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 objectives: After respiratory infection, Diarrhea is the second cause of mortality. Yersinia enterocolitica is the second important cause of infectious diarrhea in children of some countries. In this study, we evaluated the frequency of Yersinia entocolitica of diarrheal specimens in Gorgan, Iran. Material and Methods: This descriptive cross - sectional Study was carried out on diarrheal stools of 455 patients referred to medical centers and laboratory of Gorgan in 2004-2005. DNA extraction using phenol chloroform was performed for all samples. Using two specific primers (genus-specific16s rRNA and ail- specific species genus of Yersinia enterocolitica), we did PCR sample. Results: Yersinia genome was identified in 12 patients(2.63%) and 11 of them was Yersinia enterocolitica. The frequency infection in of girls (3%) was more than boys (2.4%), and the prevalence in winter (4%) was more them other seasons, and under one- year- group (3.4%) and 1-5 years (3.1%) is more than other age groups. It was not observed significant difference. (P> 0.05). Conclusion: The frequency of Yersinia in cases of diarrhea in Gorgan is similar to most regions of Iran and in children under 5 years is observed more in winter.

Abstract
Abstract Background and objectives: Recurrent Abdominal Pain (RAP) syndrome is a common disorder, especially in children with beta thalassemia major. These patients are predisposed to heart diseases which are caused by hemochromatosis (Iron overload), resulting in sudden death. Because of the role of Helico bacter pylori in causing abdominal pain and peptic ulcer, and in increasing the risk or exacerbating of heart diseases, it can be important in beta thalassemia major. This study aimed at determining the frequency of anti- H.pylori class IgA in patients suffered from beta thalassemia major. Material and Methods: In this descriptive-analytic Study, 132 beta thalassemia major Patients and 135 healthy cases were matched by age, sex and ethnic as a control group. The sera were separated from clot in first Seroepidemiology and along with the filled questionnaires sent to Immunology-hematology Laboratory of paramedical school, in which the samples were tested by ELISA method with Diagnostic kit for anti-H.pylori IgA and IgG classes detection. We analyzed the Data by chi square and Independent T and Fisher tests. Results: the results show that the difference between the anti-H.pylori class IgA in case (22.7%) and control group (17.8%) is not significant (P=0.6), But it is significant between anti-H.pylori IgG class, 81.8% for cases and 54.8% for controls (P<0.001). Conclusion: Based on the results, the rate of anti-H.P IgA class in case is 1.131 times more than control group, which is not significant. On the other hand , the rate of anti-H.P IgG is 1.478 times more than control group which is significant. Key words: Thalassemia, Helicobacter pylori, Gorgan, Sero epidemiology.
