The Sero-prevalence of Salmonella spp. in Finishing Swine in Iowa

This study represents the first attempt to classify Iowa production sites for Salmonella spp. sero-prevalence. The data suggest that the Iowa herds are similar in their distribution with respect to sero-prevalence of salmonella as Danish herds. Ignoring herd size, 91.2 of surveyed herds were negative or level 1, 8.2 % were level 2 herds, and 1.6 % level 3. These results are similar to previous Danish studies (Alban et al., 2002, Mousing et al., 1997). The current data suggests that larger herds tend to have a higher sero-prevalence than smaller units; however, formal analysis has yet to be conducted to determine the direct association between herd size and salmonella sero-prevalence. Studies by Carstensen et al. (1998) suggested that herd size was statistically associated, albeit weakly, with Salmonella sero-prevalence, but the authors concluded the relationship was probably not biologically significant

Determination of Toxoplasma gondii Antibody Prevalence in Midwest Market Swine

Pork has been identified as one of the food source(s) for human exposure to Toxoplasma gondii. This project was designed to determine the current prevalence of Toxoplasma gondii antibodies in the Midwestern USA market swine population. Test samples were selected, using random numbers generated from the Excel database, from approximately 2,500 daily meat juice samples submitted for Aujeszky’s Disease from eight Iowa abattoirs. Producer identification and lot size were recorded for each lot. Two hundred fifty samples were selected for 12 consecutive weeks – total of 15,014 samples. The presence of antibodies was determined using ELISA test kits by Safepath Laboratories. The prevalence for all samples was 0.75 % with a higher prevalence found in lots of 20 - 40 compared to 150 - 190 head. Additional on-farm evaluations of exposure risk factors are required to determine an association between sero-prevalence and lot size and to develop suitable prevention strategies

Optimal state-space control of a gas turbine engine

Introduction and Model Description The development of a state-space fuel control on a singleshaft, simple cycle gas turbine engine is the subject of this paper. A model of this simple engine with analog fuel control was available. The load transients of this model have been compared with actual load transients and found to be accurate. This verified model becomes a tool for developing multimode state-space controllers for more complicated engines. For example, a possible future high-efficiency engine for powering naval ships is an intercooled, regenerated (ICR) gas turbine engine [1], The control for this future engine will involve monitoring several outputs and will have three to five inputs. The number of inputs will vary with the mode of operation. A computer in the control loop will allow for many sophisticated modes and, also, allow for improvements in control strategy after initial development and even after installation. Fuel controls for future engines will be developed and verified with this simpler engine model as a tool. A simple cycle single-shaft gas turbine engine was modeled using ACSL (Advanced Continuous Simulation Language) Mass balance: DW3 is change in mass in V3 per unit time WA2 is mass rate into V3 where: Contributed by the International Gas Turbine Institute and presented at the 36th International Gas Turbine and Aeroengine Congress and Exposition, Orlando, Florida, June 3-6, 1991.

Differential expression of sheep beta-defensin-1 and -2 and interleukin 8 during acute Mannheimia haemolytica pneumonia

Beta-defensins are antimicrobial peptides produced by several cell types, including respiratory epithelia and leukocytes. Expression of some beta-defensins is increased by bacterial-induced inflammatory responses whereas expression of other beta-defensins is constitutive. Two beta-defensins are expressed in lungs of sheep (sheep beta-defensin-1 and -2; SBD-1/-2) and expression of SBD-1 is increased during parainfluenza virus type 3 (PI-3) infection. The effect of Mannheimia haemolytica, a Gram-negative bacteria known to induce expression of bovine beta-defensins and NF-kappa B in lung, has not been determined for SBD-1/-2. In this study, different concentrations of M. haemolytica were inoculated into pulmonary bronchi of lambs. SBD-1 and SBD-2 mRNA levels detected by real time reverse transcriptase polymerase chain reaction in lung homogenates did not increase. In fact, SBD-1 mRNA levels were significantly decreased with the highest administered inoculum concentration (109). In contrast, mRNA levels of interleukin-8 (IL-8) were significantly increased over controls and progressively increased with M. haemolytica concentrations. Co-inoculation of M. haemolytica with xylitol, an osmotic agent, did not alter mRNA levels of SBD-1, SBD-2 or IL-8. SBD-1 mRNA expression was detected in lung epithelia, but not in leukocytes. This study suggests that SDB-1 expression occurs in epithelia and decreases during severe bacterial pneumonia, which is in contrast to the increase that occurs with PI-3 infection

