Antimicrobial susceptibility pattern to disinfectants in Pseudomonas aeruginosa strains isolated from dairy sheep breeds in Sardinia

Introduction - Pseudomonas aeruginosa is still one of the leading causes of morbidity in dairy animals and particularly associated with severe clinical forms of mastitis. Its outstanding capacity to evade the activity of antimicrobial prophylaxis makes this species one of the most feared pathogens. In this context the World Health Organization (WHO) has reported this pathogen in a catalogue of bacteria that pose the greatest threat to human health. Thus, an accurate disinfection procedure is needed to avoid the incidence of Pseudomonas- related diseases in veterinary as well as in human medicine. Aim - The aim of this study was to evaluate the antimicrobial resistance patterns to common disinfectants in P. aeruginosa strains isolated from ovine breeding farms in Italy.
