Background and Aims: Varicella-zoster virus (VZV) infection among pregnant women can cause a serious threat to the health of mother and fetus. Varicella is clearly less dangerous for immunized mothers. The aim of this study was to determine the prevalence of VZV antibody among women before marriage.
Materials and Methods: This cross-sectional study was conducted on 300 women of child-bearing age who referred to Yazd clinic for premarital screening. The enzyme-linked immunosorbent assay (ELISA) technique was performed to detect antibodies against VZV. Demographic characteristics of each participant, including age, educational level, place of residence, family and self-reported history of chickenpox were collected by a questionnaire. Results: Mean age of women under study was 23±5.4 years that 223 participants (73.7%) were seropositive, and 77 cases (25.7%) were seronegative for anti-VZV antibody, while 2 (0.6%) subjects had an equivocal result. A higher immunity ratio (86.4%) was found among older women (33-44 years). Data showed no significant correlation between immunity to VZV and age, educational level, place of residence. A statistically significant association was found between the family history, self-reported history of chickenpox and immunity to VZV. The positive and negative predictive values for self-reported history of chicken pox were 97.1% and 81.1%, respectively.
Conclusions: A significant number of women before marriage had no immunity to VZV. They are in risk of getting varicella, which can cause serious complications in mother and fetus. It, therefore, seems necessary to screen women of child-bearing age for anti-VZV antibody. In addition, vaccination against VZV in Iranian women before marriage can be a good recommendation.

Background and Aims: Hepatitis E virus is a public health concern and about a third of people in the world live in endemic areas. Although HEV is believed to be transmitted by fecal-oral routes between humans in low sanitary conditions, but evidence of transmission have been reported in hemodialysis (HD) patients.
Materials and Methods: Aim of present study was to determine the prevalence of anti-HEV antibody among HD patients in Gorgan, north of Iran. In this cross-sectional study, totally 300 HD patients from May to December 2014 were tested for detection of anti-HEV IgG and IgM by commercial HEV enzyme-linked immunosorbent assay (ELISA) kit. Demographic variables were collected in pre-designed questionnaires.
Results: Out of 300 individuals, 148 (49.3%) were male and 152 (50.7%) were female. The overall anti-HEV IgG seroprevalence rate was 4%. Result showed significant association between anti-HEV IgG and duration of dialysis (p = 0.03), but there were no significant differences between the subjects grouped according to gender, Ethnicity, dialysis per week and age. No anti-HEV IgM were detected in patients.
Conclusions: Since our finding showed statically significant relationship between duration of hemodialysis and anti-HEV. Therefore, hemodialysis maybe be considered as a risk factor in HEV transmission. However further studies are needed to confirm our data.

Background and Aims: Different hepatitis C virus (HCV) genotypes have characteristic geographical distribution. Identification of HCV genotype is an important factor in the progression, clinical outcome and therapy of HCV infection. The aim of this study was to determine the prevalence of HCV genotypes among HCV-RNA positive patients in Yazd, Iran.
Materials and Methods: In this cross-sectional study, 150 HCV-infected individuals with detectable plasma HCV RNA levels were enrolled from January to August 2015. HCV-RNA was extracted from plasma samples and retro-transcribed to c-DNA. Then HCV genotypes 1, 2, 3a, 4 were determined using a PCR based genotyping kit.
Results: A total of 150 HCV-positive patients with mean age 40.45±11.83 were enrolled in the study. 89.3% of participant were males and 10.7% were females. The most common genotype was 3a (52%), followed by 1a (28%). Mixed-genotype infection was 20% and the most prevalent mixed genotype was 3a/1a (83% of mixed genotypes). The other genotypes were 1a/1b/3a in 10%, 3a/2 and 1a/2/3a both in 3% of patients with mixed HCV genotypes.
Conclusions: Unlike other regions of Iran, Genotypes 3a was predominant in HCV-RNA positive patients in Yazd province. Also, HCV mixed-genotype infections are more common than previously estimated in other studies from different parts of the country.

