Aspergillosis And Gastric Impaction In An Ostrich, Azi̇z Arda Sancak, Jale Paracikoğlu Jan 2005

Aspergillosis And Gastric Impaction In An Ostrich, Azi̇z Arda Sancak, Jale Paracikoğlu

Turkish Journal of Veterinary & Animal Sciences

It is inevitable to encounter many diseases of ostriches in Turkey as a consequence of the rapid expansion of ostrich farming and flocks in this country. Aspergillus fumigatus was isolated from the lungs and air sacs of a 3-month-old, male, blue-neck ostrich. In postmortem examination, the ingestion of a large amount of gravel was noted. The accumulated gravel had led to an occlusion of the passage between the proventriculus and gizzard. This work appears to be the first report of aspergillosis and gastric impaction developing together and leading to death in an ostrich.

Genetics And Functions Of The Sars Coronavirus Spike Protein, Chad Michael Petit Jan 2005

Genetics And Functions Of The Sars Coronavirus Spike Protein, Chad Michael Petit

LSU Doctoral Dissertations

The SARS-Coronavirus (SARS-CoV) is the etiological agent of the severe acute respiratory syndrome (SARS). The SARS-CoV spike (S) glycoprotein mediates membrane fusion events during virus entry and virus-induced cell-to-cell fusion. Investigations, described herein, have focused on the genetic manipulation of the SARS-CoV S glycoprotein in order to delineate functional domains within the protein. This was accomplished by incorporating single point mutations, cluster-to-lysine and cluster-to-alanine mutations, as well as carboxyl terminal truncations into the protein and investigating these mutants in transient expression experiments. Mutagenesis of either the coiled-coil domain of the S glycoprotein amino terminal heptad repeat, the predicted fusion peptide, …

The Role Of Urease In The Pathogenesis Of Edwardsiella Ictaluri, Natha Joy Booth Jan 2005

The Role Of Urease In The Pathogenesis Of Edwardsiella Ictaluri, Natha Joy Booth

LSU Doctoral Dissertations

An Edwardsiella ictaluri strain with disruption of ureG was identified through the use of signature tagged insertion mutagenesis as being attenuated for virulence in the channel catfish host. Sequencing of the flanking regions surrounding the insert showed that the gene was part of a urease gene complex that included ureE, ureF, ureG, ureD, ureI, and an ammonium transporter homologue. The ureG gene encodes a GTP-binding accessory protein which is thought to function in energy-dependent urease assembly. The ureG mutant strain was found to be attenuated for mortality, persistence, and for the ability to establish infection in a competition challenge during …

Cetacean Brain Evolution: Multiplication Generates Complexity, Lori Marino Dec 2004

Cetacean Brain Evolution: Multiplication Generates Complexity, Lori Marino

Anatomy Collection

Over the past 55-60 million years cetacean (dolphin, whale, and porpoise) brains have become hyperexpanded so that modern cetacean encephalization levels are second only to modern humans. At the same time, brain expansion proceeded along very different lines than in other large-brained mammals so that substantial differences between modern cetacean brains and other mammalian brains exist at every level of brain organization. Perhaps the most profound difference between cetacean and other mammalian brains is in the architecture of the neocortex. Cetaceans possess a unique underlying neocortical organizational scheme that is particularly intriguing in light of the fact that cetaceans exhibit …

The Characterization Of Clays And Cetylpyridiniumexchanged Clays For Their Ability To Adsorb Zearalenone, Komkrich Pimpukdee, Bundit Tengjaroenkul, Prapansak Chaveerach, Benjamas Mhosatanun Dec 2004

The Characterization Of Clays And Cetylpyridiniumexchanged Clays For Their Ability To Adsorb Zearalenone, Komkrich Pimpukdee, Bundit Tengjaroenkul, Prapansak Chaveerach, Benjamas Mhosatanun

