Abstract Trichophyton verrucosum causes a highly contagious disease in bovines and is occasionally transmitted to humans. Azoles are widely used as antifungal drugs bovines, act by targeting the ergosterol biosynthesis pathway. However, cases of treatment failure recurrence dermatophyte infections have been associated with mutations at drug target site. Currently, information on T. variants lacking. This study aimed classify isolated from animals exhibiting clinical symptoms cattle...
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...
Rumen cannulation is a surgical technique used to collect rumen contents from ruminants. However, surgery may potentially impact the composition of microbiota. This study aimed examine longitudinal alterations in microbiota Hanwoo steers after surgery. In this study, eight were used; four underwent (cannulation group), while remaining left intact (control group). samples collected all using stomach tubing method on day before (day 0) and postoperative days 1, 4, 7, 10, 14, 17, 21, 24, 28,...
Abstract Background Dermatophytosis is a common and major public health concern worldwide. Despite the increasing availability of antifungal drugs, relapses untreated cases dermatophyte infections are reported. Therefore, novel agents required. Aminopyrrolnitrin (APRN) shows promise for dermatophytosis treatment because its activity. Objectives This study aimed to assess properties APRN against Trichophyton verrucosum ( T . ), in both laboratory settings guinea pig model. Methods The minimum...
Summary Bovine leucocyte antigen (encoded by BoLA ) has been widely studied to identify the association with many traits related immunity. Exon2 of BoLA‐DRB 3 is extremely polymorphic, and more than 100 alleles have identified. We investigated polymorphisms BoLA‐DRB3.2 in Korean native cattle Holstein populations using a next generation sequencer GS‐FLX Titanium system. found 38 including 11 new ( BoLA‐DRB3*1303, *4702, *7101, *7501, *7201, *7301, *7601, *1104, *7701, *7401 *50021 Hanwoo,...
Prion disorder-related neurodegenerative diseases are characterized by the accumulation of prion protein (PrP) scrapie isoform (PrPsc) within central nervous system. PrPsc induces neuronal cell death increasing intracellular generation reactive oxygen species (ROS). Lactoferrin (LF) is an 80 kDa protein, which has antioxidant abilities due to scavenging ROS. The effects LF treatment on PrP (106-126)-mediated neurotoxicity and ROS were focus this study. protected against (106-126)-induced...
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...
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...
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...
Exosomes have been extensively studied as disease biomarker in humans, given their role transporting bioactive molecules. However, despite the great potential of exosomes noninvasive diagnostic markers and therapeutic nanocarriers for bovine diseases, few studies conducted on exosome. Thus, this study aimed to quantitatively qualitatively compare three isolation methods identify a suitable method serum. were isolated using ultracentrifugation alone (UC), combination size exclusion...
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...
Salmonella enterica serovar Typhimurium (ST) is one of the causative agents gastroenteritis in pigs. Pigs fed a diet supplemented with raw potato starch (RPS) have improved gut health by alteration microbiota composition and production short-chain fatty acids (SCFAs). This study aimed to evaluate effects RPS supplementation reducing infection severity fecal shedding ST-infected pigs.The weaned experimental pigs were divided into two groups: CON (n = 6) corn/soybean-based TRT 5% RPS. After 21...
(Received: March 24, 2015; Revised: April 17, Accepted: 28, 2015)Abstract : Calf losses have an economic impact on larger Korean native cattle (KNC) breeding farms due toreplacement, productivity, and marketing. However, little research KNC calf mortality or causes of death onlarge-scale has been conducted. Based medical records autopsy findings from the Hanwooexperimental station National Institute Animal Science, 2002 to 2011 were usedto identify mortality. Mortality rate calves was 5.7%....
Salmonella Typhimurium can cause gastroenteritis in weaned piglets, which are particularly vulnerable to dietary changes and dysfunction of their immature organs. The colonization S. could disrupt the gut microbiota increase susceptibility bacterium. This study aimed investigate alterations Typhimurium-infected piglets. Ten 49-day-old pigs were divided into two groups: Typhimurium-inoculated (ST, n = 6) negative control (NC, 4) groups. body weight fecal shedding monitored for 14 days after...
The objective of this study was to evaluate the duration retained placenta (RP) on postpartum diseases and culling in dairy cows.Data were collected from 456 Holstein cows between 2008 2010.RP (≥ 24 h after parturition) diagnosed by farm managers a veterinarian according standardized definitions.The overall incidence rate RP 14.0%, with fourth higher parity two times that having offspring for first time.The 2 15 days mean 6.8 days, except cases which had 10.5 days.A total 63% diseases.Among...

African swine fever, caused by fever virus (ASFV), is a highly contagious and fatal disease that poses significant threat to the global pig industry. The limited information on ASFV pathogenesis ASFV–host interactions has recently prompted numerous transcriptomic studies. However, most of these studies have focused elucidating transcriptome profiles ASFV-infected porcine alveolar macrophages in vitro. Here, we analyzed dynamic transcriptional patterns vivo nine organ tissues (spleen,...
