AI Article Synopsis
- * Out of 29,222 isolates, 62% were Gram-negative bacteria, with a notable increase in extended spectrum beta lactamase (ESBL) production and the identification of 733 carbapenem-resistant isolates, raising concerns about rising multidrug resistance (MDR).
- * The findings suggest an urgent need for enhanced resources and strategies to monitor and manage MDR organisms in Fiji, particularly due to the rapid spread of resistant bacteria in a major hospital setting.
Article Abstract
Background: There is a paucity of data on antimicrobial resistance in Fiji. The aim of this study was to determine the antimicrobial susceptibility profile of bacterial isolates from clinical samples at Colonial War Memorial Hospital in Fiji.
Methods: This retrospective study reviewed four-year of data from January 1, 2019, through December 31, 2022. Laboratory testing was carried out using locally approved protocols. Selective antimicrobial susceptibility testing was performed whereby only isolates resistant to first line antimicrobials were tested against second line antimicrobials. Only the first isolate of a given species per patient in a single year were included in the analysis. WHONET software and Microsoft Excel were used for analysis.
Findings: A total of 29,222 bacterial isolates were included, 62% (n = 18,084) were Gram-negative bacteria. was the most common (n = 5363), followed by (n = 4321). Extended spectrum beta lactamase (ESBL) production increased from 30% in 2019 to 43% in 2022 amongst , and 10%-23% . There were 733 carbapenem-resistant isolates identified from clinical samples, 61% (n = 445) were . , 15% (n = 110) and 14% (n = 101) . Amongst the isolates tested, susceptibility to meropenem declined from 99% (272/274) in 2019 to 79% (255/325) in 2022. The rate of methicillin resistance amongst was steady, remaining between 11% and 13%.
Interpretation: This study demonstrated a high rate of MDR amongst Gram-negative bacteria, especially ESBL producing and carbapenem-resistant . The emergence and rapid spread of carbapenemase producing in Fiji's largest hospital is of particular concern. There is an urgent need to allocate resources to improve existing capacity and to develop effective multimodal strategies to detect, manage and control the spread of MDR organisms.
Funding: This study was supported by the Medical Research Future Fund through the Australian government (grant number APP 1200970).

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Colibacillosis is a disease caused by avian pathogenic Escherichia coli (APEC) isolates which results in significant morbidity and mortality in poultry, as well as in economic loses. In order to identify APEC strains in a population of 898 E. coli isolates from poultry samples collected from different avian flocks located in the Valencian Region, Spain, we analysed the most significantly related to highly-pathogenic colibacillosis virulence-associated genes (VAGs) (hlyF, iroN, iss, iutA and ompT) by multiplex real-time polymerase chain reaction (RT-PCR).
