Egg Production, Egg Quality, And Cecal Microbial Populations Of Layersfed Diets Supplemented With Fermented Phytogenic Feed Additive, Jae Hong Park, Tae Hwa Song, Inho Kim

Turkish Journal of Veterinary & Animal Sciences

This study was undertaken to examine the effect of fermented phytogenic feed additive (FPFA) containing Gynura procumbens and Rehmannia glutinosa on egg production, egg quality, and cecal microflora population in layers. In total, 288 Hy-Line brown layers were randomly divided into 4 dietary treatment groups with 6 replicate pens per treatment group for 5 weeks. The dietary treatments were the control group (CON; basal diet without FPFA), FPFA1 (CON + 0.5% FPFA), FPFA2 (CON + 1% FPFA), and FPFA3 (CON + 2% FPFA). Egg production and egg weight during the experiment (35-39 weeks) improved linearly with the supplementation of 1% …

Serological Survey For Antibodies Against Mycobacterium Avium Complexin Hunting Dogs In East-Central Portugal, Ana Claudia Coelho, Manuela Matos, Luis Figueira, Maria De Lurdes Pinto, Juan Garcia Diez, Ana Catarina Matos

Turkish Journal of Veterinary & Animal Sciences

The Mycobacterium avium complex (MAC) causes infections and diseases in humans, birds, livestock, and wildlife, among others. In dogs, MAC infection is not frequent; however, due to its potential zoonotic characteristics, mainly in immunocompromised patients, the study of MAC epidemiology is necessary. The aim of this work was to perform a study to detect the presence of antibodies against MAC in serum samples of 53 hunting dogs in the Idanha-a-Nova municipality of East-Central Portugal. A total of 23 dogs were seropositive by commercial ELISA test (43.4%, 95% CI: 30.1%-56.7%). Factors such as age, breed, and sex were not significant. The …

Turkish Journal of Veterinary & Animal Sciences

Twenty-one Holstein bull calves (368 ± 5.2 kg) were used in order to evaluate the effects of combining recombinant bovine growth hormone (bST) and anabolic implants on growth performance and dietary energetics. Steers were assigned (7 repetitions/treatment) to individual pens (16 m2) equipped with automatic waterers and 1.2 m fence-line feed bunks. The experiment lasted 56 days. Treatments were: 1) no bST, no implant; 2) implant; and 3) bST + implant. Compared to implanted cattle, the combination of exogenous bovine somatotropin and anabolic implants did not enhance growth performance or observed dietary energy. Compared to nonimplanted cattle, anabolic implants increased …

Baylisascaris Larva Migrans, Kevin R. Kazacos

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Zoonotic diseases, such as baylisascariasis, are receiving increasing attention as components of disease emergence and resurgence (Kazacos, 2001). Baylisascariasis is caused by the roundworm Baylisascaris procyonis and is one of the more recent zoonotic disease developments. This disease remains one of the least known and poorly understood zoonotic diseases, yet over the past several decades it has become widespread. It originated in wildlife species and is now well established as a human malady. Baylisascariasis is transmitted to humans via consumption of contaminated feces, and the role of wildlife (primarily raccoons) in this transmission process is becoming more clearly known and …

In Vivo-Expressed Proteins Of Virulent Leptospira Interrogans Serovar Autumnalis N2 Elicit Strong Igm Responses Of Value In Conclusive Diagnosis, Veerapandian Raja, Santhanam Shanmughapriya, Murugesan Kanagavel, Sergey Artiushin, Sridhar Velineni, John F. Timoney, Kalimuthusamy Natarajaseenivasan

Maxwell H. Gluck Equine Research Center Faculty Publications

Leptospirosis is a serious zoonosis that is underdiagnosed because of limited access to laboratory facilities in Southeast Asia, Central and South America, and Oceania. Timely diagnosis of locally distributed serovars of high virulence is crucial for successful care and outbreak management. Using pooled patient sera, an expression gene library of a virulent Leptospira interrogans serovar Autumnalis strain N2 isolated in South India was screened. The identified genes were characterized, and the purified recombinant proteins were used as antigens in IgM enzyme-linked immunosorbent assay (ELISA) either singly or in combination. Sera (n = 118) from cases of acute leptospirosis along …

Characterization Of Rickettsial Infection Dynamics Within Dermacentor Variabilis And Amblyomma Maculatum, Emma Kate Harris

LSU Doctoral Dissertations

Spotted fever group (SFG) Rickettsia are primarily associated with their reservoir host and vector, the tick. Rickettsial colonization and maintenance within the arthropod is a key component of vector competence and pathogen transmission to the mammalian host. Contemporary detection of novel tick hosts for rickettsial species, combined with an unprecedented rise in human cases of SFG rickettsiosis, necessitates a deeper understanding of tick/Rickettsia interactions. The hypothesis for this work is that if primary tick/Rickettsia pairings do not exist then rickettsial determinants account for primary vector/pathogen relationships. To this end, Dermacentor variabilis and Amblyomma maculatum ticks were exposed to R. rickettsii, …

