Due to the high prevalence of typhoid fever and the periodic nature of Salmonella infections despite the various antimicrobial agents used to treat these infections, the need to open up new strategies for antimicrobial susceptibility rather than the MIC alone arises. This study determines the time-kill curves using four different antimicrobial agents: Gentamicin, Ceftriaxone, Cloxacillin, and Ofloxacin at different concentrations of 1x, 2x, and 4x of their respective MICs. The finding of this study reveals that at 1x MIC, all the antimicrobial agents used, except for Gentamicin, show non-bactericidal activity against the isolates after eight hours of exposure. This study suggests that analyzing the time-kill curves in typhoid fever treatment will help determine the appropriate dose to treat the infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
