Investigation of protective level of rabies antibodies in vaccinated dogs in Chennai, India.

Vet Rec Open 2021 Dec 5;8(1):e8. Epub 2021 Apr 5.

Division of Genetics and Genomics The Roslin Institute and The Royal (Dick) School of Veterinary Studies The University of Edinburgh, Midlothian UK.

Background: Rabies is still endemic in India causing an estimated 20,000 human deaths a year. Free roaming dogs and unvaccinated owned dogs play a major role in the maintenance of the disease. Dog vaccination is the most crucial aspect of rabies prevention and control strategies; therefore vaccine immunogenicity and longevity are important determinants of the efficiency of rabies control efforts.

Cerebellar projections to the macaque midbrain tegmentum: Possible near response connections.

Vis Neurosci 2021 May 12;38:E007. Epub 2021 May 12.

Department of Neurobiology and Anatomical Sciences, University of Mississippi Medical Center, Jackson, Mississippi.

Since most gaze shifts are to targets that lie at a different distance from the viewer than the current target, gaze changes commonly require a change in the angle between the eyes. As part of this response, lens curvature must also be adjusted with respect to target distance by the ciliary muscle. It has been suggested that projections by the cerebellar fastigial and posterior interposed nuclei to the supraoculomotor area (SOA), which lies immediately dorsal to the oculomotor nucleus and contains near response neurons, support this behavior.

Phylogenetic analysis of nucleoprotein gene of Rabies virus in Malaysia from 2015 to 2018.

Trop Biomed 2021 Jun;38(2):72-78

Veterinary Research Institute, 59, Jalan Sultan Azlan Shah, 31400 Ipoh, Perak, Malaysia.

Rabies is a fatal zoonotic disease caused by rabies virus (RABV) and remains a public health problem in Malaysia. Malaysia was declared rabies-free in 2012, however rabies outbreaks occurred at few states in Peninsular Malaysia three years later; and for the first time, in Sarawak (East Malaysia) in 2017 which has caused more than 20 human deaths. This study describes the phylogenetic analysis of the complete nucleoprotein (N) gene of RABV from animal samples in Malaysia from year 2015 to 2018. Read More

Rabies-infected dogs at slaughterhouses: A potential risk of rabies transmission via dog trading and butchering activities in Vietnam.

Zoonoses Public Health 2021 May 10. Epub 2021 May 10.

Hanoi Center for Disease Control, Hanoi, Vietnam.

The study aimed to determine the status of neutralizing antibodies and rabies virus infection in dogs at slaughterhouses in Hanoi city from 2015 to 2017. A total of 2,376 pairs of blood and brain samples were collected from dogs at 92 slaughterhouses (8 large slaughterhouses and 84 small slaughterhouses) in 6 districts in Hanoi. Of the 1,500 dog samples from the large slaughterhouses where imported dogs were slaughtered, no dog brain samples were infected with rabies virus and no blood samples were positive for rabies neutralizing antibodies.

The ecological niche of reported rabies cases in Canada is similar to Alaska.

Zoonoses Public Health 2021 May 6. Epub 2021 May 6.

Department of Veterinary Medicine, University of Alaska, Fairbanks, AK, USA.

The ecology of rabies in the circumpolar North is still not well understood. We use machine learning, a geographic information system and data explicit in time and space obtained for reported rabies cases and predictors in Canada to develop an ecological niche model for the distribution of reported rabies cases in the American north (Alaska and Canada). The ecological niche model based on reported rabies cases in Canada predicted reported rabies cases in Alaska, suggesting a rather robust inference and even similar drivers on a continental scale.

Reactive oxygen species as potential antiviral targets.

Rev Med Virol 2021 May 4. Epub 2021 May 4.

Department of Microbiology and Biochemistry, University of the Free State, Bloemfontein, South Africa.

Reactive oxygen species (ROS) are by-products of cellular metabolism and can be either beneficial, at low levels, or deleterious, at high levels, to the cell. It is known that several viral infections can increase oxidative stress, which is mainly facilitated by viral-induced imbalances in the antioxidant defence mechanisms of the cell. While the exact role of ROS in certain viral infections (adenovirus and dengue virus) remains unknown, other viruses can use ROS for enhancement of pathogenesis (SARS coronavirus and rabies virus) or replication (rhinovirus, West Nile virus and vesicular stomatitis virus) or both (hepatitis C virus, human immunodeficiency virus and influenza virus).

