The prevention and management of brucellosis depend heavily on the cleanliness of the areas around animals and the effective eradication of infection from animal housing. In our investigation, we tested a variety of disinfectants against Brucella melitensis to see how well they worked and whether they would work in various environmental settings. In addition to three different types of nano-disinfectants (Dettol with Silver-NPs, Glutaraldehyde with Silver-NPs, and Calcium oxide-NPs), our study included various conventional forms of disinfectants and antiseptics (Virkon[Formula: see text] S, Cidex, Sodium hypochlorite, Betadine, and Dettol). For estimating the effectiveness of various types of applied disinfectants, reduction rate was employed. The findings indicated that the concentration and length of exposure time of the disinfectants employed, particularly Vircon S, had an impact on their ability to kill bacteria. However, the presence of filthy circumstances and low temperatures considerably reduced the effectiveness of disinfectants, particularly Dettol. On the other hand, nano-disinfectants, particularly glutaraldehyde containing silver nanoparticles, showed better effects than conventional ones. Our research indicated that disinfectants used in everyday life had an impact on Brucella melitensis. However, the presence of filthy environments and low temperatures reduced the bactericidal effectiveness. The impact of nano-disinfectants on Brucella was better.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139207570","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}

To evaluate the reliability of commercial enzyme-linked immunosorbent assay (ELISA) kits, imported commercial test kits (namely, A, B and C) were used to test field samples. The results were further compared with hemagglutination inhibition (HI) test to figure out the consistency. Results showed that the three commercial ELISA kits had only partial consistency with HI results. In fact, testing results of breeders and layers bore resemblance to HI, whereas there were ELISAs negatively detecting results of broilers opposed in HI. The specificities of these ELISA kits were 0.45, 0.86 and 0.77 for kits A, B and C, respectively, and their sensitivities were 0.79, 0.68 and 0.70, respectively. The commercial ELISA kits may not sustainably provide us the whole view of birds infected or vaccinated status. Based on the results of in-house ELISA and western blot, different IBV strains showed different antigen–antibody interaction. Thus, different ELISA coatings with different antigens might result in different antibody titers. Furthermore, according to HI results, 91% (256) and 70% (198) of the 282 tested sera were positive to H120 (as a Massachusetts vaccine) and 3263/04 (as a field strain), respectively. These high positive rates indicate that in spite of popular use of Massachusetts vaccines, the chickens are still commonly infected with field IBVs in Taiwan.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139255490","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}

Rat models are commonly used to explore the complex pathophysiology and potential treatments of these diseases. The models of high intraocular pressure (HIOP)-induced retinal ischemia-reperfusion imply the ischemic outcome weight on the inner retina layers (including the nerve fiber layer, retinal ganglion cell (RGC) layer, inner plexiform layer (IPL), and inner retinal layer (INL)) that eventually progressed to the outer retinal layers. Depending on the duration (cycles) of ischemic treatment, more glaucoma pathological change signs may be exhibited more obviously with time. The model requires a short ischemic treatment and anticipates an adequately long period of disease manifestation. To investigate photoreceptor-led retinal degeneration, rat models for light-induced retinopathy are commonly used and it is predominantly attributed to the photoreceptor cells damage of ONL and OPL loss by high intensity of light exposure. This model unraveled the pathophysiological impairment of phototransduction as well as disease mechanisms involving oxidative stress and inflammatory process of the outer retinal layer. With the knowledge gained from the research using these animal models, better understanding of the disease mechanisms in terms of its pathophysiology and molecular changes can be achieved. Besides, the rat models can serve as the key basis for further investigation into the therapeutic or preventive perspectives of these retinopathies.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139258433","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}

However, choosing a single optimal parameter among different studies is challenging. This study aimed to identify optimal parameters for AAI in small-breed dogs by simultaneously evaluating the flexed and nonflexed lateral radiographs. Moreover, the potential of using serial trichotomization with multiple parameters was investigated. Radiographs of 10 dogs diagnosed with AAI on magnetic resonance imaging (MRI) were compared with 26 control dogs to select parameters with the area under the curve ≥0.9 or ≤0.1. Parameters with outstanding discrimination included cranial border distance and C1–C2 angle on nonflexed radiographs and dens length on ventrodorsal radiographs. Using cutoff values reflecting 100% sensitivity and 100% specificity, the subject was determined into AAI diagnosed, ruled-out or indeterminate. The accuracy rate was 100% for each of the parameters. However, 31–47% of dogs were classified as indeterminate. Serial trichotomization in the order of dens length, cranial border distance, and C1–C2 angle significantly reduced the proportion of dogs in the uncertainty zone while maintaining accuracy. The established method was tested on 19 new subjects. A similar trend of high accuracy (100%) and small uncertainty zone (5%) was observed in the validation cohort. For certain breeds, serial trichotomization with dens length on the ventrodorsal radiograph and cranial border distance and C1–C2 angle on the nonflexed lateral radiograph showed good potential for determining AAI and identifying dogs in which advanced imaging is indicated for diagnosis.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135928658","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}

On the contrary, its attenuated strain through 75 chicken embryo passages did not. The nucleotide sequence differences in S1 genes before and after attenuation were C166A and G280T, resulting in amino acid changes of P56T and A94S. The S1 and S genes of the wild strain were cloned and expressed in a baculovirus (B) expression system. To test the relationship between HA activity and the S sequence changes after attenuation, the two nucleotide residues were mutated. The HA activity of those recombinant baculoviruses (rBs) was tested. The results showed that rB containing S gene from wild strain possesses the HA activity, that containing S gene with C166A mutation shows partial HA but that containing G280T mutation shows no any HA activity.

Recently, intracellular microsporidia were identified as a causative agent of hepatopancreatic microsporidiosis (HPM). To date, HPM has been listed as an emerging threat to shrimp farming industries because of reduced shrimp growth and survival rates which are considered to be a wasting disease. This study investigated the outbreaks of HPM in farmed Penaeus vannamei in Taiwan. Sixty-five shrimp samples were collected from Taiwan. The proportion of HPM-positive cases was 48% (31/65). Additionally, the gross signs in infected shrimp were stunted growth, sloughed hepatopancreas (HP), and lethargy. The smear impression on the HP also revealed the existence of large EHP spores. Nested-PCR findings identified that 9 cases were confirmed to be positive for the EhSWP1 gene in the first step and 22 cases tested positive for the second step. Phylogenetic analysis of EHP from Taiwan showed 100% similarity to EHP from Thailand, India, and the United States. Histopathological analysis of the HP revealed haemocyte infiltration and the presence of EHP spores in the hepatopancreatic tubule epithelial cells. These results demonstrated that EHP is the main cause in shrimp farms in Taiwan.","PeriodicalId":22157,"journal":{"name":"Taiwan Veterinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77813655","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}

The disease can be caused by eating undigested items, e.g. plastic rope or bags. Since the COVID-19 pandemic, it has often become mandatory for people to wear medical masks. People are generally unaware that masks left on the ground pose a risk to goats who may eat them. This case report describes the rumen bloat caused by medical masks in a male goat reared in an elementary school. After physical examination, the goat showed a bloated rumen, anorexia, depression, and weakness. The heart rate was normal, but respiratory patterns were fast and deep. Fewer defecated feces were noted by the owner. Furthermore, the owner’s complaints and ultrasound images revealed that undigested items in the rumen were the cause. After performing a standard rumenotomy, we scooped out four medical masks, one plastic bag, and one high-density nylon rope from the rumen. We believe this was the first report describing the risk of medical masks in goats.
