We have monitored the presence of bacteria belonging to the genus Legionella in the plumbing of buildings at the University of Perugia (Italy). More than 300 water samples were collected from 156 control-point taps in 41 buildings comprised in the eight campuses of the University. Legionella was absent in most samples, while it was found in only 12 buildings (29% of the total). Molecular analysis indicated the presence of L. pneumophila (serogroups 1, 8 and 6–10), L. taurinensis and L. anisa. In only three cases contamination levels were above the limit at which remedial actions are required, according to international guidelines. In two buildings, where the water temperature could be raised and maintained above 60 °C, thermal disinfection was effective in eradicating Legionella. Conversely, in buildings where contaminations were caused by heat exchangers that produced hot water at a maximum temperature of 50 °C, a chemical disinfection with silver hydrogen peroxide was carried out but was effective only in the short term. In this case study, Legionella contaminations and remediation effectiveness strongly depended on the network and heating-system characteristics, indicating how a multidisciplinary approach that integrates microbiological analysis with hydraulic surveys is necessary for an effective definition of Legionella prevention and control strategies.

This study analyzes the composition of viable fecal bacteria and gut toxicology biomarkers of 29 healthy volunteers, who followed omnivorous, lacto-ovo-vegetarian, or vegan diets. In particular, the research was focused on the prevalence of some representative viable bacteria from the four dominant phyla (Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria) commonly present in human feces, in order to evaluate the relationship between microorganisms selected by the habitual dietary patterns and the potential risk due to fecal water (FW) genotoxicity and cytotoxicity, considered as biomarkers for cancer risk and protective food activity. The relative differences of viable bacteria among dietary groups were generally not statistically significant. However, compared to omnivores, lacto-ovo-vegetarians showed low levels of total anaerobes. Otherwise, vegans showed total anaerobes counts similar to those of omnivores, but with lower number of bifidobacteria and the highest levels of bacteria from the Bacteroides–Prevotella genera. FW genotoxicity of lacto-ovo-vegetarians resulted significantly lower either in relation to that of omnivores and vegans. Lacto-ovo-vegetarians also showed the lowest levels of cytotoxicity, while the highest were found for vegans. These results highlighted that lacto-ovo-vegetarian diet was particularly effective in a favorable modulation of microbial activity, thus contributing to a significant reduction of the genotoxic and cytotoxic risk in the gut.

This paper investigates the presence of Legionella in the water distribution systems of buildings of the University of Perugia (Italy). Further, as the genus Legionella comprises many different species and serogroups, of which L. pneumophila sg1 is the most often associated to human lung infections, a molecular characterization of the retrieved Legionella isolates is reported.

Legionella was monitored by standard methods analyzing more than 300 water samples collected from 100 taps throughout the university campus. Legionella was absent in the great majority of the samples, while it was found in only five buildings of the entire campus. Molecular analysis indicated that the contaminations were only partially ascribed to L. pneumophila sg1, as other serogroups (sg8 and sg10) as well as other species (L. taurinensis and L. anisa) were also found. Further, in only three cases the levels of contamination were above the limit at which, according to international guidelines, remedial actions are required. In particular, a thermal disinfection, i.e., raising the water temperature above the level at which Legionella cells do not survive, was applied to the hot water supply systems where high temperature could be maintained throughout. On the contrary, in a building in which Legionella contamination originated inside the heat exchanger, a chemical disinfection with silver hydrogen peroxide was carried out.

The case study herein reported indicates how a multidisciplinary approach that integrates microbiological analysis with the survey of building’s plumbing systems can lead to the definition of effective strategies for Legionella prevention and control.
