The diagnosis of chronic pulmonary aspergillosis (CPA) depends on the radiologic image and the identification of specific antibodies. The present study aimed to evaluate accuracy parameters of enzyme-linked immunosorbent assay (ELISA) and of the determination of serum galactomannan level in the diagnosis of patients with CPA, comparing these results with the double agar gel immunodiffusion (DID...

A microtiter enzyme-linked immunosorbent assay (ELISA) has been developed for the titration of antibodies against scrub typhus in human and animal sera. Scrub typhus rickettsiae were grown in monolayers of irradiated mouse LM3 cells and separated from host cell materials by differential centrifugation, filtration through a glass filter (AP-20, Millipore Corp.), and isopycnic banding in Renograf...

BACKGROUND Brucellosis is the most common bacterial zoonosis, and serological tests are routinely used in brucellosis control and eradication programs. In order to improve the accuracy of serological diagnostic method used in bovine brucellosis detection, this study developed an improved competitive ELISA with higher specificity and good sensitivity. RESULTS This study prepared 12 monoclonal ...

A sensitive ELISA was developed for the detection of amoxicillin (AMX) in serum, urine, and milk. The ELISA used an indirect competitive method produced by coating the plate with ovalbumin conjugated with AMX hapten. Antibodies against AMX-BSA were detected by a goat-antirabbit antibody conjugated with peroxidase. Calibration standard curves ranged from 1.28 ng/mL to 20 microg/mL [IC(50) (inhib...

We investigated the performance of the DPP(®) canine visceral leishmaniasis (CVL) rapid test, a novel immunochromatographic assay launched by BioManguinhos (Brazil), which was recently included in the new Brazilian protocol for screening CVL in serological surveys. The present study compared the DPP(®) with the ELISA and IFA produced by BioManguinhos (Brazil) both with L. major-like antigens an...

BACKGROUND Pigeon breeder's disease is an extrinsic allergic alveolitis in the lungs of sensitised people, caused by hypersensitivity reactions to inhaled pigeon antigens. Antigens from different sources of the animal are used for diagnostic purposes, with serum being the most widely used. Bloom is rarely used; very little is known of its antigenicity and diagnostic performance, particularly wh...

In this paper, we employ the view model given by Bertino to propose a new design approach for a secure multi-level object-oriented database system. The central idea is to provide the user with a multi-level view derived from a single-level secure object-oriented database. Hence the database operations performed on the multi-level views are decomposed into a set of operations on the single-level...

At ISPEC ’12, Samelin et al. show that the redactable signature scheme introduced at VLDB ’08 by Kundu and Bertino does not always preserve the structural integrity of the tree signed. In particular, they show how redaction of non-leaves promotes descendants and allows a third party to add new edges to the signed tree. This alters the semantic meaning of the tree and is not acceptable in certai...

The bacterium Coxiella burnetii has been associated with reproduction disorders in dairy cattle. A cross-sectional study was conducted Quebec, Canada, to estimate the prevalence of C. cows from RT-PCR-positive and/or ELISA-positive herds. As a secondary objective, associations between burnetii-positivity and three reproductive outcomes (purulent vaginal discharge, cytological endometritis, succ...
