The investigation of the presence of plasmids was performed on E. coli and Salmonella strains, originating from dogs, cats, cattle, pigs and poultry. The investigated bacterial strains were isolated from ear and skin swabs, vaginal swabs, faeces and urine, obtained from healthy and diseased animals of various age and breed categories. Up to now 45 E. coli and 35 Salmonella strains have been isolated, but the presence of plasmids was investigated in 42 strains of bacteria resistant to at least 3 or more antibiotics (23 E. coli and 4 Salmonella strains).
