Distribution of lag-1 Alleles and Sequence-Based Types among Legionella pneumophila Serogroup 1 Clinical and Environmental Isolates in the United States

Sequence-based and monoclonal antibody typing of Legionella pneumophila isolated from patients in Portugal during 1987-2008

“…The significant profile diversity we observed is in accordance with reports from the other countries [4,14,16,17]. Due to the relatively low number of isolates in each ST, with the majority (13/23) of the STs being detected only once, it is not possible to establish a correlation between the ST and the infection origin.…”

Genotypic diversity of Legionella pneumophila in environmental and clinical strains assessed by Sequence-Based Typing, in association with retrospective clinical surveillance in Northern Italy

“…As other studies have shown [20,21,29,30,31], the presented confirms that the routine analysis of environmental strains may be an important strategy for preventing outbreaks of legionellosis, in association with clinical surveillance data.…”

“…The results were compared with those in the EWGLI database [25] which collates details of L. pneumophila strains, serogroups, monoclonal antibody subgroups and SBT profiles from all over the world [8,18,19,20,21], and with the authors'previous data [22,23,24].…”

Vital Signs: Deficiencies in Environmental Control Identified in Outbreaks of Legionnaires’ Disease — North America, 2000–2014

“…No clinical isolate was available for nine (33%) outbreaks, no environmental isolate was available for one (4%), and neither a clinical nor environmental isolate was available for two (7%); the clinical and environmental isolates did not match for the remaining two (7%) outbreaks. All available outbreak strains reacted with monoclonal antibody 2 of the international L. pneumophila serogroup 1 panel, a potential marker of increased virulence (11).…”
