Adaptation to microaerobic or anaerobic environments is essential for certain lifestyles of P. aeruginosa, for example, during lung infection in cystic fibrosis and primary ciliary dyskinesia, where thick layers of lung mucus and bacterially-produced alginate surrounding mucoid bacterial cells can limit the diffusion of oxygen.
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
The lung microbiota is the pulmonary microbial community consisting of a complex variety of microorganisms found in the lower respiratory tract particularly on the mucous layer and the epithelial surfaces. These microorganisms include bacteria, fungi, viruses and bacteriophages. The bacterial part of the microbiota has been more closely studied.
On a basic level, "pseudomonas is a genus of bacteria that is widespread in the environment and is a cause of various infections, ... lungs (such as pneumonia) or other parts of the body. "Some of ...
Stenotrophomonas maltophilia is an aerobic, nonfermentative, Gram-negative bacterium.It is an uncommon bacterium and human infection is difficult to treat. [1] Initially classified as Bacterium bookeri, [2] then renamed Pseudomonas maltophilia, S. maltophilia was also grouped in the genus Xanthomonas before eventually becoming the type species of the genus Stenotrophomonas in 1993.
Pyocyanin (PCN −) is one of the many toxic compounds produced and secreted by the Gram negative bacterium Pseudomonas aeruginosa.Pyocyanin is a blue secondary metabolite, turning red below pH 4.9, with the ability to oxidise and reduce other molecules [2] and therefore kill microbes competing against P. aeruginosa as well as mammalian cells of the lungs which P. aeruginosa has infected ...
Gram-negative bacteria are seen less frequently: Haemophilus influenzae , Klebsiella pneumoniae , Escherichia coli , Pseudomonas aeruginosa , Bordetella pertussis, and Moraxella catarrhalis are the most common. These bacteria often live in the gut and enter the lungs when contents of the gut (such as vomit or faeces) are inhaled.
Aspiration pneumonia is a type of lung infection that is due to a relatively large amount of material from the stomach or mouth entering the lungs. [1] Signs and symptoms often include fever and cough of relatively rapid onset. [1]
