Abstract
Objectives Tuberculosis (TB), a contagious disease caused by Mycobacterium tuberculosis (M. tuberculosis), remains a health problem worldwide and this infection has the highest mortality rate among bacterial infections. Current studies suggest that intranasal administration of new TB vaccines could enhance the immunogenicity of M. tuberculosis antigens. Hence, we aim to evaluate the protective efficacy and immunogenicity of HspX/EsxS fusion protein of M. tuberculosis along with ISCOMATRIX and PLUSCOM nano-adjuvants and MPLA through intranasal administration in a mice model. Materials and Methods In the present study, the recombinant fusion protein was expressed in Escherichia coli and purified and used to prepare different nanoparticle formulations in combination with ISCOMATRIX and PLUSCOM nano-adjuvants and MPLA. Mice were intranasally vaccinated with each formulation three times at an interval of 2 weeks. Three weeks after the final vaccination, IFN-γ, IL-4. IL-17, and TGF-β concentrations in the supernatant of cultured splenocytes of vaccinated mice as well as serum titers of IgG1 and IgG2a and sIgA titers in nasal lavage were determined. Results According to obtained results, intranasally vaccinated mice with formulations containing ISCOMATRIX and PLUSCOM nano-adjuvants and MPLA could effectively induce IFN-γ and sIgA responses. Moreover, both HspX/EsxS/ISCOMATRIX/MPLA and HspX/EsxS/PLUSCOM/MPLA and their BCG booster formulation could strongly stimulate the immune system and enhance the immunogenicity of M. tuberculosis antigens. Conclusion The results demonstrate the potential of HspX/EsxS-fused protein in combination with ISCOMATRIX, PLUSCOM, and MPLA after nasal administration in enhancing the immune response against M. tuberculosis antigens. Both nanoparticles were good adjuvants in order to promote the immunogenicity of TB-fused antigens. So, nasal immunization with these formulations, could induce immune responses and be considered a new TB vaccine or a BCG booster.

Abstract
Aim: This study aimed to investigate the role of AmpC enzymes in carbapenem resistance among AmpC/extended-spectrum β-lactamase (ESBL)-producing clinical isolates of Escherichia coli and Klebsiella spp. Methods: Fifty-six bacterial strains that were AmpC producers were examined. The antibiotic susceptibility test was performed by the disk diffusion and E-test. The prevalence of the plasmid carbapenemase was determined using PCR. Results: The resistance to meropenem in the AmpC+/ESBL+ group was 64%, higher than that reported for the AmpC-/ESBL+ group. Ten isolates of the carbapenem-resistant AmpC producers were negative for carbapenemase-encoding genes. Conclusion: Carbapenem resistance among AmpC-producing isolates with negative results for carbapenemase-encoding genes potentially demonstrates the role of AmpC enzymes among these isolates.

Abstract
Metal phosphides, especially aluminum phosphide, and phosphine (PH3 ) are widely used as insecticides and rodenticides for protection of grains during process of storage and transportation. The main reason of poisoning with this compound is related to the conscious ingestion of salts or accidental inhalation of PH3 . So the early and accurate diagnosis of poisoning can significantly help to the effective clinical treatment or recognition of death cause. PH3 is somewhat unstable due to reaction with oxygen or hemoglobin leading to formation of oxy-acids phosphorous. Here, we critically reviewed the literature introducing the quantitative and qualitative methods for the detection of metal phosphides, PH3 , and its products. This study obviously demonstrates that during past years, different diagnosis methods have been remarkably progressed. Head-space gas chromatography and confirmatory colorimetric methods have been as the most popular techniques. Also, the gas sensors are a promising method that must be more progressed.

