[Court-ordered therapy, the case of sex offenders in Belgium].

Following the Dutroux affair which rocked Belgium in 1996, the Belgian minister for justice signed cooperation agreements with the country's three regions (Flanders, Wallonia and Brussels-Capital), imposing on sex offenders therapy or treatment as an alternative to imprisonment. What legal programme is now in place for their management? Experience of the Brussels support centre.

Description of Acidovorax wautersii sp. nov. to accommodate clinical isolates and an environmental isolate, most closely related to Acidovorax avenae.

Three Gram-negative strains, NF 1078(T), NF 1598 and NF 1715, were isolated from clinical (two) and environmental (one) samples, respectively. Sequence analysis of the 16S rRNA genes revealed similarity of 100% among the three strains and next highest similarity to the type strain of Acidovorax avenae (98.16%).

Isolates belonging to CDC group II-i belong predominantly to Sphingobacterium mizutaii Yabuuchi et al. 1983: emended descriptions of S. mizutaii and of the genus Sphingobacterium.

Two clinical strains, NF 296 and NF 931, present in our collection, were identified biochemically as members of CDC group II-i. Determination of the 16S rRNA gene sequence revealed highest similarity with strains of Sphingobacterium mizutaii. Because these strains produced indole, whereas S.

Psychrobacter isolates of human origin, other than Psychrobacter phenylpyruvicus, are predominantly Psychrobacter faecalis and Psychrobacter pulmonis, with emended description of P. faecalis.

Human Psychrobacter isolates, other than Psychrobacter phenylpyruvicus, are predominantly designated Psychrobacter immobilis. Phenotypic and genotypic testing of Psychrobacter isolates that have been deposited in different culture collections as P. immobilis indicates that most of these human isolates belong to the species Psychrobacter faecalis and Psychrobacter pulmonis.

Description of Chryseobacterium anthropi sp. nov. to accommodate clinical isolates biochemically similar to Kaistella koreensis and Chryseobacterium haifense, proposal to reclassify Kaistella koreensis as Chryseobacterium koreense comb. nov. and emended description of the genus Chryseobacterium.

A collection of eight strains, NF 1366(T), NF 450, NF 1101, NF 1107, NF 1123, NF 1413, CCUG 15260 and CCUG 15624, from various clinical origins, were characterized biochemically as similar to Kaistella koreensis and Chryseobacterium haifense. They differed from K. koreensis, which is unable to alkalinize acetate, and from C.

Chryseobacterium hominis sp. nov., to accommodate clinical isolates biochemically similar to CDC groups II-h and II-c.

A collection of eight clinical strains from Belgian hospitals and three clinical strains of the CCUG collection were characterized biochemically as being similar to CDC groups II-h and II-c; the latter differs from group II-h only by positivity for sucrose acidification. These 11 strains were found to cluster according to 16S rRNA gene sequence similarity at a level of >or=99.5%, and on the basis of their tDNA-PCR profile.

Description of Wautersiella falsenii gen. nov., sp. nov., to accommodate clinical isolates phenotypically resembling members of the genera Chryseobacterium and Empedobacter.

A total of 26 isolates of non-fermenting, Gram-negative rods, obtained between 1980 and 2004 by various clinical laboratories in Belgium, with phenotypic characteristics resembling those of members of the genera Chryseobacterium and Empedobacter (indole-positive) and a biochemical profile resembling that of CDC group II-h, but urease-positive, were collected at the Université Catholique de Louvain Microbiology Laboratory, Belgium. The 16S rRNA gene sequences were determined for most of the isolates and showed 94-95 % similarity with the type strain of Empedobacter brevis as the closest relative, indicating that these isolates might belong to a separate genus. Furthermore, the 16S rRNA gene sequences of the isolates were similar, but two clusters (genomovars) could be distinguished.

Distribution of nocardia species in clinical samples and their routine rapid identification in the laboratory.

Eighty-six Nocardia strains isolated from clinical samples in Belgium were identified by 16S rRNA gene sequencing. Eighty-three (96%) strains belonged to only six Nocardia species: N. farcinica (38 [44%]), N.

Laboratory diagnosis of Clostridium difficile-associated diarrhoea: a plea for culture.

A routine protocol for diagnosing Clostridium difficile-associated diarrhoea (CDAD) based on both faecal-cytotoxin detection and toxigenic culture was adopted by the microbiology laboratory of the St Luc-UCL University Hospital in Brussels in 1997. A toxigenic culture is a faecal culture followed, in the case of positivity, by a direct immunoassay on colonies to detect toxin A production. The results obtained over the past 7 years in the hospital are reviewed here.

Histidine decarboxylase in Enterobacteriaceae revisited.

With a modification of Taylor's decarboxylation broth, histidine decarboxylase was detected in Enterobacter aerogenes, Morganella morganii, Raoultella ornithinolytica, and some strains of Citrobacter youngae and Raoultella planticola. This method provides a useful confirmatory test for identification of E. aerogenes strains.

Identification of a novel Brevibacterium species isolated from humans and description of Brevibacterium sanguinis sp. nov.

Six coryneforms isolated from blood and dialysate fluid were phenotypically similar to Brevibacterium casei, but 16S rRNA gene sequencing and DNA-DNA hybridization indicate that they belong to a new species for which the name Brevibacterium sanguinis is proposed.

Brevibacterium lutescens sp. nov., from human and environmental samples.

Three strains of coryneform rods isolated from clinical samples and one of environmental origin exhibited phenotypic and chemotaxonomic properties characteristic of the genus Brevibacterium and their 16S rRNA gene sequences were closely related (98.5-99.0 %) to that of Brevibacterium otitidis.

Bacteremia due to a novel Microbacterium species in a patient with leukemia and description of Microbacterium paraoxydans sp. nov.

A yellow-pigmented coryneform rod was isolated from the blood of a child with acute lymphoblastic leukemia who was perfused with a central venous catheter. The culture bottles were positive twice, at a 2-month interval. The isolate was identified as a Microbacterium sp.

Biochemical and susceptibility tests useful for identification of nonfermenting gram-negative rods.

Six hundred nineteen strains of nonfermenting gram-negative rods were tested for alkaline phosphatase, benzyl-arginine arylamidase, pyrrolidonyl arylamidase, ethylene glycol acidification, and susceptibility to desferrioxamine and colistin. The results were highly discriminant. Therefore, the proposed tests may be helpful for the identification of this group of organisms.
