Bar = 1 μmSalmonella enterica Subspecies enterica Serovar Typhimurium (Salmonella). None of the isolates was resistant to azithromycin at the reference laboratory and no known genes associated with azithromycin resistance were detected in any isolate using WGS.Overestimation of azithromycin resistance is likely to be due to difficulty in interpreting the point of intersection of the ‘trailing edge’ with the gradient strip, used to determine MIC.

Salmonella enterica infections are common causes of bloodstream infection in low-resource areas, where they may be difficult to distinguish from other febrile illnesses and may be associated with a high case fatality ratio. The overall volume of blood cultured is critical to increase yield (isolation rate) of the causative pathogen. Neisseria meningitidis: Properties, Pathogenesis and Laboratory Diagnosis