The Thai Journal of Veterinary Medicine

The adsorption of zearalenone (ZEN) onto Ca-montmorillonite (STx-1), Na-montmorillonite (SWy-2), acid-activated montmorillonite (AAM), clinoptilolite and cetylpyridinium (CP) exchanged clays was studied. The results indicated that CP-exchanged clays were more effective than unmodified base clays in adsorbing ZEN, i. e. STx-1 (7.4±2.3 mg/g) < clinoptilolite (7.6±1.1 mg/g) < AAM (10.0±0.0 mg/g) < SWy-2 (11.9±0.4 mg/g), whereas the extent of ZEN adsorption into modified clay products did not follow the order seen in the based clays. The adsorption efficiency of CP-exchanged clays is in the order of CP*STx-1 (56.9±1.1 mg/g) = CP*AAM (56.9±1.8 mg/g) > CP*SWy-2 (47.9±2.6 mg/g) > CP*clinoptilolite (15.5±1.1 mg/g). Three CP-exchanged clays were further characterized by isotherm studies. The results indicated that the isotherm shapes of CP*exchanged clays exhibited a S-shape. The isotherm plot is concave up to the inflection point and then plateaus, which suggests multiple, specific binding sites and saturation at each site. It is important to rigorously test …

Multidrug Efflux Systems (Mes): A Mechanism Of Resistance To Multidrug In Bacteria, Rungtip Chuanchuen, Herbert P. Schweizer Dec 2004

Multidrug Efflux Systems (Mes): A Mechanism Of Resistance To Multidrug In Bacteria, Rungtip Chuanchuen, Herbert P. Schweizer

The Thai Journal of Veterinary Medicine

Bacterial antibiotic resistance is a growing problem with a global dimension. While the mechanisms of resistance vary from agent to agent, most of them are agent specific, providing resistance to a single or a class of anitimicrobials. Multidrug efflux systems have currently emerged as a predominant cause of antimicrobial resistance across a broad spectrum of structurally - unrelated antimicrobials. Efflux-mediated resistance is promoted by the exclusion of agents from the systems, resulting in reduced intracellular concentration of drugs. MES occur in many Gram-positive and Gram-negative bacteria, including medically important pathogens, therefore they are of significant concern. Expression of the systems …

The Expression Of C-Erbb2 Oncogene Protein As A Prognostic Factor In Feline Mammary Tumors, Mataya Taweechart, On-Uma Sirayayon, Grisnarong Wongbandue, Supradit Wangnaitham, Achariya Sailasuta, Sudson Sirividhayapong, Anudep Rungsipipat Dec 2004

The Expression Of C-Erbb2 Oncogene Protein As A Prognostic Factor In Feline Mammary Tumors, Mataya Taweechart, On-Uma Sirayayon, Grisnarong Wongbandue, Supradit Wangnaitham, Achariya Sailasuta, Sudson Sirividhayapong, Anudep Rungsipipat

The Thai Journal of Veterinary Medicine

The study looked at the relationship between the expression of c-erbB2 oncogene protein, histological types, PCNA and AgNORs indices, in feline mammary tumors. Sixty, surgically resected, mammary tumors from cats were collected and histological processed. The expression of c-erbB2 oncogene protein was detected by immunohistochemistry and was seen in benign hyperplasia, adenosis and malignant groups. The c-erbB2 oncogene protein expression in malignant, feline mammary tumors was 41.67% (25/60) which could be divided into simple tubular ACC, 25% (6/24), simple papillary ACC, 78.6% (11/14), solid carcinoma, 26.7% (4/15) and cribiform carcinoma, 57.14% (4/7). There were statistically significantly differences (p<0.05) in the expression of c-erbB2 oncogene protein between simple tubular ACC, compared with simple papillary ACC and solid carcinomas. The expression of c-erbB2 oncogene protein in specimens, classified by histological malignancy grades revealed, grade I, 42.11% and grade II, 41.46% but there was no statistically significant difference between them. An evaluation of a proliferative marker shown by a mean (±SD) of PCNA, was 34.63±23.87 and the mean (±SD) of AgNORs was 1.23±0.18. There was no significant difference between the PCNA and AgNORs index of both the histological types and the histological malignancy grades. However, a statistical difference of mean PCNA and AgNORs indices was noted in both c-erbB2 positive and c-erbB2 negative groups. The mean PCNA indices and AgNORs indices in c-erbB2 positive samples were 26.52±18.68 and 1.12±0.27 respectively, while the c-erbB2 negative ones were 39.43±26.24 and 1.28±0.19 respectively. In conclusion, c-erbB2 oncogene protein expression is considered to be an effective prognostic factor for adenocarcinoma subtypes of feline mammary tumors as it is in human and canine cases. However, integration of all the parameters (c-erbB2 oncogene protein, PCNA index, AgNORs index, histological types and clinical data) may achieve a more precise prognosis in feline, mammary tumor cases.
