EARS-Net data on Antimicrobial Resistance in Ireland, Q1-3 2016 KEY POINTS, 2016 (General) Escherichia coli The numbers of invasive E. coli infections have increased since 2004 The proportion of ESBL-positive E. coli increased in 2016* Staphylococcus aureus/ MRSA The number and proportion of MRSA bloodstream infections have decreased since 2006; however, in contrast to this, the rate of MSSA BSIs is increasing Klebsiella pneumoniae ESBL-positivity and resistance to fluoroquinolones and aminoglycosides increased dramatically between 2012 and 2013 corresponding with the rise of multi-drug resistant K. pneumoniae (MDRKP): the proportion of MDRKP among invasive K. pneumoniae infections decreased in 2016* Carbapenem-resistance, particularly as a result of carbapenemase production, among K. pneumoniae decreased in 2016*, but in recent years the trend has been increasing Enterococcus faecium/ VREfm (vancomycin-resistant E. faecium) Ireland has had the highest proportion of VREfm in Europe since 2008 Pseudomonas aeruginosa The proportion of multi-drug resistant P. aeruginosa has increased in 2016* * 2016 data provisional to the end of Q3 only EARS-Net data on Antimicrobial Resistance in Ireland, Q1-3 2016

EARS-Net data on Antimicrobial Resistance in Ireland, Q1-3 2016 KEY POINTS, 2016* (1) Escherichia coli The numbers of invasive E. coli infections have increased since 2004 (note: the decrease in 2015 was due to incomplete reporting by 3 laboratories) The proportion of patients with invasive infections caused by E. coli producing extended-spectrum beta-lactamases (ESBLs) increased to 11.1%, the highest proportion to date The proportion of invasive infections caused by multi-drug resistant (MDR) E. coli (displaying resistance to three or more antimicrobial classes) decreased to 14.0% Staphylococcus aureus/ MRSA The proportion of S. aureus bloodstream infections (BSIs) that were meticillin-resistant (MRSA) decreased to14.7%, the lowest proportion to date In contrast to this, the rate of meticillin-susceptible S. aureus (MSSA) BSIs is increasing Klebsiella pneumoniae The proportion of patients with invasive infections caused by multi-drug resistant K. pneumoniae (MDRKP) decreased to 7.4% The proportion of patients with invasive infections caused by carbapenem-resistant K. pneumoniae isolates decreased to 1.2%, but in recent years the overall trend has been increasing *2016 data provisional to the end of Q3 only EARS-Net data on Antimicrobial Resistance in Ireland, Q1-3 2016
