Inês Tenreiro Tavares, Ramón R Barreno, José P Sales-Luís, Carlo G Vaudano
An elective laparoscopic ovariectomy on a healthy dog revealed a cystic structure in the left ovary. The surgical procedure was successful. Histopathological examination showed the presence of a teratoma adjacent to the ovary. To the best of the authors' knowledge, this is the first reported case of an ovarian teratoma removed by laparoscopic ovariectomy in a dog using a multiport laparoscopic ovariectomy technique.

Porcine parvovirus 7 (PPV7) was first detected in Korean pig farms in 2017. The detection rate of PPV7 DNA was 24.0% (30/125) in aborted pig fetuses and 74.9% (262/350) in finishing pigs, suggesting that PPV7 is circulated in Korean domestic pig farms. Phylogenetic analysis based on VP amino acid sequences demonstrated that the nine Korean strains (PPV-KA1-3 and PPV-KF1-6) were closely related to that of previously reported US and Chinese PPV7 strains. In addition, the Korean strains have genetic diversity with insertion or deletion mutations...

Several studies have reported the effect of absorption of procyanidins and their contribution to small intestine. However, the differences of dietary interventions of procyanidins compared with antibiotic feeding in pigs are rare reported. After 16S rRNA gene Illumina MiSeq sequencing, we found that procyanidin administration for 2 months (procyanidin 1 group) or continuously antibiotics feeding for 1 month and then procyanidin for 1 month (procyanidin 2 group) could increase the number of OTUs, Chao 1 and ACE index compared with antibiotic administration for 2 months (antibiotic group)...

Bacterial biofilms have been demonstrated to be closely related to clinical infections and mainly contribute to drug resistance. Berberine, which is the main component of Coptis chinensis , has been reported to have efficient antibacterial activity. This study aimed to investigate the potential effect of combination of berberine with ciprofloxacin (CIP) to inhibit Salmonella biofilm formation and the effect on the related genes ( rpoE , luxS , ompR ) expressions. The fractional inhibitory concentration index of the combination of berberine with CIP is 0...

Foot-and-mouth disease (FMD) is a highly contagious viral vesicular disease of cloven hoofed animals caused by the foot-and-mouth disease virus (FMDV), which is one of the highly variable RNA viruses. In many countries, vaccines are used for the prevention of FMD. However, because there is no protection against FMD immediately after vaccination, research and development on antiviral agents is being conducted to induce protection until immunological competence is produced. Until now, no cases of the use of an instantly effective antiviral agent in the field for treatment or prevention have been reported...

Dapsone, an antibiotic, has been used to cure leprosy. Although it was reported that dapsone has anti-inflammatory activity in hosts. However, the anti-inflammatory mechanism of dapsone has not been elucidated enough. The present study investigated the anti-inflammatory effects of dapsone on bone marrow cells (BMs), especially upon the exposure of lipopolysaccharide (LPS). We treated BMs with LPS and dapsone. The treated cells were used for cellular activity assay, flow cytometry analysis, the cytokine production, and reactive oxygen species assay...

Goose hemorrhagic polyomavirus (GHPV) is not a naturally occurring infection in geese in China; however, this infection has been identified in Pekin ducks, a domestic duck species. Herein, we investigated the prevalence of GHPV in five domestic duck species (Liancheng white ducks, Putian black ducks, Shan Sheldrake, Shaoxing duck, and Jinyun Sheldrake) in China. We found that the Jinyun Sheldrake duck species could be infected by GHPV with no clinical signs, while no infection was identified in the other four duck species...

The freemartinism syndrome affects almost all female calves born co-twin to males, whereas little is known about sheep females. Within this context, a total of 1,185 ewe-lambs from the Ripollesa sheep breed where genotyped for the oY1 polymorphism (non-autosomal region of the Y chromosome). Neither ewe-lambs from single birth (856) nor ewe-lambs from all-female multiple births (170) revealed as freemartin, whereas five out of 159 ewe lambs from multiple births with male co-twins were freemartin (3.15%±1.38%); all those freemartin ewes were confirmed by physical examination of external genitalia...

Ovaries of 21 bitches presented with gynecopathies were surgically removed and histologically examined. Standard histological as well as immunohistochemical classification of 193 cystic structures resulted in the classification of 72 cysts of subsurface epithelial structures (SES), 61 follicular cysts (FC), 38 cystic rete ovarii (CRO), 13 lutein cysts (LC), and another 9 non-classifiable cysts (NCC). In addition to the histological classification, results were interpreted in the context of the medical history, clinical examination outcome and macroscopic findings during ovariohysterectomy...

