Seroprevalence of Alphaviruses (Togaviridae) among Urban Population in Nouakchott, Mauritania, West Africa [PDF]

Viruses, 2023
The presence of alphaviruses, such as chikungunya virus (CHIKV), has never been reported in Mauritania. We assessed the seroprevalence of CHIKV among Nouakchott residents.

Togaviridae [PDF]

Intervirology, 1985
The family Togaviridae comprises four genera: Alphavirus (with 26 species), Rubivirus (one species), Pestivirus (three species), and Arterivirus (one species). The main characteristics of the member viruses are: (i) the virus particles are spherical, 50-70 nm in diameter, including an envelope with surface projections that incorporate two or three ...

Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket-Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target. [PDF]

Adv Sci (Weinh)
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...

Insect-specific viruses: transmission dynamics and biological control strategies against arboviruses [PDF]

Frontiers in Microbiology
Mosquitoes are known to vector arthropod-borne viruses (arboviruses) that pose a global public health issue in the form of mosquito-borne viral diseases such as chikungunya fever, dengue fever, Japanese encephalitis, yellow fever, and Zika.

Group size and nest spacing affect Buggy Creek virus (Togaviridae: Alphavirus) infection in nestling house sparrows. [PDF]

PLoS ONE, 2011
The transmission of parasites and pathogens among vertebrates often depends on host population size, host species diversity, and the extent of crowding among potential hosts, but little is known about how these variables apply to most vector-borne ...

Amphibian Strategies Against Attacks by Flies: Host-Specificity and Threats. [PDF]

Ecol Evol
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...
