“…Their uses are closely connected to their unique structural features which allow ions to be readily exchanged and/or that different active species be temporary or permanent immobilized inside the porous aluminosilicate framework. Recently, various natural and synthetic zeolites have been extensively studied as promising materials for hosting ions with antimicrobial activity [5][6][7]. The antimicrobial activity usually involves the slow release of antimicrobial metal ions (such as Cu 2+ , Zn 2+ or Ag + ) from the zeolite lattice and the inactivation of some pathogenic viruses has been ascribed to metal ion held by aluminosilicate lattice [6].…”

“…EM revealed that the morphology of purified 8KS0813 viral particles resembles that of members of the subfamily Paramyxoviridae [3,7]. The majority of 8KS0813 particles were spherical in size, ranging from about 140 to 350 nm in diameter, and pleomorphic shapes were also observed ( Supplementary Fig.…”

A hemagglutinating virus (8KS0813) was isolated from a red-necked stint. Hemagglutination inhibition and neutralization tests indicated that 8KS0813 was antigenically related to a prototype strain, APMV-6/duck/Hong Kong/18/199/77, but with an 8-and 16-fold difference, respectively, in their titers. The full genome sequence of 8KS0813 showed 98.6 % nucleotide sequence identity to that of APMV-6/duck/Italy/4524-2/07, which has been reported to belong to an APMV-6 subgroup, and showed less similarity to that of the prototype strain (70.6 % similarity). The growth of 8KS0813 and the prototype strain in four different cell cultures was greatly enhanced by adding trypsin. Interestingly, this virus induced syncytia only in Vero cells. 8KS0813 was identified as APMV-6/rednecked stint/Japan/8KS0813/08, but it is antigenically and genetically distinguishable from the prototype strain, suggesting that variant APMV-6 is circulating in migratory birds.Paramyxoviruses are pleomorphic enveloped viruses containing a non-segmented ssRNA genome that replicate in the cytoplasm of host cells. Members of a great variety of mammalian and avian species can be infected with these viruses [12]. Paramyxoviruses isolated from birds are divided into two distinct groups: avian paramyxovirus (APMV) and avian metapneumovirus. APMVs belong to the genus Avulavirus of the subfamily Paramyxoviridae and are divided into nine serotypes, from APMV-1 to -9 [1]. Recently, viruses of three new serotypes, APMV-10, APMV-11 and APMV-12, were isolated from rockhopper penguins, common snipes and wigeons, respectively [2,10,17]. Subgrouping within the APMV serotype has also been Electronic supplementary material The online version of this article

“…The use of wipes coated with antimicrobials may allow combined cleaning and disinfection of surfaces and prevent crosscontamination via the cleaning cloth if the pathogen is inactivated efficiently in the cloth. Cloths that incorporate antimicrobials such as light-activated polymers or copper-based biocides have been shown to be efficient in inactivating pathogens (36)(37)(38)(39)(40).…”

bTransmission of enteric and respiratory viruses, including human norovirus (hNoV) and human influenza virus, may involve surfaces. In food preparation and health care settings, surfaces are cleaned with wipes; however, wiping may not efficiently reduce contamination or may even spread viruses, increasing a potential public health risk. The virucidal properties of wipes with a singlet-oxygen-generating immobilized photosensitizer (IPS) coating were compared to those of similar but uncoated wipes (non-IPS) and of commonly used viscose wipes. Wipes were spiked with hNoV GI.4 and GII.4, murine norovirus 1 (MNV-1), human adenovirus type 5 (hAdV-5), and influenza virus H1N1 to study viral persistence. We also determined residual and transferred virus proportions on steel carriers after successively wiping a contaminated and an uncontaminated steel carrier. On IPS wipes only, influenza viruses were promptly inactivated with a 5-log 10 reduction. D values of infectious MNV-1 and hAdV-5 were 8.7 and 7.0 h on IPS wipes, 11.6 and 9.3 h on non-IPS wipes, and 10.2 and 8.2 h on viscose wipes, respectively. Independently of the type of wipe, dry cleaning removed, or drastically reduced, initial spot contamination of hNoV on surfaces. All wipes transferred hNoV to an uncontaminated carrier; however, the risk of continued transmission by reuse of wipes after 6 and 24 h was limited for all viruses. We conclude that cleaning wet spots with dry wipes efficiently reduced spot contamination on surfaces but that cross-contamination with noroviruses by wiping may result in an increased public health risk at high initial virus loads. For influenza virus, IPS wipes present an efficient one-step procedure for cleaning and disinfecting contaminated surfaces.