Abstract
Mycobacterium simiae is an emerging and spreading pathogen in Iran and little data about its drug susceptibility test (DST) and no standard treatment regimen are available. We report a case of multidrug-resistant M. simiae respiratory infection in a 65-year-old woman with a history of previous Mycobacterium tuberculosis infection. The patient was treated with clarithromycin, levofloxacin, and cotrimoxazole for one year and eventually died while still suffering from respiratory problems. For DST, broth microdilution method was used according to the Clinical and Laboratory Standards Institute guidelines as well as molecular DST in clinical isolate. Mycobacterium simiae was resistant to streptomycin, moxifloxacin, clarithromycin, and cotrimoxazole antibiotics and was sensitive to clofazimine and amikacin antibiotics. Inappropriate use of antibiotics without determining the pattern of antibiotic resistance increases the likelihood of resistance and, for resistant specimens, the need to review the treatment protocol and replace antibiotics. Effectiveness based on antibiotic resistance pattern is essential.

Abstract
Incidence of Mycobacterium simiae pulmonary infection is increasing and diagnosis and treatment are challenging. We surveyed the clinical features, risk factors, diagnosis, and management in 20 patients from northeastern Iran diagnosed by line probe assay and confirmed by sequencing the ITS (16S-23S) rRNA region and carried out a literature review using the keywords "pulmonary infection" and "Mycobacterium simiae." The mean age of patients was 55.1 years, with 80% female and 90% diagnosed by sputum. Clinical symptoms included severe cough (90%), sputum production (70%), haemoptysis (50%), and chest pain (35%). Comorbidities included a history of tuberculosis (60%), smoking (40%), or chronic obstructive pulmonary disease (20%). Patients were treated with levofloxacin, clarithromycin, and co-trimoxazole. Except for two patients, the clinical symptoms improved. Mycobacterium simiae pulmonary infection is increasing in people with underlying diseases. Although choosing the most appropriate treatment remains a challenge, combining successful treatments could be useful in treating these patients.

Abstract
Mycobacterium tuberculosis is the causative agent of tuberculosis (TB), and pulmonary TB is the most prevalent form of the disease worldwide. One of the most concrete actions to ensure an effective TB control program is monitoring TB treatment outcomes, particularly duration to cure; but, there is no strong evidence in this respect. Thus, the primary aim of this study was to examine the possible spatial variations of duration to cure and its associated factors in Iran using the Bayesian spatial survival model. All new smear-positive PTB patients have diagnosed from March 2011 to March 2018 were included in the study. Out of 34,744 patients, 27,752 (79.90%) patients cured and 6992 (20.10%) cases were censored. For inferential purposes, the Markov chain Monte Carlo algorithms are applied in a Bayesian framework. According to the Bayesian estimates of the regression parameters in the proposed model, a Bayesian spatial log-logistic model, the variables gender (male vs. female, TR = 1.09), altitude (>750 m vs. ≤750 m, TR = 1.05), bacilli density in initial smear (3+ and 2+ vs. 1–9 Basil & 1+, TR = 1.09 and TR = 1.02, respectively), delayed diagnosis (>3 months vs. <1 month, TR = 1.02), nationality (Iranian vs. other, TR = 1.02), and location (urban vs. rural, TR = 1.02) had a significant influence on prolonging the duration to cure. Indeed, pretreatment weight (TR = 0.99) was substantially associated with shorter duration to cure. In summary, the spatial log-logistic model with convolution prior represented a better performance to analyze the duration to cure of PTB patients. Also, our results provide valuable information on critical determinants of duration to cure. Prolonged duration to cure was observed in provinces with low TB incidence and high average altitude as well. Accordingly, it is essential to pay a special attention to such provinces and monitor them carefully to reduce the duration to cure while maintaining a focus on high-risk provinces in terms of TB prevalence.

Abstract
Diabetic foot ulcers (DFUs) are chronic severe complications of diabetes disease and remain a worldwide clinical challenge with social and economic consequences. Diabetic wounds can cause infection, amputation of lower extremities, and even death. Several factors including impaired angiogenesis, vascular insufficiency, and bacterial infections result in a delayed process of wound healing in diabetic patients. Treatment of wound infections using traditional antibiotics has become a critical status. Thus, finding new therapeutic strategies to manage diabetic wounds is urgently needed. Nanotechnology has emerged as an efficient approach for this purpose. This review aimed to summarize recent advances using nanotechnology for the treatment of diabetic wounds.

