Effects Of Relative Humidity On Meat Quality In Dry Aged Beef, Felipe A. Ribeiro, Soon K. Lau, Morgan L. Henriott, Nicolas J. Herrera, Nicolas A. Bland, Jeyamkondan Subbiah, Chris Calkins

Nebraska Beef Cattle Reports

During dry- aging, water is transferred from the interior to the meat surface and is subsequently evaporated to the surrounding environment. Th ere is a common belief in the meat industry that rapid drying creates a hard crust on the meat surface, which would act as a protective barrier against moisture loss, holding moisture on the inside of the product. Th is phenomenon is called case hardening. If this hypothesis is correct, drying at low relative humidity would be recommended in order to get case hardening and avoid excessive yield loss. Th is study was conducted to evaluate the effects …

Intimate Attachment Of Escherichia Coli O157:H7 To Urinary Bladder Epithelium In The Gnotobiotic Piglet Model, Rodney A. Moxley, Tom W. Bargar, Stephen D. Kachman, Diane R. Baker, David H. Francis

School of Veterinary and Biomedical Sciences: Faculty Publications

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 …

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 …

Osteogenic Differentiation Potential By Mouse Bone Marrow-Derived Mesenchymal Stemcells (Mbm-Mscs) Derived From Gut Leak-Induced Diabetes Type Ii Mouse Model, Nabila Syarifah Jamilah

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 …

Genetic And Pathological Investigations Of Viruses In Rabies-Negative Brain Of Cats And Dogs, Sabrina Wahyu Wardhani

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

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

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 …
