We suspected non-pneumophila Legionella species pneumonia because of gardening habits, the negative urine antigen test and the non-significant Gram staining results of orange-coloured sputum. The pathogen was i
Legionella species are ubiquitously found in both natural and man-made water resources and live as a parasite of free-living amoeba species by forming biofilms (Abdel-Nour et al., 2019; Harding et al., 2013). The Legionella pneumophila is the most common cause for Legionellosis, accounting ...

pneumophila serogroup 1 strains. Even though L. pneumophila serogroup 1 is responsible for most Legionella pneumonia episodes, it is advisable to have techniques to detect other serogroups and species of Legionella especially in the hospital environment where the presence of non-serogroup 1 L. ...

Legionella spp. is recognized as a common cause of community acquired pneumonia, with Legionella pneumophila serogroup 1 being the most prevalent. At least 70 species are described so far but few are identified in pathogenic conditions. Data on extrapulm

Legionella pneumophila is a Gram-negative intracellular pathogen of both amoebae and humans that grows in lung macrophages. The intracellular replication strategy of this bacterium, which involves growth in a membrane-bound compartment called a vacuole, seems to be similar in all cell types in which...
The Gram-negative pathogenLegionella pneumophilais the causative agent for Legionnaires’ disease, a severe type of pneumonia resulting from infection of alveolar macrophages. Upon entry into its host cells, the bacterium utilizes its Dot/Icm type-IV secretion system (T4SS) to translocate at least ...
infections Legionella acts as an intracellular parasite and multiplies in alveolar macrophages. The genus Legionella contains 39 recognized species. The immunological diversity of Legionella is due to the existence of a variety of serogroups. Legionella pneumophila has the most with a total o...
