Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Viruses is an international peer-reviewed Open Access monthly journal published by MDPI.

Formaldehyde (FA) inactivation of infectious agents is well established in the field of diagnostic electron microscopy of viruses. However, published experimental data that directly prove inactivation by the procedures used are lacking. Usually, inactivation is performed more or less directly before preparation of the samples for microscopy is taking place. The process must transform viruses in a non-infectious but structurally intact form to allow a proper diagnosis based on morphology. FA provides an essential advantage in comparison to other disinfectants, because it preserves the ultrastructure of biological material without interfering significantly with the preparation protocol (i.e. the negative staining). To check the efficiency of FA inactivation we have used vaccinia virus, adenovirus and murine norovirus as models and treated them with different protocols using formaldehyde. Critical factors for the inactivation efficiency were concentration of the FA, duration and temperature of the treatment as well as the complexity of the virus. Our results show that inactivation at low temperature (4 to 8°C) is not sufficient regardless of its duration and that increasing the temperature (up to 37° C) is completing and shortening the inactivation process which improves both biosafety and speed of diagnostic electron microscopy.

Title: Membranous Replication Factories Induced by Plus-strand RNA Viruses

In this review we summarize the current knowledge about the membranous replication organelles of members of the family Flaviviridae. Electron tomography studies of cells infected with viruses belonging to the genus Flavivirus revealed the formation of ER membrane invaginations. However Hepatitis C Virus -genus Hepacivirus- induces the formation of double membrane vesicles (DMVs), which are extrusions also originating from ER membranes. DMVs are not only the hallmark of HCV infection, but also induced by other (+) strand RNA viruses like coronaviruses, arteriviruses, picornaviruses and caliciviruses, indicating that these distantly related viruses might utilize common host cell pathways for replication.
