Age and breed are considered the greatest risk factors for disease prevalence mortality in companion dogs. Understanding of diseases, relation to age breed, would support appropriate guidance future health care strategies provide useful information early diagnosis diseases. The purpose this study was investigate major medical causes dogs visiting primary-care veterinary clinics Republic Korea, stratified by breed.A total 15,531 records canine patients were analyzed from 11 who shared data...
Pasteurella multocida is responsible for significant economic losses in pigs worldwide. In clinically diseased pigs, most P. isolates are characterised as subspecies multocida, biovar 2 or 3 and capsular type A D; however, there little information regarding subspecies, biovars, other types of Korea. Here, we provided covering an extended time period with pneumonia Korea using phenotypic genotypic characterisations data associated the minimum inhibitory concentrations. The overall prevalence...
Abstract Background African swine fever (ASF), caused by the ASF virus (ASFV), was first reported in Vietnam 2019 and spread rapidly thereafter. Better insights into ASFV characteristics early detection surveillance could help control its spread. However, pathogenicity methods for of isolates from have not been established. Therefore, we investigated explored alternative sampling detection. Results Ten pigs were intramuscularly inoculated with an strain (titer, 10 3.5 HAD 50 /mL), their...
Abstract Ketosis often occurs during the postpartum transition period in dairy cows, leading to economic and welfare problems. Previously, ketosis was reported be associated with hematological serum biochemical parameters. However, association between parameters on calving date remains unclear. This study aimed investigate this association. Blood samples were collected from jugular vein of Holstein cows β-hydroxybutyrate tested once every 3 days (8 times 21 days). The divided into three...
This study aimed to evaluate the efficacy of Lactiplantibacillus argentoratensis AGMB00912 (LA) in reducing Salmonella Typhimurium infection weaned piglets. The investigation focused on influence LA gut microbiota composition, growth performance, and fecal shedding. results indicated that supplementation significantly improved average daily gain reduced prevalence severity diarrhea. Fecal analysis revealed shedding LA-supplemented group. Furthermore, notably altered composition microbiota,...
Activated keratinocytes play a crucial role in skin inflammation through the production of multiple inflammatory mediators; however, little is known about cytokine secretion by activated dogs. This study aimed to investigate effects Th1 and Th2 types cytokines on keratinocyte-derived mediators. Canine progenitor epidermal (CPEKs) were incubated with canine recombinant IL-4, IL-13, an IL4/IL13 mixture, IFN-γ, TNF-α, or IFN-γ/TNF-α mixture for 24 h following 100% confluency. Culture...
ABSTRACT An 11‐year‐old male castrated cat was presented for dyspnoea. Cardiomegaly and pulmonary oedema were identified radiographically. Echocardiography lesions of suspected aortic dissection consisting a false lumen filled with echogenic material at the level valve insufficiency. The developed pericardial effusion chylothorax three months after initial diagnosis. A computed tomography exam revealed wall defect allowing connection between true beak‐, spiral‐shaped compressing lumen, which...
Streptococcus suis is an important pig pathogen with potential for human transmission. The serotype distributions and phenotypic characteristics vary over time among regions; however, little known about the of S. isolates in Korea. In this study, 240 collected from pigs Korea 2009-2010 were serotyped by coagglutination tests, subsequently screened three virulence-associated genes (mrp, epf sly) tested antimicrobial susceptibility. As 80 isolates, serotypes which relevant to infections,...
African swine fever (ASF), caused by virus (ASFV), is a fatal disease affecting wild and domestic pigs. Since China reported the first ASF outbreak in August 2018, ASFV has swept over neighbouring Asian countries. However, studies involving experimental pig-to-pig transmission Vietnam are lacking. The main objective of this study was to demonstrate pathobiological characteristics contact-exposed pigs estimate their basic reproduction number (R0) Vietnam. Fifteen were randomly divided into...
The aim of this study was to investigate the prevalence Giardia duodenalis in diarrhoeal faeces from calves that were reared Korea using PCR and ELISA. Diarrhoeal faecal samples collected 590 (<3 months old) throughout country November 2013 through March 2015. Data analysed according region collection, season, type diarrhoea. Of samples, 77 (13.1 per cent) 78 (13.2 cent; true 9.1 tested positive by ELISA, respectively. results both testing methods agreement 501 (84.9 with a κ value 0.34,...
This study evaluated the prevalence of Eimeria species, particularly E bovis , zuernii and auburnensis that are pathogenic to cattle, in faecal samples collected from cattle with diarrhoea reared Republic Korea by using microscopy PCR. In addition, species was analysed according age, type region, season nature diarrhoea. Overall, were identified 279 1261 (22.1 per cent) through microscopy, statistical analysis revealed a lower calves aged than three weeks or less higher haemorrhagic Of...
Giardia duodenalis is one of the most widely occurring zoonotic protozoan parasites causing diarrheal disease in calves. This study aimed to investigate prevalence G. Korean native calves and elucidate causal factors associated with giardiasis these animals. We investigated sequences three genes (ssu, bg, gdh) fecal samples collected from 792 during 2019–2020. Data were analyzed regard age, sex, sampling season, sample type (based on its physical characteristics). The screened for mentioned...
Careful cleaning and disinfection of pigpens is essential to prevent disease spread avoid the resultant economic losses. Hygiene in generally evaluated by visual monitoring supplemented with bacteriological monitoring, which includes counting total aerobic bacteria (TAB) and/or fecal indicator (FIB). However, these methods present drawbacks such as time labor requirements. As adenosine triphosphate (ATP) ubiquitous all living organisms including microorganisms, this study aimed directly...
Streptococcus dysgalactiae subspecies equisimilis (SDSE) is an emerging pathogen in animals and humans. Herein, we describe two clinical swine cases of SDSE infection presenting with lameness, neurological signs, or sudden death. Pathological examination indicated suppurative arthritis, encephalitis, multifocal abscesses kidney heart. The β-hemolytic colonies obtained from joint samples each case were identified as SDSE. isolates had low minimum inhibitory concentrations for β-lactams, they...

Raw potato starch (RPS) is resistant to digestion, escapes absorption, and metabolized by intestinal microflora in the large intestine acts as their energy source. In this study, we compared effect of different concentrations RPS on bacterial community weaned piglets.Male piglets (25-days-old, 7.03±0.49 kg) were either fed a corn/soybean-based control diet (CON, n = 6) or two treatment diets supplemented with 5% (RPS5, 4) 10% (RPS10, for 20 days fecal samples collected. The day 0 analyzed...
Abstract Salmonella Typhimurium (ST) infection in pigs poses a significant threat to animal health and food safety; the intricate mechanisms underlying host–immune responses pathogen persistence remain poorly understood. To address this knowledge gap, we comprehensively analyzed peripheral blood transcriptome piglets infected with ST. We performed histopathological evaluation, parameter analysis, advanced RNA-sequencing techniques, quantitative reverse transcription PCR (RT-qPCR)-based...
