Ostrich As A Possible Source Of Pathogenic Strains Of Clostridium Difficile, Seyed Mohsen Jafari, Gholamali Kalidari, Seyed Mostafa Peighambari, Jamshid Razmyar

The Thai Journal of Veterinary Medicine

Clostridium difficile (C. difficile) is known as the most important causative agent of antibiotic-associated pseudomembranous colitis in human. According to recent studies, food animals, especially poultry, are known as carriers for toxin harboring C. difficile. Since ostrich farming is a growing industry in Iran, the characterization and genotyping of C. difficile isolates in ostriches are very important for public health. A total of 100 fecal samples were collected from 10 ostrich farms located in the north-east of Khorasan Razavi province, Iran. The samples were cultured anaerobically. Multiplex PCR was applied in order to detect tcdB, tcdA, cdtA and cdtB genes …

Identification Of Mycobacteria From Unhealthy And Apparently Healthy Aquarium Fish Using Both Conventional And Pcr Analyses Of Hsp65 Gene, Mahdi Seyfahmadi, Seyyed Reza Moaddab, Azar Sabokbar

The Thai Journal of Veterinary Medicine

Seventy-eight unhealthy and forty-two apparently healthy looking freshwater aquarium fish belonging to twenty-six different species were collected from local aquarium stores in different cities and were investigated for the presence of mycobacteria in north-western Iran by culture and molecular methods. Using the culture method, Mycobacterium sp. was isolated from 31.6% of the fish (38 cases), while it was obtained in 30.8% (37 cases) by polymerase chain reaction (PCR) assay for a 439 bp fragment of the heat shock protein 65kD gene (hsp65). Acid-fast bacilli (AFB) were seen on the smears of 27 samples (22.5%) by direct microscopic examination method of …

Effects Of Centrifugation And Removal Of Seminal Plasma On Motility Of Fresh Boar Sperm, Olivia Bury, Victoria Mcrae, Jose Len, Kate Plush, Roy N. Kirkwood

The Thai Journal of Veterinary Medicine

Extended semen from 6 boars was centrifuged and then gently resuspended (CR), had the supernatant decanted to remove residual seminal plasma and resuspended in new extender (CD), or served as non-treated controls. Measures of sperm motility were assessed immediately after centrifugation and then every 24 h until 96 h using a computer-assisted sperm analyser. Total and progressive sperm motilities were reduced (P<0.05) by 48 h in CD. Total motility was not affected in CR sperm but progressive motility was reduced (P<0.05) at 72 h. Changes with time were very similar for VSL, VAP, VCL and BCF. Control values remained relatively stable but VCL, VSL, VAP and ALH were lower within minutes of centrifugation and decanting of CD sperm. Both CR and CD treatment values for all variables were lower (P<0.05) from 3 d. These data indicate that centrifugation can negatively affect boar sperm motility and that even the small amount of residual seminal plasma in fresh-extended boar semen has a protective role. Sperm age-associated reduced motility can be countered with caffeine.

Sahoo, Ezhumalai Muthukrishnan, Sathish Kumar Natarajan, David Steffen, Hiep Vu, Gustavo A. Delhon, Fernando Osorio, Thomas M. Petro, Shi-Hua Xiang, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

ABSTRACT Zika virus (ZIKV), a mosquito-transmitted flavivirus responsible for sporadic outbreaks of mild and febrile illness in Africa and Asia, reemerged in the last decade causing serious human diseases, including microcephaly, congenital malformations, and Guillain-Barré syndrome. Although genomic and phylogenetic analyses suggest that genetic evolution may have led to the enhanced virulence of ZIKV, experimental evidence supporting the role of specific genetic changes in virulence is currently lacking. One sequence motif, VNDT, containing an N-linked glycosylation site in the envelope (E) protein, is polymorphic; it is absent in many of the African isolates but present in all isolates from the …

Effects Of Monosodium Glutamate On Heart Beat And The Embryonic Development Of Zebrafish, Naowarat Suthamnatpong, Aranya Ponpornpisit

The Thai Journal of Veterinary Medicine

The effect of monosodium glutamate (MSG) on zebrafish, Danio rerio, embryo was investigated at different concentrations of ten-fold dilution of ten times lesser than the median lethal concentration (LC50). Zebrafish embryos in the MSG treated groups (40,000 ppm and 80,000 ppm) reached highest mortality rate at 100 % within 48 hpf and 96 hpf which is significantly different (p<0.05) from negative control group. According to the Probit analysis, the LC50 of MSG on zebrafish embryo at 48 hpf and 96 hpf were 15,200 ppm and 10,300 ppm, respectively. Under the observation, effects based on the toxicity endpoint composed of lethal, sublethal and malformation effects appeared within 144 hpf. Exposure to MSG at 1,500 ppm and 150 ppm significantly produced sublethal effects and malformation development to zebrafish embryo. MSG induced cardiotoxic effects in zebrafish embryo was observed at 15, 150 and 1,500 ppm. Our results demonstrate that zebra fish embryo is a good model for the detection of toxic potential of chemical substances. Also, our data suggest the need to reconsider the safety of MSG and elucidate its mechanism of adverse reaction in further studies.

