Molecular and Clinical Characterization of Chikungunya Virus Infections in Southeast Mexico

Viruses, 2018
Chikungunya fever is an arthropod-borne infection caused by Chikungunya virus (CHIKV). Even though clinical features of Chikungunya fever in the Mexican population have been described before, there is no detailed information. The aim of this study was to

Development of Vaccines for Chikungunya Fever [PDF]

Journal of Infectious Diseases, 2016
Chikungunya fever, an acute and often chronic arthralgic disease caused by the mosquito-borne chikungunya virus (CHIKV), has reemerged since 2004 to cause millions of cases. Because CHIKV exhibits limited antigenic diversity and is not known to be capable of reinfection, a vaccine could serve to both prevent disease and diminish human amplification ...

Chik Sign: A Clinical Clue to Chikungunya Infection- A Case Series [PDF]

Journal of Clinical and Diagnostic Research
Chikungunya, transmitted by Aedes mosquitoes, manifests with fever, joint pain, and a distinctive cutaneous feature known as the “Chik sign” or “Brownie nose.” The Chik sign is an asymptomatic freckled hyperpigmentation of the tip and ala of the nose and

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, EarlyView.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

IL-1beta, IL-6, and RANTES as biomarkers of Chikungunya severity.

PLoS ONE, 2009
BackgroundLittle is known about the immunopathogenesis of Chikungunya virus. Circulating levels of immune mediators and growth factors were analyzed from patients infected during the first Singaporean Chikungunya fever outbreak in early 2008 to establish

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Effect of a physiotherapy program in patient with persistent polyarthralgia after chikungunya fever. Case report

Revista Dor, 2017
BACKGROUND AND OBJECTIVES: Chikungunya fever is caused by the chikungunya virus, but with characteristics similar to the dengue fever. The main clinical manifestation that differs from dengue is the strong joint pains, which can remain for long periods ...

Beyond the Kidney and Lung: Cutaneous and Mucosal Clues to Human Hantavirus Disease

International Journal of Dermatology, EarlyView.
Rodent exposure and aerosolized excreta can lead to hantavirus infection with systemic endothelial injury and capillary leak, resulting in thrombocytopenia and syndromes such as HPS/HCPS and HFRS/NE. Early dermatologic and mucosal findings, including flushing, conjunctival injection, petechiae/purpura, and mucosal bleeding, may provide important clues ...

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

Insect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).
