The Contribution of Chemistry to the Detection and Enumeration of Legionella pneumophila in Environmental Water Samples: Experience With the MICA Method. [PDF]

Microbiologyopen
Legionella pneumophila is the principal species responsible for Legionnaires' disease, and measuring microbial load is fundamental to the analysis of environmental water samples. This study compared a new lipopolysaccharide bioprobe method (Microcolony Counter Analysis), which detects and counts L.

Impact of recommissioning flushing on Legionella pneumophila in a large building during the COVID-19 pandemic

Frontiers in Water, 2022
COVID-19 shutdowns drastically increased the frequency and duration of water stagnation events in building plumbing systems, urging local authorities to issue guidance for the safe reopening of buildings mostly by recommissioning flushing. The objectives

Diffuse alveolar hemorrhage due to Legionella pneumophila serogroup 3

Journal of Community Hospital Internal Medicine Perspectives, 2020
Legionella pneumophilia remains an important cause of pneumonia that can cause substantial clinical morbidity and mortality. We describe a case involving a 67-year-old woman with legionella pneumonia who developed diffuse alveolar hemorrhage.

Chemical characterization of lipopolysaccharides from Legionella feeleii, Legionella hackeliae and Legionella jordanis [PDF]

Microbiology, 1994
Lipopolysaccharides (LPS) from Legionella feeleii serogroup 1, L. hackeliae serogroup 1 and L. jordanis were subjected to chemical analysis. All three LPS contained D-mannose, D-glucose, D-glucosamine, L-glycero-D-manno-heptose, 2-keto-3-deoxyoctonic acid and glycerol. In addition the LPS of L.

Lower serum phosphate levels in patients with Legionella pneumonia relative to patients with non-Legionella pneumonia

Journal of Family Medicine and Primary Care, 2021
Introduction: Few studies have evaluated serum phosphate levels in patients with Legionella pneumonia admitted to hospitals in Japan. This study aimed to assess serum phosphate levels among inpatients with Legionella pneumonia on admission and compare ...

Legionella micdadei and Legionella dumoffii monoclonal antibodies for laboratory diagnosis of Legionella infections [PDF]

Journal of Clinical Microbiology, 1987
Two different monoclonal antibodies directed against Legionella micdadei and L. dumoffii (Genetic Systems Corp., Seattle, Wash.) were evaluated for their specificity and ability to detect L. micdadei and L. dumoffii in human and animal clinical samples and bacterial isolates in an indirect immunofluorescence assay.

The Legionella Kinase LegK2 Targets the ARP2/3 Complex To Inhibit Actin Nucleation on Phagosomes and Allow Bacterial Evasion of the Late Endocytic Pathway

mBio, 2015
Legionella pneumophila, the etiological agent of legionellosis, replicates within phagocytic cells. Crucial to biogenesis of the replicative vacuole is the Dot/Icm type 4 secretion system, which translocates a large number of effectors into the host cell

Effector Glycosyltransferases in Legionella [PDF]

Frontiers in Microbiology, 2011
Legionella causes severe pneumonia in humans. The pathogen produces an array of effectors, which interfere with host cell functions. Among them are the glucosyltransferases Lgt1, Lgt2 and Lgt3 from L. pneumophila. Lgt1 and Lgt2 are produced predominately in the post-exponential phase of bacterial growth, while synthesis of Lgt3 is induced mainly in the

Current perspectives on atypical pneumonia in children [PDF]

Clinical and Experimental Pediatrics, 2020
The major pathogens that cause atypical pneumonia are Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila. Community-acquired pneumonia (CAP) caused by M. pneumoniae or C.

Population Genomics of Legionella longbeachae and Hidden Complexities of Infection Source Attribution

Emerging Infectious Diseases, 2017
Legionella longbeachae is the primary cause of legionellosis in Australasia and Southeast Asia and an emerging pathogen in Europe and the United States; however, our understanding of the population diversity of L.
