Adverse reactions to vaccines were examined in 311 canine cases reported to the Ministry of Agriculture, Forestry and Fisheries in Japan during the period of 6 years from April of 1994 to March of 2000, and classified according to their clinical symptoms. There were 27 cases of adverse reactions to rabies virus vaccines. Gastrointestinal symptoms were the most frequently observed (26%), followed by respiratory and/or cardiovascular symptoms (22%) and dermatologic symptoms (11%). There were 284 cases of adverse reactions to non-rabies monovalent vaccines and mixed vaccines. Dermatologic symptoms were the most frequently observed (53%), followed by gastrointestinal symptoms (16%) and respiratory and/or cardiovascular symptoms (14%). Of the total 311 cases, 11 (3.5%) died of adverse reactions to vaccines.

Gammaherpesviruses (GHVs) are members of an emerging subfamily of the family Herpesviridae. A recent study identified a novel GHV in domestic cats (Felis catus GHV1, FcaGHV1), and epidemiological surveys have found that FcaGHV1 is distributed worldwide. In this study, we investigated the prevalence of GHVs in domestic cats in Japan with a molecular epidemiological survey. Blood samples were collected from 1,738 domestic cats and GHV-derived DNA was detected with PCR in 1.3% (23/1,738) of the Japanese domestic cats. The FcaGHV1 detected in this study was very similar to FcaGHV1 detected in a domestic cat in North America. Older age (>5 years old) and Feline immunodeficiency virus infection were identified as risk factors for GHV infection.

Following an outbreak of classical swine fever (CSF) in Japan, 2018, CSFV JPN/1/2018 was isolated from an infected pig sample. In this study, we carried out a comparative experimental infection in pigs using this strain and the highly virulent ALD strain and compared outcomes, including clinical manifestation, virus shedding patterns and antibody responses. Although pigs inoculated orally or intramuscularly with JPN/1/2018 developed hyperthermia and had decreased leucocyte numbers, they survived for the whole experimental period and showed less severe clinical signs than those infected with the ALD strain. We confirmed the presence of characteristic multifocal infarction of the margin of the spleen that arises following infection with JPN/1/2018, albeit that this finding was not observed in all infected pigs. Both viruses efficiently spread to contact pigs in a similar manner, suggesting in transmissibility between the two strains. Viral RNAs were detected in all clinical samples, especially whole blood samples, before the pigs developed hyperthermia until at least approximately 2 weeks after inoculation. Our findings will be valuable for the investigations into epidemic events occurring in Japan and for establishing diagnostic strategies and control measures against CSF.

We utilized autoradiography to visualize radioactive contamination in the skeletal muscles of a pig raised within 20 km of the Fukushima Daiichi nuclear power plant following the nuclear accident. The autoradiogram of control muscle showed relatively homogenous exposure. In contrast, the autoradiogram of affected muscle showed a heterogeneous and sporadically dense imaging pattern. Photo luminescence densities of the affected and control muscles were 3.89 ± 0.67 and 2.13 ± 0.43 PSL/mm2, respectively. This difference indicated that radioactive cesium was distributed in the skeletal muscle of the affected pig.

着床期の犬子宮内膜に人工的刺激を加えると, 脱落膜反応が誘起できることを先の報告で明らかにしたが, これらの組織反応は刺激の種類によって相違した. 本報告では,オリーブオイルを刺激源にしたときの組織反応の特徴を明らかにする目的でオリーブオイル注入のみの場合と創傷刺激後に注入した場合の組織像を比較検討した. 前者の場合は,子宮内膜上皮は網状あるいは樹枝状に子宮内腔に向け増殖したが, 機能層並びに基底層子宮腺の豪胞状過形成は起こらなかった. これに対して後者の場合は子宮内膜上皮の増殖以外に創傷性損傷を受けたと思われる箇所を中心にして基底腺の嚢胞状拡張増殖が付加され, いわゆるスイスチーズ様内膜を示した. オリーブオイルのみの刺激で子宮内膜上皮並びに緻密層子宮腺の子宮内腔へ向けての増殖を誘発することができるが, 機能層や基底層の子宮腺の増殖拡張を引き起こすには子宮腺の開口部の損傷が必要である.

