A dipstick assay, based on Leishmania infantum antigen, for the rapid detection of Leishmania-specific antibodies in canine serum samples was developed and evaluated. After determination of optimal dipstick test conditions, test performance was compared with two existing serological tests, i.e., the direct agglutination test (DAT) and the fast agglutination screening test (FAST). In the present...
Serological relationships between new isolates of Trypanosoma cruzi from a single locality have been examined by direct agglutination and immunodiffusion, and compared with established strains. The strains were divided into three groups according to the absorption properties of their precipitinogens. The three groups were defined by the same characteristics as those in which strains of wide-ran...
The results of seven serologic tests for diagnosis of human brucellosis were evaluated. The titrated Rose Bengal test, microagglutination test, microtiter-adapted Coombs test, and immunocapture-agglutination test (Brucellacapt) were positive for all sera from patients with acute brucellosis. The immunoglobulin G (IgG), IgM, and IgA commercial enzyme immunoassays (ELISAs) failed to show specific...
The agglutination responses of three Drosophila cell lines to concanavalin A and wheat germ agglutinin have been examined. Although the cell lines were originally derived from late embryonic stages of the Ore-R strain of Drosophila melanogaster. they show quantitative differences in lectininduced agglutination. Line 1 cells were least agglutinable with both lectins. All three cdl lines reached ...
OBJECTIVE Visceral Leishmaniasis (VL) is highly prevalent in Bihar, India. India and its neighbours aim at eliminating VL, but several knowledge gaps in the epidemiology of VL may hamper that effort. The prevalence of asymptomatic infections with Leishmania donovani and their role in transmission dynamics are not well understood. We report data from a sero-survey in Bihar. METHODS Demographic...
Despite the rapid development of knowledge it still remains fundamental that mistakes within the ABO and Rhesus systems are responsible for virtually all fatal mismatched transfusions. It therefore cannot be too highly stressed that the careful preliminary grouping of the bloods of all patients for transfusion is of prime importance, irrespective of whether there is a previous record of their b...
A new direct agglutination test (DAT) for use with urine samples for the diagnosis of visceral leishmaniasis (VL) has been developed and compared with the conventional DAT with serum samples and our previously reported enzyme-linked immunosorbent assay (ELISA) with urine samples (urine ELISA). The new DAT, in which anti-human IgG was used as enhancing antibody, was tested with urine samples fro...
Anti-D immunoglobulin; BioVue column agglutination test; Quality control; Haemolytic disease; Anti-Rh(D) titration; Rh-factor Abstract The preparation anti-D immunoglobulin is an important therapy for both treatment and protection. Titer of anti-D immunoglobulin preparation is an important factor to determine the dose of treatment. Many methods are used to evaluate the titer of anti-D immunoglo...
Techniques have been devised for studying quantitatively the effects of air ions on microorganisms suspended in small drops. In smog-contaminated atmospheres moderate concentrations of positive and negative air ions exerted a protective effect on staphylococci by delaying the drop in pH customarily observed and by diminishing the rate of evaporation. In clean air higher concentrations of positi...
background: lectins the multivalent carbohydrate binding proteins are also employed to ascertain differentiation and characterization of the specific cell surface carbohydrate ligands/ receptors of different cell types including spermatozoa and posses novel biomedical importance. objective: sf50 the sialic acid specific lectin was employed on goat cauda epididymal spermatozoa to investigate its...