Development Of An Animal Model For Enterovirus For Evaluation D68 For Screening Of Antiviral Therapies, W. Joseph Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enterovirus D68 (EV-D68) virus has become more prevalent over the last 15 to 20 years. EV-D68 attacks the respiratory system and can cause severe disease in individuals who have underlying respiratory problems. There have also been reports of individuals with EV-D68 showing signs of neurological system problems and acute flaccid paralysis. Because of the increase in patients with EV-D68 and also the potential for neurological disease, an animal model is needed to study the disease and to evaluate experimental therapies for EV-D68 infection.

To develop the animal model, 4-week old AG129 mice that lack alpha and beta interferon receptors, making …

Genetic Signatures For Helicobacter Pylori Strains Of West African Origin, Kennady K. Bullock, Carrie L. Shaffer, Andrew W. Brooks, Ousman Secka, Mark H. Forsyth, Mark S. Mcclain, Timothy L. Cover

Veterinary Science Faculty Publications

Helicobacter pylori is a genetically diverse bacterial species that colonizes the stomach in about half of the human population. Most persons colonized by H. pylori remain asymptomatic, but the presence of this organism is a risk factor for gastric cancer. Multiple populations and subpopulations of H. pylori with distinct geographic distributions are recognized. Genetic differences among these populations might be a factor underlying geographic variation in gastric cancer incidence. Relatively little is known about the genomic features of African H. pylori strains compared to other populations of strains. In this study, we first analyzed the genomes of …

The inner membrane complex (IMC) of apicomplexan parasites contains a network of intermediate filament-like proteins. The 14 alveolin domain-containing IMC proteins in Toxoplasma gondii fall into different groups defined by their distinct spatiotemporal dynamics during the internal budding process of tachyzoites. Here, we analyzed representatives of different IMC protein groups across all stages of the Toxoplasma life cycle and during Sarcocystis neurona asexual development. We found that across asexually dividing Toxoplasma stages, IMC7 is present exclusively in the mother’s cytoskeleton, whereas IMC1 and IMC3 are both present in mother and daughter cytoskeletons (IMC3 is strongly enriched in daughter buds). In …

Symptoms And Causes Of Foamy Bloat In Cattle, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The bovine stomach normally produces gases such as ammonia, carbon dioxide and methane. However when these gases become trapped in the bovine stomach because of a thick, frothy or foamy liquid it is called bloat. Cattle bloat is a very old condition and goes by many names but is primarily trapped gas within the bovine stomach. Readily digested feedstuff such as highly processed grain diets or an overabundance of fresh immature alfalfa often leads to a vast amount of small particles and carbohydrates in the rumen; this is the major cause of foamy bloat. Severe bloat causes death by suffocation …

Canisso, Lakshman Chelvarajan, Casey L. Edwards, Bora Nam, John F. Timoney, Peter J. Timoney, Udeni B. R. Balasuriya

Maxwell H. Gluck Equine Research Center Faculty Publications

Equine arteritis virus (EAV) has the ability to establish persistent infection in the reproductive tract of the stallion (carrier) and is continuously shed in its semen. We have recently demonstrated that EAV persists within stromal cells and a subset of lymphocytes in the stallion accessory sex glands in the presence of a significant local inflammatory response. In the present study, we demonstrated that EAV elicits a mucosal antibody response in the reproductive tract during persistent infection with homing of plasma cells into accessory sex glands. The EAV-specific immunoglobulin isotypes in seminal plasma included IgA, IgG1, IgG3/5, and IgG4/7. Interestingly, seminal …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …

Genomic Selection And Its Application In Animal Breeding, Fahar Ibtisham, Li Zhang, Mei Xiao, Lilong An, Muhammad Bilal Ramzan, Aamir Nawab, Yi Zhao, Guanghui Li, Yingmei Xu

The Thai Journal of Veterinary Medicine

A significant gap exists between animal production and world’s population demand. Although conventional breeding methods have been effectual for selection of animal populations on many traits of economic importance, with these methods, the accuracy of breeding value always remains questionable. Simulation and experimental results suggest that breeding values can be predicted with high accuracy by genomic selection for young animals without own performance. Genomic selection is a type of marker-assisted selection in which genetic markers covering the whole genome are used so that all quantitative trait loci are in linkage disequilibrium with at least one marker. The possibility to select …