The transgenerational maintenance of symbiotic microbes that benefit host nutrition and health is evolutionarily advantageous. In some vertebrate lineages, coprophagy is used as a strategy for effectively transmitting microbes across generations. However, this strategy has still not been studied in birds. Accordingly, the aim of the present study was to evaluate the role of maternal cecal feces consumption by Japanese rock ptarmigan (Lagopus muta japonica) chicks as a strategy for acquiring essential gut microbes. Both the duration of coprophagy behavior by the chicks and the development process of the chick cecal microbiome (n=20 one- to three-week-old chicks, from three broods) were investigated. In all three broods, coprophagy behavior was only observed from 3 to 18 days of age. Furthermore, there was no significant difference in the number of bacterial operational taxonomic units (OTUs) in 1-week-old chicks (n=651) and adults (n=609), and most of the main OTUs observed in the adults were already present in the 1-week-old chicks. These results indicate that, in this precocial bird species, coprophagy may contribute to the early establishment of cecal bacteria that are essential for food digestion and, thus, chick survival. In fact, Japanese rock ptarmigan chicks consume the same food as their hens from the time of hatching. This behavior may have applications to ex-situ conservation.

The intestinal microbiota was revealed with the recent advances in molecular techniques, such as high-throughput sequencing analysis. As a result, the microbial changes are thought to influence the health of humans and animals and such changes are affected by several factors including diet, genetics, age, sex, and diseases. Similar studies are being conducted in dogs, and the knowledge of intestinal microbiota in dogs is expanding. Nonetheless, basic information on intestinal microbiota in dogs is less than that of humans. Our aim was to study toy poodles (n=21), a popular companion dog, in terms of basic characteristics of the faecal microbiota by 16S rRNA gene barcoding analysis. In the faecal microbiota, Firmicutes, Bacteroidetes, Proteobacteria, and Fusobacteria were the dominant phyla (over 93.4% of faecal microbiota) regardless of the attributes of the dogs. In family level, Enterobacteriaceae, Bacteroidaceae, and Lachnospiraceae were most prevalent. In case of a dog with protein-losing enteropathy, the diversity of faecal microbiota was different between before and after treatment. This study provides basic information for studying on faecal microbiota in toy poodles.

The lesser mouse deer (Tragulus javanicus) is one of the most primitive ruminants. Skulls of lesser mouse deer were measured to evaluate their growth. The age was estimated from the eruption and attrition of molars on the mandible. A total of 95 specimens was divided into five age groups, and the growth pattern in each sex was established for some measurements. The relative growth coefficients were calculated for the head and body length and several parts of the cranium and mandible against the profile length. Sexual dimorphism could not be found on the skull in any age group except for measurements related to the upper canine. However, females showed a higher value in head and body length in the oldest group. This feature was consistent with an interpretation of mouse deer society as monogamous. Growth was more rapid in length than in width. Various statistical analyses showed that the visceral cranium related to masticatory facility was much better developed than the neurocranium. However, observations on the shape of the mandible ramus and of the premolars implied that the masticatory function was not suitable for taking roughage. This speculation agreed with previous reports on the feeding habits and digestive organs of the mouse deer.

Malignant melanoma is one of the most common and aggressive tumors in the oral cavity of dog. The tumor has a poor prognosis, and methods for diagnosis and prediction of prognosis after treatment are required. Here, we examined metabolite profiling using gas chromatography-mass spectrometry (GC-MS) for development of a discriminant model for evaluation of prognosis. Metabolite profiles were evaluated in healthy and melanoma plasma samples using orthogonal projection to latent structure using discriminant analysis (OPLS-DA). Cases that were predicted to be healthy using the OPLS discriminant model had no advanced lesions after radiation therapy. These results indicate that metabolite profiling may be useful in diagnosis and prediction of prognosis of canine malignant melanoma.

