Role Of Viral And Host Factors In Influenza Virus Mediated Inhibition Of Interleukin-23, Ashish Tiwari Jan 2014

Role Of Viral And Host Factors In Influenza Virus Mediated Inhibition Of Interleukin-23, Ashish Tiwari

Theses and Dissertations--Veterinary Science

Influenza virus is one of the major respiratory pathogens of humans as well as animals, including equines. There is an increasing evidence that bacterial infections are the most common cause of the death during influenza. In horses also, secondary bacterial pneumonia can lead to death, and surviving horses may take up to six months for the complete recovery resulting in heavy economic loss to the equine industry. Interleukin (IL)-23 mediated innate immune response has been shown to protect the host from various respiratory bacterial infections. However, studies to investigate the role of host and viral factors in the regulation of …

Examination Of The Snsag Surface Antigen Gene Family In Sarcocystis Neurona, Ablesh Gautam Jan 2014

Examination Of The Snsag Surface Antigen Gene Family In Sarcocystis Neurona, Ablesh Gautam

Theses and Dissertations--Veterinary Science

Sarcocystis neurona is a protozoan parasite that causes the serious neurologic disease equine protozoal myeloencephalitis (EPM). The life cycle of S. neurona progresses through multiple developmental stages that differ morphologically and molecularly. The S. neurona merozoite surface is covered by multiple related proteins, which are orthologous to the surface antigen (SAG) gene family of Toxoplasma gondii. The SAG surface antigens in T. gondii and another related parasite Neospora caninum are life cycle stage-specific and seem necessary for parasite transmission and persistence of infection. The present research was conducted to explore the gene family of SnSAGs in S. …

Studies On Equine Placentitis, Igor Frederico Canisso Jan 2014

Studies On Equine Placentitis, Igor Frederico Canisso

Theses and Dissertations--Veterinary Science

Two types of placentitis were studied: ascending and nocardioform placentitis. Although the first diagnosis of nocardioform placentitis was made three decades ago, little is known about the disease, due to the lack of an experimental model. In attempt to develop a research model, Crossiela equi was inoculated through intrauterine, intravenous, intrapharyngeal, and oral routes, but none of the routes resulted in nocardioform placentitis. This may indicate that unidentified factors may play a role in disease pathogenesis and that simple presence of bacteria is not sufficient to induce nocardioform placentitis. The second and major component of this dissertation involved the identification …

Mechanisms Of Innate Immunity In Polymicrobial Sepsis, Liliang Jin Jan 2014

Mechanisms Of Innate Immunity In Polymicrobial Sepsis, Liliang Jin

LSU Doctoral Dissertations

Severe bacterial sepsis leads to a pro-inflammatory condition that can manifest as septic shock, multiple organ failure, and death. Neutrophils are critical for the rapid elimination of bacteria, however, the role of neutrophil chemoattractant CXCL1, pattern recognition receptors (PRRs)- NLR protein 3 (NLRP3) and alcohol in bacterial clearance during sepsis remains elusive. We demonstrate that CXCL1 plays a pivotal role in mediating host defense to polymicrobial sepsis following cecal ligation and puncture (CLP) in gene-deficient mice. CXCL1 appears to be essential for restricting bacterial outgrowth and preventing multiple organ failure and death in mice. Moreover, CXCL1 is essential for neutrophil …

The Role Of Viral Glycoproteins And Tegument Proteins In Herpes Simplex Virus Type 1 Cytoplasmic Virion Envelopment, Dmitry Vladimirovich Chouljenko Jan 2014

The Role Of Viral Glycoproteins And Tegument Proteins In Herpes Simplex Virus Type 1 Cytoplasmic Virion Envelopment, Dmitry Vladimirovich Chouljenko

LSU Doctoral Dissertations

Herpes simplex virus type 1 (HSV-1) is a ubiquitous neurotropic alphaherpesvirus transmitted by contact with mucocutaneous surfaces of infected individuals. HSV-1 enters the host by fusion of the viral envelope with the host cell plasma membrane, followed by translocation of the viral capsids to the nucleus where viral DNA is injected into the host cell nucleus to initiate viral replication. To generate infectious virions, newly assembled capsids travel to the cytoplasm and undergo a process called secondary envelopment by budding into cytoplasmic vesicles derived from the trans-Golgi network. Cytoplasmic envelopment is a complex process involving interactions between a multitude of …

