A molecular survey was performed for identification Theileria spp in sheep and ticks during from 2010-2011 in Fasa and Kazeroun areas, Fars province, Iran. A total of 100 sheep from different flocks were clinically examined and blood samples with ixodid ticks collected. The prepared blood smears from capillary vein of ear were stained with giemsa methods and examined by using light microscope. ...
Syphilis is a health problem of increasing incidence in recent years that may have severe complications if not diagnosed and treated at an early stage. There are many diagnostic tests available for syphilis, but there is no gold standard, and diagnosis therefore usually relies upon a combination of tests. In this multicenter study, we evaluated the treponemal Elecsys syphilis assay for use in t...
Compared to routine isolated colony-based methods, direct testing of bacterial pellets from positive blood cultures reduces turnaround time for reporting of antibiotic susceptibility. The aim of this study was to compare the accuracy, and precision, of a rapid method for direct identification and susceptibility testing of blood cultures with the routine method used in our laboratory, using Vite...
An automated headspace gas-chromatographic method has been developed for the determination of acetone in the milk, blood and urine of dairy cows. Five ml samples were saturated with 2 g of sodium chloride and equilibrated for 30 min at 90 degrees C in a Hewlett-Packard HP 19395 A automatic headspace sampler. The headspace volatiles were transferred without splitting to a 25 m x 0.3 mm x 0.4 mic...
A passive hemagglutination test (PHA) for detecting human immunodeficiency virus type 1 antibodies in serum samples by using envelope glycoprotein (gp160)-coupled sheep erythrocytes was described earlier (M.B. Vasudevachari, K. U. Uffelman, T.C. Mast, R.L. Dewar, V. Natarajan, H.C. Lane, and N.P. Salzman, J. Clin. Microbiol. 27:179-181, 1989). In the study reported here, the applicability of th...
BACKGROUND The aim of this study was to evaluate a newly developed PCR-based reverse blot hybridization assay (PCR-REBA), REBA Sepsis-ID (M&D, Wonju, Korea), to rapidly detect the presence of bacteremia and antimicrobial resistance gene in blood culture samples. METHODS One thousand four hundred consecutive blood culture samples from patients with a delta neutrophil index greater than 2.7% we...
A microsampling cup procedure is described for rapid, precise determination of copper in plasma. Conventional Delves-cup atomic absorption spectrometry does not yield usable copper signals with blood plasma samples. Analytical sensitivity was improved 11-fold by use of cups fitted with an axial hole, a triangular cup-holding loop, and a smaller-bore absorption tube. The modified procedure yield...
BACKGROUND Duffy (FY) blood group genotyping is important in transfusion medicine because Duffy alloantibodies are associated with delayed hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. In this study, FY allele frequencies in Thai blood donors were determined by in-house PCR with sequence-specific primers (PCR-SSP), and the probability of obtaining compatible bl...
