Vector-Borne Diseases

Vector-borne diseases are transmitted from one animal to another by vectors, including insects, such as mosquitoes or fleas, and arachnids, such as ticks. The USGS National Wildlife Health Center investigates wildlife diseases, including vector-borne diseases, such as West Nile virus and sylvatic plague.

Experimental infection of Mexican free-tailed bats (Tadarida brasiliensis) with SARS-CoV-2 Experimental infection of Mexican free-tailed bats (Tadarida brasiliensis) with SARS-CoV-2

We experimentally challenged wild Mexican free-tailed bats (TABR) with SARS-CoV-2 to determine the susceptibility, reservoir potential, and population impacts of infection in this species. Of nine bats oronasally inoculated with SARS-CoV-2, five became infected and orally excreted moderate amounts of virus for up to 18 days post inoculation. These five subjects all seroconverted and...

In vitro expression, immunogenicity, and efficacy data from recombinant raccoon poxvirus-vectored rabies vaccine candidates tested in mice In vitro expression, immunogenicity, and efficacy data from recombinant raccoon poxvirus-vectored rabies vaccine candidates tested in mice

This work is part of an experimental trial to develop and assess novel recombinant raccoonpox virus (RCN) rabies vaccines in the mouse model, for potential use in bats. Briefly, our research group previously developed a recombinant RCN vaccine candidate expressing a mosaic glycoprotein (MoG) gene that protected mice and big brown bats when challenged with rabies virus (RABV). We...

Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016 Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016

Data on flea parasitism and annual re-encounters of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies along an elevation gradient from 2,645 m to 2,873 m. Upon first capture each year, we anesthetized each prairie dog and fleas on its body and combed the prairie dog as thoroughly as...

Fleas collected from black-tailed prairie dog burrows in 2016 and 2017 Fleas collected from black-tailed prairie dog burrows in 2016 and 2017

The data are a list of the number and species of fleas that were collected from black-tailed prairie dog burrows in Montana, North Dakota, South Dakota, Colorado, and New Mexico. Fleas were collected by swabbing ~100 burrows at 3 sites at each of 6 sites. Burrows were sampled twice each summer during 2016 and 2017.

Incorporating environmental heterogeneity and observation effort to predict host distribution and viral spillover from a bat reservoir Incorporating environmental heterogeneity and observation effort to predict host distribution and viral spillover from a bat reservoir

Predicting the spatial occurrence of wildlife is a major challenge for ecology and management. In Latin America, limited knowledge of the number and locations of vampire bat roosts precludes informed allocation of measures intended to prevent rabies spillover to humans and livestock. We inferred the spatial distribution of vampire bat roosts while accounting for observation effort and

Management of vampire bats and rabies: Past, present, and future Management of vampire bats and rabies: Past, present, and future

Rabies virus transmitted via the bite of common vampire bats (Desmodus rotundus) has surpassed canine-associated cases as the predominant cause of human rabies in Latin America. Cattle, the preferred prey of D. rotundus, suffer extensive mortality from vampire bat associated rabies, with annual financial losses estimated in the tens of millions of dollars. Organized attempts to manage or...

Monkeypox virus in animals: Current knowledge of viral transmission and pathogenesis in wild animal reservoirs and captive animal models Monkeypox virus in animals: Current knowledge of viral transmission and pathogenesis in wild animal reservoirs and captive animal models

Mpox, formerly called monkeypox, is now the most serious orthopoxvirus (OPXV) infection in humans. This zoonotic disease has been gradually re-emerging in humans with an increasing frequency of cases found in endemic areas, as well as an escalating frequency and size of epidemics outside of endemic areas in Africa. Currently, the largest known mpox epidemic is spreading throughout the...

Sex-biased infections scale to population impacts for an emerging wildlife disease Sex-biased infections scale to population impacts for an emerging wildlife disease

Demographic factors are fundamental in shaping infectious disease dynamics. Aspects of populations that create structure, like age and sex, can affect patterns of transmission, infection intensity and population outcomes. However, studies rarely link these processes from individual to population-scale effects. Moreover, the mechanisms underlying demographic differences in disease are...

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus is thought to have originated in wild bats from Asia, and as the resulting pandemic continues into its third year, concerns have been raised that the virus will expand its host range and infect North American wildlife species, including bats. Mexican free-tailed bats (Tadarida brasiliensis) live in large colonies in...
