coagulase positive staphylococcus intramammary infections in primiparous dairy cows
Journal of Dairy Science, 1994Co-Authors: J R Roberson, Dale D Hancock, T E BesserAbstract:Objectives were to determine the Prevalence of coagulase-positive staphylococcal IMI in primiparous cows at first parturition, to contrast the differences in coagulase-positive staphylococcal IMI in primiparous cows at parturition in herds with high and low Prevalences of coagulase-positive staphylococcal IMI in the lactating herd, and to determine the percentage of primiparous cows having persistent coagulase-positive staphylococcal MI. Milk samples were collected aseptically from cows at the start and end of the study, at dry-off, and at parturition. Herds (n = 18) were split evenly into two categories: high (>10%) or low (<5%) Prevalence of coagulase-positive staphylococcal IMI. At the start, the mean Prevalence of coagulase-positive staphylococcal IMI in high Prevalence herds was 30%, ranging from 13 to 65%, and in low Prevalence herds was 2%, ranging from 0 to 5%. Overall the Prevalence of coagulase-positive staphylococcal IMI in primiparous cows at parturition was 8.1% (67 of 828), ranging from 0 to 27%. Although primiparous cows from high Prevalence herds had a higher Prevalence of coagulase-positive staphylococcal IMI (9.2%; 40 of 436) at parturition than did primiparous cows from low herds (6.9%; 27 of 392), the difference was not significant. Of primiparous cows with coagulase-positive staphylococcal IMI at parturition, 43% had coagulase-positive staphylococcal IMI at least 2 mo after parturition. Primiparous cows with coagulase-positive staphylococcal IMI at parturition may represent significant reservoirs of infection to uninfected herdmates.

use of a crude extract or purified antigen from first instar cattle grubs hypoderma lineatum for the detection of anti hypoderma antibodies in free ranging cervids from southern spain
Medical and Veterinary Entomology, 2010Co-Authors: Rosario Panadero, C Martinezcarrasco, L Leonvizcaino, C Lopez, P Diezbanos, M P Morrondo, F D AlonsoAbstract:During the 2003–2005 hunting seasons, a total of 120 Cervidae, including 39 red deer (Cervus elaphus hispanicus) and 81 fallow deer (Dama dama), were examined for subcutaneous myiasis. Animals were shot from January to June in southern Spain. Specific antibodies against Hypodermatinae (Diptera: Oestridae) were detected by indirect enzyme-linked immunosorbent assay (iELISA) using a crude larval extract (CLE) and a purified antigen [hypodermin C (HC)] obtained from first instars of Hypoderma lineatum (De Villers) (Diptera: Oestridae). Hypoderma actaeon Brauer was the only species detected in this study, which represents the first confirmation of this species in fallow deer from Spain. The overall Prevalence of animals presenting subcutaneous larvae (14.2%) was considerably lower than the Prevalences determined by iELISA with CLE (43.3%) and HC (40.0%). Red deer showed a higher Prevalence of Hypoderma than fallow deer. The concordance between larval examination during the hunting season and iELISA using both antigens was low, whereas the concordance between the CLE and HC ELISAs was good. Larval antigens obtained from H. lineatum constitute a good tool for the diagnosis of H. actaeon in Cervidae, especially when the hunting season does not coincide with the maximum presence of larvae on the back.

the metabolic syndrome Prevalence and associated risk factor findings in the us population from the third national health and nutrition examination survey 1988 1994
JAMA Internal Medicine, 2003Co-Authors: Yong Woo Park, Shankuan Zhu, Stanley Heshka, Mercedes R Carnethon, Latha Palaniappan, Steven B. HeymsfieldAbstract:Coronary heart disease (CHD) is the leading cause of death in the United States.1 Factors associated with an increased risk of developing CHD that tend to cluster in individuals include older age, high blood pressure, a low level of high-density lipoprotein (HDL) cholesterol, a high triglyceride level, a high plasma glucose concentration, and obesity.2 These associated risk factors have been called syndrome X,3 the insulin resistance syndrome,4 or the metabolic syndrome.5 The mechanisms underlying the metabolic syndrome are not fully known; however, resistance to insulin-stimulated glucose uptake seems to modify biochemical responses in a way that predisposes to metabolic risk factors.3,6,7 Insulin resistance is thought to be primarily due to obesity or an inherited genetic defect.8 As the Prevalence of obesity increases in the United States, the Prevalence of the metabolic syndrome may be expected to increase markedly. Estimates of the Prevalence of the metabolic syndrome have varied substantially in part because of the variability of evaluated populations and of diagnostic criteria.9 The recent Third Report of the National Cholesterol Education Program Adult Treatment Panel (ATP III) included clinical diagnosis guidelines for the metabolic syndrome.10 Compared with findings from earlier studies3-5 and World Health Organization guidelines, the new ATP III defines criteria readily measured in clinical practice. These consensus-generated guidelines provide the opportunity to assess the overall Prevalence of the metabolic syndrome in the US population according to an accepted standard definition. In an initial study, Ford et al11 reported un-adjusted and age-adjusted metabolic syndrome Prevalences of 21.8% and 23.7%, respectively, for the US population. The objectives of this study are to examine the Prevalence of the metabolic syndrome by ethnicity, age, body mass index (BMI) (calculated as weight in kilograms divided by the square of height in meters), socioeconomic status, and lifestyle factors.
