Background Invasive infections caused by Staphylococcus aureus have high clinical and epidemiological relevance. It is therefore important to monitor the S. aureus trends using suitable methods. Aim The study aimed to describe the trends of bloodstream infections (BSI) caused by meticillin-resistant S. aureus (MRSA) and meticillin-susceptible S. aureus (MSSA) in the European Union (EU) and the European Economic Area (EEA). Methods Annual data on S. aureus BSI from 2005 to 2018 were obtained from the European Antimicrobial Resistance Surveillance Network (EARS-Net). Trends of BSI were assessed at the EU/EEA level by adjusting for blood culture set rate (number of blood culture sets per 1,000 days of hospitalisation) and stratification by patient characteristics. Results Considering a fixed cohort of laboratories consistently reporting data over the entire study period, MRSA percentages among S. aureus BSI decreased from 30.2% in 2005 to 16.3% in 2018. Concurrently, the total number of BSI caused by S. aureus increased by 57%, MSSA BSI increased by 84% and MRSA BSI decreased by 31%. All these trends were statistically significant (p < 0.001). Conclusions The results indicate an increasing health burden of MSSA BSI in the EU/EEA despite a significant decrease in the MRSA percentage. These findings highlight the importance of monitoring antimicrobial resistance trends by assessing not only resistance percentages but also the incidence of infections. Further research is needed on the factors associated with the observed trends and on their attributable risk.

Point-prevalence antimicrobial surveillance programmes conducted by the Australian Group on Antimicrobial Resistance (AGAR) from 1986-1999 included consecutive clinical isolates of Staphylococcus aureus regardless of acquisition. Following a reported increase in community-acquired infections caused by methicillin-resistant S. aureus (MRSA) in the literature, AGAR performed the first survey of infections from outpatients, emergency department and general practitioner patients in 2000. Further community surveys were conducted in 2002, 2004 and 2006. In 2005 AGAR performed the first hospital-acquired infections survey (infections acquired more than 48 hours post admission) in part to track community MRSA clones emerging in the hospital setting. This article discusses the focus and main outcomes of the AGAR hospital and community surveys.

The World Health Organization has identified surveillance as a key objective in the containment of antimicrobial resistance. Local antimicrobial resistance surveillance data are used to generate antibiograms to monitor resistance patterns and inform clinicians in the selection of the appropriate empiric treatment when culture results are pending, or if laboratory diagnosis is unavailable. However, producing robust bacteriology data is challenging for Pacific Island Countries and Territories with limited microbiology laboratory capacity. The aim of this study is to describe pathogen occurrence and antibiotic resistance in specimens cultured at the main referral hospital in Vanuatu. We reviewed specimen culture results for the period from January 1, 2017 to December 31, 2019. Demographic and clinical data were extracted from printed and electronic registers and described and analysed. A total of 5816 specimens were cultured, of which 21% were culture positive. Staphylococcus aureus was the predominant pathogen overall (41%), and 3% of the isolates were the methicillin-resistant Staphylococcus aureus. Escherichia coli and Klebsiella pneumoniae were the most frequently isolated gram-negative pathogens, of which 14% and 26% were extended-spectrum β-lactamase-producing, respectively. Our results suggest there is a need for other Pacific Island Countries and Territories to conduct similar studies. There are gaps in knowledge about antimicrobial resistance in Pacific Island Countries and Territories. Antibiograms based on reliable data will define and inform local and national actions for containing antimicrobial resistance. There is also a need to establish a regional surveillance network to strengthen national efforts and to link surveillance data for collaborative action against antimicrobial resistance.

ABSTRACT The in vitro activities of ceftaroline and tedizolid were compared against Staphylococcus aureus, Enterococcus faecalis, and Enterococcus faecium clinical isolates collected from the China Antimicrobial Surveillance Network. Ceftaroline demonstrated potent activity against S. aureus isolates (MIC50/90, ≤0.25/1 mg/liter). Tedizolid was also highly active against S. aureus (MIC50/90, 0.25/0.5 mg/liter) and Enterococcus (MIC50/90, 0.5/0.5 mg/liter) isolates. Our results support the clinical usefulness of ceftaroline and tedizolid in treating Gram-positive infections.

Apropos to the article by Dr Bali, titled “Mupirocin resistance in clinical isolates of methicillin-sensitive and resistant Staphylococcus aureus in a tertiary care centre of North India” (1), the authors have raised important issue of emerging antimicrobial resistance (AMR). Antimicrobial resistance is an increasingly serious threat to global public health that requires action across all government sectors and society. As per WHO, AMR lurks the effective prevention and management of an ever-increasing spectrum of infections caused by bacteria, parasites, fungi and viruses. Novel resistance mechanisms are emerging and spreading globally, threatening the man’s ability to treat common infectious diseases.
