How long MERS-CoV remained viable at high ambient temperature (30°C) and low RH (30 %) ?
[ "Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: A single study has examined the ability of MERS-CoV to survive in the environment . Plastic or steel surfaces were inoculated with 10 6 TCID 50 of MERS-CoV at different temperature and relative humidity and virus recovery was attempted in cell culture. At high ambient temperature and low RH MERS-CoV remained viable for 24 h . By comparison, a well known and efficently transmitted respiratory virus, influenza A virus, could not be recovered in culture beyond four hours under any conditions . Aerosol experiments found MERS-CoV viability only decreased 7 % at low RH at 20°C. In comparison, influenza A", "Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: virus decreased by 95 % . MERS-CoV survival is inferior to that previously demonstrated for SARS-CoV . For context, pathogenic bacteria can remain viable and airborne for 45 min in a coughed aerosol and can spread 4 m. MERS-CoV's ability to remain viable over long time periods gives it the capacity to thoroughly contaminate a room's surfaces when occupied by an infected and symptomatic patient . Whether MERS-CoV can remain adrift and infectious for extended periods remains unknown. Such findings expand our understanding of the possibilities for droplets to transmit respiratory viruses in many settings, including hospital waiting rooms, emergency", "Title: MERS coronavirus: diagnostics, epidemiology and transmission\nPassage: Individual human case studies report long periods of viral shedding, sometimes intermittently and not necessarily linked to the presence of disease symptoms. In one instance, a HCW shed viral RNA for 42 days in the absence of disease . It is an area of high priority to better understand whether such cases are able to infect others. Over three quarters of MERS cases shed viral RNA in their LRT specimens for at least 30 days, while only 30 % of contacts were still shedding RNA in their URT specimens .", "Title: Demographic Variations of MERS-CoV Infection among Suspected and Confirmed Cases: An Epidemiological Analysis of Laboratory-Based Data from Riyadh Regional Laboratory\nPassage: families and healthcare settings .

How were the spread of GFP-expressing virus-infected cells across tissue monolayers tracked via inverted fluorescence microscopy?
[ "Title: Accelerated viral dynamics in bat cell lines, with implications for zoonotic emergence\nPassage: After application of the overlay, plates were monitored periodically using an inverted fluorescence microscope until the first signs of GFP expression were witnessed . From that time forward, a square subset of the center of each well was imaged periodically, using a CellInsight CX5 High Content Screening Platform with a 4X air objective . Microscope settings were held standard across all trials, with exposure time fixed at 0.0006 s for each image. One color channel was imaged, such that images produced show GFP-expressing cells in white and non-GFP-expressing cells in black .", "Title: Accelerated viral dynamics in bat cell lines, with implications for zoonotic emergence\nPassage: Because plaque assays restrict viral transmission neighbor-to-neighbor in two-dimensional cellular space , we were able to track the spread of GFP-expressing virus-infected cells across tissue monolayers via inverted fluorescence microscopy. For each infection trial, we monitored and re-imaged plates for up to 200 hr of observations or until total monolayer destruction, processed resulting images, and generated a time series of the proportion of infectious-cell occupied plate space across the duration of each trial . We used generalized additive models to infer the time course of all cell culture replicates and construct the multi-trial dataset to which we eventually fit our", "Title: Visualizing Viral Infection In Vivo by Multi-Photon Intravital Microscopy\nPassage: express cytoplasmic fluorescent proteins driven e.g., by the chicken β-actin promoter with cytomegalovirus enhancer or human ubiquitin C promoter . Many different mouse lines are available that contain reporter genes for cytoplasmic fluorescent proteins such as EGFP and mCherry . Due to strong and continuous expression rate of the fluorescent proteins long-term tracking of dividing cells without extensive bleaching is possible. In addition, with a superior signal-to-noise ratio visualization of small cellular structures with low cytoplasm content is feasible. Although the approach to adoptively transfer fluorescent cells of interest into donor mice for functional imaging studies is fast and flexible,", "Title: Visualizing Viral Infection In Vivo by Multi-Photon Intravital Microscopy\nPassage: Recently, MP-IVM was used to study the mechanism of retrovirus spread in vivo within secondary lymphoid tissues by visualizing MLV-infected cells and MLV particles directly in living animals. In a first study, in vitro transduced B cells were adoptively transferred into mice for MP-IVM at the popliteal lymph nodes . In contrast to other studies visualizing infected cells expressing cytoplasmic GFP after reporter virus infection, full-length MLV encoding for a capsid fusion with GFP helped to analyze the subcellular distribution of a structural retroviral protein in vivo.

The ELISA-array assay is based on a \"sandwich\" ELISA format and consists of viral antibodies printed directly on 96-well microtiter plates, allowing for direct detection of 5 viruses. The developed ELISA-array proved to have similar specificity and higher sensitivity compared with the conventional ELISAs. This method was validated by different viral cultures and three chicken eggs inoculated with infected patient serum. The results demonstrated that the developed ELISA-array is sensitive and easy to use, which would have potential for clinical use." ]

Are there any vaccines against to protect against respiratory viral infections?
[ "Title: Non-specific Effect of Vaccines: Immediate Protection against Respiratory Syncytial Virus Infection by a Live Attenuated Influenza Vaccine\nPassage: Respiratory viral infections, caused by influenza virus, respiratory syncytial virus , human parainfluenza viruses , and coronaviruses, remain a global public health concern . WHO has acknowledged the magnitude of this problem and has highlighted the need for research focused on the prevention of respiratory viral infections. However, except for influenza virus, there are no authorized vaccines available for the prevention of emerging/re-emerging respiratory viral infections . Vaccination is based on the adaptive immune responses that provide protection against a specific pathogen. Safe and controlled activation of the immune system results in a specific memory in the vaccinated hosts and", "Title: Vaccination against Paediatric Respiratory Pathogens\nPassage: Ongoing studies could identify effective candidates.
