Pseudomonas aeruginosa is the most common gram-negative pathogen causing pneumonia in immunocompromised patients. Acute lung injury induced by bacterial exoproducts is associated with a poor outcome in P. aeruginosa pneumonia. The major pathogenic toxins among the exoproducts of P. aeruginosa and the mechanism by which they cause acute lung injury have been investigated: exoenzyme S and co-regu...
Extracellular vesicles (EVs) released by virtually every cell of all organisms are involved in processes of intercellular communication through the delivery of their functional mRNAs, proteins and bioactive lipids. We previously demonstrated that mouse embryonic stem cell-released EVs (mESEVs) are able to transfer their content to different target retinal cells, inducing morphological and bioch...
background: pseudomonas aeruginosa is considered an opportunistic pathogen; several reports indicate that the organism can also cause infections in healthy hosts. four effector proteins have been described in p. aeruginosa: exou, exos, exot, and exoy. these genes that are translated into protein products related to type iii secretion systems. materials and methods: a total of 134 samples were i...
Pseudomonas aeruginosa is an opportunistic pathogen that typically infects patients with a compromised immune defense. Here, we present the improved 6.5-Mb draft genome of strain WS136, an ExoS-positive and ExoU-negative highly cytotoxic chronic wound isolate recovered from pyoderma gangrenosum of a patient who received bone marrow transplantation.
The extracellular biofilm matrix includes primarily DNA and exopolysaccharides (EPS), which function to maintain aggregate structures and to protect biofilms from antibiotics and the immune response. Both polymers are anionic and have cation binding activity, however the impact of this activity on biofilms is not fully understood. Host cell contact is considered the primary signal for activatio...
Exosomes are small vesicles released by various cell types, including tumor cells, as a result of fusion of the multivesicular bodies with the plasma membrane. Exosomes can interact with target cells and mediate different processes, such as, tumor progression and intercellular transfer of proteins and RNA. Although heavily glycosylated forms of some proteins were found in exosomes, the role of ...
AIM Subclinical mastitis in bovines is mainly responsible for the huge economic loss of the dairy farmers, of which Pseudomonas aeruginosa is one of the causative agents. The study was aimed at a screening of suspected milk samples from different cattle farms of West Bengal for detection and confirmation of P. aeruginosa strains followed by their characterization. MATERIALS AND METHODS Around...
