High-throughput sequencing has developed into a versatile standard tool in plant virology research. It provides fast and precise genomic data on the viruses being processed for a wide range of applied and basic research questions. This service package offers the individual analysis of three plant samples by HTS to ensure a reliable detection and assembly of the viral genomes.

The service offers to partners a reliable, sensitive and exhaustive technology to detect all viruses infecting plant samples, in particular for the identification of the viruses involved in novel diseases or in syndrome of unknown etiology. The service provides counseling and costing on projects, receives the samples, performs the extraction of nucleic acids. High-throughput sequencing is outsourced to a subcontractor and the platform performs the downstream bioinformatic analysis, up to the identification of known or novel viral agents present in the samples analyzed.

The end-user provided virus (e.g. as a tick homogenate) will be used to experimentally infect castor bean tick nymphs (Ixodes ricinus). The nymphs will be infected by micro-capillary inoculation into the coxal plate of the second pair of legs (transcoxal infection) using a digital microinjector system. First, 100 nymphs will be used for evaluation of the virus replication dynamics. Based on the obtained results, tick-derived virus stock will be generated from an additional 100 nymphs and provided to the end-user.

The end-user provided virus (e.g. as a tick homogenate) will be used to experimentally infect adult castor bean ticks (Ixodes ricinus). The ticks will be infected by micro-capillary inoculation into the coxal plate of the second pair of legs (transcoxal infection) using a digital microinjector system. First, 100 ticks will be used for evaluation of the virus replication dynamics.

Human Immunodeficiency Virus (HIV) drug resistance remains a significant health issue that challenges treatment and prevention. The objective of this 3-week course is to learn bioinformatics techniques for the analysis of next-generation HIV sequencing results. This covers both HIV-1 and HIV-2. Teaching objectives include data curation, alignment, phylogenetics for typing, identification of drug resistance mutations, production of a resistance score, and interpretation. This course does not include genotyping itself, only sequence analysis and interpretation, as described above.

We offer a 5 day training session to colleagues from endemic regions. Participants will visit the Viroscience clinical virology lab, where they will perform all required laboratory and analysis procedures for the quantification rabies virus and neutralizing antibodies.

We would like to invite African researchers to a training workshop on virus diagnostics. In the scope of this three-day workshop, participants from various African countries will acquire hands-on experience in the detection and characterisation of viruses using electron microscopy and Reverse Transcription Polymerase Chain Reaction (RT-PCR). This workshop offers a valuable opportunity for participants to connect and to network with each other, contributing to the prevention of virus outbreaks.

The detection of plant viruses in environmental samples, such as insects, mites, crops, weeds. obtained through high-throughput sequencing (HTS) followed by appropriate bioinformatics analyses, allows to verify the phytosanitary status of plants and is particularly useful for the identification of viruses involved in diseases with unknown etiology. The service offers the individual analysis of three samples by HTS and the downstream bioinformatic analysis, up to the identification of sequences of viral origin in each sample.

This four day course will go through the general principles for the diagnosis of bovine leukemia virus, through a combination of discussions, demonstrations and hands-on training. The training will include sample processing, PCR, ELISA (serology), reagent production, virus related bio-safety and diagnostic quality systems.
