First report of Salmonella enterica serotype paratyphi A azithromycin resistance leading to treatment failure

The prevalence of Salmonella enterica serotype Paratyphi A infection is increasing, and multidrug resistance is a well-recognized problem. Resistance to fluoroquinolones is common and leads to more frequent use of newer agents like azithromycin. We report the first case of azithromycin resistance and treatment failure in a patient with S. Paratyphi A infection.
