A simple, inexpensive slide agglutination test correctly identified the serogroup to which 38 Legionella pneumophilia strains belonged, and distinguished them from two atypical, Legionella-like organisms.

A new species of Legionella was isolated from soil collected from a creek bank. The name Legionella gormanii sp. nov. is proposed.

The presence of PCR inhibitors in water samples is well known and contributes to the fact that a practical PCR assay has not been developed for legionella surveillance. In this study, we devised a new seminested PCR assay for detection of Legionella spp. in water samples as a means of overriding the PCR inhibitors without loss of sensitivity. The seminested PCR assay utilized primers to amplify...

BACKGROUND Legionella is the causative agent of Legionnaires' disease, and hot springs are a major source of outbreaks of this disease. It is important from a public health perspective to survey hot spring environments for the presence of Legionella. METHODS Prospective surveillance of the extent of Legionella pollution was conducted at three hot spring recreational areas in Beijing, China in...

Legionella pneumophila, hafif seyirli pnömoniden, ağır pnömoni ve çoklu organ yetmezliğine kadar değişebilen klinik seyir gösteren, toplum hastane kaynaklı pnömonilere neden olabilen, sporadik veya salgınlar şeklinde ortaya çıkabilen bir bakteriyel etkenidir. akla getirilmezse tanıya yönelik testler istenmezse gözden kaçabilir. Burada, Covid -19 pandemisi döneminde acil servise yüksek ateş, öks...

We report a case of severe Legionnaires' disease (LD) complicated by a lung abscess in an immunocompetent patient who required ECMO therapy and thoracic surgery. The results of repeated Legionella quantitative real-time PCR performed on both sera and respiratory samples correlated with the LD severity and the poor clinical outcome. Moreover, the PCR allowed for the detection of Legionella DNA i...

A serological investigation has suggested that Legionella pneumophila may be associated with sore throat in adults. In a study of 177 adults and children with acute pharyngitis, Legionella species were not isolated from pharyngeal cultures, which utilized selective and nonselective buffered charcoal-yeast extract media. Group A beta-hemolytic streptococci were isolated from 14 percent of the 17...

An epidemiological investigation with Legionella and molecular subtyping was conducted to determine the source of a case of nosocomial Legionnaires' disease (LD) who was hospitalized in three hospitals within a month. Legionella pneumophila serogroup 3, an uncommon serogroup for infection, was isolated from the patient's sputum. Environmental surveillance revealed Legionella colonization in all...

BACKGROUND The Competence Network for Community Acquired Pneumonia (CAPNETZ) offers a unique opportunity to study the epidemiology of legionellosis throughout Germany, applying sophisticated diagnostic tools. METHODS The incidence, clinical characteristics, and outcome of Legionella pneumonia in 2503 adult patients with community-acquired pneumonia, participating in the German Multicenter Stu...

Human patients with mitochondrial diseases are more susceptible to bacterial infections, particularly of the respiratory tract. To investigate the susceptibility of mitochondrially diseased cells to an intracellular bacterial respiratory pathogen, we exploited the advantages of Dictyostelium discoideum as an established model for mitochondrial disease and for Legionella pneumophila pathogenesis...