The purpose of this study was to evaluate the clinical and imaging characteristics of splenic tumors and to establish guidelines for the pre-surgical assessment of splenic tumors. Fifty seven dogs that received total splenectomy for the treatment of splenic tumors were evaluated by medical records, hematologic results, diagnostic imaging results and histopathologic results. The maximum lesion size from ultrasonography was significantly different between malignant and benign tumors ( p = 0.002). There was a correlation between margination and type of splenic tumors ( p = 0...

Novel H5N6 highly pathogenic avian influenza viruses (HPAIVs) were isolated from duck farms and migratory bird habitats in South Korea in November-December 2017. Genetic analysis demonstrated that at least two genotypes of H5N6 were generated through reassortment between clade 2.3.4.4 H5N8 HPAIVs and Eurasian low pathogenic avian influenza virus in migratory birds in late 2017, suggesting frequent reassortment of clade 2.3.4.4 H5 HPAIVs, and highlighting the need for systematic surveillance in Eurasian breeding grounds...

The bursa of Fabricius (BF) is the central humoral immune organ unique to birds. The bursal peptide BPs (BP-I, BP-II, BP-III, BP-IV) were isolated and identified from BF. In this study, the immunoadjuvant activities of BP-(I-IV) were examined in mice immunized with H9N2 avian influenza virus (AIV) vaccines. The results suggested that BP-I effectively enhanced cell-mediated immune responses, increased the secretion of Th1 (gamma interferon [IFN-γ]) and Th2 (IL-4)-type cytokines, and induced a better cytotoxic T-lymphocyte (CTL) response to the H9N2 virus...

Auditory tube diverticula, also known as guttural pouches, are naturally occurring dilations of the auditory tube in horses that communicate with the nasopharynx through a small ostium. Infection and select other conditions can result in inflammation and narrowing of the nasopharyngeal ostium, which prevents drainage of fluid or egress of air and can lead to persistent infection or guttural pouch tympany. Auditory tube diverticulotomy allows continuous egress from the auditory tube diverticula and is a feature of disease treatment in horses, in which medical treatment alone is not successful...

Influenza virus infection is a zoonosis that has great socioeconomic impact worldwide. Influenza infection induces respiratory symptoms, while influenza virus can infect brain and leave CNS sequelae. As children are more vulnerable to infection, they are at risk of long-term neurological effects once their brains are infected. We previously demonstrated that functional changes in hippocampal neurons were observed in mice recovered from neonatal influenza infection. In this study, we investigated the changes in myelination properties that could affect neural dysfunction...

Staphylococcus aureus is one of the major pathogens causing bovine mastitis and foodborne disease associated with dairy products. To determine the genetic relationships between human and bovine or bovine isolates of S. aureus , various molecular methods have been used. Previously we developed an rpoB sequence typing (RSTing) method for molecular differentiation of S. aureus isolates and identification of RpoB -related antibiotic resistance. In this study, we performed spa typing and RSTing with 84 isolates from mastitic cows (22 farms, 72 cows, and 84 udders) and developed a molecular prophage typing (mPPTing) method for molecular epidemiological analysis of bovine mastitis...

A group of benign Theileria species, which is often referred to as Theileria orientalis/sergenti/buffeli , shows low pathogenicity in cattle. Here, we report the species of Theileria in cattle on a farm from China. We detected 6 genotypes that were categorized as types 1, 2, 3, 4, and 5 as well as an additional type 9 from the phylogenetic analysis of MPSP gene sequences. The new epidemiological features of the T . orientalis/sergenti/buffeli parasites in China reveal a greater diversity in the genetics of these species than had been previously thought...

Fowl adenovirus (FAdV) is distributed worldwide and caused economic losses in poultry industry. The objectives of this study were to determine the hexon and fiber gene changes in an attenuated FAdV isolate of Malaysia in specific pathogen free (SPF) chicken embryonated eggs (CEE) and its infectivity in commercial broiler chickens. SPF CEE was inoculated with 0.1mL FAdV inoculum via chorioallantoic membrane (CAM) for 20 consecutive passages. The isolate at passage 20 (E20) with virus titer of 108.7 TCID50 /mL was inoculated (0...

Arthroscopy has become an attractive modality in the diagnosis and treatment of joint diseases in toy breed dogs. However, the application of arthroscopy is limited by small joint space. Our objective was to evaluate the efficacy of a stifle lever for joint distraction during stifle arthroscopy in toy breed dogs. Paired stifles (n = 32 each) collected from 16 cadavers of toy breed dogs were randomly assigned to one of two groups: the stifle lever group or the external manipulation group. All stifles underwent arthroscopic cranial cruciate ligament transection, and the visualization of the medial meniscus was evaluated...
