A novel dot blot test for trichinella spiralis antigen detection

Infectivity of Trichinella Spiralis Larvae

Time of survival and infectivity of Trichinella spiralis larvae in pig muscle tissue, buried at various depths in the ground were assessed. In the pork pieces the number of infective larvae was 250 ML/g. Meat originated from pig halves was divided in 39 equal pieces, 0.7 kg each, disposed in three groups of 1 3, and buried in depths of 30, 50, and 100 centimeters respectively. The pork was dug ...

Immobilization of DNA Aptamers on Polyester Cloth for Antigen Detection by Dot Blot Immunoenzymatic Assay (Aptablot)

A simple dot blot immunoenzymatic assay system was developed using polyester cloth coated with an oligo-DNA aptamer to provide a high-affinity macroporous surface for the efficient capture of a model protein analyte (thrombin) in complex sample matrices such as foods. Bound thrombin was detected immunoenzymatically using a peroxidase-linked antithrombin antibody and a chromogenic substrate. A u...

Development of a recombinant protein-based dot-blot hybridization assay for the detection of antibody to chicken infectious bronchitis virus

Nucleocapsid (N) protein of infectious bronchitis virus (IBV), one of the viral structural proteins, inducesstrong antibody response in natural infection. In this study, a simple, recombinant N protein-based dot-blottest was developed to serologically examine chicken serum samples for the presence of IBV antibody.Initially, 72 serum samples were tested for the presence of IBV antibody using a c...

Experimental and immunological comparison of Trichinella spiralis and Trichinella nativa

Development of a novel antigen detection test for histoplasmosis.

Histoplasmosis is an important systemic fungal infection, particularly among immunocompromised individuals living or travelling in areas of endemicity, who, without antifungal therapy, may develop a progressive disseminated fatal infection. For such patients, the detection of antibody responses by immunodiffusion or complement fixation test is of limited use. In contrast, the detection of Histo...
