The colonization of sicily by the Black Kite (Milvus migrans)

2003

I describe the colonization of the black kites (Milvus migrans) in Sicily. The ancient ornithologists of the ninth century considered this species as occasional and rare in Sicily. The black kite has been classified as the second mosto common species observed in the Strait of Messina in spring and is also most abundant during fall migration. Habitats suitable for nesting are available along the migratory route. This species is reproducing and remaining during the winter in an approximate area of 100 kmq located in the center of Sicily. The first confirmed reproductive data was reported in 1979, later a more extensive colonization followed. Stadia tardla was recorded during vehicle censuses …

Colonizzazione da batteri Gram negativi multi-resistenti in pazienti pediatrici

2017

INTRODUZIONE: La diffusione della resistenza batterica in ospedale e in comunità costituisce un serio motivo di allarme anche nella popolazione pediatrica. Recenti studi hanno dimostrato come le infezioni sostenute da batteri gram-negativi multiresistenti (MDRGN) oggi si presentino sempre più frequentemente anche in comunità, e come più del 15% dei bambini siano colonizzati da MDRGN al momento del ricovero in ospedale. L’introduzione di questi microrganismi in comunità rappresenta un serio fattore di rischio per lo sviluppo di infezioni difficilmente trattabili. Il nostro studio ha indagato la presenza di batteri MDRGN nella popolazione microbica intestinale di bambini ricoverati con sintom…

La fasciatura dei feriti: uno schema di origine classica nel fregio della Colonna Traiana

2017

Nella ricchissima letteratura sulla Colonna Traiana, un filone di ricerca non ancora esplorato in tutte le sue potenzialità è lo studio approfondito degli schemi iconografici di origine greca rifluiti nella narrazione figurata delle guerre daciche. Sono formule che erano da tempo patrimonio comune degli artisti romani, con una lunga storia di riprese e adattamenti. L’analisi di un caso di particolare interesse costituisce un’ulteriore conferma di come, all’interno della prassi artistica romana, gli ideatori dei programmi iconografici ufficiali utilizzassero un codice formale in cui motivi figurativi del passato erano stati ormai assimilati e rifunzionalizzati. A field of research not yet in…

Increasing the levels of 2-phenylethyl acetate in wine through the use of a mixed culture of Hanseniaspora osmophila and Saccharomyces cerevisiae

2009

The impact of mixed cultures of Hanseniaspora osmophila and Saccharomyces cerevisiae with different initial yeast ratios on wine composition has been examined. The mixed culture significantly affected sugar consumption, the main enological parameters and ester concentrations, with the exception of glycerol, isoamyl acetate and diethyl succinate levels. Remarkably, in wines obtained with mixed cultures the concentration of 2-phenylethyl acetate was approximately 3- to 9-fold greater than that produced by S. cerevisiae pure culture. Moreover sensory evaluation revealed a stronger fruity character in wines fermented with mixed cultures than in control wines. Independently of the mixed culture …

Comparison of the efficacy of chemomechanical caries removal (Carisolv') with that of conventional excavation in reducing the cariogenic flora

2004

Summary.  Objectives.   The usage of minimally invasive procedures and attention to patient comfort are of great importance, especially for dental treatment in small children. This has led to the development of chemomechanical methods for caries removal. The aim of this study was to compare the efficacy of chemomechanical caries removal with that of conventional excavation in reducing the count of the cariogenic flora. Design and setting.  Subjects for this study were chosen from children admitted to dental clinic for restorative procedures under general anaesthesia. Samples and methods.  Twenty-one children (mean age 43·5 ± 12·0 months) with early childhood caries were included in this stu…

Colonization pattern of primary tomato roots by Pseudomonas fluorescens A6RI characterized by dilution plating, flow cytometry, fluorescence, confoca…

2004

Early colonization of primary tomato roots, grown in vitro, by Pseudomonas fluorescens A6RI, introduced by seed bacterization, was monitored for 7 days in three different root zones (zone A, apex+elongation+young hairy zone; zone B, hairy zone; zone C, old hairy zone+collar). Bacterial quantification was assessed by enumeration of (i) colony forming units (cfu) after dilution plating and of (ii) total bacterial cells by flow cytometry. Bacterial distribution and organization in the root zones were analyzed by fluorescence, confocal and scanning electron microscopy. For all sampling dates and zones, the densities of total bacterial cells were significantly higher than those of the cfu. The k…

Survival Strategy of Erwinia amylovora against Copper: Induction of the Viable-but-Nonculturable State

2006

Copper compounds, widely used to control plant-pathogenic bacteria, have traditionally been employed against fire blight, caused by Erwinia amylovora. However, recent studies have shown that some phytopathogenic bacteria enter into the viable-but-nonculturable (VBNC) state in the presence of copper. To determine whether copper kills E. amylovora or induces the VBNC state, a mineral medium without copper or supplemented with 0.005, 0.01, or 0.05 mM Cu2+ was inoculated with 107 CFU/ml of this bacterium and monitored over 9 months. Total and viable cell counts were determined by epifluorescence microscopy using the LIVE/DEAD kit and by flow cytometry with 5-cyano-2,3-ditolyl tetrazolium chlori…
