Molecular Characterization And Antibiogram Of Riemerella Anatipestifer In Ducklings In Upper Egypt, Mohamed Sabry Ahmed, Amal Abd El-Ghani Batahi, Ahmed Ibrahim Ahmed, Nabila Osman

The Thai Journal of Veterinary Medicine

Riemerella anatipestifer infection represents a great threat to the duck industry worldwide and it is considered the major cause of death in the backyard rearing system of ducks in Egypt. The disease is characterized by diarrhea, respiratory signs and loss of weight. The present study was conducted during the period between July 2019 and January 2021 to examine the prevalence rate, the antibiogram patterns of the different antibiotics and the pathogenicity of R. anatipestifer in Qena province. One-hundred samples were collected from diseased and freshly dead backyard ducklings. A tentative characterization of R. anatipestifer was done depending on the phenotypic …

A History Of The Development Of Alternatives To Animals In Research And Testing, John Parascandola

New Directions in the Human-Animal Bond

Growing public interest in animal welfare issues in recent decades has prompted increased attention to the efforts to develop alternative, nonanimal methods for use in biomedical research and product testing. In A History of the Development of Alternatives to Animals in Research and Testing, the first book-length study of the subject, John Parascandola traces the history of the concept of alternatives to the use of animals in research and testing in Britain and the United States from its beginnings until it had become firmly established in the scientific and animal protection communities by the end of the 1980s. This …

A Potential Of Watercress Nasturtium Officinale Bioactive Compounds In Inhibiting Infectious Myonecrosis Virus (Imnv) By Targeting Rna-Dependent Rna Polymerase (Rdrp) Virus From Several Countries: In Silico Approach, Qurrota A’Yunin, Fatchiyah Fatchiyah, Maftuch Maftuch, Feri Eko Hermanto, Muhammad Hermawan Widyananda, Narendra Santika Hartana, Muhaimin Rifa’I, Yoga Dwi Jatmiko

Karbala International Journal of Modern Science

Infectious myonecrosis virus (IMNV) disease causes mass mortality and decreased shrimp production. The RdRp region projects to the interior, where it may function in transcription. The focus of this study was to determine the effect of amino acid polymorphisms from several countries on the structure of RdRp and identify the potential of watercress in inhibiting IMNV by targeting the RdRp protein of IMNV through an in silico approach. The results showed that the structure of the IMNV RdRp protein from Indonesia was similar to Mexico, and the protein structure from India_QDN was identical to India_QIL. Ligand binding affinity values showed …

Evaluation Of Residual Antibacterial Effects On Canine Skin Surface And Hairs Following Treatment With Five Commercial Mousse Products Against Staphylococcus Pseudintermedius In Vitro, Chi-Yen Wu

LSU Master's Theses

Topical products are essential treatments for canine superficial bacterial folliculitis. However, studies for commercial products typically evaluate antibacterial effects on hairs rather than the skin surface. In addition, the interference from the hair length has not been evaluated in these studies. Therefore, the study objective for this study was to evaluate the residual antibacterial effects of five mousse products, (1) 2% chlorhexidine and 2% miconazole, (2) 0.05% phytosphingosine, (3) 2% salicylic acid and 10% ethyl lactate, (4) 3% chlorhexidine and 0.5% climbazole, and (5) 2% chlorhexidine and 1% ketoconazole on both the skin surface and hairs in both short- and …

Reversible Downregulation Of Hypothalamic-Pituitary-Gonadal Axis In The Stallion With A Third-Generation Gnrh Antagonist, Gabriel Monteiro Davolli

Theses and Dissertations--Veterinary Science

The objectives of this thesis were: (1) to evaluate the downregulation of the stallion hypothalamic-pituitary-gonadal (HPG) axis by a GnRH antagonist (acyline) based upon endocrine, seminal, testicular and behavioral effects, and (2) to assess recovery after treatment. Stallions were treated for 50 days (n=4; 330µg/kg acyline q 5d) and controls (n=4) received vehicle alone. Stallions were assessed pre-treatment and for 72 days after last treatment. Treatment induced declines (p<0.05) in FSH, LH, testosterone (to castrate levels) and estrone sulfate. Gonadotropins and testosterone returned to control values within nine days and estrone sulfate by 14 days after treatment discontinuation. Acyline-treated stallions failed to respond with FSH, LH and testosterone increase after exogenous GnRH stimulation (25µg gonadorelin, IV) compared to pre-treatment and control stimulation. Total sperm numbers and motility were reduced in acyline-treated stallions, as well as total seminal plasma protein and testicular volume (p<0.05). Time to ejaculation was increased in acyline group (p<0.5). Testicular, sexual behavior and most seminal parameters regained normal levels within 72 days after treatment ceased. Sperm output of acyline-treated stallions was regained within seven months after ending treatment. Acyline reversibly suppressed the stallion HPG axis, thus has potential for treating the androgen-dependent Equine-Arteritis-Virus carrier state and as behavior modulator.

A Prevalence Study Of Southeast Origin Sale Barn Beef Cattle, Comingled In Warren County, Kentucky, Persistently Infected With Bovine Viral Diarrhea Virus, Including The Effects Of Season And Body Weight, Sarah Elizabeth Thomas

Masters Theses & Specialist Projects

Bovine viral diarrhea (BVD) is an economically important disease of cattle. Calves persistently infected (PI) with the bovine viral diarrhea virus (BVDV) are a powerful agent for spread of the virus. A total of 24,423 southeast origin beef cattle comingled at three Warren County, Kentucky locations were tested from November 2007 to June 2010 for PI BVDV. A total of 97 head tested positive for PI BVDV, giving an average overall prevalence of 0.397%.
Calves tested were subdivided into categories for additional calculations of dependence. A total of 8,910 were categorized by weight range upon testing (300-399 lbs, 400-499 lbs, …
