Objective(s): Hydatidosis is a zoonotic infection and endemic in Iran. Due to the serological cross-reactivity (of sera) with other parasitic infection, diagnosis of hydatid cyst is considered to be problematic. In this regard, application of recombinant antigens improves serological diagnosis for human hydatidosis. Here, we present an ELISA test based on B8/2 recombinant antigen of Echinococcu...
Rapid antibody detection has been used widely as a diagnostic aid in the diagnosis of tuberculosis (TB), especially for bacterium-negative TB. We evaluated the diagnostic value of four commercial antibody detection kits with 501 sera from TB patients and controls. The sensitivities and specificities of the four kits were as follows: (1) Rapid test A 71.8% and 91.4% (85.5% for non-TB diseases an...
The potential uses of serological tests that detect HCV core antigens in biological fluids are highlighted. The most common serological tests utilized to detect exposure to HCV rely on the detection of antibodies to HCV. However, these tests cannot distinguish between individuals who have resolved their infection and those who remain actively infected with HCV. By contrast, the HCV core antigen...
The 2 2 model of perfectionism examines the relation between four subtypes of perfectionism and psychological adjustment (Gaudreau & Thompson, 2010). Researchers have investigated subtypes of perfectionism using common multivariate statistical analyses. The development of a new measure is warranted to evaluate whether individuals can, with a decent degree of certainty, assess by themselves thei...
Three-hundred sixty sera from unselected patients attending two London venereal disease clinics were examined by a microimmunofluorescence test. Eleven egg-grown serotypes of Chlamydia trachomatis and the so-called "fast" strain SA2(f) were used as antigens. Of the 360 sera tested, 119 (33%) reacted to a titer of 1:16 or above with at least one antigen. Of these positive sera, over 50% cross-re...
Serological classification of Pseudomonas aeruginosa by the slide agglutination test with live organisms was studied, based on the O antigen schema adopted by the international expert panel sponsored by the Subcommittee on Pseudomonas and Related Organisms of the International Committee on Systematic Bacteriology. The typing results obtained by the slide test with well-absorbed O sera were iden...
The diagnostic value in coeliac disease of circulating antibodies to casein, crude gliadin, and alpha gliadin was assessed using an adaption of the enzyme linked immunosorbent assay system. alpha Gliadin was the only antigen which consistently separated 26 patients with untreated coeliac disease from 26 normal controls and 13 patients with chronic inflammatory bowel disease. The mean assay inde...
1197 The mechanism for the air in the mediastinum is suggested as being due to rupture of marginal pulmonary alveoli, allowing the development of pulmonary interstitial emphysema. This then tracks through the fascial planes at the lung hilum, and from there into the mediasti-num and neck. There was no obvious underlying lung disease in our patient, and no further investigations were indicated. ...
African swine fever (ASF) is an infectious and economically important disease of domestic pigs. The absence of vaccine renders the diagnostic test the only tool that can be used for the control of new outbreaks of the disease. At present, the enzyme-linked immunosorbent assay (ELISA) test is the most useful method for large-scale ASF serological studies, although false positives have been detec...
BACKGROUND Interpretation of serological assays in Lyme borreliosis requires an understanding of the clinical indications and the limitations of the currently available tests. We therefore systematically reviewed the accuracy of serological tests for the diagnosis of Lyme borreliosis in Europe. METHODS We searched EMBASE en MEDLINE and contacted experts. Studies evaluating the diagnostic accu...