Neonicotinoids, some of the most widely used pesticides in the world, act as agonists to the nicotinic acetylcholine receptors (nAChRs) of insects, resulting in death from abnormal excitability. Neonicotinoids unexpectedly became a major topic as a compelling cause of honeybee colony collapse disorder, which is damaging crop production that requires pollination worldwide. Mammal nAChRs appear to have a certain affinity for neonicotinoids with lower levels than those of insects; there is thus rising concern about unpredictable adverse effects of neonicotinoids on vertebrates. We hypothesized that the effects of neonicotinoids would be enhanced under a chronic stressed condition, which is known to alter the expression of targets of neonicotinoids, i.e., neuronal nAChRs. We performed immunohistochemical and behavioral analyses in male mice actively administered a neonicotinoid, clothianidin (CTD; 0, 10, 50 and 250 mg/kg/day), for 4 weeks under an unpredictable chronic stress procedure. Vacuolated seminiferous epithelia and a decrease in the immunoreactivity of the antioxidant enzyme glutathione peroxidase 4 were observed in the testes of the CTD+stress mice. In an open field test, although the locomotor activities were not affected, the anxiety-like behaviors of the mice were elevated by both CTD and stress. The present study demonstrates that the behavioral and reproductive effects of CTD become more serious in combination with environmental stress, which may reflect our actual situation of multiple exposure.

DNA methylation is an epigenetic mechanism controlling gene expression without affecting DNA sequences, and aberrant DNA methylation patterns are features of a number of diseases. Notably, epigenetic errors in cancer cells have been intensively studied over the last two decades in humans; however, little is known concerning dogs and cats. To analyze DNA methylation and gene expression changes in feline lymphoma cells, we added the DNA methylation inhibitor 5-aza-2′-deoxycytidine (5-aza) to three cell lines (3281 and FT-1 cells derived from T-cell lymphoma and MS4 cells derived from B-cell lymphoma). Adding 5-aza significantly retarded cell growth in a dose-dependent manner in all cell lines, and there were aberrant gene expression patterns. Transcription factor Sox11 expression in 3281 cells was de-repressed by 5-aza treatment, and subsequent promoter DNA demethylation was analyzed by bisulfite sequencing. Cell cycle analysis suggested that inhibition of cell growth was due to DNA replication arrest, and this supported the result of increased expression of p27kip1 gene which disturbed cells of 3281 and FT-1 entering the S phase. In this study, 5-aza suppressed the growth of feline lymphoma cells, but further experiments with normal lymph cells are necessary to confirm specificity of this drug treatment and to expand it for clinical use.

Canine histiocytic sarcoma (HS) is a rare neoplasm that originates from dendritic cells or macrophages, and there have been a number of cases experienced in Japan. To identify the characteristics and prognostic variables that determine outcome in dogs with HS in Japan, medical records of 73 dogs with HS were retrospectively analyzed. Signalment, clinical signs, complete blood count (CBC), blood chemistry profiles, treatment, response to treatment and overall survival (OS) were analyzed. Diagnosis of HS was determined histologically in 44 cases and cytologically in 29 cases. The most frequently diagnosed breeds were Flat-Coated Retrievers (n=16, odds ratio [OR] 62.0), Pembroke Welsh corgis (n=15, OR 9.7) and Bernese Mountain dogs (n=14, OR 45.0). Median survival time for all dogs in this study was 43 days. In the dogs that received no treatment or only symptomatic treatment, the median OS was 12 days (range 2–254 days) compared with that of dogs that received surgical treatment and/or chemotherapy (85 days, range 4–360 days). Univariate analysis identified anemia, thrombocytopenia, hypoalbuminemia, hypoproteinemia and not receiving antitumor treatment (chemotherapy and/or surgery) as factors significantly associated with shorter OS. Multivariate analysis confirmed that platelet counts, localized/disseminated lesional pattern and whether the dog received antitumor treatment were significantly predictive of survival.

Some individuals manifest psychosomatic symptoms after the death of their pets. A survey was conducted at four public and commercial animal cremation service centers in Japan. In each center, a questionnaire was distributed to 100 individuals (400 in total). The questionnaire consisted of the 28-item version of the General Health Questionnaire (GHQ28), the social readjustment rating scale (SRRS) and a series of questions regarding demographic information and the circumstances of their pet’s death. In total, 82 returned questionnaires were available for analysis. GHQ28 proved the existence of neurotic symptoms in 46 responses (56.1%; 95% confidence interval: 44.7–67.0%). Analysis of the responses using the GHQ28 subscales with a Likert scoring system demonstrated more somatic dysfunction in females (GHQ-A: P=0.04). Furthermore, significant correlations were identified among the following factors: owner’s age (GHQ-A: P=−0.60, P=0.01; GHQ-B: P=−0.29, P=0.01; GHQ-C: P=−0.32, P<0.01; GHQ-D: P=−0.42, P<0.01), SRRS score (GHQ-A: P=0.32, P<0.01; GHQ-B: P=0.25, P=0.02; GHQ-D: P=0.30, P=0.01) and animal’s age (GHQ-D: P=−0.26, P=0.02). The death of indoor pets caused deeper depression (GHQ-D: P=0.01) than that of outdoor or visiting pets. The results revealed neurotic symptoms in almost half of the pet owners shortly after their pet’s death.

