Recombinant Toxoplasma gondii small heat shock protein HSP20, surface antigen SAG1 and dense granule GRA7 were analyzed by IgG-ELISA with serum samples of Toxoplasma infected humans grouped as I (IgG+, IgM+), II (IgG+, IgM-) and III (IgG-, IgM-). rHSP20 reacted against 80% and 62.5% of serum samples from groups I and II, respectively. rSAG1 was recognized by 85% of the samples from group I and ...

background: hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of echinococcus granulosus. diagnosis of hydatidosis is still an unresolved problem. serological tests using crude antigens for diagnosis of e. granulosus are sensi-tive, however their specificity are not satisfactory. therefore, who recommended spe-cific serological methods using specific antigens,...

objective(s): the aim of this study was to estimate effects of hyperbaric (hb) treatment by determination of cd15s and cd11b leukocyte proinflammatory markers expression.  in addition, this study describes changes in cd77 and cd34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. materials and methods:expression of cd11b and cd...

Accurate and timely diagnosis of dengue virus is important for early detection of dengue virus infection. In this study, the usefulness of the dengue NS1 antigen test was evaluated as a routine, rapid diagnostic test for dengue virus infection. A total of 208 sera from patients suspected of having dengue virus infection were collected and tested for dengue antibody, dengue genome and dengue NS1...

Thomsen-Friedenreich antigen (Galbeta1-3GalNAc), generally known as T-antigen, is expressed in more than 85% of human carcinomas. Therefore, proteins which specifically bind T-antigen have potential diagnostic value. Jacalin, a lectin from jack fruit (Artocarpus integrifolia) seeds, is a tetramer of molecular mass 66kDa. It is one of the very few proteins which are known to bind T-antigen. The ...

The Fya, Fyb, Jka, U, and Dib antigen site numbers and ultrastructural distribution patterns on the human erythrocyte membrane were determined using quantitative immunoferritin microscopy. For homozygous antigen-positive red cells, the average number of determinants per red cell was about 14,000 for Jka, 17,000 for Fya and Fyb, 19,000 for Dib, and 23,000 for the U antigen, assuming that the equ...
