TWiV 567: Outbreaks and a breakout

The TWiV team covers outbreaks of eastern equine encephalitis virus in the US and poliovirus in the Philippines, and explain how a chemokine induced by HIV-1 infection helps release more virus particles from cells.

Abstract Newcastle disease virus (NDV) remains a constant threat to the poultry industry even with intensive vaccination programmes. In the present study, 40 samples were collected from farms showing high mortalities in some Egyptian governorates between 2016 and 2018. Tracheal samples were collected for virus isolation and confirmed by real-time RT-PCR. Molecular characterisation was performed by sequencing, followed by phylogenetic analysis of the novel sequences. Histopathological and immunohistochemical examinations were performed on different organs from NDV-infected broilers. The phylogenetic analysis reveal...

CONCLUSIONS: This study revealed the disease burden due to mumps and its complications in Japan during 2005-2017. These data suggest the need for mumps-prevention measures in adolescents and adults, as well as in children. PMID: 32684528 [PubMed - as supplied by publisher]

PLYMOUTH (CBS) – Massachusetts Gov. Charlie Baker said the state is expecting another summer with a high number of cases of Eastern Equine Encephalitis (EEE). Baker spoke about EEE preparations during a press conference Tuesday in Plymouth. “Every few years there are outbreaks with a higher number of cases,” said Baker. “We saw one of those just last summer. During the 2019 season, there were 12 human cases of EEE and six people died from those infections. It’s important to keep in mind that EEE outbreaks typically last two or three years. That means that we can expect the 2020 season to featu...

The claimed invention relates to viable chimeric dengue viruses or their derived recombinant mutants for use as vaccines against dengue and other flavivirus diseases, including tick-borne encephalitis and West Nile encephalitis. Dengue is a mosquito-transmitted viral disease which occurs in tropical and subtropical regions throughout the world. Inactivated whole dengue virus vaccines have been shown to be insufficiently immunogenic and live dengue virus vaccines prepared by serial passage in cell culture have not been shown to be consistently attenuated. A dengue vaccine is still not available. The present invention repres...

n Chu Over the course of the last 50 years, the emergence of several arboviruses have resulted in countless outbreaks globally. With a high proportion of infections occurring in tropical and subtropical regions where arthropods tend to be abundant, Asia in particular is a region that is heavily affected by arboviral diseases caused by dengue, Japanese encephalitis, West Nile, Zika, and chikungunya viruses. Major gaps in protection against the most significant emerging arboviruses remains as there are currently no antivirals available, and vaccines are only available for some. A potential source of antiviral compounds c...

AbstractThe Japanese encephalitis virus (JEV) is one of the vector borne causes of encephalitis found in southeastern Asia. This positive single-stranded RNA virus is a member of the Flaviviridae family, which notably includes dengue, tick-borne, West Nile, Zika as well as yellow fever, and transmits to humans by infected mosquitos. The main site of interactions for antibodies against this virus is the envelope protein domain III (ED3). The present report investigates the time-dependent structural and conformational changes of JEV ED3 functional epitopes and escape mutants by computer simulations. The results indicate the ...

Conclusions: This study demonstrates that the vaccination schedule should be reevaluated. The extension of the interval of booster immunization is risky and all subjects should be surrounded by care consisting of more frequent monitoring of serum antibodies by personalized schedule to adjust the frequency of subsequent doses of booster vaccination.

Conclusions. The two peptides TVYHCSAVY and FLIDRINWI have showed a very strong binding affinity to MHC class I and MHC class II alleles. Furthermore, considering the conservancy, the affinity, and the population coverage, the peptide FLIDRINWIT is highly suitable to be utilized to formulate a new vaccine against glycoprotein G of Nipah henipavirus. An in vivo study for the proposed peptides is also highly recommended. PMID: 32377531 [PubMed - in process]

Arboviruses (arthropod-borne) are a group of viruses that encompass hundreds of members and span multiple viral families making it one of the most genetically diverse, widespread, and dangerous groups of viruses on earth. Arboviruses are transmitted to humans by a variety of geographically widespread arthropod vectors (most commonly, mosquitoes and ticks) so that these viruses can change location with human hosts or arthropod vectors, with potential for rapid spread wherever these vectors are present. Past outbreaks of West Nile virus and recent outbreaks of eastern equine encephalitis virus, Zika virus, and chikungunya vi...
