Microparticle (MP)-associated tissue factor (TF) activity in plasma might play a role in human disseminated intravascular coagulation (DIC). The aim of this study was to compare MP-TF activity between non-DIC and DIC groups. Ten clinically healthy beagles and 26 diseased dogs were enrolled. The proportion of dogs with increased MP-TF activity was significantly higher in the DIC group than the non-DIC group (P=0.014). MP-TF activity in the DIC group was significantly higher than the non-DIC group (P=0.021). MP-TF activity positively correlated with plasma D-dimer concentration (r=0.42, P=0.034). Moreover, MP-TF activity was decreased by the time of recovery in some dogs with DIC. Larger prospective studies are warranted to assess its value as a diagnostic and prognostic biomarker in DIC.

7年間にわたり毎日植物(雑草)を食べては嘔吐することを繰り返していた11歳去勢雄ミニチュアプードル犬が来患した。犬は散歩に行くたびに雑草を食べ、その後嘔吐することを繰り返していた。医学的検査では異常は認められなかった。行動学的検査と稟告を通して、我々はこの犬が植物を摂食する何らかの理由を有していると診断した。我々は犬が餌に欠乏しているものを補充するため、あるいは消化を助けるために植物を摂取していると推測したので、飼い主に現在の餌を与えることを中止し、高繊維食餌を与えるよう指示した。その結果、餌を高繊維食餌に変えて3日後より植物摂食と嘔吐が無くなったことを飼い主から聞いた。餌を高繊維食餌に変えて13ケ月間、犬に臨床検査上問題は無かった。以上のことは、特に繊維欠乏食が犬の植物摂食行動に関係している事を示唆している。

Kestose, a fructooligosaccharide (FOS) with one fructose monomer linked to sucrose, is a key component of the prebiotic activity of FOS. This study aimed to evaluate the prebiotic potential of Kestose in terms of the impact on population change in the intestinal microbiota and fecal short-chain fatty acid (SCFA) concentration in dogs. Kestose 2 g per dog was administered daily with conventional diet to 6 healthy, adult beagle dogs for 8 weeks followed by 4 weeks of follow-up period without Kestose supplementation. Fresh fecal samples were obtained before and every 4 weeks until the end of the follow-up period. Genomic DNA extracted from the fecal samples was subjected to 16S rRNA gene analysis using next generation sequencer and to quantitative polymerase chain reaction (qPCR). Fecal acetate, propionate, butyrate, lactate and ethanol concentrations were measured by high-performance liquid chromatography. 16S rRNA gene analysis and qPCR showed increasing trend of genus Bifidobacterium after Kestose supplementation while genera Bacteroides and Sutterella decreased. Clostridium perfringens decreased below the detection limit within first 4 weeks after starting Kestose supplementation. Fecal butyrate concentration was significantly increased at week 8 and returned to the base level after 4 weeks of the washing period. To the best of our knowledge, this is the first study to reveal effect of Kestose on the populational changes in fecal microbiota and fecal butyrate concentration in dogs.

A 3-year-old male Rottweiler presented with the chief complaint of recurrent vomiting, diarrhea, hypothermia, and lethargy. Hypovolemic shock was noted with abnormal electrolytes (Na/K ratio, 27.9) and anemia (hematocrit, 17.3%). Since the hematocrit was 49.2% four days earlier when the primary veterinarian examined the dog, acute anemia was diagnosed. Melena was observed on the next day. The general condition and hydration improved with treatment, and an adrenocorticotropic hormone stimulation test identified hypoadrenocorticism. However, the hematocrit decreased further to 9%, necessitating blood transfusion. The cause of severe acute anemia was thought to be gastrointestinal hemorrhage. It should be noted that hypoadrenocorticism can lead to potentially fatal anemia with gastrointestinal tract bleeding, and blood transfusion may be required.

In this study, we document a case of phenobarbital-induced anticonvulsant hypersensitivity syndrome (AHS), which has been rarely reported in veterinary medicine. A 2-year-old, 5.4 kg, neutered male Russian Blue cat was diagnosed with idiopathic epilepsy and started on phenobarbital treatment. Eight days after initiation of phenobarbital treatment, the cat showed tachypnea and hyperthermia. CBC and serum biochemistry were unremarkable. However, the patient showed high serum amyloid A (SAA). On abdominal ultrasonography, generalized enlargement of abdominal lymph nodes and splenic multiple hypo-echoic nodules, which were consistent with reactive lymphadenopathy were found. The cat was diagnosed with AHS, and phenobarbital was discontinued. After 10 days of cessation, the patient had normal SAA, and clinical signs were resolved.

