Farm Disease Crises In The United Kingdom: Lessons To Be Learned, Michael C. Appleby Jan 2003

Farm Disease Crises In The United Kingdom: Lessons To Be Learned, Michael C. Appleby

State of the Animals 2003

Over the last fifteen years, a diverse succession of disease-related crises has befallen farm animal and food industries in the United Kingdom. Some have involved animal health, with little risk to humans. Some have involved human health, with animals acting as a reservoir for infection but little affected themselves. Some, however— including the most alarming— have involved both animal and human health through zoonoses, diseases transmittable from animal to human. All of these crises are linked in the public mind and in many commentaries, and indeed there are issues that many of them share. The most common of these is …


Ehrlichia Chaffeensis: A Prototypical Emerging Pathogen, Christopher D. Paddock, James E. Childs Jan 2003

Ehrlichia Chaffeensis: A Prototypical Emerging Pathogen, Christopher D. Paddock, James E. Childs

Zoonotics and Wildlife Disease: Publications

In April 1986, a medical intern scanning the peripheral blood smear of a severely ill man with an unexplained illness observed peculiar intracytoplasmic inclusions in several of the patient’s monocytes. The patient described multiple tick bites sustained approximately 2 weeks earlier during a visit to a rural area in northern Arkansas, and a presumptive diagnosis of Rocky Mountain spotted fever had been made (104, 174). Clinicians and scientists subsequently identified these inclusions as clusters of bacteria belonging to the genus Ehrlichia, previously known in the United States solely as veterinary pathogens (174). Within the next 5 years, the organism …


Cd21-Positive Follicular Dendritic Cells A Possible Source Of PrpSc In Lymph Node Macrophages Of Scrapie-Infected Sheep, Lynn M. Herrmann, William P. Cheevers, William C. Davis, Donald P. Knowles, Katherine I. O'Rourke Jan 2003

Cd21-Positive Follicular Dendritic Cells A Possible Source Of PrpSc In Lymph Node Macrophages Of Scrapie-Infected Sheep, Lynn M. Herrmann, William P. Cheevers, William C. Davis, Donald P. Knowles, Katherine I. O'Rourke

Zoonotics and Wildlife Disease: Publications

Natural sheep scrapie is a prion disease characterized by the accumulation of PrPSc in brain and lymphoid tissues. Previous studies suggested that lymph node macrophages and follicular dendritic cells (FDC) accumulate PrPSc. In this study, lymph nodes were analyzed for the presence of PrPSc and macrophage or FDC markers using dual immunohistochemistry. A monoclonal antibody (mAb) to the C-terminus of PrP reacted with CD172a+ macrophages and CD21+ FDC processes in secondary follicles. However, a PrP N-terminus- specific mAb reacted with CD21+ FDC processes but not CD172a+ macrophages in secondary follicles. Neither the PrP N-terminus nor C-terminus-specific …

Immunohistochemical Detection And Distribution Of Prion Protein In A Goat With Natural Scrapie, Reginald A. Valdez, Matthew J. Rock, Anne K. Anderson, Katherine I. O'Rourke

Zoonotics and Wildlife Disease: Publications

Formalin-fixed, paraffin-embedded tissue sections from a 3-year-old female Angora goat suffering from clinical scrapie were immunostained after hydrated autoclaving using a monoclonal antibody (mAb, F99/ 97.6.1; IgG1) specific for a conserved epitope on the prion protein. Widespread and prominent deposition of the scrapie isoform of the prion protein (PrPSc) was observed in the brain, brainstem, spinal cord, retina, postganglionic neurons associated with parasympathetic ganglia of myenteric and submucosal plexuses, Peyer’s patches, peripheral lymph nodes, and pharyngeal and palatine tonsils. The goat was homozygous for PrP alleles encoding 5 octapeptide repeat sequences in the N-terminal region of the prion …

