Kort om

I am a PhD candidate at the Inland Norway University of Applied Sciences. In my PhD research, I am working on the Rapid diagnosis of bacterial infections and antimicrobial resistance genes in blood samples (sepsis) using nanopore sequencing.

Due to the severity and mortality rate of the disease, rapid diagnosis of sepsis-causing bacteria is important. In sepsis patients, antibiotics should be prescribed as early as possible, preferably within one hour of the onset of symptoms. Unfortunately, the current diagnosis methods for sepsis are slow and time-consuming. Therefore, there is an urgent need to develop new methods that can rapidly and effectively diagnose sepsis. We are working on methods to reduce the time needed to diagnose sepsis.

Bloodstream infections (BSIs) and sepsis are major health problems, annually claiming millions of lives. Traditional blood culture techniques, employed to identify sepsis-causing pathogens and assess antibiotic susceptibility, usually take 2–4 days. Early and accurate antibiotic prescription is vital in sepsis to mitigate mortality and antibiotic resistance. This study aimed to reduce the wait time for sepsis diagnosis by employing shorter blood culture incubation times for BD BACTEC™ bottles using standard laboratory incubators, followed by real-time nanopore sequencing and data analysis. The method was tested on nine blood samples spiked with clinical isolates from the six most prevalent sepsis-causing pathogens. The results showed that pathogen identification was possible at as low as 102–104 CFU/mL, achieved after just 2 h of incubation and within 40 min of nanopore sequencing. Moreover, all the antimicrobial resistance genes were identified at 103–107 CFU/mL, achieved after incubation for 5 h and only 10 min to 3 h of sequencing. Therefore, the total turnaround time from sample collection to the information required for an informed decision on the right antibiotic treatment was between 7 and 9 h. These results hold significant promise for better clinical management of sepsis compared with current culture-based methods.
