Antimicrobial resistance surveillance of Bacteroides fragilis isolated from blood cultures, Europe, 2022 (ReSuBacfrag).

Objectives: Bacteroides fragilis is the most frequent cause of anaerobic bacteraemia. Although recent data suggest a rise in antimicrobial resistance (AMR) of this and other anaerobic bacteria, surveillance remains limited due to a lack of both data availability and comparability. However, a newly introduced standardised method for antimicrobial susceptibility testing (AST) of anaerobic bacteria has made larger scale surveillance possible for the first time.

Clostridium difficile infection.

Clostridium difficile infection (CDI) is the main cause of nosocomial diarrhea in industrialized countries and the source of a growing number of cases of diarrhea in the community. The outbreak of the hypervirulent strain belonging to ribotype 027 has increased the incidence and severity of CDI in some countries. Although CDI usually courses as a mild diarrhea it can lead to severe forms such as toxic megacolon or septic shock.

Epidemiology and risk factors for Clostridium difficile infection in critically ill patients in Spain: The PROCRID study.

Introduction: Our objectives were to describe the incidence, clinical characteristics, and risk factors for Clostridium difficile infection (CDI) in critically ill patients and to determine C. difficile PCR-ribotypes.

Methods: Prospective, observational study in 26 Spanish ICUs.

[Laboratory diagnosis of Clostridium difficile infection].

Clostridium difficile is the leading cause of nosocomial diarrhoea in developed countries, and is one of the main aetiologic agents of community diarrhea. The eruption of the hypervirulent strain BI/NAP1/027 has given rise to an increase in the morbidity and mortality of C.difficile infection (CDI).