Abstract
Tuberculosis (TB) is referred to as a "consumption" or phthisis, which has been a fatal human disease for thousands of years. Mycobacterium tuberculosis (M. tb) might have been responsible for the death of more humans than any other bacterial pathogens. Therefore, the rapid diagnosis of this bacterial infection plays a pivotal role in the timely and appropriate treatment of the patients, as well as the prevention of disease spread. More than 98% of TB cases are reported in developing countries, and due to the lack of well-equipped and specialized diagnostic laboratories, development of effective diagnostic methods based on biosensors is essential for this bacterium. In this review, original articles published in English were retrieved from multiple databases, such as PubMed, Scopus, Google Scholar, Science Direct, and Cochrane Library during January 2010-October 2019. In addition, the reference lists of the articles were also searched. Among 109 electronically searched citations, 42 articles met the inclusion criteria. The highest potential and wide usage of biosensors for the diagnosis of M. tb and its drug resistance belonged to DNA electrochemical biosensors (isoniazid and rifampin strains). Use of biosensors is expanding for the detection of resistant strains of anti-TB antibiotics with high sensitivity and accuracy, while the speed of these sensory methods is considered essential as well. Furthermore, the lowest limit of detection (0.9 fg/ml) from an electrochemical DNA biosensor was based on graphene-modified iron-oxide chitosan hybrid deposited on fluorine tin oxide for the MPT64 antigen target. According to the results, the most common methods used for M. tb detection include acid-fast staining, cultivation, and polymerase chain reaction (PCR). Although molecular techniques (e.g., PCR and real-time PCR) are rapid and sensitive, they require sophisticated laboratory and apparatuses, as well as skilled personnel and expertise in the commentary of the results. Biosensors are fast, valid, and cost-efficient diagnostic method, and the improvement of their quality is of paramount importance in resource-constrained settings.

Abstract
BACKGROUND The line probe assay (LPA) is one of the most accurate diagnostic tools for detection of different Mycobacterium species. Several commercial kits based on the LPA for detection of Mycobacterium species are currently available. Because of their high cost, especially for underdeveloped and developing countries, and the discrepancy of non-tuberculous mycobacteria (NTM) prevalence across geographic regions, it would be reasonable to consider the development of an in-house LPA. The aim of this study was to develop an LPA to detect and differentiate mycobacterial species and to evaluate the usefulness of PCR-LPA for direct application on clinical samples. METHODS One pair of biotinylated primers and 15 designed DNA oligonucleotide probes were used based on multiple aligned internal transcribed spacer (ITS) sequences. Specific binding of the PCR-amplified products to the probes immobilized on nitrocellulose membrane strips was evaluated by the hybridization method. Experiments were performed three times on separate days to evaluate the assay's repeatability. The PCR-LPA was evaluated directly on nine clinical samples and their cultivated isolates. RESULTS All 15 probes used in this study hybridized specifically to ITS sequences of the corresponding standard species. Results were reproducible for all the strains on different days. Mycobacterium species of the nine clinical specimens and their cultivated isolates were correctly identified by PCR-LPA and confirmed by sequencing. CONCLUSION In this study, we describe a PCR-LPA that is readily applicable in the clinical laboratory. The assay is fast, cost-effective, highly specific, and requires no radioactive materials.

Abstract
BACKGROUND Tuberculosis (TB) is the leading cause of death by infectious diseases worldwide, and especially prevalent in developing countries. Several vaccines against TB have been developed, recently. The aim of the present study was to design and construct a cloning vector encoding Mycobacterium tuberculosis (MTB) mpt51 gene. METHODS DNA was extracted from MTB H37Rv strain. Gene-specific primers were designed using Gene Runner software and the mpt51 gene was amplified by PCR. The amplified fragment and pcDNA3.1(+) cloning vector were both digested with restriction enzymes, the mpt51 fragment was ligated into the vector, and the Escherichia coli (E. coli) TOP10 strain were transformed by the recombinant plasmid. Positive clones were identified by colony PCR, restriction enzyme digestion, and DNA sequencing. RESULTS The mpt51 gene was successfully cloned into pcDNA3.1(+). A 6400 bp band for the pcDNA3.1(+)/mpt51 recombinant plasmid and a 926 bp band for mpt51 were observed by colony PCR, and restriction enzyme digestion on agarose gels. The DNA sequence was 100% homologous with the mpt51 fragment of H37Rv in GenBank. CONCLUSION In the current study, the mpt51 gene of MTB was correctly cloned into pcDNA3.1(+). The expression of this recombinant vector can be studied in eukaryotic cells. Moreover, it is possible to determine the efficacy of this vector as a DNA vaccine candidate, and to test its protective function compared to BCG in animal models in future.

