In this study, protamine was covalently coated on the surface of the MNPs (20-30 nm) by a three-step chemical reaction. The successful linkage of protamine to the MNPs was confirmed by Fourier transform infrared spectroscopy (FTIR), zeta potential, and transmission electron microscopy (TEM). When used for concentrating HAV from 40 mL of milk, 50 μL of PMNPs were added to the sample and mixed for 20 min by gentle rotation, followed by a magnet capture for 30 min. The captured PMNPs were washed with glycine buffer (0.05 M glycine, 0.14 M NaCl, 0.2% (v/v) Tween 20, pH 9.0) and HAV RNA was extracted using the ...

Brassard J Abstract The viability of murine norovirus (MNV-1), bovine rotavirus (boRV), and hepatitis A virus (HAV) was evaluated at 21 °C, 4 °C, and -20 °C on stainless steel surfaces, in bottled water, and on blueberries for up to 21 days. After 14 days of incubation at 21 °C on stainless steel, a viability loss>4 log for MNV-1,>8 log for boRV, and>1 log for HAV was observed. Losses were observed for MNV-1 (>1 log) and HAV (>2 log) incubated in water at 21 °C for 21 days. No significant loss was detected for MNV-1 and HAV at 4 °C and -20 °C and for boRV a...

Publication date: Available online 12 August 2019Source: Food ControlAuthor(s): Jiayin Chen, Xiyang Wu, Gloria Sánchez, Walter RandazzoAbstractBerries have frequently been cited as causing gastroenteritis and acute hepatitis outbreaks due to enteric virus contamination, including human norovirus and hepatitis A virus (HAV). Model experiments were performed to evaluate the potential use of viability RT-qPCR to assess the thermal inactivation of norovirus genotype I (GI), GII, and HAV on raspberries, blueberries and strawberries. Initially, two viability markers, platinum chloride and propidium monoazide (PMAxx™...

Picornaviruses constitute one of the most relevant viral groups according to their impact on human and animal health. Etiologic agents of a broad spectrum of illnesses with a clinical presentation that ranges from asymptomatic to fatal disease; they have been the cause of uncountable epidemics throughout history. Picornaviruses are small naked RNA-positive-stranded viruses which include some of the most important pillars in the development of virology, comprising Poliovirus, Rhinovirus, and Hepatitis A virus. Picornavirus infectious particles use the fecal-oral or respiratory routes as primary modes of transmission. In thi...

This study focused on the molecular characterization and phylogenetic analysis of the EVs and HAVs identified in 33 sewage samples collected every 15  days at the influent of a wastewater treatment plant located in Northern Italy from March to October 2016. According to the results of the molecular characterization, the most frequently identified viruses were Echovirus 6 (E-6), E-11 and HAV-IA. The phylogenetic analyses indicated the rapid genet ic evolution of E-6 and E-1; noteworthy, most E-11 strains clustered with a strain isolated from a clinical sample collected in the same geographical area over the same period...

AbstractWith reports of vancomycin-resistant enterococci recently emerging in hospital settings, renewed focus is turning to the importance of multifaceted infection prevention efforts. Careful compliance with established hygiene practices by healthcare workers together with effective antiseptic options is essential for the protection of patients from infectious agents. For over 60  years, povidone iodine (PVP-I) formulations have been shown to limit the impact and spread of infectious diseases with potent antiviral, antibacterial and antifungal effects. In addition to a lack of reported resistance, the benefits of PV...

AbstractHepatitis C virus (HCV) infection is associated with increased cardiovascular risk. We evaluated effects of direct-acting antiviral agents (DAAs) on flow-mediated dilation (FMD), a recognized marker of cardiovascular risk. We evaluated FMD and post-ischemic hyperemia (PIH) in consecutive HCV out-patients before starting DAAs, at the end of treatment (Teot) and 12  weeks thereafter. In 22 HCV subjects (age 64.0 years), baseline FMD was 4.52% ± 1.90 and PIH of 5814.4 (IQR 3786.9–7861.9). At (Teot), all patients showed undetectable levels of HCV-RNA and FMD changed from 4.52% &thin...
