The opportunistic pathogen Pseudomonas aeruginosa causes infections that are difficult to treat by antibiotic therapy. This bacterium can cause biofilm infections where it shows tolerance to antibiotics. Here we report the novel use of a metallo-complex, desferrioxamine-gallium (DFO-Ga) that targets P. aeruginosa iron metabolism. This complex kills free-living bacteria and blocks biofilm format...

The compounds benzyloxycarbonyl-L-leucyl-hydroxamate (Z-Leu-NHOH), phosphoryl-L-leucyl-L-phenylalanine (P-Leu-Phe) and 2-mercaptoacetyl-L-phenylalanyl-L-leucine (HSAc-Phe-Leu) strongly inhibit the activity of Pseudomonas elastase in vitro. The capacity of these inhibitors to prevent corneal melting and perforation due to the elastase was examined in rabbit eyes by intrastromal injections of ela...

There is a lack of studies on the root-associated bacterial microbiome cassava plants. The identification and characterization rhizobacteria can contribute to understanding adaptation agriculturally important crop plants abiotic stress. Rhizobacteria play significant role in plants, as they alleviate drought stress by various mechanisms that enhance plant growth under these stressor conditions....

Salinity is a type of abiotic stress that negatively affects plant growth and development. Textile hemp (Cannabis sativa L.) an important multi-purpose crop shows sensitivity to salt in genotype- developmental stage-dependent manner. The root shoot biomasses decrease the presence NaCl during vegetative several stress-responsive genes are activated. Finding environmentally friendly ways increase...

Glutaminase (EC.3.5.1.2), it is found in many in many eukaryotic and prokaryotic cell, glutaminase can be used in food industries as flavor enhancer, pseudomonas fluorescens and vibiro casticola may be added to some kinds of food to give a popular flavor [1]. Glutaminase is used in oral dehydration solution since it transforms glutamine which helps in absorption of ions in small intestine [2]. ...

The in vitro susceptibilities of three Pseudomonas species (Pseudomonas aeruginosa, Pseudomonas putida, and Pseudomonas fluorescens) and Xanthomonas maltophilia to quinolone antimicrobial agents were determined. Several newer agents, particularly PD117558, PD117596, PD127391, sparfloxacin (AT-4140), A-56620, and temafloxacin, were active against Pseudomonas species. X. maltophilia isolates were...

The complete genome of the Pseudomonas aeruginosa bacteriophage PM105 is 39,593 bp long. The phage belongs to the B3 family of transposable Mu-like phages, as confirmed by the presence of bacterial DNA joined to the phage genome ends. PM105, together with other B3-like phages, form a newly arising species.

Fourteen quinolone-resistant Pseudomonas putida isolates were recovered from imported frozen shrimp sold in the United States. Two isolates harbored plasmids with qnrA and qnrB genes. PCR and DNA sequencing of quinolone resistance-determining regions identified novel substitutions in GyrA (His139→Glu and Thr128→Ala) and GyrB (Thr442→Asn, Gly470→Ala, and Ile487→Pro) and previously reported subst...

Here, we report the complete genome sequence for an isolate of Pseudomonas stutzeri that is highly competent for natural transformation. This sequence enables insights into the genetic basis of natural transformation rate variations and provides an additional data point for genomic comparisons across a ubiquitous and highly diverse bacterial species.
