Monitoring Biofilm Formation and Microbial Interactions that May Occur During a Contamination Incident across the Network of a Water Bottling Plant.

The present study aims to monitor the ability of to colonize and compete as a member of the mixed species biofilm within key points at a water bottling plant, in case of a contamination incident with this major foodborne pathogen. To achieve this goal, bacterial communities throughout the production line were collected and their identities were investigated by microbial counts and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). These bacterial communities alone or along with constructed serovar Typhimurium (ST) fluorescence-based bioreporters were left to form a biofilm on stainless steel for 6 days at 20 °C.

A novel symbiovar (aegeanense) of the genus Ensifer nodulates Vigna unguiculata.

Background: Cowpea (Vigna unguiculata) forms nitrogen-fixing root nodules with diverse symbiotic bacteria, mainly slow-growing rhizobial species belonging to the genus Bradyrhizobium, although a few studies have reported the isolation of fast-growing rhizobia under laboratory and field conditions. Although much research has been done on cowpea-nodulating bacteria in various countries around the world, very limited information is available on cowpea rhizobia in European soils. The aim of this study was to study the genetic and phenotypic diversity of indigenous cowpea-nodulating rhizobia in Greece.

Phylogenetic multilocus sequence analysis of indigenous slow-growing rhizobia nodulating cowpea (Vigna unguiculata L.) in Greece.

Cowpea (Vigna unguiculata) is a promiscuous grain legume, capable of establishing efficient symbiosis with diverse symbiotic bacteria, mainly slow-growing rhizobial species belonging to the genus Bradyrhizobium. Although much research has been done on cowpea-nodulating bacteria in various countries around the world, little is known about the genetic and symbiotic diversity of indigenous cowpea rhizobia in European soils. In the present study, the genetic and symbiotic diversity of indigenous rhizobia isolated from field-grown cowpea nodules in three geographically different Greek regions were studied.

The effect of synbiotics on acute radiation-induced diarrhea and its association with mucosal inflammatory and adaptive responses in rats.

Background: Previous clinical studies advocated that probiotics beneficially affect acute radiation-induced diarrhea. These encouraging results were attributed to the restoration of the intestinal flora; however, there is lack of evidence if and how probiotics influence the underlying pathophysiological mechanisms.

Aims: The present study was conducted to investigate the potential supporting role of a synbiotic preparation (combination of pro- and pre-biotics) on experimentally-induced acute radiation diarrhea from the perspective of mucosal inflammation and histological injury.

Surgical treatment of a giant mesenteric fibromatosis mimicking a gastrointestinal stromal tumor: a case report and current treatment aspects.

Intra-abdominal fibromatosis (IAF), usually located at the mesenteric level, is a locally invasive tumor of fibrous origin. Although lacking the ability to metastasize, it has the tendency to recur. The case described here is a case of mesenteric fibromatosis with involvement of the bowel wall, which had the appearance of a gastrointestinal stromal tumor (GIST), a tumor with malignant behavior.
