Enterohemorrhagic Escherichia coli (EHEC), a pathogenic subset of Shiga toxin-producing E. coli (STEC), is an important cause of hemorrhagic colitis and hemolytic–uremic syndrome (HUS), and a rare cause of urinary tract infections (UTIs) with associated HUS. EHEC strains attach intimately to intestinal epithelium with formation of actin pedestals (attaching-effacing (A/E) lesions); however, the mechanism of EHEC attachment to the uroepithelium is unknown. We conducted a retrospective study on archived urinary bladder specimens from gnotobiotic piglets that naturally developed cystitis associated with EHEC O157:H7 infection following oral inoculation and fecal shedding. Paraffin-embedded bladder tissues from three piglets with cystitis and immunohistochemical …

Triggers Of Inflammatory Heart Disease, Ninaad Lasrado, Bharathi Yalaka, Jay Reddy
School of Veterinary and Biomedical Sciences: Faculty Publications
Inflammatory heart disease (IHD) is a group of diseases that includes pericarditis, myocarditis, and endocarditis. Although males appear to be more commonly affected than females, IHD can be seen in any age group. While the disease can be self-limiting leading to full recovery, affected individuals can develop chronic disease, suggesting that identification of primary triggers is critical for successful therapies. Adding to this complexity, however, is the fact that IHD can be triggered by a variety of infectious and non-infectious causes that can also occur as secondary events to primary insults. In this review, we discuss the immunological insights into …

The recently emerged Zika virus (ZIKV) spread to the Americas, causing a spectrum of congenital diseases including microcephaly in newborn and Guillain-Barré syndrome (GBS) in adults. The unprecedented nature of the epidemic and serious diseases associated with the viral infections prompted the global research community to understand the immunopathogenic mechanisms of the virus and rapidly develop safe and efficacious vaccines. This has led to a number of ZIKV vaccine candidates that have shown significant promise in human clinical trials. These candidates include nucleic acid vaccines, inactivated vaccines, viral-vectored vaccines, and attenuated vaccines. Additionally, a number of vaccine candidates have been …

Moraxella bovoculi is the most frequently isolated bacteria from the eyes of cattle with Infectious Bovine Keratoconjunctivitis (IBK), also known as bovine pinkeye. Two distinct genotypes of M. bovoculi, genotype 1 and genotype 2, were characterized after whole genome sequencing showed a large degree of single nucleotide polymorphism (SNP) diversity within the species. To date, both genotypes have been isolated from the eyes of cattle without clinical signs of IBK while only genotype 1 strains have been isolated from the eyes of cattle with clinical signs of IBK. We used 38 known genotype 1 strains and 26 known genotype …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Antimicrobial resistance has become a serious global problem and is steadily increasing worldwide. In aquaculture, there are limited antimicrobial options for treatment. Thus, there are growing needs for more specific dosing regimens of existing antimicrobial drugs that are not only to obtain therapeutic efficacy but also to minimize the resistance of pathogens. The purposes of this study were to determine pharmacokinetics (PK) of long-acting oxytetracycline (OTC) after intraperitoneal (IP) administration in Nile tilapia. One hundred and twenty healthy male tilapia (450±37.47 g) were divided into two experimental groups (60 fish/group). Each group received OTC-LA single IP injection at dosage of …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Diabetes type II were known to affect several organs in the body including bone, thus diabetes type II patients have higher risk of bone fracture. One of the important features in diabetes type II is low level of anti-inflammatory cytokine Interleukin-10 (IL-10) and gut leak condition. Both of these conditions have the role in diabetes induction, progression and exacerbation. Autogenous Mesenchymal stem cells (MSCs) have been widely utilized for enhancing bone healing treatment. Due to the diabetes condition affecting one of the most common and widely used MSCs source, the bone, this study was done to investigate the effect of …

