Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) pathologist Josué Díaz-Delgago, DVM, MS, PhD, DACVP is part of a team that recently published an article over a novel gammaherpevirus in a free-ranging giant armadillo in Brazil. The novel virus, Cingulatid gammaherpesvirus 1 (CiHV-1), was detected in 3 of the 21 armadillos tested. This instance is the first time this virus was detected in Xenarthra.

The number of viral-associated neoplasms reported in wildlife has increased over the last decades, likely because of growing research efforts and a potentially greater burden of carcinogenic pathogens. Herein, we describe a primary gastric T-cell lymphoma in one free-ranging giant armadillo (Priodontes maximus) from Brazilian Pantanal infected by a novel gammaherpesvirus, proposed as Cingulatid gammaherpesvirus 1 (CiHV-1). By chromogenic in situ hybridisation against Epstein–Barr virus some neoplastic cells were labeled. Subsequently, a molecular screening was carried out to detect the occurrence of this pathogen in other giant armadillos in the same region. Overall, this novel virus was detected in 14.3% (3/21) of the tested giant armadillos. We suggest this herpesvirus, the first in Xenarthra, as a plausible aetiology of the neoplasm. The implications of CiHV-1 for this species are uncertain; while no outbreaks of disease have been recorded, the present study raises concerns. Further research is warranted to assess the real significance of CiHV-1 and its potential oncogenic role in this species.
