RT Journal Article T1 Highly Tigecycline-Resistant Klebsiella pneumoniae Sequence Type 11 (ST11) and ST147 Isolates from Companion Animals A1 Martinez Ovejero, Cristina A1 Escudero García-Calderón, José Antonio A1 Thomas-Lopez, Daniel A1 Hoefer, Andreas A1 Moyano, Gabriel A1 Montero Serra, Natalia A1 Martín Espada, María Del Carmen A1 González Zorn, Bruno AB In this study, we characterized two tigecycline-resistant Klebsiella pneumoniae isolates from dog urine samples. The isolates were genetically unrelated, belonging to sequence type 11 (ST11) and ST147, both classically related to human isolates. To the best of our knowledge, this is the first identification of tigecycline-resistant isolates from animals. We unveil here the worrisome circulation among animals of bacterial clones resistant to this last-resort antibiotic.
