Streptococcus parasuis has recently been removed taxonomically from Streptococcus suis, a zoonotic pathogen. S. parasuis has been detected in healthy pigs and in diseased pigs, which suggests that S. parasuis is involved in the normal microbiota of pigs and has potential pathogenicity. However, the pathogenicity of S. parasuis in pigs is unclear because of the lack of appropriate detection methods that discriminate S. parasuis from S. suis. In this study, we developed a PCR method that is specific for S. parasuis. The detection limit of the PCR was 350 CFU per reaction. Bacteria isolated from the saliva of eight pigs were collected and examined by PCR. Sixty-four isolates positive for PCR were obtained from the samples of all pigs. Thirteen of the 64 isolates were genetically confirmed as S. parasuis, and biologically and biochemically had nearly the same features of known S. parasuis strains, which suggested that strains positive for PCR were S. parasuis. Among the 64 isolates, 28 isolates were serotypes 20, 22, or 26 in the S. suis serotyping scheme. The remaining 36 isolates were untypeable, which suggested the presence of novel serotypes or a capsule-negative form. Therefore, the PCR method described in this study is a useful tool for identifying S. parasuis, and can be used in etiological studies on this bacterium.

A 4-year-old, 5.9-kg female Japanese Spitz presented with syncope and exercise intolerance. Echocardiography revealed an ostium primum atrial septal defect (ASD), a cleft mitral valve, mitral valve regurgitation (MR), and tricuspid regurgitation (TR) (velocity: 3.6 m/sec, pressure gradient: 52 mmHg), leading to a diagnosis of partial atrioventricular septal defect (AVSD) with moderate pulmonary hypertension (PH). Open-heart surgery using cardiopulmonary bypass was performed through right atriotomy. The cleft of the mitral valve was sutured with polypropylene and the AVSD was closed using an autologous pericardial patch fixed with glutaraldehyde. No postoperative pulmonary hypertensive crisis occurred. Shunting flow through the ASD, TR, and PH had completely disappeared 2 months postoperatively; however, moderate MR persisted. The dog is still alive 5 years postoperatively without clinical signs.

Localized scleroderma (LS) is a sclerotic skin disorder rarely reported in the veterinary literature. We herein report the first case of a linear LS-like skin lesion in a cat. A 1-year-old castrated male Himalayan cat was presented with a 1-month history of an alopecic, indurated, serpiginous, branched skin lesion on the dorsal cervical to scapular area. The cat had no history of trauma, although a topical spot-on endectocide had been applied near the lesion. Histopathological examination revealed a focal area of hyperplastic dermal collagen with the absence of pilosebaceous units. The cutaneous lesion remained unchanged during a 2-year follow-up period. Clinical and histopathological similarities of this skin lesion with those of the linear form of LS in humans were considered.

A 12-year-old intact male Welsh Corgi was presented with enlargement of the right scrotum. Both testicles were surgically removed and histopathologically examined. On gross examination, white nodules were found in the epididymis and ductus deferens. Histopathologically, the nodules developed continuously from the tunica vaginalis testis of the right scrotum and consisted of spindle-shaped neoplastic cells that invaded the surrounding tissue. Immunohistochemically, the neoplastic cells were diffusely positive for vimentin, cytokeratin and Wilms tumor-1 (WT-1). Based on these findings, the tumor was diagnosed as sarcomatoid mesothelioma. The dog presented with respiratory distress 122 days after surgery and clinical examination found multiple metastatic lesions in the lung, abdominal lymph nodes and peritoneum. The dog died 144 days after surgery due to disease progression.

Remifentanil is an ultra-short-acting μ-opioid receptor agonist. The purpose of this study was to determine the relationship of the minimum alveolar concentration (MAC) of sevoflurane and other MAC derivatives, including the MAC for blocking adrenergic responses (MAC-BAR) and the MAC at which tracheal extubation is occurred (MAC-extubation), with or without remifentanil infusion. Six healthy adult beagle dogs were randomly anesthetized three times for determining the MAC-BAR (SEVMAC-BAR), MAC (SEVMAC), and MAC- extubation (SEVMAC-extubation) of sevoflurane under infusion of saline and remifentanil at rates of 0.15, 0.30, 0.60, 1.20 and 2.40 μg/kg/min. The ratio of the SEVMAC-BAR and SEVMAC and that of the SEVMAC-extubation and SEVMAC were not significantly different at baseline and during treatment. The MAC-BAR95 and MAC95 decreased in a dose-dependent manner until reaching 1.20 μg/kg/min, and the MAC-extubation5 decreased in a dose-dependent manner until reaching 0.60 μg/kg/min. The percentage reduction of SEVMAC-BAR, SEVMAC, and SEVMAC-extubation increased in a dose-dependent manner during remifentanil infusion. The heart rate significantly decreased in the MAC-BAR and MAC groups, and the systolic and mean arterial pressures increased after remifentanil infusion compared with the baseline values. Remifentanil infusion caused reduction of the SEVMAC-BAR, SEVMAC and SEVMAC-extubation in a dose-dependent manner, and ceiling effects were observed in the dogs. Higher doses of remifentanil and sevoflurane were necessary for blocking the sympathetic response to the supramaximal stimulus to prevent movement and extubation in dogs.

