bel Arthropod-borne viruses (arboviruses) of vertebrates including dengue, zika, chikungunya, Rift Valley fever, and blue tongue viruses cause extensive morbidity and mortality in humans, agricultural animals, and wildlife across the globe. As obligate intercellular pathogens, arboviruses must be well adapted to the cellular and molecular environment of both their arthropod (invertebrate) and vertebrate hosts, which are vastly different due to hundreds of millions of years of separate evolution. Here we discuss the comparative pressures on arbovirus RNA genomes as a result of a dual host life cycle, focusing on pressur...

Authors: Kim YH, Kim TY, Park JS, Park JS, Lee J, Moon J, Chong CK, Junior IN, Ferry FR, Ahn HJ, Bhatt L, Nam HW Abstract A rapid diagnostic test (RDT) kit was developed to detect non-structural protein 1 (NS1) of yellow fever virus (YFV) using monoclonal antibody. NS1 protein was purified from the cultured YFV and used to immunize mice. Monoclonal antibody to NS1 was selected and conjugated with colloidal gold to produce the YFV NS1 RDT kit. The YFV RDTs were evaluated for sensitivity and specificity using positive and negative samples of monkeys from Brazil and negative human blood samples from Korea. Among monoc...

Publication date: Available online 29 May 2019Source: International Journal of Pediatrics and Adolescent MedicineAuthor(s): Tracy Evans-GilbertAbstractChikungunya (CHIKV), Zika (ZIKV), and Dengue viruses (DENV) exhibit similar epidemiological and clinical patterns but have different pathophysiological mechanisms of disease manifestations. Differences occur in the severity of clinical presentations with the highest mortality in the general population attributed to DENV and neurological morbidity due to ZIKV. ZIKV and DENV infections can cause fetal loss with ZIKV exhibiting teratogenesis. CHIKV is associated with severe com...

Authors: Lee H, Ryu JH, Park HS, Park KH, Bae H, Yun S, Choi AR, Cho SY, Park C, Lee DG, Lim J, Lee J, Lee S, Shin S, Park H, Oh EJ Abstract ELISAs and rapid diagnostic tests (RDTs) are widely used for diagnosing dengue virus (DENV) infection. Using 138 single blood samples, we compared the ability to detect non-structural (NS)-1 antigen and anti-DENV IgM/IgG antibodies among (1) DENV Detect NS1 ELISA, DENV Detect IgM capture ELISA and DENV Detect IgG ELISA (InBios International, Inc.); (2) Anti-Dengue virus IgM Human ELISA and Anti-Dengue virus IgG Human ELISA (Abcam); (3) Dengue virus NS1 ELISA, Anti-Dengue virus...

de;o Maria de Fátima Vanderlei de Souza Helicteres velutina K. Schum (Sterculiaceae), a member of Malvaceae sensu lato, is a Brazilian endemic plant that has been used by the indigenous tribe Pankarare as an insect repellent. A previous study has reported the isolation of terpenoids, flavonoids and pheophytins, in addition to the larvicidal activity of crude H. velutina extracts derived from the aerial components (leaves, branches/twigs, and flowers). The present study reports the biomonitoring of the effects of fractions and isolated compounds derived from H. velutina against A. aegypti fourth instar larvae. ...

e;o G Abstract Guillain-Barre syndrome (GBS) is one of the main neurologic manifestations of arboviruses, especially Zika virus infection. As known, the prevalence of these diseases is high, so the risk of having an increase on GBS is relevant. The study purposes making a comparative survey between the involvement of dengue, Zika and chikungunya infections in the development of the GBS in Brazil, as well as search in literature resemblances and distinctions between beforehand reported cases. It was performed an electronic search in online databases, with articles published between the years of 2004 to 2018. A tota...

by Spencer J. Fox, Steven E. Bellan, T. Alex Perkins, Michael A. Johansson, Lauren Ancel Meyers As emerging and re-emerging infectious arboviruses like dengue, chikungunya, and Zika threaten new populations worldwide, officials scramble to assess local severity and transmissibility, with little to no epidemiological history to draw upon. Indirect estimates of risk from vector habitat suitabi lity maps are prone to great uncertainty, while direct estimates from epidemiological data are only possible after cases accumulate and, given environmental constraints on arbovirus transmission, cannot be widely generalized beyond th...
