An ultrasonic treatment system, using a TiO 2 photocatalyst, was used to disinfect Legionella pneumophila. A kinetic study of the process indicates that TiO 2 significantly improves the disinfection process. The
Legionella pneumophila is the second most common cause of severe community-acquired pneumonia requiring treatment with intermittent positive pressure ventilation. The prognosis of this condition and its complications have not been well documented. Erythromycin is the first-line antibiotic of choice based on...
L. pneumophila is commonly found in natural water systems, soils, and engineered structures using water. Cooling towers, air conditioning systems, water systems, humidifiers, and whirlpool DISEASE FACTS: Pneumonia is the predominant clinical manifestation of L. pneumophila infection, and treatment is ...
Legionellaspecies are environmental Gram-negative γ-proteobacteria that parasitize and replicate within free-living unicellular eukaryotes1,2.Legionella pneumophila(Lp) is the leading cause of a lower respiratory infection known as legionellosis that produces an atypical pneumonia with a significant disease...
pneumophila , evolution of L. pneumophila , and its pathogenesis. It also covers clinical features, diagnosis, treatment, and prevention and control of Legionnaires' disease. L. pneumophila possesses a remarkable ability to manipulate various host cell processes to form a protective, membrane-bound ...
Several studies have attempted to determine the treatment of choice for L. pneumophila ; however, no current algorithm exists. Prevention of LD is aimed at proper maintenance of building cooling towers, plumbing design, and construction, in addition to chemoprophylaxis in a subgroup of ...
The causative agent was identified as an aerobic gramnegative bacterium, subsequently namedLegionella pneumophila.1Although the family Legionellaceae comprises more than 40 species,L. pneumophilaremains the most common species implicated in human disease and therefore will be the focus of this discussion...
Related to Legionella pneumophila:Legionnaires disease,Legionella pneumonia,Mycoplasma pneumoniae legionella (ˌliːdʒəˈnɛlə) n,pl-lae(-ˌliː) (Microbiology) any Gram-negative rod-shaped bacterium of the genusLegionella,includingL. pneumophila,which causes legionnaire's disease ...
Within these biofilms, Legionella pneumophila is a primary pathogen, leading to these environments serving as sources for disease outbreaks. Here we show a reduction in biofilm bio-volume upon treatment with citrate-coated 6-nm platinum NPs, polyethylene glycol (PEG)-coated 11-nm gold NPs, and ...
steroids may also result in an increased susceptibility to infections, especially by an opportunistic bacterium such asL. pneumophila.Although the spectrum of microbes causing infections in patients during steroid therapy is not completely clear, experimental animal studies showed that steroid treatment i...
