Haem and xenosiderophore mediated iron acquisition by sinorhizobium meliloti and pseudomonas aeruginosa
… is capable of utilising several xenosiderophores and the haem compounds haemoglobin and haemin to overcome conditions of iron limitation. The high demand for iron in the nodule makes the study of S. meliloti 2011 biologically significant. Two putative hydroxamate siderophore outer membrane …

Biological activity and regulation of cyclic lipopeptide production in Pseudomonas corrugata and Pseudomonas mediterranea
Pseudomonas corrugata and P. mediterranea, are two closely related bacteria both causal agents of tomato pith necrosis and recently evaluated as biocontrol agents and producers of industrially-promising biomolecules. The interest of our work focused on cyclic lipopeptides (CLPs) that are surface …

Comparative biochemistry and genetic analysis of nucleoside hydrolase in Escherichia coli, Pseudomonas aeruginosa, and Pseudomonas fluorescens.
… of nucleosides into the free nucleic acid base and D-ribose. Nucleoside hydrolases have varying degrees of specificity towards purine and pyrimidine nucleosides. In E. coli, three genes were found that encode homologues of several known nucleoside hydrolases in protozoa. All three genes …

Investigating NLR-mediated immunity and Pseudomonas syringae effector interactions with two MACPF domain proteins in Arabidopsis thaliana.
… have evolved intracellular NUCLEOTIDE BINDING AND LEUCINE RICH REPEAT RECEPTORS (NLRs) that monitor the integrity of critical immune signaling components likely to be effector targets. NLR activation upregulates plant immune responses and triggers a form of localized cell death known as the …

Whole Genome Analysis of Escherichia coli and Pseudomonas aeruginosa Mixed Culture Biofilms Grown for 117 Days in Spaceflight
… tend to have an increased tolerance to physical and chemical stressors. They are capable of damaging water-associated infrastructure not only on Earth but on spacecraft in space as well. Biofilms can also act as a source of infections for crew members on spacecraft. In an unexpected event, an …

A Study of the Pyrimidine Biosynthesis Pathway and its Regulation in Two Distinct Organisms: Methanococcus jannaschii and Pseudomonas aeruginosa
… transcarbamoylase (ATCase) catalytic (PyrB) and regulatory (PyrI) polypeptides were found. Unlike Escherichia coli where the above genes are expressed from a biscistronic operon the two genes in M. jannaschii are separated by 200-kb stretch of genome. Previous researchers have not been able …

Evaluation of the antimicrobial activity of Plectranthus amboinicus leaf extracts on planktonic and biofilm forms of Staphylococcus aureus and Pseudomonas aeruginosa
… global concern of antimicrobial resistance (AMR) and the scarcity of antimicrobial drugs currently in development. Plectranthus amboinicus is known for its antimicrobial properties due to the phytochemical-rich essential oil contained within the glandular trichomes present on its leaves. The study …

Cloning and characterization of th BPR1 gene ('Botrytis cinerea and Pseudomonas syringae pv. phaseolicola susceptibility and Root length 1') from Arabidopsis thaliana
Analysis of a Pathogen and Circadian Clock controlled Arabidopsis gene, PCC1, revealed five paralogs in the genome of this model plant on chromosomes 1, 2 and 3. The expression pattern of these five members of the PCC1 super-family under various conditions and after particular stimuli was followed …

Presence and Role of Acanthamoeba in Wound Infections
… Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa are the main multi-drug resistant pathogens associated with deep wound infections which then may cause septicaemia. Treatment is problematic and re-infection is quite common. Free Living Amoebae (FLA), such as …

Effect of Standard Post-harvest Interventions on the Survival and Regrowth of Antibiotic-Resistant Bacteria on Fresh Produce
… bacteria is poorly understood. Antibiotics and antibiotic-resistant bacteria have been shown to persist in manure of animals administered antibiotics, and in compost generated from this manure, where there is the potential for their transfer to produce. The purpose of this study was to …

Influence of copper on resistance of Lumbricus terrestris to bacterial challenge
… Lumbricus terrestris, were challenged orally and intracoelomically with two bacterial species, Aeromonas hydrophila and Pseudomonas aeruginosa, and mortality rates were observed. Neither were found to be particularly pathogenic at injected doses of up to 108 bacteria per earthworm. The …

Bacteria isolated from coriander and other umbelliferous herbs
… associated with leaf spotting symptoms of coriander (Coriandrum sativum Linn.), anise (Pimpinella anisum) and caraway (Carum carvi), were tested for pathogenicity to coriander. Inoculation of young plants showed that 10 isolates caused dark, water soaked lesions on the leaves. The 13 isolates …

Polysulfone ultrafiltration membranes impregnated with silver nanoparticles show improved biofouling resistance and virus removal
Biofouling and virus penetration are two significant obstacles in water treatment membrane filtration. Biofouling reduces membrane permeability, increases energy costs, and decreases the lifetime of membranes. In order to effectively remove viruses, nanofiltration or reverse osmosis (both high …
