Risk Of Disease From Wildlife Reservoirs: Badgers, Cattle, And Bovine Tuberculosis, M. Scantlebury, M. R. Hutchings, D. J. Allcroft, S. Harris Jan 2004

Risk Of Disease From Wildlife Reservoirs: Badgers, Cattle, And Bovine Tuberculosis, M. Scantlebury, M. R. Hutchings, D. J. Allcroft, S. Harris

Michigan Bovine Tuberculosis Bibliography and Database

Livestock face complex foraging options associated with optimizing nutrient intake while being able to avoid areas posing risk of parasites or disease. Areas of tall nutrient-rich swards around fecal deposits may be attractive for grazing, but might incur fitness costs from parasites. We use the example of dairy cattle and the risks of tuberculosis transmission posed to them by pastures contaminated with badger excreta to examine this trade-off. A risk may be posed either by aerosolized inhalation through investigation or by ingestion via grazing contaminated swards. We quantified the levels of investigation and grazing of 150 dairy cows at badger …

Phosphorylation Of Vesicular Stomatitis Virus Phosphoprotein P Is Indispensable For Virus Growth†, Subash C. Das, Asit K. Pattnaik Jan 2004

Phosphorylation Of Vesicular Stomatitis Virus Phosphoprotein P Is Indispensable For Virus Growth†, Subash C. Das, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The phosphoprotein (P) of vesicular stomatitis virus (VSV) is an essential subunit of the viral RNAdependent RNA polymerase (RdRp) complex. It is phosphorylated at two different domains. Using defective interfering (DI) RNA or minigenomic RNA templates, we previously demonstrated that phosphorylation within the amino-terminal domain I is essential for transcription, whereas phosphorylation within the carboxyterminal domain II is necessary for replication. For the present study, we examined the role of the phosphorylation of residues in these domains in the life cycle of VSV. Various mutant P coding sequences were inserted into a full-length cDNA clone of VSV, and the virus …

Maxwell H. Gluck Equine Research Center Faculty Publications

Isoxsuprine is used to treat navicular disease and other lower-limb problems in the horse. Isoxsuprine is regulated as a class 4 compound by the Association of Racing Commissioners, International (ARCI) and, thus, requires regulatory monitoring. A gas chromatography-mass spectrometry method utilizing electron impact ionization was developed and validated for the quantitation of isoxsuprine in equine plasma or equine urine. The method utilized robotic solid-phase extraction and tri-methyl silyl ether products of derivatization. Products were bis-trimethylsilyl (TMS) isoxsuprine and tris-TMS ritodrine, which released intense quantifier ions m/z 178 for isoxsuprine and m/z 236 for ritodrine that were products of C-C cleavage. …

The Mare Reproductive Loss Syndrome And The Eastern Tent Caterpillar Ii: A Toxicokinetic/Clinical Evaluation And A Proposed Pathogenesis: Septic Penetrating Setae, Thomas Tobin, J. Daniel Harkins, John Ford Roberts, Patricia W. Vanmeter, Tara A. Fuller Jan 2004

The Mare Reproductive Loss Syndrome And The Eastern Tent Caterpillar Ii: A Toxicokinetic/Clinical Evaluation And A Proposed Pathogenesis: Septic Penetrating Setae, Thomas Tobin, J. Daniel Harkins, John Ford Roberts, Patricia W. Vanmeter, Tara A. Fuller

Maxwell H. Gluck Equine Research Center Faculty Publications

Reviewing the mare reproductive loss syndrome (MRLS), it is proposed that the fundamental mechanism of this syndrome, which includes early fetal loss, late fetal loss, uveitis, pericarditis, and encephalitis, is tissue penetration by septic barbed setal fragments (septic penetrating setae) from Eastern tent caterpillars (Malacosoma americanum). Once ingested, these barbed setal fragments migrate through moving tissues, followed by rapid hematogenous spread of bacteria, bacterial emboli, and/or septic fragments of setae (septic penetrating setal emboli), collectively referred to as septic materials. Pathogenic bacteria, therefore, enter the horse as hitchhikers on or in the caterpillar setal fragments, and MRLS is caused by …

Endometrial Polyps And Adenoma In A Cat With Hydrometra: Case Report, Hasan Ceyhun Macun, Ni̇hat Özyurtlu Jan 2004

Endometrial Polyps And Adenoma In A Cat With Hydrometra: Case Report, Hasan Ceyhun Macun, Ni̇hat Özyurtlu

