Animal shelters provide an ideal environment for the spread of disease. Dogs are often housed in close quarters with others of unknown vaccine histories, and experience high levels of sustained stress. As a result, Canine Infection Respiratory Disease (CIRD) is often prevalent and difficult to control. The aims of this study were to (1) identify specific pathogens responsible for CIRD in a city shelter in West Texas, USA, and (2) determine whether intake vaccinations decrease proportion of dogs exhibiting signs of CIRD even during an outbreak. A laboratory analysis of conjunctival, pharyngeal, and nasal swabs (n = 15 dogs) and fecal samples (n = 6 kennels) showed prevalence of various CIRD pathogens (e.g., canine adenovirus-2, canine parainfluenza virus, canine distemper virus). All fifteen dogs tested positive for at least one pathogen, with the most prevalent pathogen being Canine Distemper Virus (CDV; n = 12). All of the kennels (n=6) tested positive for Canine Distemper Virus. Health data on dogs (n = 1,258) over the age of 6 weeks were assessed from May to August 2017. Beginning in July, both stray and owner-surrendered dogs were vaccinated with Nobivac® Canine 1-DAPPv 5 Way and Nobivac® Intra-Trac® 3 upon intake, which differed from the previous policy. For each day in the study, we calculated the proportion of dogs in each nasal discharge category, the proportion of dogs observed coughing, and the mean fecal score across all dogs. We conducted a linear regression between the proportion of the shelter vaccinated and the proportion of dogs coughing. At the beginning of the vaccination phase, ~25% of the dogs were coughing. However, as the proportion of the dogs vaccinated increased, the proportion of dogs coughing decreased. There was a significant decrease of 7% of the proportion of dogs coughing when vaccination was at least at 90% compared to when it was <90%. These data suggest that the shelter in this study was experiencing a CIRD outbreak, with CDV being primary pathogen, and that it is possible to substantially reduce illness by implementing a vaccination on intake protocol. The current study provides support for the importance of vaccination in animal shelter welfare.

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.

Currently, there are no reliable predictors of the clinical outcomes of domesticated dogs that have been recently vaccinated against canine distemper virus (CDV) and develop respiratory disease. In this study, vaccinated dogs from Oklahoma City that were showing clinical signs of respiratory disease were evaluated for CDV antigen using a direct fluorescent antibody test (FAT). Clinical outcomes after standard symptomatic therapy for respiratory disease were recorded, and a statistical analysis of the results was performed. We present our study showing that CDV FAT results were predictive of clinical recovery (prognostic indicator, prospects of clinical recovery) among vaccinated dogs showing clinical signs of respiratory disease. Negative CDV FAT results equated to 80% chances of recovery after symptomatic therapy, compared to 55% chances of recovery when the CDV FAT results were positive. Based on the results of this study, we show that veterinarians can make better informed decisions about the clinical outcomes of suspected CDV cases, with 2-h turnaround times, by using the CDV FAT. Thus, antemortem examination with the CDV FAT on external epithelia of recently vaccinated, sick dogs is a clinically useful diagnostic test and valuable prognostic indicator for veterinarians. Application of the CDV FAT to these samples avoids unnecessary euthanasia of dogs with suspected CDV.

