The Impact

Histiocytic sarcomas refer to highly aggressive tumors with a poor prognosis that respond poorly to conventional treatment approaches. Oncolytic viruses, which have gained significant traction as a cancer therapy in recent decades, represent a promising option for treating histiocytic sarcomas through their replication and/or by modulating the tumor microenvironment. The live attenuated canine distemper virus (CDV) vaccine strain Onderstepoort represents an attractive candidate for oncolytic viral therapy. In the present study, oncolytic virotherapy with CDV was used to investigate the impact of this virus infection on tumor cell growth through direct oncolytic effects or by virus-mediated modulation of the tumor microenvironment with special emphasis on angiogenesis, expression of selected MMPs and TIMP-1 and tumor-associated macrophages in a murine xenograft model of canine histiocytic sarcoma. Treatment of mice with xenotransplanted canine histiocytic sarcomas using CDV induced overt retardation in tumor progression accompanied by necrosis of neoplastic cells, increased numbers of intratumoral macrophages, reduced angiogenesis and modulation of the expression of MMPs and TIMP-1. The present data suggest that CDV inhibits tumor growth in a multifactorial way, including direct cell lysis and reduction of angiogenesis and modulation of MMPs and their inhibitor TIMP-1, providing further support for the concept of its role in oncolytic therapies.

Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.

An outbreak of canine distemper virus in a private zoo in eastern Tennessee in July 2016 led to fatal clinical disease in 5 adult, wild-caught Linnaeus’s 2-toed sloths ( Choloepus didactylus). Clinical signs included hyporexia, lethargy, mucopurulent nasal discharge, and oral and facial ulcers. At necropsy, affected animals had crusts and ulcers on the lips, nose, tongue, and oral cavity. Microscopically, all sloths had widespread, random, hepatic necrosis; lymphoid depletion; and bronchointerstitial pneumonia. The central nervous system did not contain gross or histopathologic lesions in any of the 5 sloths, although immunoreactivity for viral antigen was present within vessel walls. Epithelial cells and histiocytes within numerous organs contained intranuclear and intracytoplasmic inclusions and occasional syncytial cells. Canine distemper virus was confirmed with immunohistochemistry and virus isolation. Viral sequencing identified the novel American-4 strain prevalent in eastern Tennessee wildlife. This is the first pathologic characterization of canine distemper virus infection in sloths (family Choloepodidae, order Pilosa) and emphasizes the significant morbidity and mortality in this species.

SummaryAn analysis of hypertrophic osteodystrophy (HOD), craniomandibular osteopathy (CMO) and canine distemper virus (CDV) infection was undertaken. Risk factors (age, breed, sex, neuter status, weight, geographical and seasonal distribution) of the three diseases were determined and compared. Patient records were searched using the Veterinary Medical Database (VMDB) during the period of 1980 through 1989. This search identified 131 cases of HOD, 68 cases of CMO and 1,757 of CDV infection. Dogs less than six months of age were identified to be at greatest risk for HOD, CMO and CDV. The Great Dane, Cairn Terrier and the Greyhound were identified to be at highest risk for HOD, CMO and CDV infection, respectively. Males puppies were twice as likely to develop HOD. We concluded, from the risk factors analyzed, that risk factors for HOD, CMO or CDV infection were not similar.Patient information was obtained from clinical cases of 16 veterinary teaching hospitals to examine a possible relationship between Hypertrophic Osteodystrophy (HOD), Craniomandibular Osteopathy (CMO), and Canine Distemper Virus (CDV) infections. Risk factors for each disease were determined. Subjective comparison of risk factors for HOD and CMO did not support the notion of a relationship between HOD and CMO. In addition, no evidence for a possible relationship between CDV and HOD or CMO was found.
