XbaI PFGE-based dendrogram and MDR profiles of representative Salmonella Uganda isolates. Cluster analysis of banding patterns was performed using the Dice similarity coefficient and the unweighted-pair group method. Regions (B to D) and seasons (1, summer; 2, fall; 3, winter; 4, spring) where isolates were observed are indicated, in addition to the percentage of Salmonella Uganda isolates found in that cluster. Antimicrobial abbreviations: Am, amoxicillin-clavulanic acid; Ap, ampicillin; C, chloramphenicol; S, streptomycin; Su, sulfisoxazole; Te, tetracycline; F, cefoxitin; T, ceftiofur; Ax, ceftriaxone; G, gentamicin; K, kanamycin; Sxt, sulfamethoxazole-trimethoprim; Cp, ciprofloxacin; N, nalidixic acid; and Ai, amikacin.