Development And Characterization Of A Recombinant Orf Virus Vector Expressing The Spike Protein Of Porcine Epidemic Diarrhea Virus, Kyle Hain

Electronic Theses and Dissertations

Orf virus (ORFV), the type member of the genus Parapoxvirus of the family Poxviridae, causes orf or cutaneous pustular dermatitis in sheep and goats. ORFV is a ubiquitous virus capable of re-infecting its hosts multiple times over time. ORFV causes a non-systemic, self-limiting disease which is usually restricted to the skin surrounding the virus entry sites. ORFV has evolved several immunomodulatory proteins (IMPs) that evade and/or modulate host immune responses to infection and contribute to virus virulence and disease pathogenesis. Given biological properties and unique immunomodula tor y properties, ORFV has gained significant attention in recent years for its …

Gps Tracking Of Free-Ranging Pigs To Evaluate Ring Strategies For The Control Of Cysticercosis/Taeniasis In Peru, Ian W. Pray, Dallas J. Swanson, Viterbo Ayvar, Claudio Muro, Luz Maria Moyano, Armando E. Gonzalez, Hector H. Garcia, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background Taenia solium, a parasitic cestode that affects humans and pigs, is the leading cause of preventable epilepsy in the developing world. T. solium eggs are released into the environment through the stool of humans infected with an adult intestinal tapeworm (a condition called taeniasis), and cause cysticercosis when ingested by pigs or other humans. A control strategy to intervene within high-risk foci in endemic communities has been proposed as an alternative to mass antihelminthic treatment. In this ring strategy, antihelminthic treatment is targeted to humans and pigs residing within a 100 meter radius of a pig heavily-infected with cysticercosis. …

The Role Of Nadph Oxidase 2 (Nox2) In High-Fat Diet-Induced Adiposopathy And Brain Dysfunction In A Mouse Model, Jennifer Kathleen Pepping

LSU Master's Theses

Obesity can have numerous detrimental consequences, namely metabolic syndrome, type 2 diabetes, cardiovascular disease, cancer, and Alzheimer’s disease. The pathogenesis and physiologic consequences of obesity are unknown, but they are often associated with increased inflammation and oxidative stress in both the body and in the brain. One factor that has been implicated in causing inflammation associated with a high fat diet is the enzyme NADPH oxidase, or NOX, specifically the subunit NOX2. Two studies were performed in order to assess the effects of a high fat diet in combination with a universal NOX2 deficiency and a NOX2 deficiency targeted to …

Identification And Characterization Of A Relish-Type Nf-Kb, Dvrelish In Dermacentor Variabilis, The American Dog Tick, Victoria Irene Verhoeve

LSU Doctoral Dissertations

Ticks are important worldwide as vectors of bacteria, viruses, and parasites. Pathogenic and non-pathogenic Spotted fever group (SFG) Rickettsia are maintained and transmitted by ticks with specific hard tick-Rickettsia pairings evident in nature. The pathogenic SFG Rickettsia rickettsii is transmitted by the hard tick Dermacentor variabilis. In response to infection, D. variabilis is known differentially respond to SFG Rickettsia infection. The mechanisms of differential immune induction are currently unknown, and are likely involved in the establishment of specific tick-SFG Rickettsia pairings. It was hypothesized that the level of response by D. variabilis to SFG Rickettsia occurs in a species-specific manner, …

The Ability Of Bull And Stallion Thawed Spermatozoa Refrozen Without Cryoprotectants To Activate Intra- And Interspecies Oocytes, Jose Len Yin

LSU Doctoral Dissertations

Semen cryopreservation has allowed the establishment of genome banks and the large scale propagation of species. The development of simple techniques to cryopreserve semen or alternatives to efficiently use cryopreserved semen from males of valuable genetics that have become infertile will permit continuous propagation of the genetics from these males and may serve as a model for preservation and propagation of endangered species. Sperm cryopreservation without cryoprotectants is a simple process, and offspring have been produced following intracytoplasmic sperm injection (ICSI); however the ability of frozen-thawed sperm refrozen without the addition of cryoprotectants to activate oocytes following ICSI was unknown. …

Rickettsia Felis, Transmission Mechanisms Of An Emerging Flea-Borne Rickettsiosis, Lisa Diane Brown

LSU Doctoral Dissertations

Rickettsia felis is an emerging insect-borne rickettsial pathogen and the causative agent of flea-borne spotted fever. First described as a human pathogen from the United States in 1991, R. felis is now identified throughout the world and considered a common cause of fever in Africa. The cosmopolitan distribution of this pathogen is credited to the equally widespread occurrence of cat fleas (Ctenocephalides felis), the primary vector and reservoir of R. felis. Additionally, R. felis has been identified in other hematophagous arthropods (including numerous species of fleas, ticks, mosquitoes, and mites). Most transmission cycles of pathogenic Rickettsia include transovarial and transstadial …
