Objectives

In 2017, the World Health Organization (WHO) published a list of global priority pathogens (GPP)–12 species of bacteria with critical, high, and medium antibiotic resistance (AR). In this review, our goal was to quantify published reports of AR in this group of pathogens using the Medline-PubMed databases. We also sought to quantify, compare and rank the top five reported AR pathogens globally, regionally and for Bahrain, and describe the evidence from Bahrain for the purpose of infection prevention and control, and to help research and development.

Methods

We conducted a bibliometric, retrospective, descriptive review to search the Medline-PubMed database for reports specific to the WHO GPP list published up to 19 April 2017.

Results

Our search revealed 42 136 documents with an increase in the last five years. Globally, there were more high tier pathogen documents (33 640) than critical (6405) and medium (2091). Methicillin-resistant Staphylococcus aureus (MRSA) was the highest reported, followed by extended-spectrum beta-lactamases (ESBL) resistant Enterobacteriaceae and vancomycin-resistant Enterococcus faecium. Nine out of the 12 pathogens were gram-negative. MRSA was the topmost documented pathogen globally and in the Gulf Cooperation Council (GCC) region zone of classification, whereas ESBL resistant Enterobacteriaceae ranked the top in Bahrain. There were two critical tier pathogens in the global, GCC region, and Bahrain. We found 14 articles from Bahrain, four articles on ESBL resistant Enterobacteriaceae, three on MRSA, two on carbapenem-resistant Acinetobacter baumannii, and five on different pathogens.

Conclusions

Our findings suggest the need for a comprehensive, multipronged policy response particularly at the time when the antibiotic pipeline is nearly empty. We recommend thoughtful, integrated infection prevention and control strategies to address the immediate and long-term threats of AR in Bahrain and the GCC.
