background: strongyloidiasis is mostly an asymptomatic infection and diagnosis of latent infec­tions is difficult due to limitations of current parasitological and serological methods. this study was conducted to set up a pcr-based method for molecular diagnosis of strongyloides stercor­alis infection by detection of copro-dna in stool samples. methods: a total of 782 fresh stool samples were c...

A quantitative fluorometric immunoassay (FIAX) was adapted for the detection of serum antibodies to Brucella abortus in cattle. Results are expressed in nanograms of immunoglobulin binding the antigen carrier. The FIAX was compared with the standard tube agglutination, Rivanol precipitation, and complement fixation tests, using 285 serum samples from vaccinated, challenged, or control cattle. L...

A novel serological test, IPAzyme Chlamydia (Savyon Diagnostics Ltd., Beer Sheva, Israel), was compared with an enzyme immunoassay (EIA) for the ability to detect serum immunoglobulin G and A antibodies in the diagnosis of acute chiamydial pelvic inflammatory disease. In comparison with cell culture, which is the "gold standard," IPAzyme Chlamydia and EIA exhibited sensitivities of 63 and 68% a...

We previously derived a typology of schizophrenia from a latent class analysis of 447 first-contact non-affective functional psychotic patients from a defined catchment area. Here, using the same sample, we show that the three subtypes, 'neurodevelopmental' (Type A), 'paranoid' (Type B) and 'schizoaffective' (Type C) have different premorbid, phenomenological and treatment response characterist...
