BACKGROUND AND OBJECTIVES The obligate intracellular bacterium Chlamydia trachomatis causes sexually transmissible diseases in human. Timely and sensitive detection of this pathogen is very important. There are many cross-reactions in bacteriological and serological methods in detection of this type of pathogens. The aim of this study was to achieve a more specific antigen for serological tests...

A commercial aflatoxin detection ELISA kit, "RIDASCREEN(®) FAST Aflatoxin", was validated with corn samples naturally contaminated with aflatoxin and non-contaminated reference corn samples according to the Japanese Notification Method ShokuAnHatsu 0816-7. The trueness, intra-laboratory repeatability, intermediate precision, limit of detection and limit of quantitation were found to be 91%, 10%...

Avian salmonellosis due to Salmonella B and D serogroups has a great importance because of the public health and the economical losses in poultry industry. For accurate diagnosis of avian salmonellosis, a total of 126 chicken sera evaluated with a commercial Salmonella Enteritidis (SE) ELISA kit have been used to develop two indirect ELISA models using lipopolysaccharide (LPS) and purified flag...

A new enzyme linked immunosorbent assay (ELISA) kit which utilizes a monoclonal antibody against prostatic acid phosphatase (PAP) was compared with current radioimmunoassay (RIA) methodology which uses a polyclonal antibody. Both assays are double antibody immunoassays with the major difference being the method of antibody preparation. A study of intrarun precision using control material showed...

Helicobacter pylori, an important etiological agent in the development of gastritis, peptic ulcer and gastric carcinoma, can be detected by the enzyme-linked immunosorbent assay (ELISA). Our objectives were: (1) to evaluate the efficacy of a commercial ELISA kit (Pyloriset EIA-G III) in sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for ...

BACKGROUND Chagas disease caused by Trypanosoma cruzi is endemic in Latin America. Human infection is mainly spread by Triatominae insects. Other forms of transmission are congenital, blood transfusion and organ transplantation. METHODS Anti-T. cruzi antibodies were determined by enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) in 155 serum samples from mothers and their babies...

BACKGROUND Rapid identification of sepsis enables prompt administration of antibiotics and is essential to improve patient survival. Procalcitonin (PCT) is a biomarker used to diagnose sepsis in people. Commercial assays to measure canine PCT peptide have not been validated. OBJECTIVE To investigate the validity of a commercially available enzyme-linked immunosorbent assay (ELISA) marketed fo...

Early definitive diagnosis of dengue virus infection may help in the timely management of dengue virus infection. We evaluated the Standard Diagnostics (SD, South Korea) dengue virus nonstructural protein NS1 antigen enzyme-linked immunosorbent assay (SD dengue NS1 Ag ELISA) for the detection of dengue virus NS1 antigen in patients' sera, using a total of 399 serum samples in a comparison with ...

Cystic hydatid disease (hydatidosis) is one of the most important zoonosis that is caused by the larval stage of Echinococcus granulosus . As its diagnosis by clinical symptoms alone is difficult and confusing, serologic diagnostic techniques are used to confirm the disease. These techniques can also be used for   epidemiologic studies. The present study was performed with a commercial human en...