Soil samples from the ground surface and feces and blood from a mixed-breed male pig were collected on April 10, 2011 at a farm within 20 km of the Fukushima Daiichi nuclear power plant. The radioactivity of each sample was measured using a Ge semiconductor detector. Despite the fact that the pig had been fed non-contaminated imported feed, 131I, 134Cs, and 137Cs were detected in the feces, and 134Cs and 137Cs were detected in the blood clots. Because it is considerably difficult to measure radioactive contamination in the edible muscle of living livestock, bioassays are an option for the screening of radioactive contamination in living livestock to ensure food safety.

Classical swine fever (CSF) is a highly contagious systemic hemorrhagic viral disease of pigs. Wild boar plays a crucial role in the epidemiology of CSF. Between 2010 and 2014, samples were collected nationwide from 6,654 wild boars hunted in South Korea. Anti-CSF antibodies were identified in 0.59% (39 of 6,654) of the wild boar samples using a virus neutralization test and were primarily detected in wild boars living close to the demilitarized zone and the area of the Taebaek Mountains surroundings. The CSF virus (subgroup 2.1b) was isolated from two wild boars captured in a nearby border area. The criteria used to define high-risk areas for targeted CSF surveillance in South Korea should be further expanded to include other regions nationwide.

Hypoxic conditions in various cancers are believed to relate with their malignancy, and hypoxia inducible factor-1α (HIF-1α) has been shown to be a major regulator of the response to low oxygen. In this study, we examined HIF-1α expression in canine lymphoma using cell lines and clinical samples and found that these cells expressed HIF-1α. Moreover, the HIF-1α inhibitors, echinomycin, YC-1 and 2-methoxyestradiol, suppressed the proliferation of canine lymphoma cell lines. In a xenograft model using NOD/scid mice, echinomycin treatment resulted in a dose-dependent regression of the tumor. Our results suggest that HIF-1α contributes to the proliferation and/or survival of canine lymphoma cells. Therefore, HIF-1α inhibitors may be potential agents to treat canine lymphoma.

A 7-year-old, miniature dachshund was referred for examination and treatment of persistent anorexia, deep yellow-coloured urine and leucocytosis. The clinical sign of jaundice, results from a serum biochemistry profile and ultrasonographic images suggested a biliary tract obstruction. A cholecystectomy was performed to remove the obstruction. Histopathological assessment of the resected gallbladder and partial common bile duct indicated diffuse large B-cell lymphoma. Twelve days after the initial operation, a second procedure was performed due to bile leakage into the abdominal cavity. Chemotherapy was administered twice after the second operation but discontinued, because the dog showed adverse effects. The dog is still alive 24 months after the surgery. To the authors’ knowledge, this is the first description of canine gallbladder lymphoma.

Foot-and-mouth disease (FMD) occurred recently for the first time in a decade in Japan. The index case was detected on a beef-breeding farm in Miyazaki Prefecture, Southern Japan, on April 20, 2010. After confirmation of this first case, control measures such as stamping out, movement restriction and disinfection were implemented. However, these strategies proved insufficient to prevent the spread of FMD and emergency vaccination was adopted. Up until the last outbreak on July 4, 2010, a total of 292 outbreaks had been confirmed, with about 290,000 animals having been culled. The epidemic occurred in an area with a high density of cattle and pigs, making disease control difficult. Invasion of the disease into a high-density area aided its rapid spread and led to difficulties in locating suitable burial sites. Epidemiological investigations indicated that the disease was introduced into Japan approximately one month before detection. This delay in initial detection is considered to have allowed an increased number of outbreaks in the early stage of the epidemic. Nevertheless, the epidemic was contained within a localized area in Miyazaki Prefecture and was eradicated within three months because of intensive control efforts including emergency vaccination. Although this epidemic devastated the livestock industry in Japan, many lessons can be learnt for the future prevention and control of infectious diseases in animals.
