ABSTRACT
Objective:
To determine the in vitro activity of ceftobiprole against resistant bacteria commonly causing infections in hospitalized patients at Siriraj Hospital.Methods:
The studied organisms were MRSA (32 isolates), Enterococcus sp. (30 isolates), ESBL-producing E.coli (20 isolates), ESBL-producing K.pneumoniae (20 isolates), MDR P.aeruginosa (30 isolates) and MDR A.baumannii (30 isolates). The susceptibility of ceftobiprole was determined by the disk diffusion test for all 162 isolates and the MIC was determined by the E-test method for 5 isolates of each organism.Results:
All isolates of MRSA and 77% of Enterococcus sp. isolates were susceptible to ceftobiprole. All isolates of ESBL-producing E.coli and MDR A.baumannii were not susceptible to ceftobiprole. Only 10% to 20% of ESBL-producing K.pneumoniae and P.aeruginosa were susceptible to ceftobiprole. The MICs of ceftobiprole against all tested organisms were correlated with the inhibition zone diameters.Conclusion:
Ceftobiprole is very active against MRSA and is moderately active against Enterococcus sp. Ceftobiprole is considered inactive or less active against ESBL-producing gram negatives, MDR P.aeruginosa and MDR A.baumannii.
