Table KWH-1. Antibiogram for common bacterial isolates, Kwong Wah Hospital, 2015
Indicate ≥ 10% reduction in resistance rate compared to 2014
Indicate ≥ 10% increase in resistance rate compared to 2014
Indicate ≥ 10% increase in resistance rate compared to 2014
- Organisms isolates from blood, urine and respiratory specimens. Interpreted according to CLSL.
- Cefoxitin was used to detect methicillin-resistant Staphylococci.
- Susceptibility not performed on urine isolates.
- Test performed on urine isolates only.
- Overall prevalence of extended-spectrum β-lactamases (ESBL) were 28% for E.coli, 11% for Klebsiella species. ESBL-producing strains should be interpreted as resistant to all penicillins, cephalosporins and aztreonam.
- % of MRSA among Staphylococcus aureus isolated from blood, urine and respiratory specimens: 61% in non-ICU & -HDU and 45% in ICU & HDU.
- The 181 strains of Streptococcus pneumoniae were from respiratory specimens. In addition, there were 6 invasive isolates of Streptococcus pneumoniae in blood; % Penicillin resistant: meningitis breakpoint at MIC ≥ 0.12 = 0%. In Streptococcus pneumoniae, resistance to azithromycin & clarithromycin can be predicted by testing erythromycin (CLSI M100-S25).
- Except Streptococcus agalactiae (group B) and Streptococcus pneumoniae.
- Include Adult ICU and Neurosurgical HDU.
- Overall prevalance of extended-spectrum β-lactamases (ESBL) were 41% for E.coli, 14% for Klebsiella species. ESBL-producing strains should be interpreted as resistant to all penicillins, cephalosporins and aztreonam.
