Colonization by Clostridioides difficile is common in children with inflammatory bowel disease (IBD) and complicates both the management of IBD and the diagnosis of C. difficile infection (CDI). There is a paucity of data on rates, risk factors, and outcomes associated with asymptomatic C. difficile colonization in children with IBD. We enrolled and prospectively followed 87 children with IBD without acute gastrointestinal symptoms. Twelve patients (13.8%) tested positive for C. difficile and were considered to have asymptomatic colonization. Elevated white blood cell count was associated with C. difficile colonization based on univariate regression. Three of the 12 (25%) C. difficile colonized patients were diagnosed with CDI in the 90 days following screening for C. difficile, versus 0 of the 75 who tested negative for C. difficile (p = 0.002). This data set the stage for further longitudinal tracking of children with IBD for C. difficile colonization and associated outcomes.

Clostridioides difficile infection (CDI) remains a significant cause of infectious colitis in the United States. Susceptibility to CDI is associated with perturbation of the gut microbiota, the indigenous microbes in the gastrointestinal tract. Upon colonization, the production of toxins and the ability to produce spores for environmental dissemination contribute to C difficile pathogenicity.

This article offers a clinically focused overview of Clostridioides difficile infection (CDI) diagnosis, emphasizing the need to test only symptomatic patients and to distinguish true infection from colonization. It reviews multistep diagnostic algorithms that pair glutamate dehydrogenase (GDH) testing or nucleic acid amplification tests (NAAT) with toxin assays to improve accuracy. The limitations of PCR-only approaches are discussed, with a strong emphasis on clinical correlation.

Recurrent infection (rCDI) remains a significant global health challenge, characterized by high morbidity, substantial healthcare costs, and an increased risk of severe complications. , a gram-positive, spore-forming bacterium, is the primary cause of healthcare-associated diarrhea. The pathogenesis of rCDI is closely tied to gut microbiota disruptions, often triggered by antibiotic use, immunosuppression, and prolonged hospital stays.

Purpose: This study was undertaken to know the epidemiology of various microorganisms causing gastroenteritis in paediatric age group, to evaluate clinico-microbiological correlation with respect to the type of microorganism, to study the clinical presentations and impact of syndromic based film array assay on antimicrobial stewardship and patient management.
Methods: This is five years retrospective study in which the results of Gastrointestinal film array panel of stool specimens of children <=16 Years of age who presented with gastroenteritis during 2019 to 2023 were noted. Clinical correlation of the microbes was done with respect to suspected clinical diagnosis, age, immune status and other underlying illness.

Background: Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) continue to contribute to excess morbidity and mortality among Canadians.
Objective: This report describes epidemiologic and laboratory characteristics and trends of HAIs and AMR, 2019-2023, using surveillance and laboratory data submitted by hospitals to the Canadian Nosocomial Infection Surveillance Program (CNISP) and by provincial and territorial laboratories to the National Microbiology Laboratory.
Methods: Data was collected from 109 Canadian sentinel acute care hospitals between January 1, 2019 and December 31, 2023, for infections (CDI), methicillin-resistant (MRSA) bloodstream infections (BSIs), vancomycin-resistant (VRE) BSIs (specifically and ), carbapenemase-producing (CPE) and carbapenemase-producing (CPA) infections and colonizations and ().
