A first case of bacteremia and meningitis in a 5-week old child.

, previously known as , was initially isolated from powdered infant milk in 2010. It falls within the family (class: Enterobacterales). While was traditionally regarded as non-pathogenic, we now present a case of bacteraemia and meningitis in a 5-week-old child, successfully treated with cefotaxime.

Estimation of antimicrobial resistance of Belgium, 2022.

BackgroundAntimicrobial resistance (AMR) of (MG) is a growing concern worldwide and surveillance is needed. In Belgium, samples are sent to the National Reference Centre of Sexually Transmitted Infections (NRC-STI) on a voluntary basis and representative or robust national AMR data are lacking.AimWe aimed to estimate the occurrence of resistant MG in Belgium.

A first case of species catheter-related bloodstream infection.

We present a case of a 80-year-old patient with a catheter-related bloodstream infection caused by Chimaeribacter species. The Chimaeribacter genus represents a novel genus within the Yersiniaceae family. To the best of our knowledge, as of today, nothing is known about the pathogenicity of Chimaeribacter species, nor about the appropriate antimicrobial management.

Two Years of Genomic Surveillance in Belgium during the SARS-CoV-2 Pandemic to Attain Country-Wide Coverage and Monitor the Introduction and Spread of Emerging Variants.

An adequate SARS-CoV-2 genomic surveillance strategy has proven to be essential for countries to obtain a thorough understanding of the variants and lineages being imported and successfully established within their borders. During 2020, genomic surveillance in Belgium was not structurally implemented but performed by individual research laboratories that had to acquire the necessary funds themselves to perform this important task. At the start of 2021, a nationwide genomic surveillance consortium was established in Belgium to markedly increase the country's genomic sequencing efforts (both in terms of intensity and representativeness), to perform quality control among participating laboratories, and to enable coordination and collaboration of research projects and publications.

First case of isolation from a patient with a foot ulcer infection in Belgium.

We present the first documented isolation of from a patient in Belgium. The isolate was identified as using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing. Our methodology corresponds with the previous conclusions on the superior performance of MALDI-TOF MS for bacterial identification.

Nationwide Harmonization Effort for Semi-Quantitative Reporting of SARS-CoV-2 PCR Test Results in Belgium.

From early 2020, a high demand for SARS-CoV-2 tests was driven by several testing indications, including asymptomatic cases, resulting in the massive roll-out of PCR assays to combat the pandemic. Considering the dynamic of viral shedding during the course of infection, the demand to report cycle threshold (Ct) values rapidly emerged. As Ct values can be affected by a number of factors, we considered that harmonization of semi-quantitative PCR results across laboratories would avoid potential divergent interpretations, particularly in the absence of clinical or serological information.

Pyelonephritis and bacteremia caused by Haemophilus parainfluenzae: case-report of an unusual pathogen.

We present a case of a young man with known urinary tract abnormalities who developed pyelonephritis and bacteremia caused by Haemophilus parainfluenzae. Since routine urine culture usually does not include enriched media for Haemophilus spp., the true incidence of urinary tract infections caused by H.