Physical disturbances are common in dogs with canine cognitive dysfunction (CCD). However, the relation between these physical disturbances and CCD has not been clarified. The aim of this study was to clarify the physical disturbances in CCD by questionnaire survey. The questionnaire consisted of items of general information, physical disturbances (gait and posture abnormalities, and deteriorating perception) and a CCD assessment scale named the CCD rating scale (CCDR). The survey was conducted toward owners of dogs aged 10 years or older in two ways: A web-based (Web survey) and a paper-based (Paper survey) survey. To determine which physical disturbances were associated with CCD, ordinal logistic regression analyzes were performed. Through the Web survey, 726 valid responses were obtained, and the test results revealed that vision impairment, smell disturbance, tremor, swaying or falling and head ptosis were significantly associated with CCD. These items, except for head ptosis, were also significantly associated with, or tended to be associated with, CCD in 103 valid responses to the Paper survey. The prevalence of CCD was increased in the elderly dog population, especially in dogs aged 16 years or older. In contrast, physical signs gradually increased from 10 years of age. These results suggest that physical disturbances may appear in the early stages of CCD. In conclusion, the present study revealed new clinical signs of CCD linked to physical disturbances and suggested that these signs could be useful for detecting early stage of CCD.

A cat was referred because of diffuse parenchymal lung disease. Close examinations revealed a swollen abdominal lymph node and multiple nodules of the liver. Mycobacterium avium subspecies hominissuis infection was confirmed by culture and single nucleotide polymorphism analysis of samples recovered from the liver and bronchoalveolar lavage. After administration of combination antibiotics for 6 months, culture results were negative. Though atonic seizures were observed during the treatment, it disappeared after isoniazid discontinuation and pyridoxal phosphate administration. On day 771 of illness, no clinical signs, lung diseases, or obvious swelling of lymph nodes was observed. This is the first report to confirm Mycobacterium avium subspecies hominissuis infection in cats through gene analysis and to completely cure it with combination antibiotics.

Liver-type fatty acid–binding protein (L-FABP) is a biomarker for the early detection of renal diseases in humans. It is secreted along with cytotoxic oxidation products from proximal tubular epithelial cells under conditions of ischemia and/or oxidative stress. This study examined urinary L-FABP excretion under renal ischemia in feline acute kidney injury (AKI) model. L-FABP excretion increased immediately after renal ischemia/reperfusion, despite the absence of obvious structural damage to the kidneys, in the two AKI model cats studied. L-FABP was detected in the renal tubular lumen immediately after renal ischemia/reperfusion in the two cats, but not in a sham surgery cat. These results suggested that high L-FABP excretion is a pathophysiological response associated with antioxidant defense in proximal tubules with renal ischemia and/or oxidative stress in a feline model.

Pulmonary mycosis is a fungal disease that commonly affects bottlenose dolphins (Tursiops truncatus) and is generally treated by the oral administration of azoles, such as itraconazole (ITZ) and voriconazole (VRZ). However, antifungal susceptibility testing of clinical isolates has not been well performed as a routine clinical examination in aquaria. In this study, we collected fungal species from the blowholes of 14 bottlenose dolphins, of which 12 were treated with ITZ or VRZ. All dolphins were housed in the Port of Nagoya Public Aquarium. The fungal species Candida albicans, C. tropicalis, C. glabrata, Aspergillus fumigatus, and A. niger were isolated. E-tests were performed to determine the minimum inhibitory concentrations (MICs) of ITZ and VRZ on these isolates. VRZ-resistant C. tropicalis (MIC: >32 μg/ml) and A. niger (MIC: >32 μg/ml) were isolated from three dolphins treated with ITZ or VRZ. Additionally, azole-resistant isolates of C. albicans and C. glabrata were collected from two dolphins that had never received azole therapy. To the best of our knowledge, our study is the first to report the isolation of VRZ-resistant C. albicans, C. tropicalis, and A. niger from the blowholes of bottlenose dolphins. Thus, antifungal susceptibility testing is a crucial strategy for selecting antifungal agents to treat respiratory fungal infections in bottlenose dolphins in aquaria.

