Agglutination of an Arbovirus by Concanavalin A
Nature New Biology, 1971MANY enveloped viruses contain carbohydrates as components of glycoproteins1–5 or glycolipid6. We have found (unpublished results) that the envelope of Semliki Forest virus (SFV), a group A arbovirus, contains a glycoprotein in which the principal sugars are mannose, galactose and N-acetylglucos-amine and also a glucose-containing glycolipid.

Acta Pediatrica De Mexico, 2016 Las enfermedades producidas por arbovirus son un problema muy grave a nivel mundial, debido a que su vigilancia y prevención implica también la vigilancia de sus vectores, lo que hace difícil su control y casi imposible evitar su expansión a cualquier país tropical o subtropical, e incluso algunas regiones templadas.

Arbovirus Antibodies in Avian Sera
Nature, 1966SEVERAL arboviruses are known to infect wild and domestic birds and the possibility that migratory birds may act as disseminators of arboviruses has been investigated in America and Asia1,2. During the spring of 1965, samples of blood were collected by members of the West Sahara Ornithological Expedition from birds netted at the Defilia Oasis, near ...

Arbovirus infections in travellers
Journal of Infection, 1979Summary Seventeen of 64 military personnel with previous tropical experience possessed antibodies to a group B arbovirus; of 35 similar personnel with no previous overseas experience, none possessed antibodies.

Developing arbovirus resistance in mosquitoes
Insect Biochemistry and Molecular Biology, 2002Diseases caused by arthropod-borne viruses are increasingly significant public health problems, and novel methods are needed to control pathogen transmission. The hypothesis underlying the research described here is that genetic manipulation of Aedes aegypti mosquitoes can profoundly and permanently reduce their competence to transmit dengue viruses to

Arboviruses (arthropod-borne viruses), though taxonomically diverse, share a cycle of transmission between vertebrate hosts and arthropod vectors. All but one arbovirus species belong to one of five families of RNA viruses, suggesting that the high mutation frequencies of RNA genomes may be a prerequisite for entry into a cycle of alternating ...

Yellow Fever Despite the existence of an effective vaccine for yellow fever, there are still almost 80,000 fatalities from this infection each year. Since 2016, there has been a resurgence of cases in Africa and South America—and this at a time when the vaccine is in short supply.

Nineteen arboviruses have been isolated in Canada, including 11 mosquito-transmitted, 6 tick-transmitted and 2 culicoides-transmitted viruses. Only 6 of these viruses have been documented to have caused symptomatic infections in humans in Canada—western equine encephalitis, St.

Pathogenesis of Neurotropic Arbovirus Infections
1968Ever since arbovirus infections became known and their relative importance assessed, experiments were designed to elucidate the mode of transmission and the most important natural hosts responsible for perpetuating the infection in nature. Human infections and the disease in wild rodents, birds, and domestic animals were studied in relation to viremia ...
