Cellular resistance to arbovirus infection.
When an arbovirus enters an arthropod in an infected blood meal, several mechanisms may interact to affect its life cycle and ultimate transmissibility. Intrinsic absolute failure in the establishment of infection must be contrasted with infection that is successfully established but is variably modulated in its viral yield throughout the vector's life-span. Degrees of vertebrate host resistanc...
متن کاملEpidemiology of Rotavirus Infection in Certain Countries
Abstract Acute diarrhea with severe dehydration has been a major worldwide cause of death in children younger than 5 years of age. Etiological studies of gastroenteritis have shown that rotavirus causes 40–50% of acute diarrhea among infants and children in both developing and developed nations. Numerous epidemiologic studies in the US and the World Health Organization have docu...
متن کاملArbovirus infection increases with group size.
Buggy Creek (BCR) virus is an arthropod-borne alphavirus that is naturally transmitted to its vertebrate host the cliff swallow (Petrochelidon pyrrhonota) by an invertebrate vector, namely the cimicid swallow bug (Oeciacus vicarius). We examined how the prevalence of the virus varied with the group size of both its vector and host. The study was conducted in southwestern Nebraska where cliff sw...
متن کاملTissue Barriers to Arbovirus Infection in Mosquitoes
Arthropod-borne viruses (arboviruses) circulate in nature between arthropod vectors and vertebrate hosts. Arboviruses often cause devastating diseases in vertebrate hosts, but they typically do not cause significant pathology in their arthropod vectors. Following oral acquisition of a viremic bloodmeal from a vertebrate host, the arbovirus disease cycle requires replication in the cellular envi...
متن کاملTaking a bite out of nutrition and arbovirus infection.
Nutrition is a key factor in host-pathogen defense. Malnutrition can increase both host susceptibility and severity of infection through a number of pathways, and infection itself can promote nutritional deterioration and further susceptibility. Nutritional status can also strongly influence response to vaccination or therapeutic pharmaceuticals. Arthropod-borne viruses (arboviruses) have a lon...