Sirtuin-1 (SIRT1) is a nicotinamide adenine dinucleotide (NAD+)-dependent histone deacetylase with a large number of protein substrates. It has attracted a lot of attention in association with extending lifespan. The objective of this study was to enable the evaluation of SIRT1 expression in peripheral blood mononuclear cells (PBMCs) from dogs by flow cytometry. Three transcript variants were amplified from PBMCs by reverse transcription PCR and the nucleotide sequences were analyzed. On the basis deduced amino acid sequence, a monoclonal antibody against human SIRT1, 1F3, was selected to detect canine SIRT1. Canine SIRT1 in peripheral blood mononuclear cells was successfully detected by western blotting using this antibody. Intracellular canine SIRT1 was also detected in permeabilized 293T cells transfected with a canine SIRT1 expression plasmid by flow cytometry using this antibody. SIRT1 was detected in all leukocyte subsets including lymphocytes, granulocytes and monocytes. The expression level was markedly different among individual dogs. These results indicated that the method applied in this study is useful for evaluating canine SIRT1 levels in PBMCs from dogs.

A 5-year-old castrated male poodle presented with blindness. Ophthalmic examinations including slit-lamp biomicroscopy, tonometry, ultrasonography, and electroretinography, were performed. The anterior lens capsule of the right eye (OD) was totally pigmented, with persistent pupillary membranes (PPMs). Ultrasonography of the same eye showed severe lens atrophy and retinal detachment. Electroretinography revealed flat a- and b-waves in OD, but normal amplitudes in the left eye (OS). No ocular defects were detected in OS except mature cataract. In this case, it was determined that hypermature cataract with PPMs, caused both lens-induced-uveitis and total anterior lens capsule pigmentation. This condition needs to be differentiated from absent pupil. Notably, PPMs with total anterior lens capsular pigmentation are extremely rare in dogs.

The present study investigated the prevalence of Toxoplasma gondii and other intestinal parasites in cats in the Tokachi subprefecture in Japan. A total of 365 household cats were included in the study, and 353 serum and 351 fecal samples were collected and analyzed. T. gondii IgG antibodies were detected in the sera of 16.14% of cats based on Latex agglutination test and ELISA. For ELISA, T. gondii RH strain tachyzoites lysate and T. gondii SAG2 recombinant protein were used as antigens. Low seropositivity was detected in cats younger than one year and older than 11 years; outdoor and hunter cats showed significantly high seropositivities. Neutering either in male or female cats, but not gender, had a considerable effect on seroprevalence. Toxoplasma gondii oocysts were detected in one fecal sample. The overall parasitic infestation in cats was 12.5%. Other detected parasites included Toxocara species, which showed the highest prevalence of 7.7%, followed by Isospora spp. (2%), Taenia spp. (1.7%), and Ancylostoma spp. (0.9%). Spirometra spp. was detected in only one sample. Outdoor cats comprised 50% of all 44 parasite-infested cats. Although T. gondii oocysts were detected in only one sample, the relatively high seroprevalence of T. gondii indicated that it can pose significant risks to the environment. Our findings highlighted the potential of outdoor cats as a source of T. gondii and other parasites.