Zoonotics and Wildlife Disease: Publications

Conformational conversion of proteins in disease is likely to be accompanied by molecular surface exposure of previously sequestered amino-acid side chains. We found that induction of β-sheet structures in recombinant prion proteins is associated with increased solvent accessibility of tyrosine. Antibodies directed against the prion protein repeat motif, tyrosine-tyrosinearginine, recognize the pathological isoform of the prion protein but not the normal cellular isoform, as assessed by immunoprecipitation, plate capture immunoassay and flow cytometry. Antibody binding to the pathological epitope is saturable and specific, and can be created in vitro by partial denaturation of normal brain prion protein. Conformation-selective exposure of …

Zoonotics and Wildlife Disease: Publications

In a recently published article, Paramithiotis et al. describe antibodies specific for the prion Tyr-Tyr-Arg (YYR) repeat motif. These antibodies interact with the pathological isoform of the prion protein (PrPSC), but not with the normal cellular isoform (PrpC). Because of this restricted specificity, they suggest that YYR-specific antibodies could be useful for the diagnosis and treatment of prion diseases (Fig. O. The monoclonal antibodies, all of the IgM isotype, were produced by immunizing mice with a synthetic peptide (CYYRRYYRYY). When coupled to magnetic beads, these YYR-specific antibodies immunoprecipitate Prpsc much more efficiently than PrpC …


Monte Carlo Assessments Of Goodness-Of-Fit For Ecological Simulation Models, Lance A. Waller, David Smith, James E. Childs, Leslie A. Real Jan 2003

Monte Carlo Assessments Of Goodness-Of-Fit For Ecological Simulation Models, Lance A. Waller, David Smith, James E. Childs, Leslie A. Real

Zoonotics and Wildlife Disease: Publications

One often develops stochastic ecologic simulation models based on local interactions between individuals or groups and bases systemic conclusions on trends summarized over multiple data sets generated from the model. In many cases, such models generate data sets (“realizations”) each violating the usual assumptions associated with traditional statistical tests of goodness-of-fit, most notably that of independent observations. Monte Carlo hypothesis tests applied to multiple realizations from such models provide appropriate goodness-of-fit tests regardless of within-model peculiarities. The Monte Carlo tests address the question “Do the observed data appear consistent with the model?” in contrast to the usual question “Does the …

Zoonotics and Wildlife Disease: Publications

A monoclonal antibody dot-blot assay was used to evaluate detergent lysates of tonsil tissue from mule deer to detect PrPCWD, the marker for the cervid transmissible spongiform encephalopathy chronic wasting disease (CWD). Samples of formalin-fixed brain and tonsil tissues from mule deer were examined for PrPCWD using immunohistochemistry (IHC) with Mab F99/97.6.1, the gold standard for diagnosis of preclinical CWD. The contralateral tonsil from each of the 143 deer was prepared for confirmatory IHC and as a 10% (wt/vol) detergent lysate without purification or enrichment steps for monoclonal antibody dot-blot assay. PrPCWD was detected by dot-blot …


Genealogical Relationships Influence The Probability Of Infection With Bovine Tuberculosis And Microgeographic Genetic Structure In Free-Ranging White-Tailed Deer, Julie Anne Blanchong Jan 2003

Genealogical Relationships Influence The Probability Of Infection With Bovine Tuberculosis And Microgeographic Genetic Structure In Free-Ranging White-Tailed Deer, Julie Anne Blanchong

Michigan Bovine Tuberculosis Bibliography and Database

Zoonoses are of increasing importance to wildlife conservation and human health. It has become increasingly recognized that wildlife ecology plays a key role in disease transmission in wildlife populations. In domestic populations, contacts among individuals are controlled by humans and disease transmission is often density dependent. Unlike domestic animals, wildlife populations often have complex social systems in whch contacts among individuals are not solely density dependent, and can play an important role in the transmission and maintenance of disease.