It is known that oxidative stress is related to disease in humans and dogs. Many traditional Chinese medicines have been reported to have anti-oxidative effects, but there are no reports that they have anti-oxidative effects in dogs. In this study, we examined the anti-oxidative effects of Juzen-taiho-to, a traditional Chinese medicine, in dogs. Five healthy female beagle dogs (38–41 months of age weighing 8.6–10.7 kg) were orally administered Juzen-taiho-to at 450 mg/kg with food for 28 days. Blood samples were taken from all five dogs on days 0, 7, 14, 21, and 28. Using the blood samples, improvement of the antioxidant level as assessed by the biological antioxidant potential (BAP), reduced oxidative stress level as assessed by derivatives of reactive oxygen metabolites (d-ROMs), and improvement of blood fluidity were examined. Regarding the antioxidant level and blood fluidity, no significant difference was observed, but the oxidative stress level on days 14, 21, and 28 was significantly lower than that on day 0. Thus, Juzen-taiho-to may have anti-oxidative effects in dogs by reducing oxidative stress and be useful for oxidative stress-related diseases in dogs.

Left atrial enlargement (LAE) is a well-known negative prognostic factor in dogs with myxomatous mitral valve disease (MMVD). Left atrial-to-aortic root ratio (LA/Ao) is the most commonly used method to evaluate left atrial (LA) size in dogs, while the left atrial anteroposterior diameter (LAD) has been proposed as an additional measurement of LA size in different species. The aim of this study was to establish a normal reference range of LAD normalized to body weight (LADn) in dogs using allometric scales, and to evaluate the agreement between LADn and LA/Ao in the detection of LAE in dogs with MMVD. This was a retrospective, multicenter, observational study. We included 330 healthy dogs, 30 dogs with MMVD in ACVIM stage B1, 30 dogs in ACVIM stage B2, and 30 dogs in ACVIM stage C. The reference range for the LAD, depending on body weight, was between 16.91 mm and 49.68 mm. The reference range for the LADn in healthy dogs was between 10.49 and 15.72. LADn was significantly greater in dogs with MMVD compared to healthy dogs, and a significant difference in LADn was noted between different ACVIM stages (P<0.001). The most accurate cut-off value of LADn to differentiate between dogs in groups B2 and C was 20.3 (sensitivity, 83.3%; specificity, 83.3%). There was a misclassification rate of 37% between LADn and LA/Ao in the detection of LAE in group B1. This study provides a normal reference range for LAD in dogs, which can be used as an additional tool to assess LAE in dogs with MMVD.

The accuracy of urine analyzers used for dogs and cats has remained uncertain. This study examines the agreement between results of urine analysis obtained using two devices marketed for animals and for humans and the results of quantitative biochemical analysis. The degrees of concordance for bilirubin and ketones in the same category were ∼80%, but for pH these were only ~60% in dogs and cats. Degrees of concordance for protein and the UP/C ratio clearly differed between the devices for animals and humans. We found that values for bilirubin and ketones obtained using urine analyzers may be reliable, but pH is unlikely to be accurate enough to be clinically useful for dogs and cats.

In healthy dogs, amino acid infusion significantly attenuates the decrease in body temperature during anesthesia by facilitating insulin secretion, suggesting that such an increase in insulin secretion is related to increased heat production. In dogs, selective cyclooxygenase-2 (COX-2) inhibitors, which are used for pain relief in veterinary medicine, possess anti-pyretic action. And, in mice and humans, selective COX-2 inhibitors increase insulin secretion and sensitivity. Therefore, treatment with COX-2 inhibitors may negate or accelerate the attenuating effect on decreased body temperature during anesthesia by amino acid infusion. In the present study, influences on insulin secretion and body temperature by treatment with meloxicam or robenacoxib at therapeutic dose were evaluated in healthy dogs. Treatment with meloxicam or robenacoxib did not affect insulin secretion in the unanesthetized and anesthetized dogs, and did not affect body temperature and heart rate under the anesthetized condition with amino acid infusion. In conclusion, COX-2 inhibitors at therapeutic doses did not affect body temperature during anesthesia in dogs administered amino acids.

Phenobarbital (PB) decreases the cyclosporine (CsA) blood level in humans. However, the interaction of PB with CsA has not been reported in cats. This study investigated the effects of multiple doses of PB on the pharmacokinetics of CsA in three healthy cats. The treatments included oral CsA 5 mg/kg alone and oral CsA 5 mg/kg plus PB 5 mg/kg for 4 weeks. Co-administration of PB with CsA resulted in significant decreases in the oral bioavailability of CsA though both the first pass and elimination phases. These preliminary results suggest that oral administration of multiple doses of PB increases the required CsA dosage in CsA-based immunosuppressive therapy in cats.

