Listeria Monocytogenes, Yersinia Enterocolitica And Salmonella Enteritidis In Quail Eggs, Özlem Turgay

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the presence of Listeria monocytogenes, Yersinia enterocolitica and Salmonella enteritidis in 123 liquid whole quail eggs. The method suggested by USDA-FSIS was used for the isolation and identification of L. monocytogenes. S. enteritidis was identified and sero-grouped by co-agglutination test and slide agglutination test. Y. enterocolitica was isolated in Trypticase-Soy Broth, with bile-oxalate-sorbose medium for enrichment. Both enrichment cultures were plated on Yersinia Selective Agar Base containing cefsulodin, irgasan and novobiocin (CIN Agar). No Yersinia was detected among the natural flora of the quail eggs. Seven (5.69%) of 123 whole quail eggs …

Determination Of Microbial Gas Production, Fermentation Kinetics And Digestibility Of Alternative Crop Silages, İsmai̇l Akyol, Emi̇n Özköse, Mehmet Sai̇t Eki̇nci̇ Jan 2004

Determination Of Microbial Gas Production, Fermentation Kinetics And Digestibility Of Alternative Crop Silages, İsmai̇l Akyol, Emi̇n Özköse, Mehmet Sai̇t Eki̇nci̇

Turkish Journal of Veterinary & Animal Sciences

Microbial gas production (MGP), fermentation kinetics and DM loss of crop silages made from 7 different plant families (barley/pea, clover, grass, kale, lotus, lucerne, sainfoin) and 10 different refusals were determined. The pressure transducer technique (PTT) was used to measure the microbial gas production of fresh and ground silages and refusal samples at regular intervals throughout the 120 h incubation. The MGP of fresh and ground silages were similar (r^2 = 0.90). The maximum gas production was obtained from kale for ground and fresh silages whilst grass silage yielded the maximum gas pool for refusals. No differences were found between …

Is The Fluid Milk Subsector Competitive In Turkey?, Seli̇m Adem Hatirli Jan 2004

Is The Fluid Milk Subsector Competitive In Turkey?, Seli̇m Adem Hatirli

Turkish Journal of Veterinary & Animal Sciences

The significant increase in the concentration ratio in Turkey’s fluid milk market has heightened concern about the exercise of market power. During 1980-98, the 4-firm concentration ratio and Herfindahl index increased by 11% and 33%, respectively. In this study, we estimated the degree of imperfection in the fluid milk market at retail level using the New Empirical Industrial Organization approach during the period 1980-98. For this purpose, the demand equation and first-order-profit maximization condition, which allow the degree of market power to be determined, were estimated. Using 2-stage-least-square estimation, market power was found to be 0.11. This parameter shows that …

Isolation And Characterization Of Mycobacteria From Striped Bass Morone Saxatilis From The Chesapeake Bay, Martha W. Rhodes, Howard Kator, Ilsa Kaattari, David Gauthier, Wolfgang Vogelbein, Christopher A. Ottinger

Biological Sciences Faculty Publications

Mycobacteriosis in striped bass Morone saxatilisof Chesapeake Bay, USA, was first diagnosed in 1997 based on the presence of granulomatous inflammation and acid-fast bacteria in skin and spleen. To confirm histopathology, bacteriological detection and identification of mycobacteria were begun using splenic tissue from fish with and without skin ulcerations. On the basis of initial studies using a variety of selective and nonselective media, decontamination, homogenization and incubation conditions, a simple and quantitative recovery method using aseptic necropsy of splenic tissue was developed. Optimal recovery was obtained by spread-plating homogenates on Middlebrook 7H10 agar with incubation for 3 mo at …

Evaluation Of Rough Brucella Strains As Vaccines For Brucellosis And Pseudorabies In Swine, Lorraine Harrow Molin Jan 2004

Evaluation Of Rough Brucella Strains As Vaccines For Brucellosis And Pseudorabies In Swine, Lorraine Harrow Molin

