| legionella risk assessment in cruise ships and ferries. | <b>introduction.</b> the increasing development of marine traffic has led to a rise in the incidence of legionellosis among travellers. it occurs in similar environments, especially closed and crowded, and aboard ships legionella survives and multiplies easily in water pipes, spreading into the environment through air conditioning systems and water distribution points. although in recent years in the construction of cruise ships preventive measures aimed at curbing the proliferation of legionell ... | 2017 | 28664708 |
| [evaluation of biological indicators of hygienic quality in modern dental clinics with a high perceived quality in catania (italy)]. | a study was performed to evaluate safety and hygienic quality levels in dental clinics in catania (sicily, italy). microbiological checks of air samples, surfaces and water were performed in seven modern dental clinics with a high perceived quality of care. in total, 16 active dental units were present in the clinics included in the study. water samples were obtained from dental air-water syringes and directly from the water supply and analyzed to determine aerobic mesophilic bacteria counts, co ... | 2010 | 21358774 |
| a combined molecular typing approach does not discriminate legionella pneumophila serogroup 1 strains of a predominant sequence-based type in palermo, italy. | the sequence-based type 1,4,3,1,1,1 of legionella pneumophila sg.1 is predominant in the palermo city environment since several years. in this study, extended sequence-based typing and pulsed field gel electrophoresis were used in a combined approach in the aim to enhance discriminatory power of the molecular typing procedures. however, probably due to a common environmental reservoir and genetic stability, most of the strains circulating in the geographic area under study belong to the same clo ... | 2009 | 20701881 |
| genotyping of legionella pneumophila serogroup 1 strains isolated in northern sicily, italy. | during a three-year period, from april 2002 to may 2005, one hundred-forty-seven samples, taken from technical systems of water distribution at point of use, were repeatedly collected at six different sites in northern sicily and assayed for the presence of legionella pneumophila serogroup 1 and serogroups 2 to 14. at the first samplings, the water distribution systems of all the sites were heavily contaminated, and disinfection treatments by the superheat and flush method were therefore perform ... | 2008 | 18623987 |
