OBJECTIVES 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 iso...
background : echinococcosis or hydatidosis is a chronic, zoonotic worldwide infection caused by the larval stage of the dog taeniid tapeworm echinococcus granulosus. vaccination has been considered as one of the ways to prevent of hy-datidosis in recent decades. the aim of this study was to construct a pcdna3.1 eukaryotic expression vector contain-ing the subunit 8-kda antigen b (hyd1) of e. gr...
genetic typing methods of t. gondii strains have been extensively perfected in recent years. from a technical point of view, many tools usable for genetic studied on single-copy loci have been used: rflp, pcr-rflp, sequencing, rapd-pcr and isoenzyme analysis. we described the cloning and sequence analysis of the gene which encodes the major surface antigen (sag1 or p30) of t. gondii. sag1 is th...
A total of 231 serum samples were collected from sheep (n=9), goats (n=99) and cattle (n=123) in northeastern KwaZulu-Natal, South Africa. Trypanosome infection was detected using Trypanosoma brucei brucei crude antigen (TbbCA) and T. congolense crude antigen (TcoCA) ELISA assays. Recombinant antigen (T. evansi GM6 which consisted of 4 repeat domains, TeGM6-4r) ELISA and immunochromatographic t...
Background: Transient and stable transformation of host plants are the common techniques to produce transgenic plants. However, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. While, transient gene expression is a quick method to produce recombinant proteins in plants. Objective: The main goal of the present study was to eva...
Abstract Background: Removal of prostate and radiotherapy are used routinely for treatment of prostate cancer however in advanced stages of the disease these treatments are ineffective. Researchers are exploring strategies for preventing this malignancy. This study aims to design and develop a phage based vaccine for preventing prostate cancer. Materials and methods: After conducting bioinforma...
Adaptive immunity in jawless vertebrates (lamprey and hagfish) is mediated by lymphocytes that undergo combinatorial assembly of leucine-rich repeat (LRR) gene segments to create a diverse repertoire of variable lymphocyte receptor (VLR) genes. Immunization with particulate antigens induces VLR-B-bearing lymphocytes to secrete antigen-specific VLR-B antibodies. Here, we describe the production ...
Cryptosporidium is an important cause of diarrhea in developed and developing countries, and its epidemiology is of interest. The methodologies used in the detection of Cryptosporidium-specific antibodies vary widely, which complicates comparison of results. This study assesses the performance of a Cryptosporidium recombinant protein (rCP41) in a serological assay compared to that of a crude an...
Rapid production of influenza vaccine antigen is an important challenge when a new pandemic occurs. Production of recombinant antigens in plants is a quick, cost effective and up scalable new strategy for influenza vaccine production. In this study, we have characterized a recombinant influenza haemagglutinin antigen (HAC1) that was derived from the 2009 pandemic H1N1 (pdmH1N1) virus and expres...
