Abstract

Abstract Background and Objectives: Diarrhea is one of the most common diseases in the world. Campylobacter jejuni is one of the prevalent agents of bacterial diarrhea in most of developing countries. It is usually ignored in routine laboratory test in our country, because it has a difficult investigation method. This article aims to determine the prevalence of Campylobacter jejuni, in diarrhea samples in Gorgan City (East north of Iran) by PCR Method. Material and Methods: This descriptive study was performed on 455 diarrheal samples during one year (2005-06).255 out of them were cultured on Preston media (Himedia co.) on 42°c. DNA Extracted by phenol cholorophorm method was directly carried out on stool samples.16srDNA hipo and asp primers for detection of Campylobacter genus, C.jejuni and C.coli species were used, respectively. In addition, universal primer of 16srDNA was used for control of PCR method. Results: no sample was positive for Campylobacter in culture .only three samples were positive for Campylobacter genus and C.jejuni specific primer but none of them were positive for C.coli .99 samples were positive by universal primer of 16srDNA . Conclusion: The results indicate that C.jejuni isn't a prevalent agent in diarrhea in our region. Key words: Campylobacter jejuni -Gorgan- Diarrhea

Abstract

Abstract Background and Objective: One of the proteins shared in all strains of Brucella is 31 kDa surface protein (BCPS31) that could be an appropriate target for immunization and serological diagnosis. Material and Methods: In the present study, BCSP31 produced as a recombinant protein in pET28a (+) expression system was utilized, using ELISA, to detect trace specific antibody (IgG) in brucellosis patients' serum that was confirmed by culture. We also evaluated cytokine response of peripheral blood lymphocytes to this protein in the cell culture. Results: The results indicated a significant amount of surface protein antibodies (IgG) in the serum of patients with brucellosis. Evaluation of lymphocyte responses to rBCSP31 also showed a significant IL-12 and IFN-γ production in patients’ lymphocyte cultures. Conclusion: These results suggest that BCSP31 can elicit specific humoral and cellular responses during host infection and it can be used in designing immunization and serologic diagnosis systems. Keywords: Brucellosis, 31kDa Cell Surface Protein, Brucella, Cytokine
