In vitro antibiotic susceptibility of Dutch Mycoplasma synoviae field isolates originating from joint lesions and the respiratory tract of commercial poultry

International audience ; The in vitro susceptibility of 17 Dutch Mycoplasma synoviae field isolates, 3 originating from joint pathology and 14 from the respiratory tract of commercial poultry, for enrofloxacin, difloxacin, doxycycline, tylosin and tilmicosin was examined. The M. synoviae ATCC 25204 was included as a control strain. The antibiotic susceptibility was tested quantitatively using the broth microdilution test. Based on initial and final MIC values, all tested isolates were susceptible to doxycycline, tylosin and tilmicosin. Two isolates from the respiratory tract were resistant to... Mehr ...