The objective of this study was to evaluate the efficacy of a non-selective COX inhibitor (tolfenamic acid) and a selective COX-2 inhibitor (robenacoxib) for post-operative pain control in cats. Thirty cats undergoing ovariohysterectomy were randomly divided into three groups: the control (placebo) group, the tolfenamic acid (4 mg/kg/day) group, and the robenacoxib (1 mg/kg/day) group. Non-steroidal anti-inflammatory drugs (NSAIDs) were administered orally 2 hr before anesthesia induction and 24 and 48 hr post-operation. Buccal mucosal bleeding times (BMBTs) were assessed prior to anesthesia induction. Colorado pain scores and composite pain scores were evaluated in a blinded fashion before induction and 2, 8, 24, 30 and 48 hr post-operation. The Colorado pain scores of cats receiving robenacoxib were significantly lower than those of cats in the control group at 30 (P=0.0126) and 48 (P=0.0439) hr post-operation. The composite pain scores of cats from the robenacoxib group were lower than those of cats in the control group at 30 (P=0.0299) and 48 (P=0.01030) hr post-operation. The Colorado pain scores of cats receiving tolfenamic acid were significantly lower than those of cats in the control group at 30 hr (P=0.0186) post-operation. The composite pain scores in cats in the tolfenamic acid group were lower than the scores of cats in the control group at 24 (P=0.0403) and 48 (P=0.0413) hr post-operation. BMBTs remained within normal limits in all groups. Both tolfenamic acid and robenacoxib are useful for post-operative pain control in cats.

To trace the prevalence of canine distemper virus (CDV) in diarrhoetic dogs, a total of 201 stool samples were collected in the Heilongjiang province of northeastern China from May 2014 to April 2015. The 201 fecal samples were subjected to the detection of CDV by using RT-PCR targeting the partial N gene, phylogenetic analysis based on the complete H gene, and co-infection analysis. Results indicated that 24.88% (50/201) of the samples were positive for CDV. The fifty CDV samples exhibited an overall co-infection rate of 94% (47/50) with four enteric viruses (82%, 41/50) and five bacteria (72%, 36/50). The positivity rate of CDV exhibited differences among regions, seasons, ages, and immunization status. Phylogenetic analysis of the complete H genes (n=6) revealed that the CDV strains identified in our study belonged to the Asia-1 group, and showed genetic diversities. These data provide evidence that there are a number of genetically diverse CDV Asia-1 strains circulating in diarrhoetic dogs in northeastern China; the CDV-affected animals exhibit the high co-infection with other enteric viruses and bacteria.

A 12 year-old intact male Pembroke Welsh corgi weighing 10.8 kg was presented for evaluation of a 3-month history of dyspnea, and a 1-week history of exercise intolerance and anorexia. Severe hypoxemia (PaO2 56 mmHg), diffuse lung alveolar infiltration, and severe pulmonary hypertension (tricuspid regurgitation pressure gradient was 81 mmHg) were identified. A tentative diagnosis of severe PH due to lung disease or pulmonary thromboembolism was made and treated intensively. After 5 days of hospitalization, the dog died despite oxygen supplementation and anticoagulant therapy. This dog was diagnosed as unclassified interstitial lung disease based on histopathological findings.

Black soldier fly (Hermetia illucens) larvae (BSFL) are rich in protein and have the potential to be used in animal feed. The aim of the present study was to determine the immunoprophylactic effect of BSFL against Salmonella Gallinarum in broiler chicks as an alternative feed additive. Results showed that BSFL improved body weight gain and increased frequency of CD4+ T lymphocyte, serum lysozyme activity, and spleen lymphocyte proliferation. Moreover, BSFL reinforced bacterial clearance and increased survivability of broiler chicks against S. Gallinarum. These data suggested that BSFL has prophylactic properties with stimulating non-specific immune responses, as well as reduced bacterial burden against S. Gallinarum.

Cytotherapy with mesenchymal stem cells (MSCs) has been studied in many species, and often requires in vitro cell expansion to obtain therapeutic doses of stem cells. Because the characteristics of MSCs, such as self-renewal and multi-lineage differentiation, can be altered by long-term culture, it is important to maintain stemness during cultivation. This study assessed the changes in the characteristics of feline adipose tissue-derived (fAT)-MSCs during in vitro passaging. Stem cells isolated from the adipose tissue of donor cats were cultured for seven sub-passages. Proliferation capacity was analyzed by calculating the cell doubling time and by colorimetric assay. Expression of stem cell-specific markers was evaluated by quantitative reverse transcription (qRT)-PCR and immunophenotyping. Expression of adipogenic and osteogenic differentiation markers was also measured by qRT-PCR. Histochemical staining and measurement of β-galactosidase activity were conducted to detect cellular senescence. The cell proliferation rate decreased significantly at passage 5 (P5). Gene expression levels of pluripotency markers (Sox2, Nanog, and Klf4) and stem cell surface markers (CD9, CD44, CD90, and CD105) decreased during continuous culture; in most assays, statistically significant changes were observed at P5. The ability of cells to undergo adipogenic or osteogenic differentiation was inversely proportional to the number of passages. The proportion of senescent cells increased with the number of passages. These results suggest that repeated passages alter the proliferation and multipotency of fAT-MSCs. In clinical trials, early-passage cells should be used to achieve the maximum therapeutic effect.

