cryptococcosis has become the fourth leading life-threatening opportunistic infection in patients with aids, but also occurs in non-aids patients. in view of the increasing numbers of infection during last decade in iran, use of rapid, sensitive and specific test for diagnosis of cryptococcal disease has become important than ever. we aimed to produce the reagents for latex cryptococcal antigen...

background because of the economic importance of the arab race horses and also the role of toxoplasma gondii and neospora spp. in abortion and reproductive failure of these animals, we decided to perform this study. objectives we designed this study to investigate the seroprevalence of anti-toxoplasma gondii and anti-neospora spp. antibodies in arab horses from 12 cities of khuzestan province i...

Lipopolysaccharide (LPS) is a major surface component of most Gram-negative bacteria and recognized by immune cells as pathogen-associated molecules. Antibodies against O antigens can provide protection infection vaccines have been developed conjugating to carrier proteins enhance immunogenicity. This study aims produce antigen from Escherichia coli analyze the in vivo test results poultry usin...

In this study a device was designed to detect human blood group using the ABO method which is integrated with oxygen saturation meter. This tool can agglutination or non-agglutination reactions in samples that have been treated antisera and will then be read by three TCRT5000 sensors are reflective used as detectors of A, B Rhesus antigens when occur on paper. sample test. addition, MAX30100 se...

One hundred sera from 49 patients with glandular toxoplasmosis were examined by a latex agglutination test, the dye test, an indirect haemagglutination test, and a double antibody sandwich enzyme linked immunosorbent assay (ELISA) for antitoxoplasma IgM. The results support previous findings that the dye test, indirect haemagglutination test, and latex agglutination test measure different antib...

The association between occupancy of the von Willebrand factor (vWf) receptor glycoprotein (GP) Ib, agglutination, and the assembly and composition of the cytoskeletal core was studied in 125I-surface-labeled aspirin-treated washed platelets. Binding of ligands to GPIIb-IIIa and platelet aggregation were abolished by addition of EDTA. Platelet agglutination induced by bovine vWf generated a com...

INTRODUCTION Measurement of alloantibody titer to a red cell antigen (ABO titers) is an integral part of management of ABO incompatible kidney transplants (ABOiKT). MATERIAL AND METHODS There are different methods of titer estimation. Alloantibody detection by tube titration and Gel agglutination columns are accepted methodologies. It is essential to find the difference in titers between the ...

Hunt, D. E. (Charles V. Chapin Hospital, Providence, R.I.) and P. L. Carpenter. Sterols as components in the mating reaction of Hansenula wingei. J. Bacteriol. 86:845-847. 1963.-Agglutinative mating strains 5 and 21 of the yeast Hansenula wingei did not agglutinate after the cells of these two strains were treated with nystatin. The agglutination-inhibiting action of this antibiotic could not b...
