Legionella pneumophila

Referansefunksjon. Folkehelseinstituttet (FHI) har referansefunksjon for Legionella pneumophila for å bidra til nasjonal epidemiologisk overvåking og utbruddsetterforskning.Videre mottar FHI stammer fra miljøprøver ved utbruddsetterforskning. Referansefunksjonen er delt med Helse Vest RHF ved Sjukehuset Stavanger HF Legionella pneumophila kan deles inn i 19 serogrupper, hvorav serogruppe 1, serogruppe 4 og 6 er de mest vanlige som årsak til utbrudd av legionellose. Andre arter er ofte gitt navn etter stedet de ble funnet, f.eks. L. longbeachae og L. parisiensis L. pneumophila. Legionella pneumophila er en bakterie med særlige krav til vekstforhold, og den finnes vidt distribuert i naturlige vannkilder med høyeste forekomst sommer og høst. I naturen vil den finnes i biofilmer i stillestående vann med næringsstoffer fra alger, amøber og andre døde bakterier. Den er ofte en intracellulær parasitt i amøber Legionella er en slekt av gramnegative bakterier som kan forårsake legionærsykdom, en form for lungebetennelse og Pontiac-feber, en mindre alvorlig tilstand uten lungebetennelse, men med influensalignende symptomer. Legionella pneumophila opptrer med mange ulike serotyper (immunologiske grupper), og det finnes mange beslektede arter. Av disse er det flere som er årsak til sykdom Legionella pneumophila ble påvist i vannsystemet på ca. 50 % av Sjøforsvarets fartøyer. En og samme genotype ble funnet i tre fartøyer. Genotyper funnet på to av fartøyene ble også funnet i vannfyllingsstasjonen som fartøyene hadde benyttet. Frittlevende amøber syntes å være en premiss for vekst av L. pneumophila i vannsysteme

Epidemiology. Legionella pneumonia tends to be more prevalent among immunocompromised patients. Legionella pneumophila is found in ~15% (range 2-25%) of adults hospitalized for pneumonia 5. Clinical presentation. Apart from the respiratory and inflammatory related symptoms, hyponatremia is a recognized feature due to inappropriate ADH secretion.. The bacterium Legionella pneumophila is responsible for most cases of Legionnaires' disease. Outdoors, legionella bacteria survive in soil and water, but rarely cause infections. However, legionella bacteria can multiply in water systems made by humans, such as air conditioners

Legionella pneumophila er ein bakterie av slekta Legionella, som kan forårsaka den dødelege sjukdommen med det same namnet, også kalla legionærsjuke, hjå menneske. Denne biologiartikkelen er ei spire. Du kan hjelpe Nynorsk Wikipedia gjennom å Denne sida. Legionella pneumophila is a Gram-negative bacillary bacterium.It lives in stagnant water at high temperatures and its growth is favoured by the presence of organic matter. Requires oxygen to breathe and has a flagellum to move. 16 serogroups of L. pneumophila have been identified. From the 30 known Legionella species, Legionella pneumophila serogroup 1 is responsible for most human infections Legionella has a bad reputation because of its pathogenicity, although complete recovery from Legionnaire's is probable upon proper diagnosis. Genome Structure. Research on the Legionella genome structure is underway. Legionella pneumophila subsp. pneumophila str. Philadelphia 1 was completed in 2001 Legionella is a genus of pathogenic Gram-negative bacteria that includes the species L. pneumophila, causing legionellosis (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever.. Legionella may be visualized with a silver stain or cultured in cysteine-containing media such as buffered charcoal yeast.

Morphology of Legionella pneumophila: Legionellae are thin, non-capsulated bacilli, 25 µm x 0.3­-1 µm, coccobacillary in clinical material and assum­ing longer forms in culture. Most are motile with polar or subpolar flagella. They are gram-negative but stain poorly, particularly in smears from clinical specimens Legionellainfeksjon er infeksjon med bakterien Legionella pneumophila. Bakterien er årsak til legionærsykdom og til Pontiac-feber, som er en mindre alvorlig sykdomstilstand uten lungebetennelse (pneumoni).

Legionella was first recognized in 1976 after an outbreak of pneumonia at an American Legion convention in Philadelphia.. Mode of Transmission: Legionella pneumophila has only been found in aquatic systems preferably warm. Legionella pneumophila is the bacteria responsible for Legionnaires' Disease, a pneumonia that can infect humans through the inhalation of bacteria-laden water vapor. It has a 9% fatality rate. While Legionella exists naturally in the environment where it poses little risk, in built environments, its population can thrive and get amplified in warm and stagnant conditions, and in some.

After Legionella grows and multiplies in a building water system, water containing Legionella then has to spread in droplets small enough for people to breathe in. People can get Legionnaires' disease or Pontiac fever when they breathe in small droplets of water in the air that contain the bacteria LegioTag, Legionella pneumophila specific label is a 6-Azido-2,4-diacetamido-2,4,6-trideoxy-D-mannose (Man 2 NAc 4 NAc 6 N 3) analogue of the natural 2,4-diacetamido-2,4,6-trideoxy-D-mannose which contains an azido moiety, for species-specific detection and labeling of Legionella pneumophila Legionella are gram-negative, aerobic, unencapsulated bacilli that are nutritionally fastidious requiring special media for growth.The family Legionellaceae comprises more than 49 species with more than 64 serogroups.

The qualitative immunoenzymatic determination of specific antibodies is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique This study implemented the Legiolert test (a culture‐based assay for L. pneumophila based on the most probable number [MPN]) at 12 utilities to assess their experiences and to develop a baseline of Legionella pneumophila occurrence in drinking water distribution systems. A total of 679 samples were analyzed during the study: 53 source water, 50 from the plant effluent, and 576 from the.

Legionella pneumophila is the most common cause of the severe respiratory infection known as Legionnaires' disease. L. pneumophila is typically a symbiont of free-living amoeba, and our understanding of the bacterial factors that determine human pathogenicity is limited. Here we carried out a population genomic study of 900 L. pneumophila isolates from human clinical and environmental. Legionella spp. are typically found in natural and artificially hydrated environments. Legionella pneumophila is the species responsible for ≈90% of human cases of infection. L. pneumophila is divided into 15 serogroups, among which serogroup 1 is the most prevalent disease-causing variant . In contrast, rare cases are caused by other serogroups Legionella pneumophila is a relatively common cause of both community-acquired and healthcare-associated pneumonia.Clinical manifestations are nonspecific, but high fever, diarrhea, and hyponatremia are often distinctive. Diagnostic modalities include culture on selective media and urinary antigen detection

  1. Only 19 cases of cutaneous involvement of Legionella sp. infections have been reported. Among these, only nine cases were related to L. pneumophila (), most of which occurred in immunocompromised patients and generally after a mild pulmonary episode identified as Pontiac fever.The overrepresentation of Legionella spp. other than L. pneumophila (50% of isolates) could be explained by a.
  2. Legionella pneumophila has the ability to replicate within human macrophages and amoebal hosts. Here, we report that the host cell cycle influences L. pneumophila intracellular replication. Our data demonstrate that the G 1 and G 2 /M phases of the host cell cycle are permissive for bacterial replication, while S phase is toxic for the bacterium.
