Wild lagomorphs as potential sources of in an urban zoo: a case study.

A 9-y-old captive male Pallas' cat () had a 1-mo history of worsening lameness and was euthanized. The animal was submitted to the North Dakota State University-Veterinary Diagnostic Laboratory for autopsy with differential diagnoses of suspected degenerative joint disease or neoplasia. Autopsy revealed icteric tissues and pinpoint foci in the liver, spleen, and all lung lobes.

A One Health perspective on the use of genotypic methods for antimicrobial resistance prediction.

Antimicrobial resistance is a global One Health concern with critical implications for the health of humans, animals, and the environment. Phenotypic methods of bacterial culture and antimicrobial susceptibility testing remain the gold standards for the detection of antimicrobial resistance and appropriate patient care; however, genotypic-based methods, such as PCR, whole genome sequencing, and metagenomic sequencing, for detection of genes conferring antimicrobial resistance are increasingly available without inclusion of appropriate standards for quality or interpretation. Misleading test results may lead to inappropriate antimicrobial treatment and, in turn, poor patient outcomes and the potential for increased incidence of antimicrobial resistance.

Current state and future directions for veterinary antimicrobial resistance research.

Antimicrobial resistance (AMR) is a critical One Health concern with implications for human, animal, plant, and environmental health. Antimicrobial susceptibility testing (AST), antimicrobial resistance testing (ART), and surveillance practices must be harmonized across One Health sectors to ensure consistent detection and reporting practices. Veterinary diagnostic laboratory stewardship, clinical outcomes studies, and training for current and future generations of veterinarians and laboratorians are necessary to minimize the spread of AMR and move veterinary medicine forward into an age of better antimicrobial use practices.

β-Lactam resistance in veterinary β-hemolytic Streptococcus species: Are we experiencing a public health or test method crisis?

β-Hemolytic Streptococcus (BHS) species are important pathogens with both human and veterinary significance. In human medicine, BHS are considered universally susceptible to β-lactams while BHS of veterinary origin have been reported with up to 8% β-lactam resistance. Recently, veterinary diagnostic laboratories were made aware of significant variability of test method performance for BHS among laboratories.
