Non-chemical weeds management in two Mediterranean culinary herbs
2009
Weeds management is one of the most relevant constraints to the cultivation of Medicinal and Aromatic Plants, especially when they’re cultivated with “organic” methods, that, according to EU regulations, do not allow the use of chemicals. A strong interest is therefore devoted to pointing out “alternative” (agronomical and physical) methods for weeds control. This work reports the results of a trial performed in 2003-04 and 2004-05 in order to evaluate the effects on Coriander (Coriandrum sativum L.) and Fennel (Foeniculum vulgare Mill.) of four non-chemical methods for weeds control: FS (False seeding), PD (Flaming), MZ (Mechanical weeding), SM (Hand weeding) compared with two untreated co…
Variations in the Volatile Compounds of a Fennel (Foeniculum VulgareMill.) Variety Grown in a Semi-Arid Mediterranean Environment
2005
Abstract Fennel is an industrial source of anethole but, recently, further interest has came from the suggested possibility of many industrial uses of this plant.The volatile substances from the seeds of Fennel grown in Sparacia (Cammarata – AG – Sicily; 37° 38’ N; 13° 46’ E) have been investigated and compared on a statistical base with previously reported data. The variety grown in Sparacia fall into the “high fenchone” chemovariety. The substances α-toluene, α-terpinene, β-phellandrene+limonene and camphene appear the components most sensitive to environment and grow condition modifications.
Metabolic Profiling and Metabolite Correlation Network Analysis Reveal That Fusarium solani Induces Differential Metabolic Responses in Lotus japonic…
2021
Root fungal endophytes are essential mediators of plant nutrition under mild stress conditions. However, variations in the rhizosphere environment, such as nutrient depletion, could result in a stressful situation for both partners, shifting mutualistic to nonconvenient interactions. Mycorrhizal fungi and dark septate endophytes (DSEs) have demonstrated their ability to facilitate phosphate (Pi) acquisition. However, few studies have investigated other plant–fungal interactions that take place in the root environment with regard to phosphate nutrition. In the present research work, we aimed to analyze the effect of extreme Pi starvation and the fungal endophyte Fusarium solani on the model …
MRSA infection in the neonatal intensive care unit
2013
Methicillin-resistant Staphylococcus aureus (MRSA) is well known as one of the most frequent etiological agents of healthcare-associated infections. The epidemiology of MRSA is evolving with emergence of community-associated MRSA, the clonal spread of some successful clones, their spillover into healthcare settings and acquisition of antibacterial drug resistances. Neonatal intensive care unit (NICU) patients are at an especially high risk of acquiring colonization and infection by MRSA. Epidemiology of MRSA in NICU can be very complex because outbreaks can overlap endemic circulation and make it difficult to trace transmission routes. Moreover, increasing prevalence of community-associated…
Outbreak of colonizations by extended-spectrum β-lactamase-producing Escherichia coli sequence type 131 in a neonatal intensive care unit, Italy
2013
Abstract Background Extended spectrum β-lactamases (ESBLs) often associated with resistance to aminoglycosides and fluoroquinolones have recently emerged in community-associated Escherichia coli. The worldwide clonal dissemination of E. coli sequence type (ST)131 is playing a prominent role. We describe an outbreak of colonizations by ESBL-producing E. coli (ESBL-E. coli) in the neonatal intensive care unit (NICU) of the University Hospital, Palermo, Italy. Methods An epidemiological investigation was conducted with the support of molecular typing. All children admitted to the NICU and colonized by ESBL-E. coli between January and June 2012, were included in the study. Cases were defined as…
Is there a widespread clone of Serratia marcescens producing outbreaks worldwide?
2021
[Background]: Serratia marcescens frequently causes outbreaks in healthcare settings. There are few studies using high-throughput sequencing (HTS) that analyse S. marcescens outbreaks. We present the analysis of two outbreaks in neonatal intensive care units (NICUs) in hospitals from the Comunitat Valenciana (CV, Spain) and the impact of using different reference genomes.
Community Composition, Antifungal Activity and Chemical Analyses of Ant-Derived Actinobacteria
2020
Actinobacteria associated with insects represent one potentially rich source of novel natural products with antifungal activity. Here, we investigated the phylogenetic diversity and community composition of actinobacteria associated with ants using a combination of culture-dependent and -independent methods. Further, we assessed the antagonistic activity against phytopathogenic fungi and identified the secondary metabolites from isolates with bioactivity. A total of 416 actinobacterial isolates were obtained from three ant species (Camponotus japonicus, Lasius fuliginosus, and Lasius flavus) located in five nests. The largest amount of isolates were observed in the head samples. 16S rRNA ge…
Genetic divergence between morphological forms of brown troutSalmo truttaL. in the Balkan region of Macedonia
2010
The objective of this study was to characterize the genetic structure of two Balkan brown trout morphotypes, Salmo macedonicus and Salmo pelagonicus, and to test whether molecular traits support the species’ status proposed by traditional morphological identification. The mitochondrial DNA 12S-rDNA, cyt b and control region genes were sequenced in 15 specimens collected from three localities in the Former Yugoslav Republic of Macedonia. The results of these markers did not support the taxonomic category of species but confirmed the existence of two morphotypes, Salmo trutta macedonicus and Salmo trutta pelagonicus, in the Aegean–Adriatic lineages of the Salmo trutta species complex.
Epidemic spread of ST1-MRSA-IVa in a neonatal intensive care unit, Italy
2012
Abstract Background Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has recently emerged as an important pathogen in neonatal intensive care units (NICUs). The purposes of this study were to characterize methicillin-resistant isolates from an outbreak in a NICU, to examine the genetic traits and clonality of CA-MRSA, and to review the characteristics and outcomes of the neonatal cases and investigate the routes of entry and transmission of the MRSA outbreak strain in the NICU under study. Methods The study NICU practiced an active surveillance program for multidrug-resistant organisms, including weekly cultures for detection of MRSA from nasal swabs among all the …
Risk Factors for Sensorineural Hearing Loss and Auditory Maturation in Children Admitted to Neonatal Intensive Care Units: Who Recovered?
2022
Background: Newborns admitted to neonatal intensive care units (NICUs) are at higher risk of developing sensorineural hearing loss (SNHL), which may improve over time. The aim of this study was to describe the prevalence of the main risk factors for SNHL in a NICU cohort, focusing on children who underwent auditory maturation. Methods: An observational study of 378 children admitted to NICUs, who were followed for at least 18 months, with periodic audiologic assessments. Results: Out of 378 patients, 338 had normal hearing and 40 were hearing-impaired; we found a higher percentage of extremely preterm (EPT) and extremely low-birthweight (ELBW) infants in SNHL children (p < 0.05). Sevente…