Turkish Journal of Veterinary & Animal Sciences

A 1-year-old cat with a suspected abortion was brought to the clinic of the Department of Obstetrics and Gynaecology, Faculty of Veterinary Medicine, Ankara University. The cat was examined because of a reoccurrence of a bloody vaginal discharge. Failure to detect a foetus by ultrasonography and the presence of an anechoic zone in the uterus revealed that there had not an abortion. Since the anechoic zone was large, it was thought that a pharmacological approach would not be successful. Despite the vaginal discharge, the physical condition of the patient was suitable for surgery. Therefore, we decided to perform an ovariohysterectomy. …

Regional Impacts Of Alternative Price Policies For Turkey's Dairy Sector, Fahri̇ Yavuz, Si̇bel Tan, Carl R. Zulauf Jan 2004

Regional Impacts Of Alternative Price Policies For Turkey's Dairy Sector, Fahri̇ Yavuz, Si̇bel Tan, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

Regional impacts of agricultural policies have emerged as a key concern in Turkey for both domestic reasons and because of Turkey's desire to join the European Union. This study uses a spatial equilibrium model to analyze the regional impacts of 2 alternative dairy support policies that are currently being considered: a price premium policy and a target price/deficiency payment policy. Both policies are found to exacerbate the post-1980 trend toward a greater share of milk produced in the more prosperous western regions of Turkey. Regional disparity in milk production increases more under the target price policy than under the price …

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven Jan 2004

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven

Turkish Journal of Veterinary & Animal Sciences

We aimed to improve the selectivity of lauryl tryptose (LST) broth and HC (hemorrhagic colitis Escherichia coli strains) agar for the detection of E. coli O157:H7 in frozen ground beef samples. The selectivity of LST broth was superior to that of LST containing novobiocin (20 mg/l) (LST + n), but LST containing novobiocin, cefixime (0.05 mg/l) and tellurite (2.5 mg/l) (LST + nct) was found to be unsuitable as an enrichment medium. The sorbitol positive strains were significantly more resistant to novobiocin than were the sorbitol negative strains (P < 0.05). As a result, the enrichment of ground beef samples in a selective broth without antibiotics such as LST, and then spread plating a subsequent amount from this original enrichment culture and the first three 10-fold serial dilutions onto a rhamnose and sorbitol based selective medium such as cefixime-tellurite HC medium (CTR-HC) was found to be recommendable as a routine cultural method. Transferring the metallic sheen property of eosin methylene blue (EMB) agar to CTR-HC agar can represent an alternative to the available media, and this will shorten the analysis time by 1 day. Use of salicine or 4-methylumbelliferyl-b-D glucuronide appears unnecessary in routine cultural techniques.

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf Jan 2004

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

A common concern with official estimates of red meat production in Turkey is that they underestimate the level of production. One of the frequently cited reasons is that unregulated slaughter is undercounted. This study uses an estimation method based on the biology of red meat production to examine the potential impact of this undercounting. The production estimates obtained for 1991-1998 using this biological-based method exceed the numbers estimated by official organizations, but fall within the range of estimates obtained from other proposed approaches to estimating red meat production.

This study aimed to investigate whether the preovulatory LH surge mechanism is involved in sheep-to-sheep interaction for oestrous synchronisation. For that purpose, anoestrous ewes were inserted with intravaginal progestagen sponges for 13 days to induce ovulation. Upon sponge withdrawal, they were introduced either to 4 rams (n = 6, ram group), or to 4 ewes which were in follicular period (n = 6, follicular group), or 4 ewes which were in the luteal period (n = 6, luteal group) or else they were kept alone (n = 6, control group). The ewes were weighed and their body conditions were scored …

Inhibitory effects of some antibiotics on glucose 6-phosphate dehydrogenase from the erythrocytes of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) were investigated. For this purpose, initially erythrocyte glucose 6-phosphate dehydrogenase was purified 1271.19-fold in a yield of 70.40% by using ammonium sulfate precipitation and 2',5'-ADP Sepharose 4B affinity gel. A constant temperature (+4 ºC) was maintained during the purification process. Enzyme activity was determined with the Beutler method by using a spectrophotometer at 340 nm. This method was utilized for all kinetic studies. Thiamphenicol, amikacin, gentamicin, and netilmicin were used as antibiotics. All the antibiotics exhibited inhibitory effects on the enzyme. …

Mycobacterium bovis infection in wildlife and feral species is a potential source of infection for livestock and a threat to protected and endangered species. The aim of this study was to identify Spanish wild animal species infected with M. bovis through bacteriological culture and spacer oligonucleotide typing (spoligotyping) of isolates for epidemiological purposes. This study included samples from red deer (Cervus elaphus), fallow deer (Dama dama), wild boar (Sus scrofa), Iberian lynx (Lynx pardina), hare (Lepus europaeus), and cattle (Bos taurus). They were collected in several geographical areas …
