Arcobacter cibarius sp. nov., isolated from broiler carcasses.
PCR tests but that yielded an amplicon in an Arcobacter genus-specific PCR test were isolated from 13 unrelated broiler carcasses. Numerical analysis of the profiles obtained by SDS- PAGE of whole-cell ...
Detection of HCV antibodies in oral fluid.
fluid 1:10. Testing paired samples gave a concordance of 85.6% (125/146), yielding no more accurate results. These findings suggested that the modified ELISA method for anti- HCV detection in oral fluid ...
Conditional expression of type I interferon-induced bovine Mx1 GTPase in a stable transgenic vero cell line interferes with replication of vesicular stomatitis virus.
expression of physiologic levels of bovine Mx1. Expression of the transgene caused a dramatic decrease in cytopathic efficiency and a 500-5000-fold yield reduction of the Indiana and New Jersey serotypes of ...
Virologic versus cytologic triage of women with equivocal Pap smears: a meta-analysis of the accuracy to detect high-grade intraepithelial neoplasia.
ASCUS or worse was 81.8% (95% CI = 73.5% to 84.3%) and 57.6% (95% CI = 49.5% to 65.7%), respectively. Repeat cytology that used higher cytologic thresholds yielded substantially lower sensitivity but ...
Decision support tools for clinical diagnosis of disease in cows with suspected bovine spongiform encephalopathy.
movement or carriage, increased alertness behavior, reduced milk yield, teeth grinding, and temperament change. Ataxia did not appear to be a specific sign of BSE. A classification and regression tree was ...
Estimation of the minimum detectable value for the determination of PCBs in fatty food samples by GC-ECD: a curvilinear calibration case
p.413- 418 (2003) Keywords: alternatives at Calibration Case estimation food Impact IS method methods MODEL models ON PCB Pcbs RANGE regression Regression model result results Sample Samples Yield ...
Metaanalysis of the accuracy of rapid prescreening relative to full screening of pap smears.
detected only by RPS (2.8%; CI 0.0-5.8%). This is comparable to the proportion of false-negative smears detectable by RR. CONCLUSIONS: Rapid prescreening has a high yield for severe dysplasia and shows ...
Linearity of calibration curves: use and misuse of the correlation coefficient
Statistical Test tests use VALIDATION values variables Yield Abstract: The correlation coefficient is commonly used to evaluate the degree of linear association between two variables. However, it can be shown ...
First evidence of Johne's disease in farmed red deer (Cervus elaphus) in Belgium.
the intestine. Although Ziehl-Neelsen staining yielded no positive results, a catarrhal focal necrotic enteritis associated with a granulomatous lymphadenitis compatible with Johne’s disease was ...
Comparison of biological activities of natural and recombinant chicken interferon-gamma.
obtained in the supernatants of infected insect cells. On the other hand, yields of the E. coli produced ChIFN-gamma rarely exceeded 100 microg/ml after purification steps and although it was also able to ...
