 Isolates are categorized into susceptible, intermediate, and resistant according to the guidelines provided by the CLSI. Isolates intermediate or resistant to antimicrobial agents are also categorized as nonsusceptible to the agents. The rates of nonsusceptibility among major bacterial pathogens will be analyzed according to the different sites of infection and origin of the isolates. The associations between geographic area, hospital types from whom these isolates were obtained against the antimicrobial susceptibility will be analyzed.
