[Biochemical characteristics of fungi isolated from ontocenoses of digestive tract in children].

Fermentation of carbohydrates and assimilation of carbon compounds were evaluated. The utilization of 18 specific carbon compounds was estimated in the investigation of each strains for differentiation of the species. From among 125 strains of fungi the following were found: Candida albicans (112 strain), C. famata (2), C. glabrata (1), C. guilliermondii (1), C. kefir (4), C. tropicalis (2). The activity of 19 hydrolases was investigated using API ZYM. Biotyping of Candida strains was done according to the Williamson classification (1986), modified by Kurnatowska (1998). All strains were isolated from the oral cavity, rectum, as well as from the materials collected during endoscopy in children.

[Fungal invasions in the digestive tract in children].

The aim of presented study were fungal invasions of the oral cavity and gastrointestinal (GI) tract in children suspected of the inflammation of gastric and duodenal mucosa and of absorption disturbance. The fungal strains (125) were identified using API 20C and API 20C AUX (bio Me'rieux); they were as follows: Candida albicans, C. famata, C. glabrata, C. guillermondii, C. kefyr and C. tropicalis.

[The sensitivity to ketoconazole of Candida strains isolated from the digestive tract ontocenoses in children].

The study included 52 children. During endoscopy the contents of oesophagus, stomach and duodenum were collected with catheters, and additionally washings from the oral cavity and anal swabs or samples of faeces. Materials were inoculated on Sabouraud's media. The axenic strains of fungi were identified using own methods and others tests (API 20C, API 20C AUX). The activity of ketoconazole (K) was measured against 100 strains of Candida: C. albicans (91 strains), C. kefyr (4), C. famata (2), C. tropicalis (1), C. guilliermondii (1), C. glabrata (1). The strains susceptibility to K (RO4 1400 Janssen) was estimated with the own system based on the dose-response curves; the minimal inhibitory concentration (MIC) values were canculated. The low values of MIC indicate high susceptibility to K of examined Candida strains.

Granulocyte colony-stimulating factor prophylaxis before operation protects against lethal consequences of postoperative peritonitis.

BACKGROUND: Postoperative peritonitis has a high mortality in human beings. It is accepted that cytokines are important mediators in pathophysiology of sepsis. The recent failure of clinical trials increased the necessity to proof new drugs in more clinically relevant animal models. The aim of this study was to examine the effect of granulocyte colony-stimulating factor (G-CSF) in addition to an antibiotic in postoperative peritonitis. METHODS: Dose-response curves and experimental conditions were developed in a total of 295 rats. The main experiment included three groups: control animals receiving a fecal inoculum, a group treated with antibiotic, and a third group receiving G-CSF in addition to the antibiotic. The main outcome was death, but in addition, serum tumor necrosis factor (TNF) level was determined. RESULTS: The mortality rate of 60% in antibiotic treated animals was considerably reduced by G-CSF to 20%. All animals of the control group died during the observation period of 120 hours. A correlation between TNF levels and mortality rate was observed. In G-CSF treated animals total suppression of TNF serum levels was accessible in contrast to the others. CONCLUSIONS: In a clinically relevant animal model G-CSF was effective as an additional concept of prophylaxis. These data are promising toward clinical trials.