Lingual haemangiosarcoma in a crossbred dog

An eight-year-old, male neutered, crossbred dog was presented for investigation of a lingual mass of four months duration. Oral examination revealed a 7 cm × 5 cm soft, fluctuant mass at the caudal aspect of the tongue. Ultrasound examination of the mass demonstrated mixed echogenicity, with cavitations containing hypoechoic and anechoic regions. Lingual haemangiosarcoma was diagnosed on histopathological examination of multiple biopsy samples, with confirmation of the vascular endothelial origin of tumour cells by positive immunolabelling for factor VIII-related antigen

Physiological values of some blood indicators in selected dwarf rabbit breeds

[EN] The aim of the present study was to evaluate the effect of breed on haematological and biochemical indicators in 3 dwarf rabbit breeds. In the experiment, 30 sexually intact dwarf rabbit females aged 6 mo were used. With the sole exception of white blood cells and haematocrit value, breed had the most significant effect on the majority of haematological indicators monitored. The red blood cell count was higher in the Dwarf Lop compared to the Netherland Dwarf (+1.91×1012 cells/L; P<0.05) and also the Teddy Dwarf (+1.32×1012 cells/L; P<0.05). For haemoglobin concentration, a higher value was found in the Netherland Dwarf than in the Teddy Dwarf (+39.29 g/L; P<0.05) and the Dwarf Lop (+26.36 g/L; P<0.05). For erythrocytic indicators, the highest values of mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were found in the Netherland Dwarf. The breed had a significant effect on the urea and potassium values. A higher value of urea was recorded in the Dwarf Lop compared to the Teddy Dwarf (+1.56 mmol/L; P<0.05). For potassium, a higher value was found in the Netherland Dwarf compared to the Teddy Dwarf (+0.85 mmol/L; P<0.05). In addition, a significantly positive correlation (P<0.05) was found between the live weight of dwarf females and values of haematocrit (0.49), albumin (0.54), alanine aminotransferase (0.51), and aspartate aminotransferase (0.41), while a significantly negative correlation (P<0.05) was found between their live weight and values of triacylglycerols (–0.44), alkaline phosphatase (–0.38) and inorganic phosphorus (–0.52). The experimental procedures were approved by the Animal Welfare Committee of the University of Veterinary and Pharmaceutical Sciences (UVPS) Brno (no. 15/2015/2230 / FVHE).Šimek, V.; Zapletal, D.; Straková, E.; Pavlík, A.; Suchý, P.

Investigating Melatonin Supplementation on Maternal Hemodynamics and Offspring Programming

The objective was to examine effects of melatonin supplementation during late gestation on uterine artery hemodynamics, offspring growth, and endocrine profiles. Prior to day 170 of gestation, heifers were trained to the Calan feeding system. On day 190 of gestation, heifers (n = 20) were blocked by BW and then randomly assigned to one of two dietary treatments: 1) 20 mg of dietary melatonin per day (MEL) or 2) no melatonin supplementation (CON). Supplementation ceased on day 262 of gestation. A main effect (P \u3c 0.01) of treatment was observed for total uterine artery blood flow with it being increased in MEL vs. CON. An interaction (P = 0.008) was observed in calf body weight increasing at weeks 8 and 9 in MEL vs. CON. Dietary melatonin could be used to potentially increase uterine blood flow and calf body weight

Selling the press: Change and the family newspaper

Family members from six family-owned newspapers sold to media corporations in the past decade were interviewed to gain their perceptions on what it is like to grow up in, commit to, and ultimately sell the family newspaper after generations of ownership. A key premise of this study is that newspaper ownership is rarely approached from the perspective of the families who are relinquishing their newspapers to corporate ownership. Since family newspapers once dominated the nation\u27s media landscape, they are explored as the root of media consolidation and a critical place to start toward understanding what has fundamentally changed with the passage of countless community newspapers from family to corporate ownership. The combination of grounded analysis of interviews and rhetorical analysis of published texts provides data that both supports and extends current study of newspaper ownership, with emergent themes consistently reflecting the rise of Agency over Purpose (Burke, 1969a); focus on technical activities over personal relations (Halbwachs, 1992); and incursion of economic space into life space (Friedmann, 1988). In short, the family newspaper owners interviewed demonstrated particular awareness of the importance of people, place, and purpose in discussion of their experiences in the newspaper business