Genetic identification of a rabies virus from an insectivorous bat in an urban area of Rio Grande do Sul, Brazil.

Braz J Microbiol 2021 May 4. Epub 2021 May 4.

Departamento de Medicina Veterinária Preventiva, Centro de Ciências Rurais, Universidade Federal de Santa Maria, Av. Roraima, 1000, Santa Maria, Rio Grande do Sul, 97105-900, Brazil.

In Latin America, hematophagous bats are the main reservoirs of rabies virus (RABV) to livestock, to other mammals and, occasionally, to human. Nonetheless, reports of exposure of human and pets to RABV upon aggression by non-hematophagous bats are increasing, possibly facilitated by the synanthropic habits of these bats. We, herein, report the detection and genetic identification of a RABV recovered from an insectivorous bat found sick in a student housing building at the Federal University of Santa Maria, Southern Brazil.

Whole-Brain Mapping the Direct Inputs of Dorsal and Ventral CA1 Projection Neurons.

Front Neural Circuits 2021 14;15:643230. Epub 2021 Apr 14.

Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology, Wuhan, China.

The CA1, an important subregion of the hippocampus, is anatomically and functionally heterogeneous in the dorsal and ventral hippocampus. Here, to dissect the distinctions between the dorsal (dCA1) and ventral CA1 (vCA1) in anatomical connections, we systematically analyzed the direct inputs to dCA1 and vCA1 projection neurons (PNs) with the rabies virus-mediated retrograde trans-monosynaptic tracing system in Thy1-Cre mice. Our mapping results revealed that the input proportions and distributions of dCA1 and vCA1 PNs varied significantly. Read More

Department of Infectious, Tropical Diseases & Microbiology (DITM), IRCCS Sacro Cuore Don Calabria Hospital, Negrar di Valpolicella, Verona, Italy. Electronic address:

Rabies is a vaccine preventable zoonotic disease with a significant mortality burden worldwide. Several years of vaccination campaigns in wildlife animals have now achieved the control of rabies in Western Europe through a vaccination belt in front of endemic Eastern European countries. Nevertheless, rabies could be imported both by travellers from areas without an active public control of the disease or by animals coming from areas where the virus circulates in wildlife fauna.

siRNA Loaded-Exosomes.

Methods Mol Biol 2021 ;2282:395-401

Laboratory of Molecular Neurobiology, Center for Biomedical Research of La Rioja (CIBIR), Logroño, Spain.

Exosomes are membrane-bound vesicles (40-100 nm) of endocytic origin released by numerous cell types that act as natural carriers of mRNA, microRNA, and proteins between cells. We developed a new system that uses intravenous injection of modified exosomes for siRNA delivery into the brain. Here we describe the generation of unmodified and modified exosomes, which specifically target the brain, and the method to load siRNA into the exosomes. Read More

Full-Genome Sequences and Phylogenetic Analysis of Archived Danish European Bat Lyssavirus 1 (EBLV-1) Emphasize a Higher Genetic Resolution and Spatial Segregation for Sublineage 1a.

Viruses 2021 04 7;13(4). Epub 2021 Apr 7.

Institute of Molecular Virology and Cell Biology, Friedrich-Loeffler-Institut (FLI), WHO Collaborating Centre for Rabies Surveillance and Research, OIE Reference Laboratory for Rabies, 17493 Greifswald-Insel Riems, Germany.

European bat lyssavirus type 1 (EBLV-1) is the causative agent for almost all reported rabies cases found in European bats. In recent years, increasing numbers of available EBLV-1 full genomes and their phylogenetic analyses helped to further elucidate the distribution and genetic characteristics of EBLV-1 and its two subtypes, namely EBLV-1a and EBLV-1b. Nonetheless, the absence of full-genome sequences from regions with known detections of EBLV-1 still limit the understanding of the phylogeographic relations between viruses from different European regions.
