So far, there are only two relevant published reports focused solely on Escherichia coli and Salmonella in Taiwan. This paper describes the emergence of colistin-resistant Klebsiella pneumoniae and Enterobacter cloacae clinical isolates harboring mcr-1 on chromosomes in Taiwan. All four mcr-1-positive isolates were from 63 Klebsiella spp., and the isolated Enterobacter spp. were from diseased dogs and cats at Veterinary Teaching Hospital, National Chiayi University. These four isolates were resistant to colistin, amoxicillin, doxycycline and oxytetracycline, and all mcr-1 genes were located on the chromosome, without any flanking ISApl1 or other insertion sequences. The findings suggest that, in addition to food animals and humans, companion animals can serve as reservoirs of mcr-1, adding another layer of complexity to the rapidly evolving epidemiology of plasmid-mediated colistin resistance in the community. Hence we consider it essential to continue to survey resistance to colistin in these bacteria. Continuous microbiological and molecular surveillance is necessary to assist in early detection and minimize the dissemination of mcr-1.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74925623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies showed that BTV in ruminants in Taiwan was often subclinical infection. The aim of this study was to determine the current status (years 2016–2017) of BTV infection in ruminants in Taiwan, to compare it to the results of a large-scale study conducted in the year 2003, and to investigate whether new viral strains exist. Competitive ELISA tests of serum samples for anti-BTV-VP7 group-specific antibody revealed seropositive rates of 26.7% in cattle by head, similar to 32.7% in the year 2003, suggestive of a BTV-vector-host (cattle) dynamic balance. In goats, the seropositive rate was 18.6%, slightly increased from 8.2% in the year 2003, suggestive of a slow but active infection taking place. This notion was supported by the detection of VP1 gene nucleic acid from whole blood in six out of 29 seropositive goats by reverse transcription–polymerase chain reaction. However, no new virus strain was isolated from embryonating chicken embryos (ECEs) inoculation. Alignment of VP7 amino acid sequences revealed that Taiwan and Japan isolates possessed three specific amino acids on sites No. 82 (arginine), No. 328 (aspartate), and No. 336 (glutamine), which are different from many countries. In a three-dimensional model, these amino acids were located closely on the middle lateral surface of VP7 trimers. Since VP7 is a major outer protein engaged in entry into insect cells and a strong T cell response inducer, these differences likely indicate the result of positive selection of local vectors and hosts in Taiwan.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79968987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cats that underwent surgical treatment, median OST was longer in cats that underwent surgery with adjuvant chemotherapy (540 days) than cats that underwent surgery without chemotherapy (398 days). In addition, cats with FMCs in early stage (I or II) had longer OST than cats in advanced stages. Further, through multivariate analyses, the histological grade was found to be significantly associated with a survival of two years. Cats with FMCs at high grade were most likely to have a mean or median OST of less than one year.

