Legionnaires' disease (LD) is an often severe and potentially fatal form of bacterial
pneumonia caused by an extensive list of Legionella species. These ubiquitous freshwater …

Legionella are opportunistic pathogens that develop in aquatic environments where they
multiply in protozoa. When infected aerosols reach the human respiratory tract they may …

For bacterial typing to be useful, the development, validation and appropriate application of
typing methods must follow unified criteria. Over a decade ago, ESGEM, the ESCMID …

Water is the major natural reservoir for legionellae, and the bacteria are found worldwide in
many different natural and artificial aquatic environments, such as cooling towers, water …

ABSTRACT A previously described sequence-based epidemiological typing method for
clinical and environmental isolates of Legionella pneumophila serogroup 1 was extended …

ABSTRACT Representatives (n= 31) of outbreak strains of Acinetobacter baumannii from
five countries fell into three clear groups, designated Groups 1–3, based on their ompA …

Objectives Epidemiological investigations of Legionnaires' disease outbreaks rely on the
rapid identification and typing of clinical and environmental Legionella isolates in order to …

Multilocus sequence typing (MLST) is a widely used system for typing microorganisms by
sequence analysis of housekeeping genes. The main advantage of MLST in comparison to …

Since the establishment of sequence-based typing as the gold standard for DNA-based
typing of Legionella pneumophila, the Legionella laboratory at the Centers for Disease …

A first strong evidence of person-to-person transmission of Legionnaires' Disease (LD) was
recently reported. Here, we characterize the genetic backbone of this case-related …
