Escherichia coli
Escherichia coli (E. coli) is s a gram-negative, rod-shaped bacterium that naturally resides in the intestines of humans and warm-blooded animals. While most strains of E. coli are harmless and play an important role in the gut microbiome, some strains, such as Shiga toxin-producing E. coli (STEC), can cause severe foodborne illness.
Escherichia coli facts in Norway
Norway, like many countries, experiences sporadic cases of E. coli infections, particularly those caused by pathogenic strains like STEC. These infections are often linked to contaminated food, water, or contact with animals.
Outbreak Overview
Norway has experienced significant outbreaks of Escherichia coli in recent years, particularly involving strains like O26:H11. A major outbreak in 2023 led to at least 24 confirmed cases, primarily in young children.
Surveillance
The Norwegian Institute of Public Health (Folkehelseinstituttet) maintains an active surveillance system to detect and respond to E. coli outbreaks. Cases are reported and investigated to identify sources and prevent further spread.
Antimicrobial Resistance (AMR)
There is increasing concern about antimicrobial-resistant E. coli strains globally, and Norway is actively monitoring and addressing this issue through its NORM-VET program, which assesses AMR in humans and animals.
Escherichia coli spread in Europe
A recent study (vg.no) by the European Centre for Disease Prevention and Control (ECDC) has highlighted the rapid spread of the antibiotic-resistant E. coli strainST131 across Europe. This strain is particularly concerning due to its resistance to carbapenem antibiotics, which are often considered a last-resort treatment for bacterial infections. The strain has been detected in healthcare and community settings, with genomic studies showing its presence in multiple countries, including Norway, Germany, and France. Enhanced monitoring and stricter antibiotic stewardship programs have been recommended to contain its spread.