古典型豚コレラが発生した3つの生産一貫経営農場において, 全ての病豚を淘汰し集中的なワクチンプログラムを導入した. 雌雄豚は6ヵ月おきに, 子豚は6と8週齢時にワクチンを接種し, 感染の度合を臨床所見及び血清学的検査によりモニターした. 血清学的検査の結果は臨床所見と一致しており, 汚染農場では高力価の抗体を保有する豚や抗体陽性の豚が多くみられたが, 臨床的に豚コレラがフリーの農場ではワクチン投与による低力価抗体が検出されたのみであった. 今回のワクチネーションでは病状の回復が観察されたが, いずれの農場においても豚コレラを制圧することはできなかった. 全ての農場で, 飼育最終段階でも少数の豚が感染していた. これらの豚は6, 8週齢時のワクチンに十分反応していなかったようであり, ワクチンプログラムに検討の余地がある. また, 感染農場の雌豚では高力価の抗体が検出された. この事はこれらの豚から産まれた子豚では受身免疫の期間がより長くなり, それに伴いワクチン接種の最適時が遅くなることを示している. 豚コレラを制圧するためには, 8週齢時以降のワクチネーションも含めたより集中的なワクチンプログラムの導入の必要性が示唆された.

The paracrine function of mesenchymal stem cells (MSCs) during transplantation has been recently studied due to its poor differentiation ratio. Dimethyloxalylglycine (DMOG) has been used to promote angiogenesis in experimental animal models, however, comparable approaches for canine MSCs are not sufficient. In the present study, we assessed whether DMOG improves angiogenesis in canine adipose tissue-derived mesenchymal stem cells (cAT-MSCs). cAT-MSCs were treated with DMOG and their effect on angiogenesis was investigated by cell proliferation assay, western blotting, and tube formation assay. Dimethyloxalylglycine preconditioning enhanced the expression of vascular endothelial growth factor (VEGF) among pro-angiogenic factors in cAT-MSCs via hypoxia-inducible factor-1α stabilization. Dimethyloxalylglycine primed-cAT-MSC-conditioned media increased angiogenesis in human umbilical vein endothelial cells. These results suggest that DMOG conditioning of cAT-MSCs augmented the secretion of VEGF, which acted as a prominent pro-angiogenic factor during angiogenesis. DMOG-primed cAT-MSCs may have the potential to induce beneficial effects in ischemic diseases in clinical trials.

In human medicine, computed tomography (CT) is the gold standard for visceral fat measurement. Research shows that the visceral fat area (VFA) of the umbilical slice is significantly correlated with the visceral fat volume (VFV). In veterinary medicine, however, few studies have evaluated visceral fat using CT. This study aimed to evaluate the visceral fat in dogs using CT images, and determine if the slice significantly correlated with VFV to simplify visceral fat measurements. This retrospective study includes data on 90 dogs that underwent whole-body CT scans for diagnostic purposes. VFV was calculated as the product of VFA and thickness in each CT slice; the correlation between VFV and VFA was analyzed at the level of each lumbar vertebra. Visceral fat percentage (VF%) was calculated as the ratio of the product of VFV and fat density to the body weight. Visceral fat area percentage (VFA%) was calculated as the ratio of VFA to the body area, and its correlation with the VF% and the body condition score (BCS) was analyzed. VFA was highly correlated with VFV at the level of each lumbar vertebra, with the highest correlation (r=0.964) at the L3 level. VFA% was significantly correlated with VF% (r=0.930) and weakly correlated with BCS (r=0.523). This study demonstrates that it is sufficient to use only the L3 slice for visceral fat evaluation and that the evaluation can be based on VFA% of the L3 level.

Surveillance of Echinococcus multilocularis in 98 pet dogs kept in a rural area of Hokkaido, Japan, from March 2018 to March 2019 suggested infection in seven dogs (7.1%) by E. multilocularis-specific copro-DNA examination, and one of them excreted E. multilocularis eggs that were identified by sequence analyses. Among the infected dogs, three were not allowed to run free when outdoors. Based on detection of E. multilocularis eggs in fox feces collected from roadsides in the same area, dogs kept in rural areas may have a high probability of becoming infected after preying on infected voles along such roadsides, even in domesticated settings. Therefore, examination along with periodic deworming administration is considered necessary to prevent transmission from dogs to owners.