Relationships Between Equine Management Practices And Intestinal Parasite Infection, Abigail Pagel Jan 2014

Relationships Between Equine Management Practices And Intestinal Parasite Infection, Abigail Pagel

Honors Projects

Parasitology is an important area of veterinary medicine, but the risk factors for high parasite loads are not well-understood. Equine intestinal parasites can cause extensive disease and death. In the current study, the relationship between equine intestinal parasite loads and adherence to veterinary guidelines for equine management practices was studied. Satisfactory adherence to guidelines regarding food, pasture, and flooding management was related to lower parasite loads. Adherence to guidelines regarding deworming, quarantine, bedding, and water did not appear to lower parasite loads. Still, adhering to these guidelines has been shown to improve equine welfare, even if they are not related …

The Role Of Monocyte Chemoattractant Protein-1 In Innate Immunity Against Methicillin Resistant Staphylococcus Aureus Pneumonia, Mary Katherine Leissinger Jan 2014

The Role Of Monocyte Chemoattractant Protein-1 In Innate Immunity Against Methicillin Resistant Staphylococcus Aureus Pneumonia, Mary Katherine Leissinger

LSU Master's Theses

Monocyte chemoattractant protein-1 is critical for monocyte recruitment to the lungs in response to bacterial infection. MCP-1 is also essential for protective neutrophil recruitment to the lungs during Escherichia coli and Klebsiella pneumoniae infection. Staphylococcus aureus pneumonia, specifically strain USA300, carries a high morbidity and mortality rate and is an important pathogen in hospital/ventilator and community acquired pneumonia. In the current study, we investigated the role of MCP-1 in pulmonary innate immunity to S. aureus in C57Bl/6, MCP-1-/- and MCP-1 AB blocked mice. As compared to C57Bl/6, MCP-1-/- mice showed increased concentrations of neutrophils in the airways and lung parenchyma …

Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao Jan 2014

Cardiovascular Tolerance And Safety Of Intravenous Lidocaine In The Broiler Chicken (Gallus Gallus Domesticus), Joao Manuel Lemos Brandao

LSU Master's Theses

Lidocaine, an amide local anesthetic agent, is commonly used in mammals, including humans. There is a general assumption that birds are more sensitive to lidocaine than mammals. Relatively low doses of lidocaine have been suggested to cause toxic effects in birds. While this information appears to be anecdotal, it has been perpetuated in the literature. The overall objective of this thesis research was to determine the tolerance and safety of intravenous lidocaine in broiler chickens. To assess the cardiovascular effects of lidocaine, relative changes on heart rate and mean blood pressure were calculated. Clinically significant cardiovascular effects were defined as …

Nebraska Beef Cattle Reports

Individually fed cattle were adapted to high grain diets with a traditional grain adaptation program or one of two RAMP® adaptation programs. RAMP programs adapted cattle to a finishing diet gradually over 28 days in four steps or directly without an adaptation. Feed intake variance among d was greater for traditionally adapted cattle compared to either RAMP program, but DMI was not different during the adaptation period. Over the 138-day period, feedlot performance and carcass traits were not affected by adaptation treatment. Cattle fed RAMP for 10 days can be transitioned to a finishing ration containing 47.5% Sweet Bran …

Comparison Of Long-Term Progestin-Based Synchronization Protocols On Fixed-Time Ai Pregnancy Rate In Beef Heifers, Rebecca A. Vraspir, Adam F. Summers, Doug O'Hare Hare, Larry D. Rowden, Rick N. Funston

Nebraska Beef Cattle Reports

Yearling Angus heifers at a commercial ranch in the Nebraska Sandhills were randomly assigned to one of two progestin-based fixed-time AI protocols (MGA or 14-day CIDR) to compare pregnancy rates. Heifers had similar fixed-time AI pregnancy rates between MGA and 14-day CIDR. A similar proportion of MGA and 14-day CIDR heifers displayed a second estrus; however, heifers previously synchronized with MGA tended to have a greater second AI pregnancy rate. Overall pregnancy rate was similar between MGA and 14-day CIDR treatments. The MGA system was the more cost effective synchronization protocol in this study.

