Fatal tick-borne encephalitis virus infection in Dalmatian puppy-dogs after putative vector independent transmission.

In a retrospective metatranscriptomics study, we identified tick-borne encephalitis virus (TBEV) to be the causative agent for a fatal non-suppurative meningoencephalitis in a three-week-old Dalmatian puppy in Switzerland. Further investigations showed that the two other littermates with similar signs and pathological lesions were also positive for TBEV. By using an unbiased approach of combining high-throughput sequencing (HTS) and bioinformatics we were able to solve the etiology and discover an unusual case of TBEV in three young puppies.

Detection of novel RNA viruses in wild noble crayfish (Astacus astacus): A virome analysis in Swiss water bodies.

European native crayfish populations are undergoing a strong decline due to environmental factors and the introduction of highly competitive non-native species. Pathogens are an additional threat to native crayfish. However, aside from the crayfish plague, other infectious diseases are still widely unknown.

Feline morbillivirus infection associated with fatal encephalitis in a Bengal cat.

Feline morbillivirus (FeMV) is a recently discovered morbillivirus of the family Paramyxoviridae, which include several highly contagious viruses with zoonotic potential. In this case report we describe the detection of FeMV in archived brain tissue of a 2-month-old Bengal cat with nonsuppurative encephalitis from the year 2011 in Switzerland by high-throughput sequencing (HTS). Our metagenomics approach was able to obtain a full-length sequence covering the entire FeMV genome.