A Priori Prediction Of Disease Invasion Dynamics In A Novel Environment, Colin A. Russell, David L. Smith, Lance A. Waller, James E. Childs, Leslie A. Real Jan 2003

A Priori Prediction Of Disease Invasion Dynamics In A Novel Environment, Colin A. Russell, David L. Smith, Lance A. Waller, James E. Childs, Leslie A. Real

Zoonotics and Wildlife Disease: Publications

Directly transmitted infectious diseases spread through wildlife populations as travelling waves away from the sites of original introduction. These waves often become distorted through their interaction with environmental and population heterogeneities and by long-distance translocation of infected individuals. Accurate a priori predictions of travelling waves of infection depend upon understanding and quantifying these distorting factors. We assess the effects of anisotropies arising from the orientation of rivers in relation to the direction of disease-front propagation and the damming effect of mountains on disease movement in natural populations. The model successfully predicts the local and large-scale prevaccination spread of raccoon rabies …

Bovine Tuberculosis In Michigan: Understanding Stakeholder Attitudes Toward The Disease And Eradication Efforts, Meegan Leah Dorn Jan 2003

Bovine Tuberculosis In Michigan: Understanding Stakeholder Attitudes Toward The Disease And Eradication Efforts, Meegan Leah Dorn

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis has been discovered at unprecedented levels in Michigan wildlife, especially white-tailed deer (Odocoileus virginianus). Human behaviors, particularly the use of bait and feed, have facilitated the spread of the disease into free-ranging white-tailed deer populations. Policies aimed at eradicating bovine tuberculosis in Michigan require public compliance and cooperation in order to be successful. Because of the human contribution to the spread of bovine tuberculosis in Michigan wildlife, and the social nature of subsequent bovine tuberculosis eradication policies, we conducted a survey of bovine TB issue stakeholder groups in northeast Michigan, including non-resident hunters, resident hunters, livestock …


Bovine Tuberculosis In Elk (Cervus Elaphus Manitobensis) Near Riding Mountain National Park, Manitoba, From 1992 To 2002 Jan 2003

Bovine Tuberculosis In Elk (Cervus Elaphus Manitobensis) Near Riding Mountain National Park, Manitoba, From 1992 To 2002

Michigan Bovine Tuberculosis Bibliography and Database

From 1991 to April 2003, outbreaks of bovine tuberculosis (TB caused by Mycobacterium bovis) have been found in 11 cattle herds surrounding Riding Mountain National Park (RMNP). Located in southwestern Manitoba, RMNP and the surrounding area are home to a free-ranging herd of 2500 to 4000 elk that have been implicated as being a wildlife reservoir of M. bovis infection. Indirect contact between cattle and elk that feed during the winter on the same large, round hay bales is presumed to be the most likely mode of transmission between the species (1).

Michigan Bovine Tuberculosis Bibliography and Database

Heads of hunter-harvested deer and elk were collected throughout South Dakota (USA) and within established chronic wasting disease (CWD) surveillance areas from 1997–2002 to determine infection with CWD and bovine tuberculosis (TB). We used immunohistochemistry to detect CWD-infected individuals among 1,672 deer and elk sampled via geographically targeted surveillance. A total of 537 elk (Cervus elaphus nelsoni), 813 white-tailed deer (Odocoileus virginianus), and 322 mule deer (O. hemionus) was sampled for CWD. Estimated overall prevalence and associated confidence intervals (95%) in white-tailed deer was 0.001% (0–0.007%). Similarly, estimated overall prevalence in elk and mule …

Spatial And Temporal Spread Of Bovine Tuberculosis In Wild White-Tailed Deer In Michigan, Graham J. Hickling, Stephen M. Schmitt, Daniel J. O'Brien

Michigan Bovine Tuberculosis Bibliography and Database

In 1975, a wild white-tailed deer infected with bovine tuberculosis was shot in the northeastern Lower Peninsula, Michigan. The shooting of a second infected deer in the same area in 1994 triggered ongoing disease surveillance in the region. By 2002, bovine tuberculosis had been confirmed in 12 Michigan counties: from 449 deer; two elk; 41 non-cervid wildlife; one captive cervid facility and 28 cattle herds. We analyzed geographic spread of disease since the surveillance began and investigated factors influencing the prevalence of disease within the infected area. These analyses reveal that 78 percent of tuberculous deer came from within a …

Mycobacterium infections occur in numerous wildlife species worldwide and this bacterial genus can also cause disease in humans and livestock. Two Mycobacterium species and one subspecies that infect wildlife are important from a wildlife damage management perspective. Mycobacterium avium, avian tuberculosis, is a ubiquitous and cosmopolitan disease of wild and domestic birds. Wild and domestic ruminants are host to M. avium paratuberculosis, also known as Johne’s disease. Finally, Mycobaterium bovis, bovine tuberculosis, is primarily associated with domestic and wild bovines and ungulates, but also infects many other species of mammals. Eradicating these diseases from wildlife populations is …