Aims: This study aimed to determine the Canine Distemper Virus (CDV) lineage circulating in the Puducherry region (Southern India) and how they are genetically and antigenically related to the vaccine and other known CDV lineages around the world. Study Design: The study involved genetic characterization of the canine distemper virus strains/lineages circulating in the clinically suspected dogs in the field. Place and Duration of Study: Department of Veterinary Clinical Complex, Animal Husbandry Department, Private Veterinary Clinics, NGOs like Bark India, People for Animals organization, Puducherry between January 2018 and December 2019. Methodology: The ocular and nasal swabs were collected from 40 dogs suspected for canine distemper from Puducherry state (Southern India). Following viral RNA Extraction and cDNA synthesis; the cDNAs were screened for virus by targeting the CDV Nucleocapsid (N) gene using Reverse Transcriptase PCR. Further, the N gene positive cDNAs were genetically characterized for sequence analysis of the CDV hemagglutinin (H) gene. Results: A total of 15 (37.5%) out of 40 ocular/ nasal swabs were found to be CDV positive by RT-PCR targeting the N gene. The sequence analysis of the H gene revealed forty-nine non-synonymous and thirty-three synonymous mutations (out of 356 amino acids) in comparison with vaccine strain. The vaccine virus (Onderstepoort strain), which is related to the America 1 lineage, possessed high level of (30 – 35 i.e. more than 10%) amino acid divergence with the CDV sequences analysed in this study. The Phylogenetic analysis revealed that the present CDV sequences formed a separate monophyletic group with the CDV sequences of other Indian dogs and the Indian wildlife (Lion) and is clustered away from the vaccine strain. The CDV sequences were closer to the CDVs of Africa - 2 lineage than the other Asian lineages.  The Recombination analysis revealed no potential breakpoints and recombination events. Conclusion: Together, these findings highlighted the possible existence of the novel Indian CDV lineage/s distinct from the vaccine strain and from other known Asian lineages.

Abstract Background: Canine Distemper is infectious, highly contagious viral disease of canine and feline species with worldwide occurrence, having characteristics of systemic signs with frequent nervous dysfunction. However, the previous studies have underreported canine distemper status in Ethiopia together with its strain makes this study mandatory. Therefore, the principal aim of the present study was to find out the occurrence of CD from clinical dogs in association with other cases in Addis Ababa pet clinics. Results: Out of the 150 dogs that are brought to different Addis Ababa pet clinics, 70 cases (46.66%) were identified to have signs suggestive of CDV infection. Of all the 70 suspected cases of CD, ocular and nasal discharge swab samples were collected and screened by FASTest DISTEMPER Strip kit test for the presence of canine distemper virus. Of the screened samples, 16 (22.86%) were positive for canine distemper. Samples that were positive for FASTest DISTEMPER Strip kit test were further confirmed using cell culture in Vero cell as gold standard technique. Out of the 16 screened positive samples inoculated in Vero cells, 12 specimen (75%) showed Cytopathic effects (CPE) in the form of Syncytia formation within 24 and 48 hours of inoculation while the rest 4 negative samples were passaged in Vero cell three times before declaring negative. Uninoculated negative controls included in each run did not show any effects. Conclusion: The present study revealed the existence of CD in the study area, showing 16 positive domestic dogs out of 70 cases do not received periodic immunization according to CD strains. Besides this, CD is chief disease of local domestic dogs relative to exotic breed. Therefore isolation of clinical domestic dogs from healthy ones, good management practice, public awareness creation about the disease, routine immunization of animals according to circulating strains of CD is mandatory.

Canine distemper virus (CDV) is a major viral pathogen in domestic dogs, belonging to the Paramyxoviridae family, in the Morbillivirus genus. It is present worldwide, and a wide range of domestic animals and wild carnivores are at risk. In the absence of vaccination, dogs have a low chance of survival; however, if and when a dog survives, it can take an average of a few weeks to a few months to fully wipe out the virus. In the present study, we traced the course of infection of a 1-year-old mixed-breed male dog. The animal had an unusually long course of persistent CDV infection with a vector-borne heartworm (Dirofilaria immitis) co-infection. The dog excreted the CDV for 17 months with PCR positivity in urine samples collected from February 2019 through June 2020. The sequencing and phylogenetic analysis of the hemagglutinin gene revealed the CDV to be the member of the endemic Arctic-like genetic lineage. To the best of our knowledge, this report represents the longest documented canine infection of CDV. Notably, we highlight the necessity regarding CDV infectivity studies to better comprehend the transmission attributes of the virus.

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.
