A Novel Retrovirus (Gunnison’s Prairie Dog Retrovirus) Associated With Thymic Lymphoma in Gunnison’s Prairie Dogs in Colorado, USA

June 8, 2020 by PDP

 

Abstract

As part of research and wildlife disease surveillance efforts, we performed necropsy examinations of 125 free-ranging (n = 114) and captive (n = 11) prairie dogs in Colorado from 2009 to 2017. From these cases, we identified three cases of thymic lymphoma in free-ranging Gunnison’s prairie dogs (Cynomys gunnisoni), and we identified a novel retroviral sequence associated with these tumors. The viral sequence is 7700 nucleotides in length and exhibits a genetic organization that is consistent with the characteristics of a type D betaretrovirus. The proposed name of this virus is Gunnison’s prairie dog retrovirus (GPDRV). We screened all 125 prairie dogs for the presence of GPDRV using PCR with envelope-specific primers and DNA extracted from spleen samples. Samples were from Gunnison’s prairie dogs (n = 59), black-tailed prairie dogs (Cynomys ludovicianus) (n = 40), and white-tailed prairie dogs (Cynomys leucurus) (n = 26). We identified GPDRV in a total of 7/125 (5.6%) samples including all three of the prairie dogs with thymic lymphoma, as well as spleen from an additional four Gunnison’s prairie dogs with no tumors recognized at necropsy. None of the GPDRV-negative Gunnison’s prairie dogs had thymic lymphomas. We also identified a related, apparently endogenous retroviral sequence in all prairie dog samples. These results suggest that GPDRV infection may lead to development of thymic lymphoma in Gunnison’s prairie dogs.

First genome sequence of the Gunnison’s prairie dog

FIRST PRAIRIE DOG OF 2017 SIGHTED

January 28, 2017 by PDP

An advocate called this morning (1/28) and reported seeing the first prairie dog emerge from hibernation at the NW Corner of Tramway and Lomas (Prairie Hills). This is a bit disturbing as the temperature this morning was 20F possibly warming to 40F later in the day. It is just TOO early. However, we do know that our gunnies can wake up for a snack and then go back into torpor if the weather is cold. We HOPE that’s the case, otherwise it will be a long spring season for our rescue crew. If any of our caregivers are of the mind to visit the lot, could you perhaps drop some carrots or grain down a few of the burrows? Also if you check the areas where you provide supplemental food for PD activity it would be appreciated. Thanks!

 

PS:  The prairie dog pictured  is a black tailed prairie dog in Colorado.

Unintentional cruelty: Are prairie dog relocations worth their mortality?

May 6, 2014 by Ed Urbanski

Spring marks the annual beginning of an increasingly popular non-lethal method of removing 104351404-gunnisons-prairieunwanted prairie dogs: Relocation of entire segments to more suitable and protected habitat.

But the job isn’t for sissies or the faint of heart, because there is a huge amount of work and preparation involved, with a variety of associated challenges, including potentially fatal consequences for a number of prairie dogs—sometimes even if the job is done by experts.

Prairie Dog Daze

May 6, 2014 by Ed Urbanski

Cute is not a reason to go on living in the grander evolutionary scheme of things, but it must count for 40th-Horiz.wideasomething. People love prairie dogs, even if they are next thing to a rat.

Michael Burns never expected to be walking around the plaza dressed in a big, fuzzy, buff-colored costume on the Saturday after Earth Day, hugging children and carrying a cardboard placard that said “Prairie dog family values.” The 36-year-old self-employed salesman who moved to Santa Fe from Portland, Ore. about four years ago, said he never thought much about prairie dogs until recently.
