Virological and serological surveys have documented that H1N1/2009, avian-origin canine H3N2 (cH3N2), seasonal human-origin H3N2 (hH3N2), and equine-origin H3N8 influenza viruses are consistently circulating in dogs. In the present study, a multiplex reverse-transcriptase polymerase chain reaction (mRT-PCR) assay was developed for simultaneous detection and differentiation of these influenza viruses. Four primer sets were designed to target the hemagglutinin genes of H1N1/2009, cH3N2, hH3N2, and H3N8 canine influenza viruses (CIVs)...

Whole exome sequencing (WES) has become a common tool for identifying genetic causes of human inherited disorders, and it has also recently been applied to canine genome research. We conducted WES analysis of neuroaxonal dystrophy (NAD), a neurodegenerative disease that sporadically occurs worldwide in Papillon dogs. The disease is considered an autosomal recessive monogenic disease, which is histopathologically characterized by severe axonal swelling, known as "spheroids," throughout the nervous system. By sequencing all eleven DNA samples from one NAD-affected Papillon dog and her parents, two unrelated NAD-affected Papillon dogs, and six unaffected control Papillon dogs, we identified 10 candidate mutations...

The Norwegian Lundehund is a highly endangered native dog breed. Low fertility and high frequency predisposition to intestinal disorder imply inbreeding depression. We assessed the genetic diversity of the Lundehund population from pedigree data and evaluated the potential of optimal contribution selection and cross-breeding in the long-term management of the Lundehund population. The current Norwegian Lundehund population is highly inbred and has lost 38.8% of the genetic diversity in the base population. Effective population size estimates varied between 13 and 82 depending on the method used...

The grey wolf (Canis lupus) is one of the most widely distributed terrestrial mammals, and its distribution and ecology in Europe and North America are largely well described. However, the distribution of grey wolf in southern China is still highly controversial. Several well-known western literatures stated that there are no grey wolves in southern China, while the presence of grey wolf across China has been indicated in A Guide to the Mammals of China, published by Princeton University Press. It is essential to solve this discrepancy since dogs may have originated from grey wolfs in southern China...

The International Agency for Research on Cancer (IARC) has classified two liver flukes as carcinogenic to humans (Group 1): Opisthorchis viverrini in 1994 and Clonorchis sinensis in 2009. This review is focused on O. viverrini, the most studied of these two trematodes, which infects nearly 10 million people in Southeast Asia. The life cycle involves two intermediate hosts living in fresh water: a snail of the genus Bithynia and a ciprinid fish. The definitive hosts (human, cat, dog) become infected by ingesting raw fish containing metacercariae, the infective stage of the parasite...

Secretomes in the conditioned media from human mesenchymal stem cells (MSC-CM) were previously demonstrated to promote periodontal tissue regeneration. By mixing insulin-like growth factor-1, vascular endothelial growth factor-A, and transforming growth factor-β1 which were included in MSC-CM, we made the cytokine cocktail (CC) mimicking MSC-CM, and then evaluated its efficacy on periodontal tissue regeneration. In vitro, CC promoted the migration of dog bone marrow-derived stem cells and periodontal ligament cells, and the tube formation of human umbilical vein endothelial cells...

Cryopreservation affects integrity of cholesterol and phospholipids in the plasma membrane of sperm leading to decreased fertility of frozen-thawed semen. Cholesterol-loaded cyclodextrins (CLC) have been shown to improve post-thaw semen quality in various species. The aim of this study was to investigate the optimal concentration of CLC for better post-thaw semen quality in dogs. Semen collection, through digital manipulation, was conducted once a week in four adult German shepherd dogs (n = 20 ejaculates; five ejaculates/dog)...

Leptin (Lep) and insulin-like growth factor 1 (IGF1) are implicated in the regulation of testicular function, but in dogs, our knowledge is limited to the possible role of the IGF1 system in testicular tumours. In this study, we aimed to describe and compare gene expression and protein localization of Lep, IGF1 and their receptors (LepR and IGF1R, respectively) in the testis of healthy adult and prepubertal dogs. Testes were collected from sexually healthy mature (n = 7) and from 8-week-old dogs (n = 7)...

BACKGROUND: In humans, reduced activity of the enzyme monoamine oxidase type A (MAOA) due to genetic polymorphisms within the MAOA gene leads to increased brain neurotransmitter levels associated with aggression. In order to study MAOA genetic diversity in dogs, we designed a preliminary study whose objectives were to identify novel alleles in functionally important regions of the canine MAOA gene, and to investigate whether the frequencies of these polymorphisms varied between five broad breed groups (ancient, herding, mastiff, modern European, and mountain)...

The recommendation to treat canine lymphoma with a discontinuous protocol is based on small case numbers and mostly historic controls. This study compares duration of first remission (DFR) and overall survival time (ST) with a discontinuous protocol to the same protocol with maintenance phase. 408 dogs were treated with a CHOP-LAsp (C=cyclophosphamide; H=hydroxydaunorubicin; O=Oncovin; P=prednisolone; LAsp=l-asparaginase)-based 28-week induction protocol. In 75 dogs (cohort 1), this was followed by a maintenance phase consisting of vincristine, chlorambucil and actinomycin-D with a total treatment duration of two years...

Muscle shortening and volume displacement are critical determinants of the pressure generating capacity of the diaphragm. This study was designed to test the hypothesis that diaphragm volume displacement is heterogeneous and distribution of volume displacement is dependent on regional muscle shortening, posture and level of muscle activation. Radio opaque markers were sutured along muscle bundles of the peritoneal surface of the crural muscle, dorsal costal, mid-costal, and ventral costal regions of the left hemi-diaphragm in four dogs...

BACKGROUND: Food allergies are increasing in prevalence but no treatment strategies are currently available to cure dogs with food allergy. Over the past decade, experimental food allergen-specific sublingual immunotherapy (FA-SLIT) has emerged as a potential treatment for food allergies in human medicine. However, FA-SLIT has not been investigated in dogs. Therefore, the objective of this study was to prospectively evaluate the safety, tolerability and dispenser sterility of FA-SLIT in healthy dogs before testing it in food allergic dogs...

Histiocytic ulcerative colitis (HUC) is a chronic enteropathy which most notably occurs in Boxer dogs and French bulldogs. The inflamed mucosa is hallmarked by large, foamy, periodic acid-Schiff (PAS)-positive macrophages infiltrating the colonic mucosa. As little is known about their origin and phenotype, an immunohistochemical study was performed using different macrophage markers. Generally, canine colonic macrophages showed high expression of ionised calcium-binding adaptor molecule 1 and MHC class II. In canine HUC, macrophages revealed up-regulation of lysozyme and L1 Ag but decreased CD163 expression compared with controls, suggesting them to be pro-inflammatory cells, whereas the healthy colonic mucosa was characterised by an anti-inflammatory macrophage phenotype...

As a result of the 2011 nuclear incident that occurred at the Fukushima Nuclear Power Plant, a large number of abandoned dogs and cats were left within the disaster zone. A small number of these animals were rescued and cared for at shelters. Prior to the dispersal of these animals to their owners or fosterers, we evaluated the degree of internal radiocesium contamination using a specially designed whole-body counter. We conducted 863 non-invasive measurements of gamma rays due to internal radioactive cesium for 68 dogs and 120 cats at one shelter...