Abstract
Autophagy provides an initial membranous platform for incoming hepatitis C virus (HCV) RNA translation and immune evasion. Once HCV replication is established, this infrastructure will be unnecessary for translation of HCV RNA progeny. So, the autophagy plays key role in the replication and immune pathogenesis of HCV virus. The aim of this study was to study the effect of autophagy induction in Huh7.5 cell on virus titer. The Huh7.5 cell was transfected with recombinant pcDNA-Beclin1. The autophagy induction was evaluated via microtubule associated protein 1 light chain 3 staining as autophagy formation marker using flow cytometry. The HCV (JFH1) was inoculated 12-h post-transfection. Next, to evaluate the viral load, viral RNA was extracted after 24 and 48 h and virus titer was calculated using real-time PCR. The result of the current study shows that the induction of autophagy before virus infection was able to enhance virus yield from 4 × 103 copies/mL to 1 × 104 copies/mL at 24-h post-infection, but reduced viral load after 48 h up to 6 × 103 copies/mL. The study of cross-talk between autophagy and HCV may bring new hope for human intervention and treatment of HCV. Also, it opens new avenue to improve virus cultivation in cell culture and understanding HCV and host cell responses. © 2018 IUBMB Life, 71(1):41-44, 2019.

Abstract
BACKGROUND Tuberculosis caused by Mycobacterium tuberculosis (M. tuberculosis), remains as one of the leading causes of deaths worldwide, with nearly two million death cases annually. BCG (Bacille Calmette-Guerin) continues to be the most widely used vaccine in the world, but the protective immunity differs in different parts of the world. Accordingly, new strategies including DNA vaccines are essentially needed. This study was aimed to design and construct a cloning vector containing mpt64 gene of M. tuberculosis. MATERIALS AND METHODS M. tuberculosis H37Rv was cultured on Lowenstein Jensen medium, and genomic DNA was extracted. The mpt64 gene was amplified by PCR using designed specific primers. After the digestion of mpt64 and pcDNA3.1 (+) by BamHI and EcoRI restriction enzymes, the mpt64 fragment was ligated into the digested vector using T4 DNA ligase enzyme. Then, the recombinant vector was transformed into competent Escherichia coli (E. coli) TOP10 strain. To confirm the colonies of transformed bacteria, antibiotic resistance, colony-PCR, restriction enzyme digestion and DNA sequencing were used. RESULTS To confirm the clones, colony-PCR using mpt64 specific primers was performed and the fragment of 718 bp was observed by gel electrophoresis. Clones were also verified by restriction enzyme digestion using BamHI and EcoRI restriction enzymes and the 718 bp fragment was observed. Furthermore, results of DNA sequencing showed 100% homology with the mpt64 fragment of H37Rv in GenBank. CONCLUSION In this study, the mpt64 fragment was successfully cloned in pcDNA3.1 (+) vector. This construct can be used in future studies as a DNA vaccine in animal models to induce immune system responses.

