BACKGROUND Current practice for diagnosis of Q fever, caused by the intracellular pathogen Coxiella burnetii, relies mainly on serology and, in prevaccination assessment, on skin tests (STs), which both have drawbacks. In this study, C. burnetii-specific interferon γ (IFN-γ) production was used as a new diagnostic tool for previous Q fever, circumventing most of these drawbacks. Our aim was to ...
Q fever is a potentially severe disease which can occur in large outbreaks of acute infections and is a possible bioterrorism agent. In order to lessen the delay in diagnosing acute Q fever, we compared LightCycler Nested PCR (LCN-PCR), a rapid nested PCR assay that uses serum sampled early during the disease as a specimen and the LightCycler as a thermal cycler, to serology by indirect immunof...
Sensitive and precise serology assays are needed to measure the humoral response to antigens of respiratory syncytial virus (RSV) following natural infection or vaccination. We developed and evaluated a collection of electrochemiluminescent (ECL) serology assays using four RSV antigens (F, N, Ga and Gb). To assess the merits of ECL technology, the four ECL serology assays were evaluated using a...
The study aims were to determine the prevalence of positive syphilis serology and meningovascular neurosyphilis (NS) in patients admitted with transient ischaemic attack (TIA) and stroke to a tertiary hospital serving a culturally diverse community. A retrospective cohort analysis was conducted using routinely collected administrative data and medical records to identify patients admitted with ...
Objectives: The demonstration of the serological test importance in the diagnosis of the Congenital Toxoplasmosis. The Method: The serological test was performed through the micro enzymatic immunology technique, on a lot of 87, new born suckling babies. Along with the laboratory investigations the babies were also clinical, oftalmological and neuron-imagistic examined. Results: The diagnosis of...
Antibody (IgG) responses to salivary gland homogenate and to a recombinant salivary protein from the sand fly Lutzomyia longipalpis were investigated using sera from children living in an endemic area of visceral leishmaniasis in Brazil. We classified children into four groups according to their responses to Leishmania antigen: (Group I) positive serology and positive delayed type hypersensitiv...
Origin Attempts carried out about the year 1920 at the Kaiser-Wilhelm Institute of Experimental Therapy in Berlin to culture treponemes from eighty to ninety patients with primary syphilis, were successful in seven of these cases. One of the strains obtained, denoted as B 36, was said to have remained pathogenic for rabbits (Wassermann and Ficker, 1922). Reiter (1960), who continued the work of...
aim : the aim of this study was to discuss the prevalence of celiac disease (cd) in dyspeptic patients. background : although severe mucosal abnormality with villous atrophy (lesions marsh iii) is at present the gold standard for the diagnosis of cd, presentation with non-specific microenteropathy (marsh i-ii) with positive serology is also common. patients with dyspepsia, specific cd antibodie...