Isovolumetric Regulation In Mammal Cells: Role Of Taurine, B. Ordaz, R. Franco, National University Of Mexico Tuz Jan 2003

Isovolumetric Regulation In Mammal Cells: Role Of Taurine, B. Ordaz, R. Franco, National University Of Mexico Tuz

School of Veterinary and Biomedical Sciences: Faculty Publications

The ability to regulate cell volume is an ancient conserved trait present in essentially all species through evolution. The maintenance of a constant cell volume is a homeostatic imperative in animal cells. Changes in cell water content affecting the concentration of intracellular messenger molecules impair the complex signaling network, crucial for cell functioning and intercellular communication. Although the renal homeostatic mechanisms exert a precise control of extracellular fluid osmolarity, this is challenged in a variety of pathological situations. The intracellular volume constancy is continuously compromised by the generation of local and transient osmotic microgradients, associated with nutrients uptake, secretion, cytoskeleton …

The data were obtained from 22 Norduz male kids weaned at 3 months of age. The male kids were maintained in farm conditions. In male kids, least square means of testis diameter, testis length, scrotum circumference and scrotum length evaluated as testis measurements were 3.13 ± 0.08, 5.95 ± 0.14, 16.52 ± 0.39 and 10.60 ± 0.33 cm at 90 days, respectively, and 4.75 ± 0.08, 9.29 ± 0.14, 19.61 ± 0.40 and 12.38 …


Growth And Carcass Characteristics Of Three Fat-Tailed Pure Breeds Under Grazing With Concentrate Supplementation, Muhli̇s Maci̇t, Sirri Şahi̇n, Nuri̇ni̇sa Esenbuğa, Mevlüt Karaoğlu Jan 2003

Growth And Carcass Characteristics Of Three Fat-Tailed Pure Breeds Under Grazing With Concentrate Supplementation, Muhli̇s Maci̇t, Sirri Şahi̇n, Nuri̇ni̇sa Esenbuğa, Mevlüt Karaoğlu

Turkish Journal of Veterinary & Animal Sciences

Growth performance, carcass measurements and carcass characteristics of three fat-tailed Turkish breeds (Awassi = A, Morkaraman = M and Tushin = T) weaned at 2.5 months of age and subjected to semi-intensive feeding during a grazing period on pasture for 70 days were evaluated. At the end of the 70-day grazing period, M lambs showed the highest performance for daily weight gain and the amount of concentrate consumed per bodyweight gain in addition to grazing on pasture. The effects of the breed and sex of lambs on daily weight gain on pasture were significant (P < 0.05) and highly significant (P < 0.01), respectively. Male lambs were superior to female lambs with respect to daily weight gain on pasture. The slaughter traits, carcass measurements and carcass characteristics of 14 male lambs representing three fat-tailed breeds were compared at the end of the grazing period of the year in which they were born. After slaughter, carcasses were chilled at +4 °C for 24 h and measurements were taken on the intact cold carcasses. The carcasses were then dissected into wholesale cuts. The hot carcass weight and hindshank weight of M lambs were heavier than those of A and T lambs. M had a higher hot dressing percentage and larger M. longissimus dorsi (LD) area than those of A and T lambs. Most of the weights of wholesale cuts such as foreshank and breast, sirloin, leg, rib and hindshank were significantly (P < 0.05; P < 0.01) affected by sheep breed. It is recommended either that A, M or T male and female lambs weaned at 2.5 months of age in eastern Turkey should be fed with 450 g concentrate per head per day on pasture for 3 to 3.5 months of grazing season, or lambs should be supplemented with more than 450 g concentrate feed on pasture because native fat-tailed Turkish breeds supplemented with 450 g concentrate on pasture did not give carcasses with an adequate commercial weight at the end of a 70-day fattening period.

