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) ...

Background Wheat is one of the most important food allergen sources. Using natural wheat allergen extracts for serological diagnosis of wheat-induced food allergy false positive test results are frequently obtained, in particular in grass pollen allergic patients. Therefore, Tri a 19, an omega-5-gliadin, which is known as a major allergen in wheat dependent exercise induced anaphylaxis (WDEIA) ...

Methods: Seventeen groups of 30 to 60 sows and gilts in seven herds were monitored over a 2-year period by serological testing for the pathogens listed above. Litter size, number of stillborn (including mummies), average weaning weight, preweaning deaths, and interfarrowing interval were recorded for the sows that were tested. Multiple linear regression analyses were performed to evaluate the a...

A commercial DNA probe kit (Gen-probe) for the detection of rRNA from legionellae was evaluated for its accuracy in diagnosing Legionnaires' disease in 167 patients with pneumonia. The test was performed on freshly obtained clinical respiratory tract samples. Cultures and direct immunofluorescence antibody (DFA) staining of the samples and serological tests were performed simultaneously for all...

A factor present in fresh normal human or guinea pig serum enhances the primary atypical pneumonia (PAP) antibody titers in serological reaction with its homologous virus as tested by indirect fluorescent antibody staining. This factor is not properdin. It has many properties similar to complement but may not be identical with complement. The addition of this enhancement factor to human sera co...
