Extremely Drug-Resistant Salmonella enterica Serovar Senftenberg Infections in Patients in Zambia. Extremely Drug-Resistant Salmonella enterica Serovar Senftenberg Infections in Patients in Zambia

Two cases of extremely drug-resistant Salmonella enterica serovar Senftenberg isolated from patients in Zambia were investi- gated by utilizing MIC determinations and whole-genome sequencing. The isolates were resistant to, and harbored genes to- ward, nine drug classes, including fluoroquinolones and extended-spectrum cephalosporins, contained two plasmid replicons, and differed by 93 single-nucleotide polymorphisms.