Morphological And Biophysical Properties Of The Cells Involving The Reflexive Orienting Responses Of The Eye, Head And Body, Ramazan Bal

Turkish Journal of Veterinary & Animal Sciences

The intrinsic membrane properties of the neurons in the cortices of the inferior colliculus were studied in 300-µm transversal slices. The membrane properties, including the sub- and superthreshold, of the neurons were determined by intracellular stimulations with current injections. Of 49 intracellularly recorded neurons, 21 were successfully stained with intracellular biocytin injection. Morphologically all of the 21 neurons were identified as multipolar. Physiologically three firing patterns (onset, regular and adapting) were identified on the basis of response patterns to depolarizing current injections. Onset neurons had a non-linear, and regular and adapting neurons had linear current-voltage relationships. In conclusion, with the …

This study was carried out to determine Eimeria infection in goats in nine different districts in Van province in Turkey. Faecal samples (approximately 3-5 g) were obtained from the rectums of 242 goats. The samples were examined by Sheather's sugar flotation technique and determined microscopically for the presence of oocysts. Eimeria species were identified following sporulation of faeces in a thin layer of 2.5% potassium dichromate for one or two weeks at 25 ºC. All samples were later examined for identification of Eimeria species. Nine different species of Eimeria oocysts were detected in 73.6% of the goats. These species were …


Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu Jan 2003

Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu

Turkish Journal of Veterinary & Animal Sciences

Non-motile, Gram-positive and catalase-negative anaerobic Leuconostoc sp. were found to be involved in the spoilage of vacuum-packaged refrigerated sucuk samples. The spoilage was associated with an accumulation of large quantities of foul-smelling gas and purge in the bag and loss of colour and texture in the meat. Many of these isolates produce bacteriocins, to which the predominant Gram-positive bacteria normally found in these products are sensitive. As the leuconostocs grew at low temperatures and produced bacteriocins, they inhibited the growth of associated sensitive bacteria. Attempts to inoculate purge from spoiled samples into fresh meat, vacuum packaging and refrigeration storage facilitated …

The Effect Of Age, Sex, Housing System And Pregnancy On Some Blood Parameters Of Tuj Sheep, Ömer Bozdoğan, Meti̇n Çenesi̇z, Mehmet Kaya, Nadi̇de Nabi̇l Kami̇loğlu Jan 2003

The Effect Of Age, Sex, Housing System And Pregnancy On Some Blood Parameters Of Tuj Sheep, Ömer Bozdoğan, Meti̇n Çenesi̇z, Mehmet Kaya, Nadi̇de Nabi̇l Kami̇loğlu

Turkish Journal of Veterinary & Animal Sciences

In this study some blood parameters and the effects of age, sex, housing system and pregnancy of Tuj sheep that have been bred in the Kars region of Turkey were researched and compared. The various blood parameters including the amount of haemoglobin, haematocrit value, erythrocyte and leukocyte count, and the differential percentage of white blood cells were determined from blood taken intravenously. The haemoglobin and erythrocyte values were found to be significantly (p < 0.05) higher in 5-7-month-old Tuj sheep grazing in an open field than in 2-3-month-old male Tuj sheep feeding in a closed system. The erythrocyte count was found to be higher in 2-3-month-old female Tuj sheep in comparison to males. The haemoglobin, leukocyte and haematocrit values were also higher in this group of animals, though this was not statistically significant. The erythrocyte, leukocyte, haemoglobin, haematocrit values and differential percentage of white blood cells were not different in 5-7-month-old male and female Tuj sheep grazing in an open area. The erythrocyte number decreased after parturition in respect to the oestrus and pregnancy period. This decrease was statistically significant. The erythrocyte values were 10.2 x 10^6 /mm^3 before oestrus, 9.5 x 10^6 /mm3 during pregnancy and 8.2 x 10^6 /mm^3 after parturition. The haemoglobin value decreased significantly (p < 0.05) during pregnancy. The leukocyte number was found to be less during pregnancy in comparison to other periods; it was 7.7 ± 1.9 x 10^3 /mm^3 during pregnancy, 9.3 ± 1.9 x 10^3 /mm^3 before oestrus, and 9.7 ± 2.5 x 10^3 /mm^3 after parturation. The lymphocyte percentage increased significantly (p < 0.05) during the pregnancy period.