LSU Master's Theses

Brucellosis and pseudorabies lead to abortion in pregnant sows and are perpetuated by feral swine reservoirs. A multivalent oral vaccine for these diseases would improve vaccination and eradication programs worldwide. Previous studies have shown that the rough attenuated Brucella strains RB51 and VTRS1, when administered subcutaneously to swine, stimulate host immune responses, transiently colonize tissues, and provide partial protection against virulent B. suis infection in pregnant sows. A plasmid encoding for the pseudorabies virus glycoprotein D (PRV gD) has also been added to these strains as part of this project. This study evaluates the use of these strains as oral …

Turkish Journal of Veterinary & Animal Sciences

Because of the interaction between nitric oxide (NO) and the superoxide anion radical, the effect of ischemia-reperfusion on intestinal contractility regulated by the nitrergic system was investigated in the present study. The study was performed on 3 groups of rabbits: group 1, ischemia; group 2, ischemia and 1 h of reperfusion; group 3, ischemia and 24 h of reperfusion. Tissue samples were obtained from ischemic, ischemia-reperfused and adjacent uninjured intestines as study and control samples. The effects of atropine, tetrodotoxin, L-NAME and L-arginine on the intestinal response to electrical field stimulation (EFS) were investigated. Guanethidine was used to minimize adrenergic …

Isolation And Characterization Of Carbonic Anhydrase From Ostertagia Ostertagi, Andrew Allan Derosa Jan 2004

Isolation And Characterization Of Carbonic Anhydrase From Ostertagia Ostertagi, Andrew Allan Derosa

LSU Doctoral Dissertations

The first event in the infection process of Ostertagia ostertagi in cattle is the process of exsheathment. Before trichostrongylid nematodes can transition from a free-living infective stage larva (L3) on pasture to a parasitic existence within the ruminant host, it must first undergo exsheathment. Exsheathment is the process whereby the L2 cuticle retained from the previous molt is cast from the L3. Exsheathment enables the developmental transition from a free-living stage on pasture to a parasitic existence in the bovine host. For those species with a predilection site in the abomasum, such as O. ostertagi, …

Estimation Of The Effect Of Misclassifications On Diagnostic Test Performance In Two Persistent Bovine Viral Infections, Kimberly Orr Jan 2004

Estimation Of The Effect Of Misclassifications On Diagnostic Test Performance In Two Persistent Bovine Viral Infections, Kimberly Orr

LSU Doctoral Dissertations

Validation of diagnostic assay performance is hampered where no gold standard exists. Bayesian estimates of the sensitivity and specificity were applied to studies of two persistent bovine infections: bovine immunodeficiency virus (BIV), and bovine viral diarrhea virus (BVDV). BVDV pathogenesis is well described. Losses of $20 million in 1992 alone led the Danish government to mandate eradication. Two enzyme-linked immunosorbent assay (ELISA) tests were developed; one antibody-based to detect exposure, one antigen-based to detect persistent infection. Bayesian estimates of the sensitivity and specificity were 96.6% and 99.2%, and 98.2% and 99.8% for the antibody and antigen ELISA, respectively. Maximum Likelihood …

Developing Embryo Technologies For The Eland Antelope (Taurotragus Oryx), Gemechu G. Wirtu

LSU Doctoral Dissertations

Assisted reproductive technologies developed in domestic cattle serve as a starting point in similar studies on nondomestic bovids. The common eland is a useful model species for studies on rare tragelaphine antelopes. In Chapter 3 of the present study, effects of components/attributes of protein-free embryo culture media on the in vitro development of in vitro-derived bovine embryos were evaluated. A 2 x 2 factorial study comparing effects of groups of amino acids (20aa or 11aa) in two base media (modified KSOM or BM-3) demonstrated that amino acids and base medium affected embryonic development. A subsequent 7 x 2 factorial experiment …
