NDM-1-producing Acinetobacter baumannii ST85 now in Turkey, including one isolate from a Syrian refugee.
2015
PubMedID: 26296677 New Delhi metallo-b-lactamase-1 (NDM-1), an acquired class B carbapenemase, is a significant clinical threat owing to the extended hydrolysis of ß-lactams including carbapenems. Here, to the best of our knowledge we describe for the first time in Turkey two NDM-1- producing Acinetobacter baumannii isolates recovered from intensive care unit patients. The presence of blaNDM-1 was detected by PCR and confirmed by sequencing. The clonal relationship was assessed by PFGE and multilocus sequence typing. Both isolates were positive for blaNDM-1 and were attributed with the sequence type 85. One isolate was from a Syrian refugee, whereas the second was from a patient who had nev…
Characterization of Acinetobacter baumannii from intensive care units and home care patients in Palermo, Italy.
2011
AbstractIn this study 45 isolates of Acinetobacter baumannii identified from patients in intensive care units of three different hospitals and from pressure ulcers in home care patients in Palermo, Italy, during a 3-month period in 2010, were characterized. All isolates were resistant to at least three classes of antibiotics, but susceptible to colistin and tygecycline. Forty isolates were non-susceptible to carbapenems. Eighteen and two isolates, respectively, carried the blaOXA-23-like and the blaOXA-58-like genes. One strain carried the VIM-4 gene. Six major rep-PCR subtype clusters were defined, including isolates from different hospitals or home care patients. The sequence type/pulsed …
New β-Lactam-β-Lactamase Inhibitor Combinations.
2020
The limited armamentarium against drug-resistant Gram-negative bacilli has led to the development of several novel β-lactam-β-lactamase inhibitor combinations (BLBLIs). In this review, we summarize their spectrum of in vitro activities, mechanisms of resistance, and pharmacokinetic-pharmacodynamic (PK-PD) characteristics. A summary of available clinical data is provided per drug. Four approved BLBLIs are discussed in detail. All are options for treating multidrug-resistant (MDR) Enterobacterales and Pseudomonas aeruginosa Ceftazidime-avibactam is a potential drug for treating Enterobacterales producing extended-spectrum β-lactamase (ESBL), Klebsiella pneumoniae carbapenemase (KPC), AmpC, an…
Trends, risk factors and outcomes of health care associated infections within the Italian network SPIN-UTI
2013
Summary Background Implementing infection control measures in light of healthcare-associated infection (HAI) surveillance data can prevent HAIs. Surveillance has been associated with a reduction of HAI in intensive care unit (ICU) patients, though the reasons for this improvement remain unclear. Aim To evaluate changes in healthcare-associated infection (HAI) rates during three surveys of the Italian Nosocomial Infections Surveillance in Intensive Care Units (ICUs) network (SPIN-UTI) six-year project and to explore sources of variation of indicators of HAI in the 65 participating ICUs. Methods The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Cumulative…
On-Demand Isolation of Bacteriophages Against Drug-Resistant Bacteria for Personalized Phage Therapy
2015
Bacteriophages are bacterial viruses, capable of killing even multi-drug resistant bacterial cells. For this reason, therapeutic use of phages is considered as a possible alternative to conventional antibiotics. However, phages are very host specific in comparison to wide-spectrum antibiotics and thus preparation of phage-cocktails beforehand against pathogens can be difficult. In this study, we evaluate whether it may be possible to isolate phages on-demand from environmental reservoir. We attempted to enrich infectious bacteriophages from sewage against nosocomial drug-resistant bacterial strains of different medically important species in order to evaluate the probability of discovering …
Epidemiology and Pattern of Resistance of Gram-Negative Bacteria Isolated from Blood Samples in Hospitalized Patients: A Single Center Retrospective …
2021
Background: Blood culturing remains the mainstream tool to inform an appropriate treatment in hospital-acquired bloodstream infections and to diagnose any bacteremia. Methods: A retrospective investigation on the prevalence of Gram-negative bacteria (GNB) and their resistance in hospitalized patients by age, sex, and units from blood cultures (BCs) was conducted from January 2018 to April 2020 at Sant’Elia hospital, Caltanissetta, southern Italy. We divided the patient age range into four equal intervals. Results: Multivariate demographic and microbiological variables did not show an association between bacteria distributions and gender and age. The distribution by units showed a higher pre…
Pierwsza nowoczesna retrotopia? "Don Kichote" Miguela de Cervantesa w perspektywie późnego Zygmunta Baumana
2022
The article considers Cervantes's classical work through the prism of retrotopia, as understood in late Bauman. Retrotopia is a double negation of utopia, an attempt to return to an imaginary past, which usually happens in the face of an uncertain future. The first part of the article indicates a clear analogy between the conceptualization of retrotopia and Don Quixote's key themes. These include the issue of nostalgia for times past, the problem ofviolence,ora return to tribal thinking in terms o f”us” versus "them.” The second part o f the text briefly examines Don Quixote as an expression of retrotopian longing for an imaginary past o f a Golden Age, an idyllic era of justice and humanis…

Chemical investigation of secondary metabolites from the endophytic fungus Pseudopestalotiopsis theae led to the isolation of eighteen new polyketide derivatives, pestalotheols I&ndash
Induction of ambuic acid derivatives by the endophytic fungus Pestalotiopsis lespedezae through an OSMAC approach
2021
Abstract Ten new ambuic acid derivatives, pestallic acids H–Q including one new iodinated natural product along with two known compounds, ambuic acid and ambuic acid 18-acetate, were obtained through fermentation of the endophytic fungus Pestalotiopsis lespedezae on solid rice medium with 3.5% NaI. Pestallic acids H–Q were undetectable in cultures of the fungus grown on solid rice medium lacking NaI or in those where NaI had been replaced by NaCl or NaBr. The structures of the new metabolites were established on basis of 1D/2D NMR and HRESIMS data. Their absolute configurations were determined by Mosher’s method and TDDFT-ECD calculations. The compounds failed to show antibacterial activity…
Stratificazione ontologica e fluidità del reale
2013
The question of reality implies the necessity of declaring a principle of reality. Thus, it means the necessity of declaring a principle of existence. Through the adoption of a wide criterion like that of intentional existence following up on Quine’s accounts, the question is reformulated as a question concerning not what but how being is. Using Bauman’s concept of liquidity in an ontological manner and discussing Malabou’s notion of plasticity, the form as essence is seen in its possibility of being receptive and fluid and not ontologically static or stiff. Facing a stratified reality, we need to insert phenomenology and hermeneutics into metaphysics or rather rediscover the originary phen…
