|Abstract||27 consecutive isolates of Salmonella recovered from animals between March 1990 and October 1991 were tested for susceptibility to 17 antibiotics using a standard disc diffusion assay. The majority of isolates originated from bovine (44.4%), avian (29.6%) and equine (11.1%) sources. The most common serotype was S. typhimurium (29.6%), followed by S. heidelberg (22.2%) and S.hadar (18.5%). All S. heidelberg and 6 S. typhimurium isolates were susceptible to all of the 17 drugs. No resistance was present among any of the 27 isolates to amikacin, ceftiofur, cephalexin , enrofloxacin, gentamicin, polymyxin B, tobramycin or nalidixic acid. However, some strains were isolated which were capable of transferring multiple resistance to as many as 7 commonly used antimicrobial drugs..|
