Exploring the dog microbiome for therapeutic potential in the treatment of canine bacterial pyodermaStudent Research Project Grant: £2,800 awarded in 2024 Institution: University of Liverpool Lead researcher: Vanessa Schmidt Bacterial and fungal infections of the skin are among the most common diseases seen in small animal Aim: This undergraduate project aims to identify and characterise commensal bacteria with therapeutic potential against Staphylococcus pseudintermedius, the most common cause of bacterial skin infections in dogs. This will help determine mechanisms of inhibition and their potential for clinical application. |

Is IgA deficiency a feature of canine atopic dermatitis in small and medium sized dogs?Master’s Degree by Research Grant: £39,365 awarded in 2023 Institution: Scottish Rural College/University of Edinburgh Lead researcher: Francesca Soutter Canine atopic dermatitis is a common, genetically predisposed and chronic skin condition in dogs characterised by pruritus and inflammation. Aim: This study aims to improve the understanding of underlying mechanisms of atopic skin disease in small and medium breed dogs to help in the development of new treatment strategies and the reduction in antimicrobial use. |

Fungal dysbiosis following antibacterial monotherapy in canine otitis externaClinical Research Project Grant: £6650 awarded in 2021 Institution: RVC Lead researcher: Ross Bond Secondary ear infections with bacteria or Malassezia yeasts commonly exacerbate the clinical signs of the initial infection and complicate the treatment. While the use of drugs to treat the primary bacterial infection may be effective, they can lead to Malassezia overgrowth. Aim: This prospective study will characterise this fungal dysbiosis to better inform treatment decisions in canine otitis externa. Findings showed that yeast populations may opportunistically increase in dogs’ ears following broad spectrum antibacterial treatment for chronic otitis externa, and are published in the Journal of Small Animal Practice. |

Evaluation of antimicrobial activity of canine urinary extracellular vesicles against causative agents of canine otitis externa (Pseudomonas aeruginosa and Staphylococcus aureus)Student Research Project Grant: £3180 awarded in 2023 Institution: University of Cambridge Lead researcher: Tim Williams Bacterial species that cause canine otitis externa are becoming increasingly antibiotic resistant. Take home message: This undergraduate project demonstrated the significant antimicrobial activity of canine urinary extracellular vesicle preparations against P. aeruginosa and S. intermedius, suggesting they could provide a novel topical therapeutic against these species. Findings were presented as an abstract at BSAVA Congress 2024, which can be freely accessed here. |

Exploring the dog microbiome for therapeutic potential of skin diseaseStudent Research Project Grant: £3000 awarded in 2022 Institution: University of Liverpool Lead researcher: Vanessa Schmidt Microflora dysbiosis, with resultant staphylococcal infection, is common in atopic dermatitis. This undergraduate study investigated the inhibition of staphylococci by co-inhabiting microbes. Bacterial isolates from skin swabs of dogs with atopic dermatitis were used in competition tests against clinical isolates of S. pseudintermedius. Take home message: Five bacterial isolates showed consistent inhibition of S. pseudintermedius, with S. warneri and S. epidermidis showing the largest inhibition zones. Findings were presented as an abstract at BSAVA Congress 2023, which can be freely accessed here. |
