| in vitro susceptibility of 21 antimicrobial agents to 37 isolates of brachyspira hyodysenteriae isolated from pigs in okinawa prefecture. | the in vitro susceptibilities to 21 antimicrobial agents, of 37 isolates of brachyspira (b.) hyodysenteriae isolated from pigs in okinawa meat center and a pig farm in okinawa prefecture, japan, were determined by the agar dilution method. carbadox was the most active of all the agents tested against the isolates (mic: <0.003 to 0.05). all the isolates were highly susceptible to olaquindox, tiamulin, dimetridazole, efrotomycin and valnemulin with mics ranging from </=0.1 to 1.6 microg/ml. penici ... | 2004 | 15107563 |
