Analysis of serum from a patient with cutaneous leukocytoclastic vasculitis showed a mixed cryoglobulin with a monoclonal IgM kappa-antiglobulin component (6.5 mg/ml), strong rheumatoid factor activity (latex titre 1/5000), and positive serological tests for syphilis (fluorescent treponemal antibody-absorbed and Treponema pallidum haemagglutination assay). After removal of antiglobulin activity...

A test for farmer's lung is described employing the indirect fluorescent antibody technique. The test compared very favourably with standard precipitin tests, detecting 88% of a series of positive cases, as opposed to 38% detected by a precipitin test. The fluorescent antibody test, in addition, introduced some measure of quantitation of the serological response in the disease.

To assess the value of serological tests in diagnosing and monitoring the response to treatment of syphilis in patients infected with the human immunodeficiency virus (HIV), case notes of eight homosexual men with a history of treated syphilis, positive reactions to serological tests for syphilis, and documented subsequent conversion to HIV seropositivity were studied. No change was noted in se...

Caprine arthritis encephalitis (CAE) is a chronic disease caused by a small ruminant lentivirus (SRLV), which causes significant losses in goat breeding. The actual state of animal infection with SRLV is difficult to determine due to a complex pathogenesis of the virus, including factors such as delayed or intermittent seroconversion in serological tests. Several serological techniques are avai...

The WHO was created in 1950 with the prime assignment to fight tuberculosis. To this end, it granted immunity against any prosecution. French state immediately exploited advantage impose BCG vaccine developed by Pasteur institute, although known, both institute and WHO, be deficient. It poorly attenuated some of its strains favor spread TB. also favors leprosy. knew nevertheless supported fraud...

EU Regulation 998/2003 requires the serological testing of rabies-vaccinated dogs and cats in approved laboratories using serum neutralization tests prior to movement of pet animals between certain EU member states and before pet animals are imported from unlisted third countries. Serum neutralisation tests are also used for measuring the efficacy of oral rabies vaccination programmes conducted...

INTRODUCTION The aim of this study was to evaluate the serological cross-reactivity between Leishmania sp. and other canine pathogens. METHODS Positive serum samples for Ehrlichia canis, Babesia canis, Toxoplasma gondii, Neospora caninum and Trypanosoma cruzi were tested using three serological methods enzyme linked immunosorbent assay (ELISA), indirect immunofluorescent antibody test (IFAT) ...
