Chikungunya virus vector competency of Brazilian and Florida mosquito vectors

PLOS Neglected Tropical Diseases, 2018
Chikungunya virus is a vector-borne alphavirus transmitted by the bites of infected female Ae. aegypti and Ae. albopictus. In Brazil between 2014 and 2016 almost 320 thousand autochthonous human cases were reported and in Florida numerous imported CHIKV viremic cases (> 3,800) demonstrate the potential high risk to establishment of local transmission ...

COMPARATIVE GENOMICS OF VECTOR AND NON-VECTOR INSECTS: UNCOVERING MOLECULAR DETERMINANTS OF VECTOR COMPETENCE [PDF]

Acta Scientifica Malaysia
Vector competence is the inherent capacity of an insect to transmit diseases to plants and other organisms. It’s a complex feature influenced by several factors such as their physiology, microbiology, environment and some genetic factors.

Zika virus outbreak in the Pacific: Vector competence of regional vectors

PLOS Neglected Tropical Diseases, 2018
In 2013, Zika virus (ZIKV) emerged in French Polynesia and spread through the Pacific region between 2013 and 2017. Several potential Aedes mosquitoes may have contributed to the ZIKV transmission including Aedes aegypti, the main arbovirus vector in the region, and Aedes polynesiensis, vector of lymphatic filariasis and secondary vector of dengue ...

Experimental infection and vector competence of Zika virus in Aedes aegypti mosquitoes from Acapulco, Guerrero, Mexico

Salud Pública de México, 2020
Objective. To gain a better understanding of the Zika virus (ZIKV) vector transmission in Mexico, we determined the vector competence of a local population of Ae. aegypti (Aca­pulco, Guerrero) for a strain of ZIKV isolated from a Mexican febrile patient.

Vector competence of Aedes vexans (Meigen), Culex poicilipes (Theobald) and Cx. quinquefasciatus Say from Senegal for West and East African lineages of Rift Valley fever virus [PDF]

, 2016
Background Rift Valley fever virus (RVFV; Phlebovirus, Bunyaviridae) is a mosquito–borne, zoonotic pathogen. In Senegal, RVFV was first isolated in 1974 from Aedes dalzieli (Theobald) and thereafter from Ae. fowleri (de Charmoy), Ae. ochraceus Theobald,

Entomological assessment of dengue virus transmission risk in three urban areas of Kenya.

PLoS Neglected Tropical Diseases, 2019
Urbanization is one of the major drivers of dengue epidemics globally. In Kenya, an intriguing pattern of urban dengue virus epidemics has been documented in which recurrent epidemics are reported from the coastal city of Mombasa, whereas no outbreaks ...

Identifying Knowledge Gaps through the Systematic Review of Temperature-Driven Variability in the Competence of Aedes aegypti and Ae. albopictus for Chikungunya Virus

Pathogens, 2023
Temperature is a well-known effector of several transmission factors of mosquito-borne viruses, including within mosquito dynamics. These dynamics are often characterized by vector competence and the extrinsic incubation period (EIP).

Aedes aegypti vector competence studies: A review

Infection, Genetics and Evolution, 2019
Aedes aegypti is the primary transmitter of the four viruses that have had the greatest impact on human health, the viruses causing yellow fever, dengue fever, chikungunya, and Zika fever. Because this mosquito is easy to rear in the laboratory and these viruses grow in laboratory tissue culture cells, many studies have been performed testing the ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Analysis of switching dynamics with competing support vector machines [PDF]

Proceedings of the 2002 International Joint Conference on Neural Networks. IJCNN'02 (Cat. No.02CH37290), 2003
We present a framework for the unsupervised segmentation of switching dynamics using support vector machines. Following the architecture by Pawelzik et al., where annealed competing neural networks were used to segment a nonstationary time series, in this paper, we exploit the use of support vector machines, a well-known learning technique.
