Abstract Background and objectives: HTLV-1 virus belongs to the retrovirus and infection with this virus mostly is seen among people having more than one time blood transfusion. Because of requiring repeated blood transfusions, thalassemic patients are considered to be high risk subjects in this regard. Thus, this study was carried out to indicate the frequency of HTLV-1 infection among the thalassemic patients. Materials and Methods: Blood samples of 181 thalassemic patients referred to Taleghani hospital during nearly two years (2004-2005) were taken. By using ELISA technique, the sera were assessed to determine HTLV antibody. The positive ones subsequently were examined by western Blot (kit, 2.4) to confirm the ELISA positive samples and also to recognize the HTLV type. Results: Of 181 thalassemic patients, 93 (51.4%) were male. The age was between one and twenty five (14.11 ± 6.5). 93.4% (169) were received packed cell only once in a month. 14.9% (27) were HTLV positive by ELISA technique, while just eight out of these 27 were considered to be true positive by Western blot and to be contaminated by type one virus. Of all subjects, 4.4% were positive HTLV1. Furthermore, the contamination with this virus is increased as the patients getting older. Conclusion: The findings indicated that among the thalassemic patients in Gorgan, there are cases with HTLV-1 whose frequency is correlated with the other part of our country. Consequently, further comprehensive studies are required to identify those infected blood donated to minimize the transmission risk of this infection in the society and in particular among the people receiving blood, such as thalassemic patients.

Abstract Background and objectives: Herpes simplex virus type two (HSV-2) infections are mostly considered as a sexually transmitted disease. It causes genital herpes, newborn herpes non-pyrogenic meningitis and may act as an underlying factor for HIV infection. This study was conducted to determine the sero-epidemiologic prevalence of herpes simplex virus type two in cases referred to ten clinical laboratories of Gorgan. Materials and methods: This cross- sectional study was performed on blood Samples of 406 randomly selected Clients. These samples were analyzed for Anti HSV-2 using Specific enzyme-Linked immunoassays (ELIZA) Results: Four point nine percent of all subjects have anti HSV-2. There is Significant difference between sero-positive HSV-2 and factors such as age and Marital Status (P<0.05). Conclusion: HIV is progressively increased and HSV-2 infection is one of the major risk factors for HIV therefore, decreasing the prevalence of HSV-2 infections may Leads to the reduction of HIV prevalence.

Abstract Backgrounds and objectives: Herpes simplex virus type 1 (HSV- 1) infections are mostly shown as a Herpes disease, but It causes conjunctivitis, genital herpes, encephalitis and newborn herpes. This study was conducted to determine the sero-epidemiologic prevalence of herpes simplex virus type 1 in cases referred to clinical laboratories of Gorgan, Iran. Material and methods: In this cross sectional study, we did random blood sampling on 406 cases referred to the Gorgan city's clinical laboratories. These samples were analyzed for HSV-1 Immunoglobulin G and M antibodies using type- specific enzymelinked Immunoassays (ELISA). Results: Of 406 participants, the HSV-1 seroprevalence is 49% (44.3% and 4.7% for IgG and IgM respectively). There is not significant relationship between seropositive HSV-1 and gender, ethnicity, age and marital status. Conclusion: Sero-epidemiological of HSV-1 in Gorgan is the same of the other places in Iran, but it is higher than European and lower than African countries. It seems that the people’s culture is very important. Therefore it needs to be investigated more. Keywords: HSV-1, Antibody, Gorgan.

Abstract Background and objectives: Infection has a Leading role in pregnancy. Cytomegalovirus (CMV), listeria and Toxoplasma are the most common causes of infection in human. Based on the previous researches, about 15-25 percent of being infected during pregnancy leads to some complications such as abortion, fetal death, early labor and etc. This study was designed to determine the seroprevalence of Cytomegalovirus (CMV), Toxoplasma gondii and Listeria moncytogenes among pregnant women in Gorgan, north of Iran (2005-2006). Material and Methods: we conducted this Simple randomized study on 118 unsuccessful pregnant woman and 99 successful ones referred to Deziani hospital in Gorgan. We assayed both IgG and IgM antibodies for CMV and Toxo by Elisa and IFA method for Listeria. In addition, we fill out a Check list and then use SPSS soft ware, chi square to analyze the data. Results: The frequency of IgG for CMV and Toxo is 89.9% and 45.5% in successful pregnant women and 77.1% and 44.1% for unsuccessful pregnant women (P=0.41, P=0.01). IgM frequency for CMV and Toxo is 14.1% and 46.5% in successful women and 30.5 and 21.7% in unsuccessful ones. (P=0.003, P=0.002)Total frequency (IgG, IgM) for Listeria is 7.62% and %3.03 in successful and unsuccessful women, respectively. There is a significant relation between abortion and IgM titer against Toxoplasma in successful and unsuccessful groups. (P=0.003).This relation is true for total antibody titer against Listeria (P=0.003). Conclusion: Because of high titer of antibodies against CMV, Toxo and Listeria in unsuccessful pregnant women, suffering from these agents during pregnancy may result in abortion and fetal death. Hence, we recommend to hold some preventive and educational program and also to assay antibodies against theses agents.

Abstract Background and Objective: Microsporidia is an obligatory intracellular parasite known as an opportunistic infection in immunocompromised patients. Its laboratory diagnosis is relatively difficult and modified trichrome staining is a standard diagnostic method for detection of Microsporidia. The aim of present study was to identify intestinal Microsporidia in kidney- transplanted patients, using modified Trichrome Staining and Calcofluor White Methods. Material and Methods: In 2012, 180 stool specimens were taken from kidney transplanted- patients given immunosuppressive drugs in Hamadan, Iran. To identify Microsporidia we use modified Trichrome Staining and Calcofluor White Methods. Results: The mean duration of kidney transplant and immunosuppressive drug using was 5.5 Years. Only one female patient was positive for Microsporidia. Conclusions: Owing to low frequency of this opportunistic infection among kidney transplanted patients, we can conclude that their hygienic conditions are good enough and they are not exposed with the parasites.

Abstract Background and Objective: Klebsiella pneumoniae is one of the agents causing nosocomial infection therefore, we decided to report the prevalence of Klebsiella pneumoniae caused infection. Material and methods: The frequency of Klebsiella in culture media samples of Panje Azar hospital was studied in 2011-2012. After determination of the species with biochemical methods and determination of resistance to third generation cephalosporins, the existence of responsible genes for this resistance was investigated using specific primers. The PCR product for CTX-M gene was sequenced. Results: During the study, 70 isolates of Klebsiella were isolated in that 51 (72.8%) related to three months of November, December and January. Except for the one related to November, other ESBL cases belonged to these three months. Based on molecular investigation of ESBL genes, these isolates at least were in 3 types and had a high frequency in Internal, female and Emergency wards. Conclusion: The present report implied a sudden prevalence of Klebsiella pneumoniae that detected and controlled by a correct monitoring. Keyword: Klebsiella Pneumoniae, ESBL, CTX-M
