## 3 Results  
The examined pathogens were found in 54 (71.1%) of the 76 tested samples. _S. aureus_, CoNS and _E. coli_ were detected in 14.5% (11 of 76), 38.2% (29 of 76) and 18.4% (14 of 76) of the samples, respectively. In 3 cases (3.9%, 3 of 76), which corresponded to samples collected from milking shells, the result of the analysis was positive for both _E. coli_ and CoNS. The percentage of positive samples in the study farms was 88.2% in Farm A (15 of 17), 33.3% in Farm B (1 of 3), 66.7% (14 of 21) in Farm C, 88.2% in Farm D (15 of 17), and 50% (9 of 18) in Farm E. The lowest percentage of samples positive to _E. coli_ was recorded in Farm B (0%, 0 of 3), whereas the highest was recorded in Farm D (29.5%, 5 of 17). The relevant percentages recorded for _Staphylococci_ was 33.3% (1 of 3) in Farm B and 76.5% (13 of 17) in Farm A (Table 1).  
The percentage of isolates of the study pathogens that were characterised as AMR of those detected was 27.8% (15 of 54), corresponding to 30% (12 of 40) of _Staphylococci_ [33.3% (4 of 12) _S. aureus_, 66.7% (8 of 12) CoNS] and 21.4% (3 of 14) of _E. coli_. None (\(n=0\)) of the 3 _E. coli_ AMR isolates and 6 of the 12 AMR _Staphylococci_ isolates were characterised as MDR (50%) [25% (1 of 4) _S. aureus_, 62.5% (5 of 8) CoNS]. All the AMR _Staphylococci_ isolates (100%, 12 of 12) and 2 of the 3 (66.7%) AMR _E. coli_ isolates were detected in the milking shells. The other AMR _E. coli_ isolate was detected in a sample of feed (33.3%, 1 of 3). The number of AMR _Staphylococci_ isolates of the total number of _Staphylococci_ detected per farm was 1 of 13 (7.7%) in Farm A, 0 of 1 (0%) in Farm B, 4 of 9 (44.4%) in Farm C, 6 of 10 (60%) in Farm D, and 1 of 7 (14.3%) in Farm E. The relevant percentages with regards to _E. coli_ were 2 of 2 (100%) in Farm A, and 1 of 2 (50%) in Farm E (Tables 2 and 3). The number of MDR _Staphylococci_ isolates of the total number of those characterised as AMR per farm was 1 of 1 (100%) in Farm A, 1 of 4 (25%) in Farm C, 4 of 6 (66.7%) in Farm D, and 0 of 1 (0%) in Farm E. None of the _E. coli_ AMR isolates were characterised as MDR (Tables 2 and 3).