Abstract
BACKGROUND & OBJECTIVE Tuberculosis (TB) remains a major cause of death around the world. Bacillus Calmette Guérin (BCG) is the only vaccine used in TB prevention that has a protective effect in children, but its effectiveness declines in adults. Design and development of new vaccines is the most effective way against TB.The aim of this study was to design and construct a DNA vaccine encoding mtb32C and mpt51 fusion genes of Mycobacterium tuberculosis. METHODS First, mpt51 fragment was amplified by PCR method. The pcDNA3.1+/mtb32C plasmid was transformed into E. coli JM109 and then extracted. The mpt51 gene and pcDNA3.1+/mtb32C plasmid were both digested with EcoRI and BamHI restriction enzymes followed by ligation of mpt51 fragment into the digested vector. The recombinant plasmid containing mtb32C and mpt51 was subsequently transformed into competent E. coli TOP10 strain. The clones were confirmed by colony-PCR, restriction enzyme digestion and sequencing. RESULTS Using agarose gel electrophoresis, a 926 bp fragment corresponded to mpt51 was observed. Digestion of the vector pcDNa3.1+/mtb32C and mpt51 gene was confirmed by electrophoresis. Then, the pcDNA3.1+/mtb32C plasmid was extracted. Sequencing results confirmed the accuracy of the desired plasmid. CONCLUSION In this study, we constructed a cloning vector encoding mtb32C/mpt51 gene of M. tuberculosis. The eukaryotic expression of this vector can be confirmed in future studies. It can be considered as a DNA vaccine in animal models later. Successful cloning provides a basis for the development of new DNA vaccines against TB.

Abstract
BACKGROUND The purpose of this study was to clone, express, and purify a novel multidomain fusion protein of Micobacterium tuberculosis (Mtb) in a prokaryotic system. METHODS An hspX/esxS gene construct was synthesized and ligated into a pGH plasmid, E. coli TOP10 cells were transformed, and the vector was purified. The vector containing the construct and pET-21b (+) plasmid were digested with the same enzymes and the construct was ligated into pET-21b (+). The accuracy of cloning was confirmed by colony PCR and sequencing. E. coli BL21 cells were transformed with the pET-21b (+)/hspX/esxS expression vector and protein expression was evaluated. Finally, the expressed fusion protein was purified on a Ni-IDA column and verified by SDS-PAGE and western blotting. RESULTS The hspX/esxS gene construct was inserted into pET-21b (+) and recombinant protein expression was induced with IPTG in E. coli BL21 cells. Various concentrations of IPTG were tested to determine the optimum concentration for expression induction. The recombinant protein was expressed in insoluble inclusion bodies. Three molar guanidine HCl was used to solubilize the insoluble protein. CONCLUSION An HspX/EsxS Mtb fusion protein was expressed in E. coli and the recombinant protein was purified. After immunological analysis, the HspX/EsxS fusion protein might be an anti-tuberculosis vaccine candidate in future clinical trial studies.

Abstract
Tuberculosis (TB) remains a major global health threat despite chemotherapy and Bacilli Calmette-Guérin (BCG) vaccination. Therefore, a safer and more effective vaccine against TB is urgently needed. This study evaluated the immunogenicity of a recombinant fusion protein consisting of early secreted antigenic target protein 6 kDa (ESAT-6), culture filtrate protein 10 kDa (CFP-10) and the Fc-domain of mouse IgG2a as a novel subunit vaccine. The recombinant expression vectors (pPICZαA-ESAT-6:CFP-10:Fcγ2a and pPICZαA-ESAT-6:CFP-10:His) were transferred into Pichia pastoris. After SDS-PAGE and immunoblotting, the immunogenicity of the recombinant proteins was evaluated in mice. When both recombinant proteins (ESAT-6:CFP-10:Fcγ2a and ESAT-6:CFP-10:His) were used for vaccination, Th1-type cellular responses were induced producing high levels of IFN-γ and IL-12. However, the Fc-tagged recombinant protein induced more effective Th1-type cellular responses with a small increase in IL-4 as compared to the BCG and ESAT-6:CFP-10:His groups. Moreover, mice primed with BCG and then supplemented with ESAT-6:CFP-10:Fcγ2a produced the highest levels of IFN-γ and IL-12 in immunized groups. The findings indicate that when Fcγ2a is fused to the ESAT-6:CFP-10 complex, as a delivery vehicle, there could be an increase in the immunogenicity of this type of subunit vaccine. Therefore, additional investigations are necessary for the development of appropriate Fc-based tuberculosis vaccines.