A 7-year-old castrated male ferret developed unilateral cervical lymphadenomegaly over a 1-month period. Histological examination revealed proliferation of tumor cells in a diffuse and partially nodular pattern. The tumor cells were predominantly Hodgkin cells and binucleated Reed-Sternberg cells, characterized by abundant, clear, vacuolated cytoplasm, pleomorphic, ovoid nuclei with thick nuclear membranes and distinct nucleoli. Multinucleated cells, resembling lymphocytic and histiocytic (L&H) cells, were also observed. Immunohistochemically, the tumor cells expressed Pax-5, BLA-36 and vimentin. A small population of the tumor cells expressed CD20. This case showed proliferation of Hodgkin/Reed-Sternberg cells in conjunction with L&H cells that were histologically analogous to feline Hodgkin’s-like lymphoma. However, Pax-5 and BLA-36 expression along with rare CD20 expression were consistent with classical Hodgkin’s lymphoma in humans.

The aim of this paper is to report two cases of sternal dislocation (SD) in cats and the long-term outcomes with and without surgery. In a cat with poly-traumatized SD (Case 1), mandibular, radial, and ulnar fractures were corrected first, and the SD was allowed to heal without intervention for 14 months. However, normal healing did not occur and sternal instability remained. Therefore, the SD was corrected surgically, and the cat recovered fully within 4 weeks. In a cat with isolated SD (Case 2), surgery was performed, and normal posture and gait were regained after 5 weeks. Furthermore, in both cases, no postoperative complications were observed during follow-up. Therefore, surgical correction of SD in cats is recommended.

A 2-year-old, exotic shorthair cat presented with baldness and mild scaling on trunk that was confirmed as Microsporum canis (M. canis) infection by the following methods. Wood’s lamp and trichogram were used to demonstrate fungal elements suggestive of dermatophytosis consistent with M. canis. Dermatophyte test medium (DTM) and polymerase chain reaction (PCR) were used for identification. E-test and broth microdilution test were then utilized to estimate antifungal minimal inhibitory concentrations (MICs) towards ITZ and TRF respectively. The strain was isolated from the patient and revealing TRF MIC >32 μg/ml and ITZ MIC 0.023 μg/ml. Patient was cured of dermatophytosis with systemic ITZ.

A 29-year-old stallion presented with bilateral blindness following the chronic purulent nasal drainage. The mass occupied the right caudal nasal cavity and right paranasal sinuses including maxillary, palatine and sphenoidal sinuses, and the right-side turbinal and paranasal septal bones, and cribriform plate of ethmoid bone were destructively replaced by the mass growth. The right optic nerve was invaded and involved by the mass, and the left optic nerve and optic chiasm were compressed by the mass which was extended and invaded the skull base. Histologically, the optic nerves and optic chiasm were degenerated, and the mass was diagnosed as lymphoma which was morphologically and immunohistochemically classified as a diffuse large B-cell lymphoma. Based on these findings, the cause of the blindness in the stallion was concluded to be due to the degeneration of the optic nerves and chiasm associated with lymphoma occurring in the nasal and paranasal cavities. To the best of our knowledge, this is the first report of the equine blindness with optic nerve degeneration accompanied by lymphoma.

A 6-year 5-month-old spayed female Scottish Fold cat presented with a one-month history of gait abnormalities, increased salivation, and decreased activity. A blood test showed hyperammonemia and increased serum bile acids. Imaging tests revealed multiple shunt vessels indicating acquired portosystemic shunt. Histopathologic analysis of liver biopsy showed features consistent with liver hypoperfusion, such as a barely recognizable portal vein, increased numbers of small arterioles, and diffuse vacuolar degeneration of hepatocytes. These findings supported the diagnosis of primary hypoplasia of the portal vein/microvascular dysplasia, (PHPV/MVD). To our knowledge, this is the first case of feline PHPV/MVD that developed multiple acquired portosystemic shunts and presented with hepatic encephalopathy.
