The genome of Pseudomonas aeruginosa consists of a relatively large circular chromosome (5.5–6.8 Mb) that carries between 5,500 and 6,000 open reading frames, and sometimes plasmids of various sizes depending on the strain. [11] Comparison of 389 genomes from different P. aeruginosa strains showed that just 17.5% is shared.
Pseudomonas aeruginosa is highly contagious and has displayed resistance to antibiotic treatments, making it difficult to manage effectively. Some strains of Pseudomonas are known to target white blood cells in various mammal species , posing risks to humans, cattle, sheep, and dogs alike.
Ecological micro-succession and the competition-colonization trade-off in a bacterial meta-community on-chip.(A) sketch of a micron-scale structured bacterial environment based on microfluidics technology; (B) Fluorescent microscopy image of Escherichia coli (magenta) and Pseudomonas aeruginosa (green) inhabiting a device of the type depicted in A and which has been wettened with growth media ...
Pseudomonas aeruginosa is an example of a mutualistic bacterium that can turn into a pathogen and cause disease: if it gains entry into the circulatory system it can result in infections in bone, joint, gastrointestinal, and respiratory systems.
Microscopic image of gram-negative Pseudomonas aeruginosa bacteria (pink-red rods). Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1]
Studies also suggest the emergence of antibiotic resistance in P. aeruginosa. [5] In 2000, the complete genome of a Pseudomonas species was sequenced; more recently, the genomes of other species have been sequenced, including P. aeruginosa PAO1 (2000), P. putida KT2440 (2002), P. fluorescens Pf-5 (2005), P. fluorescens PfO-1, and P. entomophila ...
Non-fermenters (also non-fermenting bacteria) are a taxonomically heterogeneous group of bacteria of the phylum Pseudomonadota that cannot catabolize glucose, and are thus unable to ferment.
D. tsuruhatensis can inhibit quorum sensing and biofilm formation, which could inform new therapeutic drugs against antibiotic-resistant bacteria. [9] D. tsuruhatensis inhibits quorum sensing and suppresses biofilm formation against Pseudomonas aeruginosa and other pathogens.
