The surface modification of the silica-coated magnetic nanoparticles and their application in molecular diagnostics of virus infection.

The study presents a series of examples of magnetic nanoparticle systems designed for the diagnosis of viral diseases. In this interdisciplinary work, we describe one of the most comprehensive synthetic approaches for the preparation and functionalization of smart nanoparticle systems for rapid and effective RT-PCR diagnostics and isolation of viral RNA. Twelve different organic ligands and inorganic porous silica were used for surface functionalization of the FeO magnetic core to increase the number of active centres for efficient RNA binding from human swab samples.

The role of molecular-genetic techniques in BVDV eradication in Lower Austria.

A voluntary bovine viral diarrhoea virus (BVDV) control programme, which later became a compulsory eradication programme, based on the Swedish model was introduced in Lower Austria in 1997. The persistently infected animals were detected by Ag-ELISA and all samples were re-tested by the improved single-tube RT-PCR, employing panpestivirus primers targeting the 5'-UTR of the virus genome. In 2010, the BVDV eradication programme, which became compulsory from 2004, reached the final stage with only five remaining infected herds in which BVDV was difficult to eradicate.

Analysis of RNA virome in rectal swabs of healthy and diarrheic pigs of different age.

The porcine enteric virome comprises a wide range of eukaryotic and prokaryotic viruses in healthy and diarrheic pigs. As RNA viruses are considered to be important agents responsible for diarrhoea in pigs, this work was focused on the RNA virome. To identify viruses, a next generation sequencing technique and bioinformatics analysis was employed.

Overview of Cattle Diseases Listed Under Category C, D or E in the Animal Health Law for Which Control Programmes Are in Place Within Europe.

The COST action "Standardising output-based surveillance to control non-regulated diseases of cattle in the European Union (SOUND control)," aims to harmonise the results of surveillance and control programmes (CPs) for non-EU regulated cattle diseases to facilitate safe trade and improve overall control of cattle infectious diseases. In this paper we aimed to provide an overview on the diversity of control for these diseases in Europe. A non-EU regulated cattle disease was defined as an infectious disease of cattle with no or limited control at EU level, which is not included in the European Union Animal health law Categories A or B under Commission Implementing Regulation (EU) 2020/2002.
