Article Synopsis
  • Zika virus (ZIKV) is a public health threat with outbreaks in various regions, but its impact on chickens remains unclear.
  • A study found that while younger chickens can be infected with ZIKV, they show no clinical signs and rapid viral clearance, with older chickens being resistant to infection altogether.
  • The results suggest that chickens do not have a significant role in ZIKV epidemiology, indicating their limited susceptibility to the virus.

Article Synopsis
  • * Genomic data was used to trace the transmission history of SARS-CoV-2 between humans and deer, revealing no direct evidence of deer transmitting the virus back to humans, but indicating a low detection rate of cases at only 4.2%.
  • * The significant spread of the virus within deer populations and unsampled cases suggests a need for ongoing monitoring and surveillance where humans and animals interact to prevent potential spillback to humans.

Article Synopsis
  • Many animal species, including white-tailed deer, can contract SARS-CoV-2, and there’s evidence that deer can transmit the virus to one another.
  • A study conducted in Iowa from April 2020 to January 2021 found that 33.2% of sampled deer tested positive for SARS-CoV-2 RNA, with a significant spike during the peak of human cases and the deer hunting season.
  • The research identified 12 lineages of the virus in deer, suggesting multiple instances of human-to-deer transmission, indicating a need for a comprehensive "One Health" approach to better understand how SARS-CoV-2 spreads among animals and humans.

Metagenomic sequencing of clinical diagnostic specimens has a potential for unbiased detection of infectious agents, diagnosis of polymicrobial infections and discovery of emerging pathogens. Herein, next generation sequencing (NGS)-based metagenomic approach was used to investigate the cause of illness in a subset of horses recruited for a tick-borne disease surveillance study during 2017-2019. Blood samples collected from 10 horses with suspected tick-borne infection and five apparently healthy horses were subjected to metagenomic analysis.

Staphylococcus pseudintermedius is a pathogen of veterinary importance, as it is the major causative agent of superficial pyoderma in dogs. We present the complete genome sequences of six strains of S. pseudintermedius derived from dogs affected with epidermal collarettes and superficial bacterial folliculitis, which are two variants of superficial pyoderma.

(historically called ) causes infectious coryza (IC), which is an acute respiratory disease of chickens. Recently, outbreaks of IC have been reported in Pennsylvania (PA) in broilers, layer pullets, and laying hens, causing significant respiratory disease and production losses. A tentative diagnosis of IC can be made based on history, clinical signs, and characteristic gross lesions.

A total of 163 S. aureus isolates; 113 from mastitic milk (MM) and 50 from bulk tank milk (BTM) (2008, 2013-2015) submitted for bacteriologic analysis at the Penn State Animal Diagnostic Laboratory were examined for their phenotypic and genotypic characteristics. Multi-locus sequence typing (MLST) analysis identified 16 unique sequence types (STs) which belonged to eight clonal complexes (CCs).

subspecies , a zoonotic bacterial pathogen caused a series of outbreaks with high mortality affecting swine herds in multiple locations of the USA and Canada in 2019. Further genetic analysis revealed that this agent clustered with ATCC 35246, a strain associated with high mortality outbreaks in swine herds of China originally reported in 1977. Rapid and accurate diagnosis is absolutely critical for controlling and limiting further spread of this emerging disease of swine.

, the causative agent of infectious coryza, causes significant economic losses to the poultry industry due to increased culling rates in growing chickens and decreased egg production in layers. We present the complete genome sequences of seven strains of isolated from poultry farms in Pennsylvania during 2019.

Avian influenza viruses (AIVs) cause major economic losses to the global poultry industry. Many host factors have been identified that act as regulators of the inflammatory response and virus replication in influenza A virus (IAV) infected cells including nucleotide-binding oligomerization domain (NOD) like receptor (NLR) family proteins. Evidence is emerging that NLRC5, the largest NLR member, is a regulator of host immune responses against invading pathogens including viruses; however, its role in the avian immune system and AIV pathogenesis has not been fully explored.

resistance to extended-spectrum cephalosporins (ESC) conferred by cefotaximases () is a growing concern in the United States. Among food-producing animals, poultry are a major reservoir of ESC-resistant . A retrospective study was carried out to further characterize 38 ceftiofur-resistant clinical isolates obtained from poultry during 2007-2018.

Bovine herpesvirus-1 (BoHV-1) is a major pathogen affecting cattle worldwide causing primarily respiratory illness referred to as infectious bovine rhinotracheitis (IBR), along with reproductive disorders including abortion and infertility in cattle. While modified live vaccines (MLVs) effectively induce immune response against BoHV-1, they are implicated in disease outbreaks in cattle. Current diagnostic methods cannot distinguish between MLVs and field strains of BoHV-1.

Consumption of shell eggs has been associated with Salmonella Enteritidis (SE) infections in humans in the United States. Because of this, the Pennsylvania Egg Quality Assurance Program (PEQAP) was developed and implemented in 1994. The PEQAP involves periodic flock testing and management practices to minimize SE contamination of shell eggs.

Classical swine fever (CSF) is a highly contagious and potentially fatal disease of domestic pigs. Classical swine fever is routinely diagnosed by clinical signs, serology, detection of CSF virus (CSFV) nucleic acid by PCR and virus isolation. Most of the current CSF diagnostic methods are expensive and have an extended turnaround time.
