Note: the total number of isolates and the percentage are reported. Species distribution considering dogs (n = 746) and cats (n = 194) is also described. For every bacterial species considered, the percentage and the total number of AMR and MDR isolates is reported. The row “others” includes bacterial species with less than 10 isolates.
