Journal ArticleDOI
Characterization of a New Epidemic Necrotic Pyoderma in Fur Animals and Its Association with Arcanobacterium phocae Infection
Heli Nordgren,Kirsi Aaltonen,Tarja Sironen,Paula M. Kinnunen,Ilkka Kivistö,Mirja Raunio-Saarnisto,Anna-Maria Moisander-Jylhä,Johanna Korpela,Ulla-Maija Kokkonen,Udo Hetzel,Antti Sukura,Olli Vapalahti +11 more
TL;DR: The results obtained from this study implicate A. phocae as a potential causative pathogen of fur animal epidemic necrotic pyoderma (FENP) and support observations that the epidemic may have originated in a species -shift of the causative agent from marine mammals.

Snake deltavirus utilizes envelope proteins of different viruses to generate infectious particles
Leonora Szirovicza,Udo Hetzel,Udo Hetzel,Anja Kipar,Anja Kipar,Luis Martinez-Sobrido,Olli Vapalahti,Jussi Hepojoki,Jussi Hepojoki +8 more
TL;DR: These findings indicate that deltaviruses can likely use a multitude of helper viruses or even viral glycoproteins to form infectious particles, and it seems plausible that new human and veterinary disease associations with delTavirus infections will be identified in the future.
Journal ArticleDOI
Prevalence and protein specificity of human antibodies to Inkoo virus infection.
TL;DR: A diagnostic IgG IFA pattern distinguishing between acute infection and long-standing immunity was observed, and N protein seems to be the optimal antigen for the serodiagnosis of acute infection, and the Gc protein could be appropriate for theserosurveillance of INKV.
Journal ArticleDOI
Scent dogs in detection of COVID-19: triple-blinded randomised trial and operational real-life screening in airport setting
Anu Kantele,Juuso Paajanen,Soile Turunen,Sari H. Pakkanen,Anu Patjas,Laura Itkonen,Elina Heiskanen,Maija Lappalainen,Loïc Desquilbet,Olli Vapalahti,Anna Hielm-Björkman +10 more
TL;DR: This large randomised controlled triple-blinded validation study with a precalculated sample size conducted at an international airport showed that trained scent dogs screen airport passenger samples with high accuracy, highlighting the importance of continuous retraining as new variants emerge.
Journal ArticleDOI
The Virome of Acute Respiratory Diseases in Individuals at Risk of Zoonotic Infections.

TL;DR: More frequent detections of the novel viruses by PCR than by mNGS on the same samples suggests that PCR remains the most sensitive diagnostic test for viruses whose genomes are known.
