Case 318: Adult Polyglucosan Body Disease.

A 72-year-old man sought care for a cognitive deterioration over the past 5 years. There was a documented decline in his performance on the Mini-Mental State Examination (30 of 30 in 2016, 23 of 30 in 2021), with mainly episodic memory impairment. A more detailed history revealed a gait problem, paresthesia in both feet, and nocturnal urinary frequency.

Investigation of an outbreak of Campylobacter upsaliensis in day care centers in Brussels: analysis of relationships among isolates by phenotypic and genotypic typing methods.

An outbreak of Campylobacter upsaliensis in four Brussels day care centers (A, B-1, B-2, and C) affected 44 children. Diarrhea was the major symptom. From January 1991 to June 1992, the outbreak strain was isolated from 3, 1, and 21 (of 68) children in centers A, B-1, and B-2, respectively, and from 19 of 22 children in center C, IgG, IgM, and IgA antibodies were detected by Western blotting of serum specimens of 9 of 10 and 13 of 16 children in centers B-2 and C, respectively.

Polyphasic taxonomic study of the emended genus Arcobacter with Arcobacter butzleri comb. nov. and Arcobacter skirrowii sp. nov., an aerotolerant bacterium isolated from veterinary specimens.

The relationships of 77 aerotolerant Arcobacter strains that were originally identified as Campylobacter cryaerophila (now Arcobacter cryaerophilus [P. Vandamme, E. Falsen, R.

Characterization and description of "Campylobacter upsaliensis" isolated from human feces.

During a 3-year period, "Campylobacter upsaliensis" was isolated from 99 patients. Phenotypic characterization and numerical analysis of protein electrophoregrams showed evidence that "C. upsaliensis" is a distinct Campylobacter species with unique characteristics.

Semisolid blood-free selective-motility medium for the isolation of campylobacters from stool specimens.

Isolation of Campylobacter jejuni and C. coli from stool specimens is done by growing campylobacter colonies on solid selective media with or without blood. However, recognition of these colonies can be difficult.

Modified selective medium for isolation of Campylobacter spp. from feces: comparison with Preston medium, a blood-free medium, and a filtration system.

Our previously described (H. Goossens, M. De Boeck, and J.

Nosocomial outbreak of Campylobacter jejuni meningitis in newborn infants.

In a nosocomial outbreak of Campylobacter jejuni infection 11 newborn infants (7 female, 4 male) had meningitis. The outbreak was caused by a single strain of C jejuni, as demonstrated by biotyping (biotype I), serotyping (LAU 7/PEN 18 on heat-stable antigens, a new serotype on heat-labile antigens), and the identical susceptibility pattern and outer-membrane-protein profile on sodium dodecyl sulphate/polyacrylamide gel electrophoresis. Specific antibodies against the outbreak strain (enzyme-linked immunosorbent assay and Western blot) developed in all the babies.
