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 and purpose: The purpose of this study was to design a recombinant vector pEFGP- N1 containing the full length of HIV-1Vpr gene. To the best of our knowledge, the cloning of Vpr gene in pEGFP_N1 is not previously done. Materials and methods: As a source of Vpr gene the pUC19-Vpr recombinant vector was confirmed by digestion with restriction enzymes BglII and NotI in order to separ...
Abstract Background and Objectives: Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease. Mucosal feeding of myelin basic protein binding to the cholera toxin B subunit can reduce the intensity of the immune response in MS patients. Expression system, the domain composition of the fusion protein, accessibility of two domains, codon adaptation index (CAI) and GC contents are v...
BACKGROUND Neosporosis is caused by an obligate intracellular parasitic protozoa Neospora caninum which infect variety of hosts. NcSRS2 is an immuno-dominant antigen of N. caninum which is considered as one of the most promising targets for a recombinant or DNA vaccine against neosporosis. As no study has been carried out to identify the molecular structure of N. caninum in Iran, as first step,...

Abstract Background and Objectives In Iran, Khorasan province is an endemic area for HTLV-1 virus. Considering the inability of serological tests to determine HTLV-1 in window period, their failure to confirm the indetermination results of western blot, and given the probability for HTLV-1 transfusion transmission, a SYBR green-based Real Time PCR was set to measure the HTLV-1 proviral load. ...
Objective(s):Brucellosis is a well-known domestic animal infectious disease, which is caused by Brucella bacterium. GroEL antigen increases Brucella survival and is one of the major antigens that stimulates the immune system. Hence, the objective of the present study was cloning and bioinformatics analysis of GroEL gene. Materials and Methods: The full-length open reading frame of this gene was...
BACKGROUND Due to the limitations of the classical methods to detect Coxiella burnetii, direct diagnosis of the pathogen using PCR techniques is still the preferable approach. However, false negative results owing to the presence of PCR inhibitors are troublesome. OBJECTIVES In order to identify the inhibitors during PCR assay, an internal positive control (IPC) was designed based on 16SrRNA ...

BACKGROUND Adhesion protein E (PE) of Haemophilus influenzae is a 16 - 18 kDa protein with 160 amino acids which causes adhesion to epithelial cells and acts as a major factor in pathogenesis. OBJECTIVES In this study, we performed cloning, expression and purification of PE as a candidate antigen for vaccine design upon further study. MATERIALS AND METHODS At first, the pe gene of NTHi ATCC...
