Abstract. Cache Valley virus (CVV) and Potosi virus (POTV) are two closely related mosquito-borne viruses (Bunyaviridae: Bunyamwera group) that appear to circulate in several regions of the United States, especially the Midwest. We determined the prevalence of specific neutralizing antibodies to both viruses in Indiana white-tailed deer and conducted infection experiments to assess whether deer could serve as an vertebrate-amplifying host. Crossinfection experiments also were carried out to investigate the level of antibody cross-reactivity and cross-protection between the two viruses. The seroprevalence rate was high for both CVV (Ͼ 66%) and POTV (Ͼ 43%) in adult deer statewide. Antibodies neutralizing CVV were more common among deer harvested in the northern part of Indiana whereas the prevalence of POTV antibodies suggested a more southern distribution for this virus. Experimental infections of captive deer showed that they may serve as amplifying hosts for either virus. Deer infected with CVV or POTV developed a 1-3-day viremia with 3.0 and 4.1 log 10 plaque-forming units/ml mean peak titers, respectively. However, significant levels of antibody cross-reactivity between the two viruses were observed. Viremia was lower and shorter when animals immune to either CVV or POTV were cross-infected with the alternate virus and antibody responses following cross-infections resembled original antigenic sin with higher titers of antibodies against the primary agent.

“…In the literature search, in addition to the epidemic DENV (serotypes 1, 2, 3, and 4), CHIKV and ZIKV, we found reports on experimental infections of Ae. albopictus with the following 36 arboviruses: Arumowot (AMTV) [83], Bujaru (BUJV) [83], Bussuquara (BSQV) [84], Cache Valley (CVV) [85], Chandipura (CHPV) [86], Chilibre (CHIV) [83], Eastern Equine Encephalomyelitis (EEEV) [87][88][89][90], Getah (GETV) [91], Icoaraci (ICOV) [83], Ilheus (ILHV) [92], Itaporanga (ITPV) [83], Jamestown Canyon (JCV) [93], Japanese Encephalitis (JEV) [92,[94][95][96], Karimabad (KARV) [83], Keystone (KEYV) [92,93], Kokobera (KOKV) [92], Kunjin (KUNV) [92], La Crosse (LACV) [92,93,[97][98][99], Mayaro (MAYV) [100], Oropuche (OROV) [100], Orungo (ORUV) [101], Pacui (PACV) [83], Potosi (POTV) [102][103][104], Rift Valley fever (RVFV) [105,106], Ross River (RRV) [107,108], Salehabad (SALV) [83], San Angelo (SA) [84,92,…”

Mosquito-borne arboviruses are increasing due to human disturbances of natural ecosystems and globalization of trade and travel. These anthropic changes may affect mosquito communities by modulating ecological traits that influence the “spill-over” dynamics of zoonotic pathogens, especially at the interface between natural and human environments. Particularly, the global invasion of Aedes albopictus is observed not only across urban and peri-urban settings, but also in newly invaded areas in natural settings. This could foster the interaction of Ae. albopictus with wildlife, including local reservoirs of enzootic arboviruses, with implications for the potential zoonotic transfer of pathogens. To evaluate the potential of Ae. albopictus as a bridge vector of arboviruses between wildlife and humans, we performed a bibliographic search and analysis focusing on three components: (1) The capacity of Ae. albopictus to exploit natural larval breeding sites, (2) the blood-feeding behaviour of Ae. albopictus, and (3) Ae. albopictus’ vector competence for arboviruses. Our analysis confirms the potential of Ae. albopictus as a bridge vector based on its colonization of natural breeding sites in newly invaded areas, its opportunistic feeding behaviour together with the preference for human blood, and the competence to transmit 14 arboviruses.

Durante estudo biológico e ecológico sobre mosquitos levado a cabo em área com registro de epidemia de febre amarela silvestre e epizootia em macacos, foram encontrados adultos de Aedes albopictus. A tendência da espécie para invadir ambiente extradomiciliar potencializa a chance de infecção natural, ao tempo em que evolui para formar um elo entre focos naturais do vírus e o ambiente urbano. Esta Nota Técnica representa um alerta aos gestores dos três poderes públicos sobre perspectivas de mudanças no perfil epidemiológico atual da febre amarela no Brasil.Palavras-chave:febre amarela silvestre; Aedes albopictus; vigilância vetorial.