The immune system comprises innate and adaptive immunity. Innate immunity relies on pattern recognition receptors to sense particular molecules present in pathogens, i.e. pathogen-associated molecular patterns (PAMPs), or danger signals in the environment, i.e. danger-associated molecular patterns (DAMPs). Cytoplasmic retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) and nucleotide-binding oligomerization domain-like receptors (NLRs) are the sensors recognizing cytoplasmic PAMP and/or DAMP. Among common avian species, chickens do not have RIG-I whereas ducks and finches do. Therefore, the other RLR member, melanoma differentiation-associated gene 5 (MDA5), is believed to play an important role to recognize intracellular pathogens in chickens. Chicken MDA5 has been identified and its function determined. Chicken MDA5 maintains the same domain architecture compared with MDA5 analogs in other animal species. The expression of chicken MDA5 was upregulated when a synthetic double-stranded RNA (dsRNA), polyriboinosinic:polyribocytidylic acids (poly(I:C)), was transfected into chicken cells, whereas that did not change when cells were incubated with poly(I:C). The enhanced expression of chicken MDA5 in chicken cells upregulated the expression of chicken interferon-[Formula: see text] (IFN-[Formula: see text]). The infection of dsRNA infectious bursal disease virus (IBDV) in non-immune cells triggered the activation of chicken MDA5 signaling pathway, leading to the production of IFN-[Formula: see text] and subsequent response of IFN-stimulated genes. Furthermore, in immune cells like macrophages, chicken MDA5 participated in sensing the infection of IBDV by activating downstream antiviral genes and molecules and modulating adaptive immunity.On the contrary, one of cytoplasmic NLR member, NLR family pyrin domain containing 3 (NLRP3), was cloned and functionally characterized in chicken cells. Chicken NLRP3 conserved the same domain architecture compared with NLRP3 analogs in other animal species. Chicken NLRP3 was highly expressed in kidney, bursa of Fabricius and spleen. The production of mature chicken interleukin 1 [Formula: see text] (IL-1[Formula: see text] in chicken macrophages was stimulated by lipopolysaccharide (LPS) treatment followed by short ATP exposure.In summary, chicken MDA5 was a cytoplasmic dsRNA sensor that mediated the production of type I IFN upon ligand engagement, whereas NLRP3 sensed danger signals, such as ATP, in the cytoplasm and cleaved pro-IL-1[Formula: see text] to produce mature IL-1[Formula: see text]. Chicken MDA5 was not only involved in the activation of innate immune responses in non-immune and immune cells, but it also participated in modulating adaptive immunity in immune cells. Chicken NLRP3 participated in the production of mature chicken IL-1[Formula: see text] upon ligand engagement.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90270851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have described how follicular size is associated with the reproductive stages of yellow-margined box turtles (YMBTs), but our understanding of follicular morphology remains limited. This study describes the different ultrasonographic appearances of preovulatory follicles of these turtles in Taiwan. Randomly selected 28 adult captive female turtles were examined under ultrasonography, weekly from November 2012 to November 2013. The females were divided into ovulatory and non-ovulatory groups with equal number coincidentally based on the whole-year ovulation records. The ovulatory group had significantly larger follicles than the non-ovulatory group (average size of largest follicle, [Formula: see text][Formula: see text]mm versus [Formula: see text][Formula: see text]mm; [Formula: see text]). Across both groups, preovulatory follicles exhibited five different morphologies: previtellogenic, homogeneous, heterogeneous, atretic, and multilayered. The multilayered follicles were only observed in the ovulatory group during the late preovulatory (February) and early ovulatory periods (March), resulting in a significant correlation with ovulatory stage ([Formula: see text]). During the preovulatory period (from December to February), homogeneous follicles were the predominant follicles in both groups. During the ovulation period, heterogeneous follicles were the main follicles, but only in the ovulatory group. Finally, atretic follicles were predominant in the non-ovulatory group during the early latent period (August). This study provides detailed ultrasonographic data clarifying the correlation between turtle follicular morphology and reproductive cycle. A better understanding of how such morphology is associated with reproductive stages should improve breeding programs in zoos and thus facilitate conservation efforts.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85300400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cytology-based screening methods, such as fine needle aspiration (FNA) or immunocytochemistry (ICC), for canine lymphomas lack sensitivity. Despite an improvement in the detection of canine lymphomas by the DNA methylation analysis of lymph scrapings, only few methylation markers have been described. Even though technique like Digital Restriction Enzyme Analysis of Methylation (DREAM) can analyze the methylation profile of canine lymphoma cell line CLBL-1 at very low experimental cost without specific antibodies, the sensitivity and accuracy remain low in comparison to MethylCap-seq. In this study, a methylated DNA fragment of CLBL-1 was successfully captured by a specific protein for MethylCap-seq, and the methylation map of CLBL-1 was reconstructed by high throughput sequencing. For the first time, the genomic methylation region of canine CLBL-1 was analyzed. Using CLBL-1, we aimed to identify novel methylated markers for monitoring canine lymphomas. With the aid of methylation maps, several researchers have attempted to explore the relationship between DNA methylation and specific cancers.
