We have developed a novel method to detect PCR products from pathogen genome DNA by Zinc finger protein that can bind to double strand DNA (dsDNA) in sequence specific manner. In this study, we tried to detect Legionella pneumophila strain Philadelphia 1 using Zinc finger protein. We found the specific target DNA sequence for zinc finger protein Sp2 in L. pneumophila strain Philadelphia 1 genome DNA. Specific PCR product was successfully amplified from L. pneumophila strain Philadelphia 1 genome DNA and we used Zinc finger protein Sp2 to detect it. We succeeded in detecting the PCR products from L. pneumophila strain Philadelphia 1 genome DNA with Sp2.

HtpB, the chaperonin of the bacterial pathogen , is found in extracellular locations, even the cytoplasm of host cells. Although chaperonins have an essential cytoplasmic function in protein folding, HtpB exits the cytoplasm to perform extracellular virulence-related functions that support 's lifestyle. The mechanism by which HtpB reaches extracellular locations is not currently understood.

Background: Although antimicrobial resistance has not yet emerged as an overarching problem for Legionella pneumophila (Lp) infection, the description of clinical and environmental strains resistant to fluoroquinolones and macrolides is a cause of concern. This study aimed to investigate the antimicrobial susceptibility of Lp human isolates in Italy.
Methods: A total of 204 Lp clinical isolates were tested for sensitivity to nine antibiotics using the broth microdilution assay (BMD).

Legionella pneumophila, the causative agent of Legionnaires' disease, employs the Icm/Dot Type IV secretion system (T4SS) to replicate in amoebae and macrophages. The opportunistic pathogen responds to stress by forming 'viable but non-culturable' (VBNC) cells, which cannot be detected by standard cultivation-based techniques. In this study, we document that L.

Antimicrobial resistance is an emerging problem in hospitals and long-term healthcare facilities. Early detection of susceptibility pattern changes in pathogenic bacteria can prevent treatment failures. Therefore, this study chose to investigate the antibiotic susceptibility situation of isolates from hospitals and long-term healthcare facilities in Southern Germany.

Whole genome sequencing (WGS) marks a turning point for outbreak investigations for microorganisms related to public health matters, like Legionella pneumophila (Lp). Here, we evaluated the available Lp WGS typing tools for isolates of previously documented Belgian outbreaks, as well as small groups of related and non-related isolates. One reference strain and 77 clinical and environmental isolates were evaluated.
