The present study aims to investigate the antimicrobial and antitumor properties of Ganoderma lucidum fruit bodies grown under tropical habitat. The phytochemicals present in Ganoderma sp. DKR1 were analyzed and identified as saponins, tannins, terpenoids and phlobatannins. The bioactive compounds in Ganoderma sp. DKR1 were extracted using the solvents (ethyl acetate and chloroform). Its antimi...

Results In 2010 were identified 269 pathogens in 409 NI. The distribution including all sites of infection was: Coagulase Negative Staphylococcus (CNS) 20,6%, Pseudomonas aeruginosa 15,9%, Staphylococcus aureus 15,9%, Candida sp 7,8%, Escherichia coli 7,8%, Klebsiella sp 7,8%, Enterococcus sp 5,7%, Enterobacter sp 5,4%, Acinetobacter baumanii 3,4% and other agents 9,7%. The Staphylococcus sp se...

A plant growth promoting bacterial isolate (D5/23T) from the phyllosphere of winter wheat, able to fix atmospheric nitrogen and to produce auxines and cytokinins was investigated in a polyphasic taxonomy approach. Phylogenetic analyses using the 16S rRNA gene sequence of the strain clearly indicated that the strain belonged to the family Enterobacteriaceae, most closely related to Enterobacter ...

The taxonomy of Enterobacter species is rapidly changing. Herein we report a bloodstream infection isolate originally identified as Enterobacter cloacae by Vitek2 methodology that we found to be Kosakonia radicincitans using genetic means. Comparative whole genome sequencing of our isolate and other published Kosakonia genomes revealed these organisms lack the AmpC β-lactamase present on the ch...

Enterobacter sp. 638 is an endophytic plant growth promoting gamma-proteobacterium that was isolated from the stem of poplar (Populus trichocarpaxdeltoides cv. H11-11), a potentially important biofuel feed stock plant. The Enterobacter sp. 638 genome sequence reveals the presence of a 4,518,712 bp chromosome and a 157,749 bp plasmid (pENT638-1). Genome annotation and comparative genomics allowe...

Growth in sucrose medium was previously found to trigger the expression of functions involved in the plant associated life style of the endophytic bacterium Enterobacter sp. 638. Therefore, comparative transcriptome analysis between cultures grown in sucrose or lactate medium was used to gain insights in the expression levels of bacterial functions involved in the endophytic life style of strai...

Non-pigmented strains of Pseudomonas pyocyanea occur frequently and this organism has only limited activity in conventional biochemical tests; 50 strains were tested for the presence of arginine dihydrolase and found positive whereas only Salmonella sp. and Enterobacter sp. among other Gram-negative species were positive. The test for arginine dihydrolase is rapid and simple and suitable for ro...

Norfloxacin is a quinolinecarboxylic acid compound. We examined the in vitro activity of this compound against gram-positive and -negative species, including anaerobic species. It inhibited 90% (MIC90) of strains of Escherichia coli at 0.05 microgram/ml, Klebsiella sp. at 0.4 microgram/ml, Salmonella and Shigella spp. at 0.1 microgram/ml, Citrobacter sp. at 0.4 microgram/ml, Enterobacter cloaca...

Biofilm formation depends on several factors. The influence of different osmolarities on bacterial biofilm formation was studied. Two strains (Enterobacter sp. and Stenotrophomonas sp.) exhibited the most remarkable alterations. Biofilm formation is an important trait and its use has been associated to the protection of organisms against environmental stresses.
