An unusual overrepresentation of genetic factors related to iron homeostasis in the genome of the fluorescent Pseudomonas sp. ABC1 [PDF]
, 2021 Members of the genus Pseudomonas inhabit diverse environments, such as soil, water, plants and humans. The variability of habitats is reflected in the diversity of the structure and composition of their genomes. This cosmopolitan bacterial genus includes

Pyoverdine synthesis by the Mn(II)-oxidizing bacterium Pseudomonas putida GB-1
Frontiers in Microbiology, 2014 When iron-starved, the Mn(II)-oxidizing bacteria Pseudomonas putida strains GB-1 and MnB1 produce pyoverdines (PVDGB-1 and PVDMnB1), siderophores that both influence iron uptake and inhibit manganese(II) oxidation by these strains.

Antagonism between bacillus cereus and pseudomonas fluorescens in planktonic systems and in biofilms [PDF]
, 2008 In the environment, many microorganisms coexist in communities competing for resources, and they are often associated as biofilms. The investigation of bacterial ecology and interactions may help to improve understanding of the ability of biofilms to ...

The periplasmic transaminase PtaA of Pseudomonas fluorescens converts the glutamic acid residue at the pyoverdine fluorophore to -ketoglutaric acid [PDF]
, 2020 The periplasmic conversion of ferribactin to pyoverdine is essential for siderophore biogenesis in fluorescent pseudomonads, such as pathogenic Pseudomonas aeruginosa or plant growth-promoting Pseudomonas fluorescens.

Testing the evolutionary robustness of pyoverdine as a novel treatment against human opportunistic pathogens [PDF]
, 2021 Classical antibiotics are losing their efficacy as their application directly selects for resistance. Inducing indirect iron starvation appears to be an alternative and safer strategy as it underlies an extracellular working mechanism. Extracellular mode

Deep sequencing analyses expands the Pseudomonas aeruginosa AmpR regulon to include small RNA-mediated regulation of iron acquisition, heat shock and oxidative stress response [PDF]
, 2013 Pathogenicity of Pseudomonas aeruginosa, a major cause of many acute and chronic human infections, is determined by tightly regulated expression of multiple virulence factors.

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.ABSTRACT Trailing endpoints are a recognised challenge in broth microdilution MIC testing, particularly for bacteriostatic agents such as trimethoprim (TMP) and sulphonamides. In this study, we applied a pharmacodynamically guided refinement to determine the MIC of the combination against Staphylococcus pseudintermedius; we did not aim at redefining ...
