a

Gut contents and organs are from necropsy specimens.

b

AMP, ampicillin; AMC, amoxicillin-clavulanic acid; CHL, chloramphenicol; CTX, cefotaxime; ENO, enrofloxacin; FOX, cefoxitin; GEN, gentamicin; KAN, kanamycin; NAL, nalidixic acid; SPT, spectinomycin; STR, streptomycin; SXT, sulfometoxazole-trimethoprim; SUL, sulfonamides; TET, tetracycline;

c

ND, not determined. PFGE patterns differing for more than three DNA fragments were classified as different profiles.

d

blaTEM genes were identified by PCR, although several amplicons were sequenced identifying blaTEM-1a and blaTEM-1b gene variants.