Several vaccines against this disease have been developed but none are completely protective. The aim of this study was to design and construct a cloning vector containing the Mycobacterium tuberculosis (M. tuberculosis) heat shock protein X (hspX). METHODS First, an hspX fragment was amplified by PCR and cloned into plasmid pcDNA3.1(+) and recombinant vector was confirmed. RESULTS A 435 bp hspX fragment was isolated. The fragment was 100% homologous with hspX of M. tuberculosis strain H37Rv in GenBank. CONCLUSION In this study, the cloning vector pcDNA3.1(+), containing a 435-bp hspX fragment of M. tuberculosis, was constructed. This could be used as a DNA vaccine to induce immune responses in animal models in future studies.

Abstract
Background: Tuberculosis (TB) is regarded as a health problem worldwide, particularly in developing countries. Mycobacterium tuberculosis (M. tuberculosis) is the cause of this disease. Approximately two billion people worldwide are infected by M. tuberculosis and annually about two million individuals die in consequence. Forty million people are estimated to die because of M. tuberculosis over the next 25 years if the measures for controlling this infection are not extensively developed. In the vaccination field, BacillusCalmette–Guérin (BCG) is still the most effective vaccine but it shows no efficacy in adult pulmonary patients. One of the other problems regarding TB is its appropriate diagnosis. Objectives: In this experimental study, the recombinant cytochrome P450 CYP141 protein of M. tuberculosis was expressed and purified to be used as a vaccine candidate and diagnostic purpose in subsequent investigations. Materials and Methods: The optimization of the cytochrome P450 CYP141 protein expression was evaluated in different conditions. Then, this protein was purified with a resin column of nickel–nitrilotriacetic acid and investigated via Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) and Western Blotting. Results: The highest expression of the cytochrome P450 CYP141 protein was obtained by the addition of 1 mM of isopropyl β-D-1-thiogalactopyranoside (IPTG) to the bacterial culture grown to an optical density at 600 nm (OD600) of 0.6, 16 hours after induction. This protein was subsequently purified with a purification of higher than 80%. The results of Western Blotting indicated that the purified protein was specifically detected. Conclusions: In this experimental study, for the first time in Iran the expression and purification of this recombinant protein was done successfully. This recombinant protein could be used as a vaccine candidate and diagnostic purpose in subsequent investigations.

Abstract
BACKGROUND Helicobacter pylori infection is etiologically associated with some important health problems such as gastric cancer. Because of the high clinical importance of H. pylori infection, development of a noninvasive test for the detection of H. pylori is desirable. METHODS In this study, a loop-mediated isothermal amplification (LAMP) targeted ureC of H. pylori was evaluated on 100 stool specimens and compared with a stool antigen test. Culture and rapid urease test were considered as gold standards. RESULTS The overall detection rate of the fecal antigen test and LAMP was 58% and 82%, respectively. The analytical sensitivity of the fecal antigen test and LAMP was 500 and 10 H. pylori cells/g and 10 fg DNA/reaction, which is equal to six H. pylori genome. CONCLUSION LAMP technique has been characterized by high sensitivity and low detection limit for the detection of H. pylori in stool specimen. Clinical diagnostic performance of LAMP was better than the stool antigen test.

Abstract
This study determined the mechanisms and patterns of antimicrobial resistance among the isolates obtained from different wards of a teaching hospital in the city of Mashhad in north-east Iran. Between January 2012 and the end of June 2012, 36 isolates of Acinetobacter baumannii were collected from different wards of Ghaem Hospital. Antimicrobial susceptibility testing and epsilometer testing (E-test) were performed. The genetic resistance determinants of A, B and D classes of β-lactamases, aminoglycoside modifying enzymes (AMEs), efflux pumps and ISAba1 elements were assessed by PCR. Repetitive extragenic palindromic element (REP)-PCR was performed to find the genetic relatedness of the isolates. Colistin was the most effective antibiotic of those tested, where all isolates were susceptible. E-test results revealed high rates of resistance to imipenem, ceftazidime and ciprofloxacin. The majority of isolates (97 %) were multidrug-resistant. OXA-51, OXA-23 and tetB genes were detected in all isolates, but OXA-58, IMP and tetA were not detected. The prevalence of OXA-24, bla(TEM), bla(ADC), bla(VIM) and adeB were 64, 95, 61, 64 and 86 %, respectively. ISAba1 was found to be inserted into the 5' end of OXA-23 in 35 isolates (97 %). Of the AMEs, aadA1 (89 %) was the most prevalent, followed by aphA1 (75 %). The band patterns reproduced by REP-PCR showed that 34 out of 36 isolates belonged to one clone and two singletons were identified. The results confirmed that refractory A. baumannii isolates were widely distributed and warned the hospital infection control team to exert strict measures to control the infection. An urgent surveillance system should be implemented.

