Isolation of Mobiluncus in four cases of extragenital infections in adult women.

In four adult women with various clinical conditions, curved anaerobic bacilli, similar to organisms recently assigned to the new genus Mobiluncus, were isolated from extragenital sources. None of the patients presented symptoms or clinical abnormalities related to the genital tract. The clinical data of these cases are reported and the microbiological findings are briefly described.

Use of gas-liquid chromatography as a screening test for toxigenic Clostridium difficile in diarrhoeal stools.

In order to determine if gas-liquid chromatography (GLC) on concentrated stool extracts could be substituted to cell culture assay for cytotoxicity, we prospectively studied 154 diarrhoeal stools submitted for detection of Clostridium difficile toxin. Isocaproic-positive samples were cultured on egg yolk agar supplemented with cycloserine, cefoxitin and fructose for isolation of C difficile, and on egg yolk agar plus kanamycin for isolation of other clostridium species. Of the 154 samples, 129 were GLC-negative (height of the isocaproic peak less than 1.

[Gas-phase chromatography in the rapid bacteriological diagnosis of infections. Contributions and limitations of this technic].

Gas-liquid chromatography has been used directly on clinical specimens as a method for presumptive diagnosis of anaerobic infections. This technique proved to be valuable and reliable. Combined with a Gram stain, it offers the possibility to differentiate in less than 1 hour aerobic from anaerobic infections by means of detection of volatile fatty acids (short chain monocarboxylic acids) others than acetic acid.

Campylobacter jejuni peritonitis complicating continuous ambulatory peritoneal dialysis.

We report the occurrence of Campylobacter jejuni peritonitis complicating C. jejuni enteritis in a patient treated with continuous ambulatory peritoneal dialysis. Cure followed oral administration of erythromycin and intraperitoneal therapy with gentamicin.
