Bovine tracheal organoids for studying Mycoplasma bovis respiratory infections.

In vitro three-dimensional organoid models simulate key aspects of the structure and function of in vivo organs and have been used to study physiology, host-pathogen interactions, pathogenesis and pharmacodynamics. Although most organoid studies have been developed using human or mouse tissues, recent advancements have enabled the establishment of intestinal and respiratory tract organoids from domestic animal samples. Mycoplasma bovis causes chronic respiratory tract infections in cattle with significant health and economic consequences.

A Global Evaluation of Generic Antimicrobial Prescribing Competencies for Use in Veterinary Curricula.

The European Society for Clinical Microbiology and Infectious Diseases (ESCMID) developed consensus-based generic competencies in antimicrobial prescribing and stewardship. These may be useful in structuring and evaluating antimicrobial prescribing education to veterinary students, but their applicability has not been evaluated. We aimed to evaluate whether the ESCMID competencies are currently taught and how relevant they are to veterinary prescribing in veterinary schools globally.

A "plus one" strategy impacts replication of felid alphaherpesvirus 1, and and the metabolism of coinfected feline cells.

Coinfections are known to play an important role in disease progression and severity. Coinfections are common in cats, but no coinfection studies have investigated the dynamics between feline viral and bacterial pathogens. In this study, we performed co-culture and invasion assays to investigate the ability of common feline bacterial respiratory pathogens, and , to replicate in and invade into Crandell-Rees feline kidney cells.

Seeking simplicity, navigating complexity: How veterinarians select an antimicrobial drug, dose, and duration for companion animals.

Background: Minimizing harm from antimicrobials requires use of the narrowest spectrum drug, at an effective dose for the minimum effective duration. Many prescribers are not currently following these guidelines. To address suboptimal antimicrobial use, the underlying reasons must be understood.
