Biochemical biomarkers alterations in Coronavirus Disease 2019 (COVID-19)
2020
Abstract Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a respiratory disease, which can evolve into multi-organ failure (MOF), leading to death. Several biochemical alterations have been described in COVID-19 patients. To date, many biomarkers reflecting the main pathophysiological characteristics of the disease have been identified and associated with the risk of developing severe disease. Lymphopenia represents the hallmark of the disease, and it can be detected since the early stage of infection. Increased levels of several inflammatory biomarkers, including c-reactive protein, have been found in COVID-19 patients and associ…
OXA-48-producing Klebsiella pneumoniae in a neonatal intensive care unit in Palermo, Italy
2014
Objectives Surveillance cultures are of great importance to detect the emergence of multidrug resistant (MDR) bacteria in high-risk settings and prevent the occurrence of colonization and clinical infection cases. We report the isolation of OXA-48-harbouring Klebsiella pneumoniae sequence type (ST) 530 in a Neonatal Intensive Care Unit (NICU) in Palermo, Italy. Methods Since June 2009, a routine surveillance protocol is in place in the NICU of the University Hospital of Palermo, including nasal and rectal swabs obtained on a weekly basis to monitor the prevalence of colonization by methicillin- resistant Staphylococcus aureus, MDR Gram-negatives and glycopeptide-resistant enterococci. Enter…
Stipiti di Klebsiella pneumoniae resistenti ai carbapenemi circolanti in differenti reparti dell'A.O.U.P. "P. Giaccone" di Palermo

Genomic epidemiology and antimicrobial resistance of Klebsiella pneumoniae in the Comunitat Valenciana
2023
La resistencia antimicrobiana (RAM) es una importante amenaza para la salud pública a nivel mundial. El mal uso de los antibióticos ha llevado al surgimiento y propagación de infecciones resistentes a los antibióticos. Entre los patógenos que más muertes causan asociadas a la RAM bacteriana se encuentra Klebsiella pneumoniae, uno de los patógenos más preocupantes. DE hecho, en 2019, K. pneumoniae se clasificó como la segunda causa de muertes atribuible a la RAM. Entre las resistencias adquiridas en K. pneumoniae, las que mayor preocupación causan son las cepas que han desarrollado resistencia a cefalosporinas de tercera generación (3GC) y carbapenems (CRKp). En esta tesis se ha investigado …
GRM2 tipa bakteriālo mikrokompartmentu daļiņu raksturojums
2020
Bakteriālie mikrokompartmenti (BMC) ir baktēriju organellas, kas iepako enzīmus proteīnu čaulā. Šī darba mērķis bija analizēt iespējas GRM2 tipa BMC iepakot heterologus enzīmus, kā arī apskatīt rekombinanti producētu BMC čaulas īpašības. Šajā darbā Klebsiella pneumoniae GRM2 tipa BMC čaulā tika testēta trīs Zymomonas mobilis etanolģenēzes enzīmu iepakošana kā starpnieku izmantojot natīvo CutC holīna liāzes enzīmu un SpyTag/SpyCatcher adhezīnu sistēmu. Veikta arī bakteriālo mikrokompartmentu čaulas analīze ar cryo-EM. Darba ietvaros veikts konstruktu dizains, proteīnu ekspresija, attīrīšana, un analīze ar TEM un cryo-EM. Rezultāti liecina par zemu iepakošanas efektivitāti, ja kā mediators iz…
Draft Genome Sequence and Biofilm Production of a Carbapenemase-Producing
2021
Rapid identification and characterization of multidrug-resistant Klebsiella pneumoniae strains is essential to diagnose severe infections in patients. In clinical routine practice, K. pneumoniae is frequently identified and characterized for outbreak investigation. Pulsed-field gel electrophoresis or multilocus sequence typing could be used, but, unfortunately, these methods are time-consuming, laborious, expensive, and do not provide any information about the presence of resistance and virulence genes. In recent years, the decreasing cost of next-generation sequencing and its easy use have led to it being considered a useful method, not only for outbreak surveillance but also for rapid ide…

Thermodynamics of the Interaction between the Spike Protein of Severe Acute Respiratory Syndrome Coronavirus-2 and the Receptor of Human Angiotensin-…
2020
Since the end of 2019, the coronavirus SARS-CoV-2 has caused more than 1000000 deaths all over the world and still lacks a medical treatment despite the attention of the whole scientific community. Human angiotensin-converting enzyme 2 (ACE2) was recently recognized as the transmembrane protein that serves as the point of entry of SARS-CoV-2 into cells, thus constituting the first biomolecular event leading to COVID-19 disease. Here, by means of a state-of-the-art computational approach, we propose a rational evaluation of the molecular mechanisms behind the formation of the protein complex. Moreover, the free energy of binding between ACE2 and the active receptor binding domain of the SARS…
Is the Rigidity of SARS-CoV-2 Spike Receptor-Binding Motif the Hallmark for Its Enhanced Infectivity? Insights from All-Atom Simulations
2020
The severe acute respiratory syndrome coronavirus (SARS-CoV-2) pandemic is setting the global health crisis of our time, causing a devastating societal and economic burden. An idiosyncratic trait of coronaviruses is the presence of spike glycoproteins on the viral envelope, which mediate the virus binding to specific host receptor, enabling its entry into the human cells. In spite of the high sequence identity of SARS-CoV-2 with its closely related SARS-CoV emerged in 2002, the atomic-level determinants underlining the molecular recognition of SARS-CoV-2 to the angiotensin-converting enzyme 2 (ACE2) receptor and, thus, the rapid virus spread into human body, remain unresolved. Here, multi-m…