Differences In Fecal Bacterial Community Composition Between Beef Steers Which Are High-Shedders And Low-Shedders Of Shiga Toxin-Producing Escherichia Coli (Stec), Nirosh D. Aluthge, Yoshitha A. Wanniarachchi, Brandon L. Nuttelman Nuttelman, Cody J. Schneider, Terry J. Klopfenstein, Galen E. Erickson, Samodha C. Fernando Jan 2014

Differences In Fecal Bacterial Community Composition Between Beef Steers Which Are High-Shedders And Low-Shedders Of Shiga Toxin-Producing Escherichia Coli (Stec), Nirosh D. Aluthge, Yoshitha A. Wanniarachchi, Brandon L. Nuttelman Nuttelman, Cody J. Schneider, Terry J. Klopfenstein, Galen E. Erickson, Samodha C. Fernando

Nebraska Beef Cattle Reports

The community composition of the fecal microbiota was compared between beef steers which were high-shedders and low-shedders of Shiga toxin-producing Escherichia coli. Based on Shannon and Chao 1 diversity indices, the high-shedders had a more diverse fecal bacterial community than the low-shedding steers. Members of the genus Prevotella were observed as being more abundant in the low-shedders compared to the high-shedders, while Succinivibrio were more abundant in the high-shedders. Isolation of specific bacteria which are significantly more abundant in low-shedders may pave the way to developing direct-fed microbials which are effective in reducing STEC shedding among high-shedding beef steers.

Optimal Marketing Date Of Steers Depends On Marketing Strategy, James C. Macdonald, Cody J. Schneider, Kelsey M. Rolfe Rolfe, Stephen D. Kachman, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Seven research trials conducted over five years at the University of Nebraska–Lincoln were summarized to determine how animal performance changes through the finishing period on a live and carcass weight basis. Live weight, carcass weight, carcass ADG, and carcass feed efficiency all changed quadratically throughout the feeding period; live ADG and live feed efficiency declined linearly. During times of negative profit margins, optimal profitability for steers marketed on a live-basis occurred by selling early, whereas optimal profitability was achieved by feeding steers marketed on a carcass-basis longer.

Turkish Journal of Veterinary & Animal Sciences

To determine sequence characteristics and phylogenetic relationships of the nonstructural (NS) gene, the NS genes of 9 avian influenza (AI) viruses were sequenced and compared with other Iranian AI H9N2 viruses available in GenBank. The similarity among the earliest Iranian H9N2 isolate (A/chicken/Iran/ZMT-101/1998) and recent (2007–2011) studied isolates was low (94%). Some of the studied viruses revealed substitutions in RNA-binding and effector domains as well as antigenic regions of the NS protein. Recently studied isolates have a high similarity (97.4%-98.7%) with some Pakistani isolates (like A/chicken/Sawabi/NARC-2434/2006) in the NS gene. In the phylogenetic analysis, recently studied isolates composed a cluster …

Estimation Of Genetic And Phenotypic Parameters For Daily Milk Yield Of Black Bengal Does, Md. Mohan Mia, Mobarak Akter Md. Yahia Khandoker, Syed Sakhawat Husain, Md. Omar Faruque, David Russell Notter

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the genetic and phenotypic parameters for daily milk yield (DMY) in Black Bengal does. Genetic parameters were estimated using a residual maximum likelihood procedure, fitting an animal model while ignoring maternal genetic or permanent environmental effects. The least squares mean for DMY was 354.76 g. DMY was significantly (P < 0.01) affected by parity, litter size, and season of kidding. The heritability of DMY was low (0.15) and the fact that the trait can only be measured in females suggests that progeny testing may be the best sire selection method for this trait.
