INTRODUCTION Chlamydia antibody testing (CAT) in serum has been introduced as a screening method in the infertility workup. We evaluated the test characteristics of two ELISA tests compared to micro-immunofluorescence tests (MIFs). MIFs are considered the gold standard in the C. trachomatis IgG antibodies detection. We also compared the accuracy of all CAT tests in predicting tubal subfertility...

Pulmonary parasitic diseases have become a frequent feline condition. Aelurostrongylus abstrusus, Troglostrongylus brevior and Capillaria aerophila appear to be the main pathogenic factors. Felines that are affected may display respiratory as well non-specific symptoms. Diagnostic methods include copromicroscopic, serological molecular detection, whereas treatment should both symptomatic electi...

CONTEXT The most frequently used methods for detecting antibodies are the indirect immunofluorescence test and the enzymatic immunoassay (ELISA). The polymerase chain reaction is a molecular biology technique in which the production of large amounts of specific DNA fragments is induced from very low concentrations of complex substrates aloowing the detection of very low amounts of viral particl...

BACKGROUND Herpes simplex virus (HSV) type-specific serological tests are now widely available, but indications for their use have not been well defined. The California Sexually Transmitted Diseases (STD) Controllers Association convened a committee of clinicians and researchers to make recommendations for the use of type-specific HSV type 2 (HSV-2) serological tests. METHODS By means of a sy...

BACKGROUND Celiac disease is an immune-mediated inflammation of the small intestine caused by sensitivity to dietary gluten in genetically sensitive individuals. OBJECTIVES In this study, we aimed to evaluate the predictive value of tissue transglutaminase (tTG) antibodies for the diagnosis of celiac disease in a pediatric population in order to determine if duodenal biopsy can be avoided. ...

A new method of determining class II HLA antigens by genotyping with HLA DNA probes is described. This method compares favourably to the traditional serological methods.
