians in New Zealand; to understand opportunities barriers for improving access health care; gauge interest participating a voluntary national information system.Backyard were defined as any bird species kept non-commercial purposes. Separate cross-sectional surveys administered Zealand over 12-week periods starting 22 March 2021 03 May respectively. The veterinarian survey was advertised monthly update...
Understanding the relative contribution of different between-farm transmission pathways is essential in guiding recommendations for mitigating disease spread. This study investigated association between contact linking poultry farms New Zealand and genetic relatedness antimicrobial resistant Campylobacter jejuni Sequence Type 6964 (ST-6964), with aim identifying most likely that contributed to its rapid spread across industry. Whole-genome sequencing was performed on 167C. ST-6964 isolates...
White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans, has decimated bat populations across North America. Despite ongoing management programs, WNS continues to expand into new populations, including in US states previously thought be free from pathogen and disease. This expansion highlights a growing need for surveillance tools that can used enhance existing monitoring programs support early detection of P. destructans areas. We evaluated feasibility using handheld,...
Abstract In 2021, news outlets and state natural resources agencies reported a large number of avian deaths across several states in the eastern midwestern USA. This event fomented rapid robust response from animal health experts country. Given clustered pattern disease death, an infectious etiology was rigorously investigated. No single causative pathogen identified, leaving cause thus epidemiology mortality unex-plained. this study, we attempted to hone on potential causes or contributors...

Tick paralysis is a caused by bites from Ixodes holocyclus, affecting an estimated 10,000 companion animals in Australia annually. Despite tick antiserum being the cornerstone of treatment, there are no large-scale general practice studies that examine survival outcomes antiserum-treated animals. In this retrospective study, clinical records three far north Queensland veterinary clinics were searched for canine and feline patients seen between 2000 2020. Patient assessed outcomes, then...