Abstract
Background: The occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the sera or in the liver biopsy and the absence of hepatitis B surface antigen (HBsAg) by serological test. Objectives: The current study aimed to evaluate the occult HBV infection by polymerase chain reaction (PCR) and determine HBV genotyping among the patients with abnormal alanine transaminase (ALT) in Ahvaz city, Iran. Patients and Methods: The sera of 120 patients, 54 (45%) females and 66 (55%) males, with abnormal ALT 40-152 IU were collected. All the patients were negative for HBsAg for more than one year. The patients` sera were tested by PCR using primers specified for the S region of HBV. Then the positive PCR products were sequenced to determine HBV genotyping and phylogenic tree. Results: Of these 120 subjects, 12 (10%) patients including 6 (5%) males and 6 (5%) females were found positive for HBV DNA by PCR, which indicated the presence of occult HBV infection among these patients. The sequencing results revealed that genotype D was predominant with sub-genotyping D1 among OBI patients. Conclusions: Occult hepatitis B infection is remarkably prevalent in Ahvaz, Iran, and should be considered as a potential risk factor for the transmission of Hepatitis B Virus throughout the community by the carriers.

Abstract
Dietary supplements have been used for decades for enhancing muscle growth. The harm caused by some of these products is well documented. We investigated and reported toxic hepatitis in 20 male athletes following self-prescribing of a number of dietary supplements which are lesser known. The patients' ages ranged from 24 to 32 with a mean of 28 years. They had taken three kinds of supplements for 1 year including testosterone optimizer agent T Bomb II, a creatine supplement Phosphagen and an amino acid based supplement Cell-Tech. Based on the history, clinical examination, and laboratory findings the cases were diagnosed as toxic hepatitis. After discontinuation of taking the supplements, clinical recovery and improvement of liver function tests were achieved within 30 days. Causality assessment with the CIOMS (Council for International Organization Medical Sciences) scale showed a "possible" grade of causality (+5 points) for these supplements. It can be concluded that these newer anabolic supplements may induce toxic hepatitis. Since the health risks of them may be severe, the use of these kinds of dietary supplements should be discouraged.

Abstract
Novel vaccines are needed to control tuberculosis (TB), the bacterial infectious disease that together with malaria and HIV is worldwide responsible for high levels of morbidity and mortality. TB can result from the reactivation of an initially controlled latent infection by Mycobacterium tuberculosis (Mtb). Mtb proteins for which a possible role in this reactivation process has been hypothesized are the five homologs of the resuscitation-promoting factor of Micrococcus luteus, namely Mtb Rv0867c (rpfA), Rv1009 (rpfB), Rv1884c (rpfC), Rv2389c (rpfD) and Rv2450c (rpfE). Analysis of the immune recognition of these 5 proteins following Mtb infection or Mycobacterium bovis BCG vaccination of mice showed that Rv1009 (rpfB) and Rv2389c (rpfD) are the most antigenic in the tested models. We therefore selected rpfB and rpfD for testing their vaccine potential as plasmid DNA vaccines. Elevated cellular immune responses and modest but significant protection against intra-tracheal Mtb challenge were induced by immunization with the rpfB encoding DNA vaccine. The results indicate that rpfB is the most promising candidate of the five rpf-like proteins of Mtb in terms of its immunogenicity and protective efficacy and warrants further analysis for inclusion as an antigen in novel TB vaccines.