Background and Aims: Human lymphotropic virus type-1 (HTLV-1) causes various diseases such as adult T-cell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy/tropical spastic paraperesis (HAM / TSP) in humans. The main goal of this study is to compare Iranian protease subtypes structure of this virus (HTLV-1) to samples collected from other part of world in order to understand their differences.
Materials and Methods: During 1394 -1395, 10 blood samples taken from HTLV-1 virus infected individuals. Samples went through polymerase chain reaction (PCR) process.The obtained products were sequenced and phylogenetic analysis were done. The second and third structures of these sequences were obtained by using a specialized websites.
Results: The Iranian samples were completely exposed in to the cluster of Cosmopolitan subtype. The result of first structure alignment of protease protein in different subtypes of the virus, suggested some differences in the gene of interest. The conversion of the first structure to second and third structures and respectively pairwise and multiple alignment showed no significant difference in the protease protein conformation.
Conclusions: The comparison of HTLV-1 virus protease protein from Iran and other sequences in the world which were obtained from GenBank shows no significant dissimilarity. This dissimilarity help to design the production of the drug. Therefore, future studies can be targeting a part of the protein and generalize the treatment outcomes to all subtypes circulating. This comparison have beneficiary effect in making the right medication that inhibit the subtypes of the virus in treatment studies of disease developed by this virus.

Background and Aims: Hepatocellular carcinoma (HCC) is one of the most important common cancers in the world. The main etiology of this cancer in developing and third world countries is due to the infection with hepatitis B and C viruses. Hepatitis B and C viruses (HCV) would both cause liver cancer but the incidence of the disease in relation to the age and gender has not been determined. The present study was conducted to evaluate the relation between some demographic characteristics with rs1053004 polymorphism in STAT3 gene among patients with liver cancer following chronic hepatitis B infection and its comparison with healthy subjects.
Materials and Methods: In this study, 33 tissue samples of liver cancer from pationts with HBV infection, 50 blood samples from patients with chronic hepatitis B and 50 blood samples from healthy subjects, as the control group, were obtained to determine rs1053004 polymorphism in STAT3 gene (signal transducer factor and activator of transcription in the nucleus) using Real Time PCR method.
Results: In the present study 133 subject were evaluated and from them, 50 (37.6%) were healthy and 50 of the participants (37.6%) had chronic hepatitis B and 33 (24.8%) had HCC. 69.9% of the participants (93 participants) were male and 30.1% (40 participants) were female. According to the results, the gender of the participants in the studied groups had no significant relation with their SNPrs1053004 polymorphism. But the relation between gender and liver cancer was statistically significant (p < 0001); indicating that the prevalence of liver cancer was higher among men than women. The average age of the healthy group was 35.86 years, of the chronic hepatitis B group was 40.4 years and of the HCC group was 53.78 years. Based on the results, the difference in age groups of chronic hepatitis B group and HCC pationts was statistically significant as compared with the control group (p < 0.001).
Conclusions: Results of the present study showed no significant relation between the presence of rs1053004 polymorphism in STAT3 gene (signal transducer factor and activator of transcription in the nucleus) and gender of the participants but the difference between the ages of the healthy group, chronic hepatitis B group and HCC group was statistically significant. In other words, age could be a predicting factor in developing HCC

Background and Aims: Sistan is a major pole in dairy production and genetic resource for the unique sistanian breed in the southeast of Iran. This region has a wide border with Afghanistan and cattle imports are done through this border. The main aim of this study was to compare the seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection rate using direct Enzyme-linked immunosorbent assay (ELISA) test among imported and native cattle’s.
Materials and Methods: Totally, 180 serum samples were collected from 20 non-vaccinating farms in the north of Sistan and Baluchistan province –Iran. Commercial indirect ELISA test was used for detection of serum antibodies against BVDV. Statistical analysis was performed using Chi-square test.
Results: The number of 123 (68.33%) cows were seropositive. All of the herds were were ELISA seropositive. The seroprevalence ranged from 73 to 100 percent within the farms. The prevalence was significantly higher in cows higher than 2 years old compared to animals lower than 2 years old (P<0.05).The results revealed no significant differences in seroprevalence of BVDV between native Iranian and imported cattle in Sistan. Sex of animal had no influence on the prevalence of BVDV.
Conclusions: Results of this study indicated that BVDV was highly prevalent in the north of Sistan and Baluchistan and BVDV infection could be controlled by livestock – trade control, and considering biosecurity measures in farms.

Newcastle disease (ND) is a highly contagious disease that affects many species of birds and causes significant economic losses to the poultry industry worldwide and the pathogenicity of Newcastle disease virus (NDV) strains varies with different virulence. Samples were collected from chicken commercial farms in Iran during 2014–2015. ND virus were characterized (NDV) by partial sequences of fusion genome and compared with other NDV sequences. All viruses showed the amino acid sequence 112 RRQKRF117 at the C-terminus of the F2 protein and phenylalanine at the N-terminus of the F1 protein, residue 117. These amino acid sequences were identical to a known virulent motif. Based on the phylogenetic analysis the Iranian ND isolates are closely related to the genotype VIId of class II NDV strains. The result show that the genotype VIId is dominant and circulating among chicken farms and cause clinical disease.
