Amaç: Bu çalışmada hastane içme, kullanma suyu ve sürüntü örnekleri mikrobiyolojik yönden incelenerek, risk oluşturup oluşturmadığı araştırıldı.Materyal Metot: Araştırmamızda 40 farklı içme başlıklarından alınan su ayrı olarak yöntemlerle incelendi. Su örneklerinin analizleri için membran filtrasyon yöntemi tek koloni düşürme ekim kullanıldı. Ayrıca kullanılan besiyerlerinde üreyen mikroorganiz...
Endocarditis due to Legionella spp. is uncommon but presumably underestimated given the prevalence of Legionellae in the environment. We report a first and unusual case of chronic native valve endocarditis due to L. anisa and advocate that the diagnosis of endocarditis be made collaboratively between the cardiologist, surgeon, microbiologist and pathologist.
The occurrence and densities of opportunistic pathogens (OPs), the microbial community structure, and their associations with sediment elements from eight water storage tanks in Ohio, West Virginia, and Texas were investigated. The elemental composition of sediments was measured through X-ray fluorescence (XRF) spectra. The occurrence and densities of OPs and amoeba hosts (i.e., Legionella spp....
A cross-sectional multicenter survey of Italian hotels was conducted to investigate Legionella spp. contamination of hot water. Chemical parameters (hardness, free chlorine concentration, and trace element concentrations), water systems, and building characteristics were evaluated to study risk factors for colonization. The hot water systems of Italian hotels were strongly colonized by Legionel...
Introduction Concurrent infections or co-infections in patients diagnosed with Coronavirus Disease-19 (COVID-19) are not uncommon and predict a pejorative prognosis. A co-infection accounts for 1 out of every 5 cases COVID-19 increases the likelihood adverse health outcomes such as mechanical ventilations, ICU admissions, death. Specifically, Legionella spp. presents additional challenges becau...
A total of 123 water samples were examined in parallel by culture and semi-nested PCR for the presence of Legionella. They comprised: 35 samples of hot water distributed by the urban municipal water supply system (MWSS) taken in institutions, 45 samples of hot water distributed by urban MWSS taken in dwellings, 27 samples of cold water distributed by rural MWSS taken in dwellings, and 16 sample...
Copper-silver (Cu-Ag) ionization has effectively controlled Legionella spp. in the hot water systems of numerous hospitals. However, it was ineffective at controlling Legionella in one Ohio hospital despite the confirmation of adequate total concentrations of copper and silver ions. The pH of the water at this hospital was found to be 8.5 to 9.0. The purpose of this study was to investigate the...
INTRODUCTION AND OBJECTIVE Several studies have reported therapy failures in patients with legionnaires'disease; however, antimicrobial resistance of clinical and environmental isolates of Legionella spp. has not yet been documented. Routine susceptibility testing of Legionella spp. is not recommended because of difficulties in determining standard minimal inhibitory concentration values. The p...
Using fluorescence in situ hybridization to detect bacterial groups has several inherent limitations. DNA probes are generally used, targeting sites on the 16S rRNA. However, much of the 16S rRNA is highly conserved, with variable regions often located in inaccessible areas where secondary structures can restrict probe access. Here, we describe the use of peptide nucleic acid (PNA) probes as a ...
