background: dense granules are immunodominant proteins for the standardi-zation of immunodiagnostic procedures to detect neosporosis. in the presented study different fragment of a dense-granule protein was evaluated for serodiagno-sis of neospora caninum in cattle and water buffalo. methods: ncgra7, from n. caninum tachyzoites was amplified. pcr product and pmal-c2x plasmid were digested with ...
Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...
Introduction:Toxoplasma gondii is a ubiquitous obligate intracellular parasite with a relatively broad host range infecting both mammals and birds. Toxoplasma proteins are strong antigens that can begin strong immune reactions, among which Rhoptry protein 1 (ROP1) can be named discharging from rhoptry cell-organ. ROP1 is regarded as a competitor for recombinant vaccines against toxoplasmosis. T...
Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...
results based on our results, mab against recombinant erns was produced and reacted successfully with recombinant and natural antigens. conclusions with regards to the role of erns in the identification of pi animals, it appears that erns recombinant antigen and the specific monoclonal antibodies produced against it may be suitable for developing bvdv laboratory diagnostic assays. objectives er...
background: filamentous hemagglutinin (fha) is one of the most important immunoprotective antigens of bordetella pertussis (b.pertussis) and a major component of the acellular pertussis vaccine. in the present study, three overlapping recombinant fragments from the immunodominant region of fha were produced and their immunogenicity was investigated. methods: three overlapping coding sequences o...
Background: The advent of recombinant DNA technology has facilitated heterologous expression of proteins from various sources in different host systems including Escherichia coli. If a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. Such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...
background: the assays currently available for the detection of specific anti- toxoplasma antibodies may vary in their abilities to detect serum immunoglobulins, due to the lack of a purified standardized antigen. the aim of this study was evaluation the recombinant toxoplasma gondii sag1 antigen for the serodiagnosis of acute and chronic toxoplasmosis. methods : this study describes an elisa u...
Background: Although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. Objective: The aim of this study was to clone the first 1100 bp of the C. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...
Background & Aims: Toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. The parasite is able to infect all warm-blooded hosts including humans and farm animals. The infection in humans often occurs after the ingestion of raw or undercooked meat containing tissue cysts. Several methods have been applied to detect this parasite in contaminated foods. Reco...
