An indirect fluorescent antibody technique has been developed for the serological diagnosis of gonorrhea. The selected strain(s) of Neisseria gonorrhoeae possesses a heat-labile surface antigen (L-antigen). Sera are diluted 1:10, and an aliquot is hear inactivated at 59 C for 30 min. The treated and untreated aliquots are then examined for human immunoglobulin G anti-L-antigen. In a prelimiary ...

This report describes the evaluation of a chemical test for T-antigen in rectal mucus as a screening test for colon cancer. The test, called the Mucus Strip Test, detects the disaccharide residue sialic acid-free fl-DGal(13)-D-GaINAc or T-antigen, which accumulates in mucus from malignant cells and colonic mucosa adjacent to cancer but not in normal mucosa. Participants were an unselected case ...

The antigen capture ParaSight-F test was evaluated during a drug sensitivity survey in a hypoendemic region of northern Vietnam. When only asexual blood forms of P. falciparum were considered, sensitivity of ParaSight-F was 100%, specificity 88% (95% CI 95-80%), positive predictive value 68% (95% CI 85-50%) and negative predictive value 100%. ParaSight-F proved very convenient for rapid screeni...

background: cystic echinococcosis caused by the metacestode of echinococcus granulosus is a major problem in both humans and domestic animals health. there-fore, a standardized and approachable diagnostic tool (rapid tests) for the serodiag-nosis of cystic echinococcosis (ce) is still needed. methods: in the present work, antigen b labeled with gold nanoparticles was used to detect antibodies a...

Animal schistosomiasis caused by Schistosoma bovis is a veterinary problem in many areas of the world. It affects a large number of animals and causes important economic losses in livestock production. The 22.6 kDa antigen is a tegumental protein of unknown function, restricted to schistosomes. In S. bovis it has been identified in the tegument and in an excretion-secretion extract, consisting ...

Background and Objectives: Iran, as a developing country, is experiencing high burdens of Helicobacter pylori (Hp)-associated non-communicable diseases. Hp stool antigen test (HpSA) is widely used as an inexpensive and feasible noninvasive method to diagnose Hp infection, instead of invasive approaches. The current study aimed at evaluating th...

An easy-to-use LabVIEW tool for ADC testing is presented. The tool provides a comprehensive collection of data processing algorithms which are able to ensure the best possible results in ADC testing, and to help to recognize bad parameter settings during the measurement. The core routines are migrated without change from our well tested MATLAB toolbox. Full test of the ADC can be done easily by...

Background: A new rapid Immunochromatographic test (ICT) kit (MPT64 TB Ag Kit) for detection of MPT64 Antigen in M. tuberculosis (MTB) isolates used for rapid identification of MTB isolates developed by SD (Standard Diagnostics) Bio line, South Korea was evaluated. The ICT is a rapid, reliable and cheaper method that can be used instead of conventional biochemical tests for confirming MTB in cu...
