原始语种摘要: Abstract(#br)Many microorganisms from various sources may be present in ejaculates of bulls. This study identified and isolated bacteria from bull sperm samples in a commercial stud and evaluated their resistance to antibiotics. The number of colony‐forming units was determined in semen samples collected at distinct steps during freezing and thawing. The minimum inhibitory concentration and the minimum bactericidal concentration were determined for four antibiotics commonly used in commercial studs. A total of 135 microorganisms from 25 genera were isolated. After a sensitivity test, all evaluated microorganisms ( n = 55) were resistant to penicillin and most of them were resistant to tylosin and lincomycin ( n = 54). Resistance to all tested antibiotics was observed in 22% of all...
