Abstract
, floR, strA, and strB. The most common were the strB (18%) and tet(A) (12%) genes that are responsible for coding resistance to aminoglycosides and tetracyclines, respectively. Most of the strains were phenotypically resistant to oxytetracycline (46.88%), neomycin (53.13%) and tylosin (100%). The susceptibility of the investigated Salmonella strains to the bacteriophages was between 33% and 100%. MLST, PCR MP and ERIC PCR analyses indicated a very high genetic similarity of the investigated strains (over 99%). Results of our study indicate that Salmonella enterica ser. Typhimurium is still an important agent in domestic pigeons and that its antimicrobial resistance increases. Alarming is also the confirmation of a single-phase variant 1,4,[5],12:i,-, which could have increased virulence and multi-drug resistance encoded on the plasmid. Most importantly, however, such strains have been isolated from humans with clinical symptoms of Salmonella infection.
