Oguzoglu, Huseyin Yilmaz, Juergen A. Richt, Mariette F. DucatezAbstractBovine respiratory infections are the most economically important diseases affecting the cattle industry worldwide including Turkey. Influenza D virus (IDV) could play an important role to trigger bovine respiratory disease (BRD) complex. Since, there is no data about the presence and genotypes of IDV in Turkish cattle herds; this study was performed to investigate IDV in cattle in Turkey. Animals analyzed in this study were from commercial cattle farms having respiratory disease in calves with significant mortality. Nasal swabs and tissue samples from cattle in Marmara, Inner Anatolia and Aegean region of Turkey were analyzed by real-time RT-PCR assay to detect IDV. Among 76 samples form 12 cattle herds, IDV was detected in 3 cattle in a herd. Sequencing and phylogenetic analysis of partial hemagglutinin esterase fusion (HEF) gene showed that the Turkish strain is 95% identical to its European and US counterparts, which suggest intercontinental spread of the virus. These findings highlight the need for future continuous surveillance on larger scale to determine the distribution pattern and evolution of this novel emerging pathogen in Turkish cattle industry.

harine E. Magor RIG-I plays an essential role in the duck innate immune response to influenza infection. RIG-I engages the critical adaptor protein mitochondrial antiviral signaling (MAVS) to activate the downstream signaling pathway. The influenza A virus non-structural protein PB1-F2 interacts with MAVS in human cells to inhibit interferon production. As duck and human MAVS share only 28% amino acid similarity, it is not known whether the influenza virus can similarly inhibit MAVS signaling in avian cells. Using confocal microscopy we show that MAVS and the constitutively active N-terminal end of duck RIG-I (2CARD) c...

AbstractRecently, the novel coronavirus disease 2019 (COVID-19) started spreading in Japan. Therefore, the number of patients with severe COVID-19 requiring extracorporeal membranous oxygenation (ECMO) is expected to increase. A working group has been formed to provide telephone consultation services for cases with severe respiratory failure caused by COVID-19 in Japan. During the first 13  days of the service, there were 12 consultations. For each consultation, we advised the patient on the initiation of ECMO and arranged transportation for patients with ECMO. Based on experience from the H1N1 influenza pandemic, t...

Computational vaccinology includes epitope mapping, antigen selection, and immunogen design using computational tools. Tools that facilitate the in silico prediction of immune response to biothreats, emerging infectious diseases, and cancers can accelerate the design of novel and next generation vaccines and their delivery to the clinic. Over the past 20 years, vaccinologists, bioinformatics experts, and advanced programmers based in Providence, Rhode Island, USA have advanced the development of an integrated toolkit for vaccine design called iVAX, that is secure and user-accessible by internet. This integrated set of immu...

One would hope that it does not require an ongoing pandemic and related hysteria to point out that old people have poorly functioning immune systems, and thus suffer disproportionately the burden of infectious disease. But perhaps it does. The 2017-2018 seasonal influenza, a modestly more severe occurrence of something that happens every year, killed something like 60,000 people in the US alone, with little notice or comment. There is nothing so terrible that it won't be accepted - ignored, even - if it is normal. Floodgates of funding for infectious disease research and development have been opened in response to C...

If there was one glimmer of hope among the alarming number of cases of COVID-19 in the past few months, it was that young children seemed to avoid more serious illness. That trend, which doctors in China first reported, seems to be holding true in the US as well. In the latest Morbidity and Mortality Weekly Report report released today by the Centers for Disease Control (CDC), scientists say that compared to adults, children under the age of 18 are less likely to experience the typical symptoms of infection, including fever, cough and difficulty breathing, and are also less likely to need hospitalization and less likely to...
