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.

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.

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.

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.

Predominance of rotavirus G9 genotype in children hospitalized for rotavirus gastroenteritis in Belgium during 1999-2003.

Background: Group A rotavirus genotypes G1, G2, G3 and G4 are the main etiological agents of infantile diarrhea. The G9 rotavirus has recently emerged as a fifth important genotype all over the world.

Objective: To characterize the VP7 gene of group A rotaviruses from gastroenteritis patients admitted to the Gasthuisberg University Hospital, Leuven, Belgium, during 1999-2003.

Human infection with a P[14], G3 lapine rotavirus.

Group A rotaviruses are the main cause of severe diarrhoea in humans and animals throughout the world. We report the first description of a clinically apparent infection with a P[14], G3 rotavirus (strain B4106) in a hospitalized 6-year-old child. The VP7 gene of the B4106 strain had the closest sequence similarity (94% and 97% on the nucleotide and amino acid level, respectively) with strain 30/96 (P[14], G3), a lapine rotavirus isolated in an Italian rabbit in 1996 while the VP4 gene had the closest similarity with strain 30/96 on the nucleotide level (96%), and with lapine strains C-11 (P[14], G3) and Alabama (P[14], G3), isolated in the United States in the 1980s on the amino acid level (99%).

Chromatography paper strip method for collection, transportation, and storage of rotavirus RNA in stool samples.

We developed a novel method that uses sodium dodecyl sulfate-EDTA-treated chromatography paper strips to collect unconcentrated fresh stool samples. After the paper strips were stored for 4 months at room temperature, rotavirus RNA could be successfully amplified by using reverse transcriptase PCR. The use of filter paper strips as a specimen support allows (self-)collection of stool samples by untrained persons.

Genetic characterization of a novel, naturally occurring recombinant human G6P[6] rotavirus.

A binary classification system has been established for group A rotaviruses, with the viral capsid protein VP7 defining G types and VP4 defining P types. At least 15 G types and 21 P types have been isolated globally with various G and P combinations. Most of the currently circulating human rotaviruses belong to G1P[8], G2P[4], G3P[8], and G4P[8].
