background toxoplasma gondii is an obligatory intracellular protozoan parasite, which infects human beings. since the current antigens used for diagnosis or vaccination are contaminated with non parasitic material in which the parasite is grown, it is tried to produce recombinant antigens to design vaccines against toxoplasmosis, or make diagnostic kits. choosing the type of antigen to produce ...
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...
Restricted antibody reactivity to hepatitis C virus (HCV) synthetic peptides has been observed in HCV-infected patients on haemodialysis (HD). The aim of this study was to evaluate third-generation anti-HCV enzyme-linked immunosorbent assay (ELISA) test systems containing either synthetic peptide HCV antigens or recombinant HCV antigens or a combination of synthetic and recombinant antigens in ...
The lambda gt 11 expression vector permitted us to survey protein antigens of Mycobacterium leprae and Mycobacterium tuberculosis expressed in Escherichia coli. Using monoclonal antibodies, recombinant clones were detected producing three major antigens of M. tuberculosis and five major protein antigens of M. leprae. These recombinant antigens produced in E. coli should prove useful for diagnos...
background and objectives: hbha and mtb32c have been isolated from culture supernatants of mycobacterium tu- berculosis (m. tuberculosis) and mycobacterium bovis (m. bovis) and their immunogenicity previously studies have been confirmed. in this study, capability of constructed vector containing two mycobacterial immunodaminant antigens (mt- b32c-hbha), in producing new chimeric protein under t...
A Mycobacterium leprae expression library was constructed in the vectors EX1, pEX2, and pEX3 and screened with a pool of 19 well-absorbed sera from household contacts of leprosy patients. Twelve selected recombinants that were further characterized differed clearly from recombinants selected with murine monoclonal antibodies. Whereas the monoclonal antibodies recognized mainly six recombinant a...
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: Hepatitis B is an important infectious disease. Since several years ago, mass vaccination against this viral infection has become as part of routine vaccination schedule of Iran. However, some healthy neonates, children and adults fail to generate a protective antibody response after vaccination.Objectives: To investigate distribution of HLA class-I and class-II antigens in health...
Naturally occurring antibody responses to Plasmodium falciparum rhoptry-associated proteins 1 and 2 (RAP-1 and RAP-2) were measured with recombinant and parasite-derived forms of the antigens. For comparative purposes, responses to multiple forms of three other malarial antigens were also examined. The sera of 100 Papua New Guineans were screened for antibodies. Eighty-six and 82% of individual...
