Burkholderia pseudomallei is the causative agent of melioidosis. In northeast Thailand, this gram-negative bacterium is a major cause of mortality from septicemia. The definitive diagnosis of this disease is made by bacterial culture. In this study, we produced a monoclonal antibody (MAb) specific to the 30-kDa protein of B. pseudomallei by in vivo and in vitro immunization of BALB/c mice with ...
In a recent review of the literature (1,2), many of the problems dealing with cellular agglutination caused by ricin are presented and discussed. Although this phenomenon was first described in 1888 by Stilhnark, reactions involved in the agglutination of cells are poorly understood. The present report is concerned with factors which affect agglutination. Data are presented which show that eryt...
A one-stage macroscopic test for platelet agglutination was used to study the effect of thrombin and thrombin-cation mixtures on washed platelets. Conclusions regarding platelet agglutination are as follows: (a) Canine, bovine, or human thrombin alone does not cause agglutination of canine or human platelets. (b) Thrombin with calcium or magnesium causes rapid platelet agglutination. Both calci...
In order to study the relationship between hrmolysin / ashesins of Escherichia coli and occurrence of urinary tract infection ( UTI), the capacity of 570 isolated E.coli in agglutination of human or guinea pig erythrocytes and their lysis were tested. These isolates were obtained from the urine of patients with bacteriuria and from the stool of healthy people. Three patterns of hemagglutinat...
Background: A β-mercaptoethnol (β-ME)-treated promastigote antigen of L. donovani was successfully employed in direct agglutination test (DAT) for the diagnosis of visceral leishmaniasis (VL). Objective: The β-ME-treated antigen was further incorporated into an enzyme-linked immunosorbent assay set-up (β-ME ELISA) and evaluated for VL diagnosis against outcome of reference freeze-dried DAT (FD-...
Background: Visceral leishmaniasis (VL) is an endemic disease in some parts of Iran. Many techniques have been used for diagnosis of VL, among which the urine based la-tex agglutination test (KAtex) is a promising one. Objective: To compare three diag-nostic tests of VL including KAtex, ELISA and Direct Agglutination Test (DAT) in VL patients and healthy controls in the south west of Iran. Meth...
The binding to mammalian cells of piliated enteric bacteria and the inhibition of the binding by antibodies to purified pili were studied. The target cells were epithelial cells from human bucca and human and rat urinary tracts, erythrocytes from various species, and Saccharomyces cerevisiae cells. The strains were selected to represent the two main agglutination patterns of enteric bacteria: m...