Chulalongkorn University Theses and Dissertations (Chula ETD)
All year round, The Thai Red Cross Society received more than 100 animal samples that were suspected for rabies to be tested. Most of these animals were suspected for rabies due to the clinical signs of neurological disorder they developed before they die. Interestingly, in greater number of cases, rabies infection was ruled out as the cause of neurological disorder by direct fluorescent antibody test (dFAT). In respect to the importance of virus in the outcome of neurological disorder, this study was initiated to investigate the underlying cause of viral infection in the brain of rabies-negative cats and dogs that …
Evaluation Of Rhodococcus Equi Susceptibility To Silver Nanoparticle Antimicrobials, Elizabeth Boudaher
Evaluation Of Rhodococcus Equi Susceptibility To Silver Nanoparticle Antimicrobials, Elizabeth Boudaher
Theses and Dissertations--Veterinary Science
Rhodococcus equi is a significant cause of pneumonia in foals and immunocompromised humans. Antimicrobial resistance among R. equi isolates has developed as a consequence of inappropriate stewardship and bacterial evolution, leading to an increased rate of treatment failures that typically result in foal fatality. In the current study, we evaluated the efficacy of antimicrobial silver nanoparticle (AgNP) complexes in controlling R. equi growth. Previous studies characterizing AgNP-induced antibacterial effects in other Gram-positive pathogens led us to hypothesize that silver nanoparticle antimicrobials impact R. equi viability and intracellular replication. We therefore investigated the effect of silver nanoparticle complexes on R. equi …
Donor Age Effects On The Proliferative And Chondrogenic/Osteogenic Differentiation Performance Of Equine Bone Marrow- And Adipose Tissue Derived Mesenchymal Stem Cells In Culture, Jasmin Bagge
Theses and Dissertations--Veterinary Science
Orthopedic injuries are a major cause of lameness and morbidity in horses. Bone marrow (BM)- and adipose tissue (AT) derived mesenchymal stem cells (MSCs) have shown potential to facilitate the repair of orthopedic injuries and are being used increasingly in veterinary clinics. Presently, the use of MSCs as a therapy for equine patients is most commonly applied as autologous transplants, using BM- and AT-MSCs harvested from the patient shortly after the time of injury. Cell-based therapies are therefore delayed to enable primary cell numbers to be expanded in culture. Of concern, however, are human and rodent studies that have shown …
Host-Parasite Interaction In Horses: Mucosal Responses To Naturally Acquired Cyathostomin Infections And Anthelmintic Treatment, Ashley Elaine Steuer
Host-Parasite Interaction In Horses: Mucosal Responses To Naturally Acquired Cyathostomin Infections And Anthelmintic Treatment, Ashley Elaine Steuer
Theses and Dissertations--Veterinary Science
Cyathostomins are ubiquitous parasites in equids. In rare cases, cyathostomins lead to a generalized typhlocolitis and death. In healthy horses, local reactions are noted to the mucosal larvae; however, the mechanisms and importance of these reactions have not been elucidated. It has been hypothesized that anthelmintics can alter these reactions. Currently, three drug classes are approved for use in horses against cyathostomins; while all products target the adults, only two products are labeled as larvicidal. Adulticidal therapy is implicated in triggering the typhlocolitis, however, current evidence is contradictory. There is also conjecture that the larvicidal drugs can increase the risk …

Comparative Chondrogenesis Of Interzone And Anlagen Cells In Equine Skeletal Development, Chanhee Mok
Theses and Dissertations--Veterinary Science
At the presumptive sites of future synovial joints during mammalian skeletogenesis, articular cartilage develops from interzone located between the cartilaginous anlagen of bones. Thus, two types of cartilaginous tissues differentiate in close proximity. While anlagen cartilage is transient, progressing through endochondral ossification to form bones, articular cartilage is stable and functions throughout life to facilitate both low friction movement and load distribution. Despite important life-long functional properties, articular cartilage has a very limited intrinsic ability to repair structural defects. On the other hand, structural lesions in bones generally heal well by forming a cartilaginous callus and recapitulating endochondral ossification to …

Estimation Of Genetic Parameters For Weaning Weight Of Awassi Lambs By Using Classical And Bayesian Methods, Adi̇le Tatliyer, Si̇nan Baş
Estimation Of Genetic Parameters For Weaning Weight Of Awassi Lambs By Using Classical And Bayesian Methods, Adi̇le Tatliyer, Si̇nan Baş
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to estimate variance components and genetic parameters with six different animal models and two approaches (Bayesian and classical) on weaning weight (WW) of Awassi lambs. For this purpose, the data were obtained from Sheep and Goat Breeders' Associations of Osmaniye in Turkey. The data of 4971 progenies (from 80 rams and 1917 ewes) born between 2012 and 2016 raised under traditional conditions were evaluated. Year/season, sex, birth type, dam age, and flock size were fixed effects. All these effects except birth type were found statistically significant (P < 0.01). The overall least squares mean of weaning weight (WW) was obtained as 17.93 ± 0.05 kg. Variance components and genetic parameters were estimated by MCMC algorithms with R (for Bayesian approach) and by REML procedure with MTDFREML (for classical approach) programs. The Akaike information criterion (AIC), the log likelihood function (-2logL), and deviance information criterion (DIC) values were taken as criteria to choose the best model. Direct heritabilities of WW ranged from 0.20 to 0.35 across the models. The genetic correlation between additive genetic effect and maternal effect ranged from 0.00 to 1.00. The results were found similar across methodologies and maternal additive genetic variance resulted in lower than direct additive genetic variance. According to this study, both approaches are suitable for estimation of genetic parameters in the case of low sample size. However, the Bayesian approach, becoming increasingly popular, may be feasible to estimate variancecovariance components and genetic parameters.

Nebraska Beef Cattle Reports
A 4 yr. study was conducted to evaluate forage yield and grazing potential of double cropped annual forages following corn silage or high- moisture corn harvest. An irrigated field in a corn- soybean rotation was split in half and harvested as either corn silage or high- moisture corn, and crops were sampled to determine any effects on subsequent yield due to cover and grazing. Over the four years, steers grazing oats aft er corn silage harvest gained an average of 2.35 lb/d, while those grazing corn residue and oats aft er high- moisture corn harvest averaged 1.28 lb/d. Average oat …
