Seroprevalence And Molecular Investigation Of Brucellosis In Camels Of Selected Districts Of Punjab, Pakistan, Asim Shahzad, Ahrar Khan, Muhammad Zargham Khan, Muhammad Saqib

The Thai Journal of Veterinary Medicine

Camels still play an important role in providing food security in several developing countries, especially in the arid zones. As brucellosis has zoonotic importance, thereby diseased camels can infect humans chiefly via milk. In spite of its vital importance, limited studies are available of brucellosis in camels in Pakistan. Keeping in view the fact, this study was designed and executed. For this purpose, serum samples (n=761) from various herds of camel with history of abortion from different locations of Punjab province, Pakistan were collected. Initial screening was done using Rose Bengal plate test (RBPT). To avoid improper judgment of the …

Surgical Treatment Of Spontaneous Pneumothorax Associated With Lobal Emphysema In A Dog, Yawon Hwang, Seungwon Yoo, Gonhyung Kim

The Thai Journal of Veterinary Medicine

A 3-year-old female Maltese dog was admitted with cough, dyspnea, and gasping. There was no sign of trauma in history taking. It was speculated that pneumothorax occurred in the right pleural space after X-ray examination. Thoracocentesis and chest tube were applied for 5 days. The symptoms of dyspnea and cough were, however, not relieved or recurred. Exploratory thoracotomy was considered to be the most appropriate approach. Spongiform and air-containing tissue was identified in the whole parenchyma in the right middle lobe. Total lobectomy was performed and then a chest tube was inserted. Atrophy of the right cranial lobe and collapse …

The Thai Journal of Veterinary Medicine

In the present study the effect of antimicrobial peptide K9CATH was evaluated in a murine model of mastitis by Staphylococcus aureus. Mastitis was induced with a clinical isolate of S. aureus in 20 female Balb/c mice at 7 to 10 days of lactation. Ten mice (treatment group) received daily intramammary infusions of 32 μg/50 μL K9CATH peptide, for 3 consecutive days, and 10 other mice (control group) received only 50 μL of saline solution. Results showed a significant reduction (P<0.01) in S. aureus CFU counts in the treatment group compared to the control group. These data suggest that the K9CATH peptide could be a potential candidate for the treatment of bovine mastitis.

Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan

Graduate Theses and Dissertations

It is well known that arginine vasotocin (AVT) in birds is involved in physiological homeostasis such as cardiovascular, osmotic regulation as well as reproductive functions. Pertinent to these physiological functions, AVT immunoreactive (-ir) neurons in the hypothalamus have been found associated with hemorrhage, dehydration, oviposition and other physiological regulation. Evidence, however, suggests that AVT also plays significant roles in modulating behavior, memory, stress, and food intake. This dissertation research addresses the latter two neuroendocrine functions of AVT in detail within the chicken brain. First, the functional role of AVT-ir neurons in conjunction with corticotropin releasing hormone (CRH)-ir neurons in the …

Reduction In Activity By Noxious Chemical Stimulation Is Ameliorated By Immersion In Analgesic Drugs In Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Waleed Al-Nuaimy, Lynne U. Sneddon

Anesthesia and Analgesia Collection

Research has recently demonstrated that larval zebrafish show similar molecular responses to nociception to those of adults. Our study explored whether unprotected larval zebrafish exhibited altered behaviour after exposure to noxious chemicals and screened a range of analgesic drugs to determine their efficacy to reduce these responses. This approach aimed to validate larval zebrafish as a reliable replacement for adults as well as providing a high-throughput means of analysing behavioural responses. Zebrafish at 5 days postfertilization were exposed to known noxious stimuli: acetic acid (0.01%, 0.1% and 0.25%) and citric acid (0.1%, 1% and 5%). The behavioural response of each …

Maxwell H. Gluck Equine Research Center Faculty Publications

Background: ELISAs are known to have a higher diagnostic sensitivity than the agar gel immunodiffusion (AGID) when employed for serological diagnosis of equine infectious anaemia (EIA). For this purpose, an “in-house” and five commercial ELISAs available in Italy were assessed by the National Reference Centre for EIA for their analytic specificity (Sp); precocity, defined as capability of detecting first antibodies produced during a new infection; precision based on repeatability and reproducibility, estimated from the coefficient of variation (CV); accuracy, estimated from multiple K and relative Sp and sensitivity (Se). Two serum panels, positive for non-equine retroviruses and the most frequent …

The Use Of Papain And Benzyl Isothiocyanate As Anthelmintics For Equine Strongyles, Abigail Maxey

Undergraduate Honors Thesis Projects

Seeds of Carica papaya L. (Caricaceae) are a promising source of investigation for a novel anthelmintic to treat equine strongyle infestation. Strongyles are small redworms that attach to the intestinal wall in the equine. They can cause colic, poor hair coat, poor body condition, and, in severe cases, death. The objective of this study was to determine if benzyl isothiocyanate (BITC) and papain, two compounds found in papaya seeds, could be used to prevent migration of third stage cyathostome larvae (L3) in vitro using larval migration inhibition assays. The assays involved incubating larvae in solution, followed by larval migration through …

Evaluation Of Circulating Mirnas During Late Pregnancy In The Mare, Shavahn C. Loux, Kirsten E. Scoggin, Jason E. Bruemmer, Igor F. Canisso, Mats H. T. Troedsson, Edward L. Squires, Barry A. Ball

Veterinary Science Faculty Publications

MicroRNAs (miRNAs) are small, non-coding RNAs which are produced throughout the body. Individual tissues tend to have a specific expression profile and excrete many of these miRNAs into circulation. These circulating miRNAs may be diagnostically valuable biomarkers for assessing the presence of disease while minimizing invasive testing. In women, numerous circulating miRNAs have been identified which change significantly during pregnancy-related complications (e.g. chorioamnionitis, eclampsia, recurrent pregnancy loss); however, no prior work has been done in this area in the horse. To identify pregnancy-specific miRNAs, we collected serial whole blood samples in pregnant mares at 8, 9, 10 m of gestation …

Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa

Biology: Student Scholarship & Creative Works

The focus of this paper is to describe a typical Trap-Neuter-Return (TNR) program and highlight the major pros and cons surrounding this somewhat controversial method of managing the overwhelming free-roaming cat population. The effects of the species’ overabundance on the environment and human health are also discussed. Citing studies completed on TNR programs around the globe as well as mathematical models, the effectiveness of this method is compared to other, currently used alternatives. Finally, it has been suggested that the general awareness level a neighborhood possesses about the true goals of TNR programs has a potentially significant impact on the …

Bioelectrics Publications

Ebola virus (EBOV) is an extremely contagious pathogen and causes lethal hemorrhagic fever disease in man and animals. The recently occurred Ebola virus disease (EVD) outbreaks in the West African countries have categorized it as an international health concern. For the virus maintenance and transmission, the non-human primates and reservoir hosts like fruit bats have played a vital role. For curbing the disease timely, we need effective therapeutics/prophylactics, however, in the absence of any approved vaccine, timely diagnosis and monitoring of EBOV remains of utmost importance. The technologically advanced vaccines like a viral-vectored vaccine, DNA vaccine and virus-like particles are …

Animal and Food Sciences Faculty Publications

Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species. This study was conducted to determine the effect of exogenous lactobacilli on pH and the growth of amylolytic and lactate-utilizing bacteria. Feces were collected from 3 mature geldings fed grass hay with access to pasture. Fecal microbes were harvested by differential centrifugation, washed, and re-suspended in anaerobic media containing ground corn, wheat, or oats at 1.6% (w/v) starch and one of five …
