These data were collected as part of a field trial to test the effectiveness of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available pairs at each location. Baits containing Rhodamine B, a biomarker, were distributed at each plot. At least 1 week and no more than 2 months post-baiting each year, local collaborators captured, marked, and sampled prairie dogs. Hair and whisker samples were collected from up to 50 unique prairie dogs from each plot each year. Sex, age, weight, and the identity of all current-year and prior-year recaptures were recorded for each captured animal. In the laboratory, hair/whiskers were assessed for the presence...
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 developed two new recombinant RCN candidates expressing MoG (RCN-tPA-MoG and RCN-SS-TD-MoG) with the aim of improving RCN-MoG. We assessed and compared in vitro expression, in vivo immunogenicity, and protective efficacy in vaccinated mice challenged intracerebrally with RABV. In this data set, we share results of immunofluorescence assay...

This data set provides biological information from of a captive colony of common vampire bats (wild-caught and born in captivity) that were part of an experimental study on vaccination. It includes results obtained from different assays: RT-PCR, serum neutralization, Rabies direct-fluorescent antibody test, performed periodically during the study (Sep 2018 – May 2020).

In 2013, a large blinded, paired placebo-controlled field trial for the prairie dog oral sylvatic plague vaccine started in the Western US. On 17 paired plots, vaccine and placebo plots, small rodents were trapped annually for 3-5 consecutive nights (when weather allowed). Up on capture, we documented the trap numbers and the processed animals. We noted standard biological information (species, sex, age) and took samples (fleas, blood, hair and whiskers). When logistics allowed we also trapped diurnal animals. Hair and whisker samples were taped to a transparent sheet and scored for the presence (high dose 1, low dose 2) or absence (0) of Rhodamine B fluorescence (RB dataset)
In 2013, a large blinded, paired placebo-controlled field trial for the prairie dog oral sylvatic plague vaccine started in the Western US. On 17 paired plots, vaccine and placebo plots, small rodents were trapped annually for 3-5 consecutive nights (when weather allowed) and high elevation Utah plots where plague was active were more frequently trapped in 2014 and 2015. In the dataset the prevalence of flea infestation was recorded for the first annual summer sampling, it was summarized for all small rodent species caught and deer mice (Peromyscus maniculatus). Infestations were either for all flea species collected or for Aetheca wagneri only (our most abundant flea species). We used this data to assess if plague...
These data were collected as part of a field trial to test the efficacy of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available sites at each location. At least 1 week and no more than 2 months post-baiting each year, local collaborators captured, marked and sampled prairie dogs for a minimum of 3 trap days. Both plots in a pair were trapped on the same day, and trap effort (number of traps and trap days) between plots of the same pair was similar with few exceptions. Fleas were collected from up to 50 unique prairie dogs from each plot each year. Sex, age, weight, and foot length were recorded for each captured animal. In the laboratory,...

Adult AG129 mice (129/Sv background deficient in alpha/beta interferon (IFN-α/β) and IFN-Ɣ receptors) were infected with recombinant Monkeypox virus (MPXV)expressing firefly luciferase by either intranasal (IN) or intraperitoneal (IP) routes. Experimental infections were conducted in a BSL-3 laboratory at the USGS National Wildlife Health Center, with a clade II MPXV that expresses firefly luciferase, as described in Osorio et. al, 2009 (MPXV/USA/luc). Twelve AG129 mice (8 males and 4 females) were infected intranasally with 105 plaque forming units (PFU) (5 ul, each nostril) of MPXV/USA/luc. Three control mice were inoculated in the same manner with an equal volume of PBS. Bioluminescent imaging was performed using...

Monkeypox virus (MPXV) is a zoonotic disease endemic in Central and West Africa and is the most virulent orthopoxvirus affecting humans since the eradication of variola virus (VARV). In order to assess their reservoir potential, wild-caught rope squirrels were experimentally infected via intranasal and intradermal exposure with a recombinant MPXV strain from Central Africa engineered to express the luciferase gene. After infection, we monitored viral replication via in vivo bioluminescent imaging and viral shedding via culture and PCR. MPXV infection in African rope squirrels caused mortality and moderate to severe morbidity, with clinical signs including pox lesions in the skin, eyes, mouth and nose, dyspnea, and...

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 cleared the virus before the end of the study with no obvious clinical signs of disease. We additionally found no evidence of viral transmission to uninoculated subjects. These results indicate that while TABR are susceptible to SARS-CoV-2 infection, infection of wild populations of TABR would not likely cause mortality.

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 possible for 30 s to collect fleas. We recorded the age (juvenile/adult), sex, and mass (nearest 5 g) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent identification. We indexed each prairie dog's body condition as the ratio between its weight and hind-foot...

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.
These data were collected as part of a field trial to test the efficacy of a sylvatic plague vaccine. Treatment and control sites were selected randomly from the available sites at each location. Site pairs were a minimum of 20 acres, (with a few exceptions). Prairie dog trapping took place a minimum of two weeks post-baiting and trapping procedures were approved by the NWHC Animal Care and Use Committee as well as individual states as required.

This data set provides biological information from of a captive study of transgenic mice that received either passive serum transfers from black-footed ferrets (BFFs) that were vaccinated against SARS-CoV-2 or BFFs that were unvaccinated, or a monoclonal antibody against SARS-CoV-2 or lastly a placebo. After these treatments mice were challenged with SARS-CoV-2. The data included here have viral loads in the lungs of treated mice, as well as histological results from various tissues collected at the end of the study.
