Abstract: Tuberculosis is the second lethal infectious disease caused by Mycobacterium species. This pathogens could cause severe disease like tuberculosis and leprosy in human. Today there are a number of anti tuberculosis agents utilized in treatment of this disease but multiple drug resistance is one of the major problems that end to failure in treatment. Dendrimers are synthetic, high branched polymers with a number of functional groups that could bind to different macromolecules like drugs, oligosaccharides that makes i…

Abstract: Differential diagnosis of Entamoeba spp. has great clinical and epidemiological importance. Entamoeba moshkovskii cysts and trophozoites are morphologically indistinguishable from Entamoeba dispar and Entamoeba histolytica. This study was carried out for the first time to detect Entamoeba spp. in stool samples by using molecular method from April 2010 to December 2010 in Khorramabad, Iran. A total of 862 fecal specimens were collected from patients having abnormal gastrointestinal symptoms and who were referred to…

Abstract: The complete genome of the foot-and-mouth disease virus (FMDV) strain WFL was cloned and sequenced. The results showed that the complete genome was 8155 nucleotides (nt) in length (including the poly(C) tract, but excluding poly(A) tail) and was composed of a 1059-nt 5'-untranslated region (UTR), a 6969-nt open reading frame, and a 127-nt 3'-UTR. CRE region of 5’UTR was 55nt with 45.5% of G/C, and had a stem-loop. The stem-loops region of 3’UTR can fold into two stem-loops, SL1 and SL2. A phylogenetic tree was cons…

Abstract: The sugar waste (molasses) was tested for various physiochemical parameters. After examination of various physiochemical parameters, growth and population count of Rhizobium meliloti MTCC-100 was monitored at different concentrations of sugar waste (10, 20, 30 and up to 100%) in terms of optical density (OD) and colony forming unit (C.F.U.). Growth and cell count of Rhizobium were highest in 10% sugar waste concentration. Growth pattern of the bacteria was observed at 10% sugar waste along with different synthetic…

Abstract: Five bacterial isolates (B-CP5- B-CP6 - B-CP7- B-CP8- B-CP9) were isolated from pesticides-contaminated soil in Egypt. The capability of these isolates to degrade chlorpyrifos was investigated using enrichment mineral salt (MS) medium containing chlorpyrifos. Two different PCR-based techniques, RAPD-PCR and PCR-RFLP for amplified16S rRNA fragment were used to conduct genetic fingerprinting and obtain specific molecular markers for the studied isolates. The isolates exhibited substantial growth in mineral salt mediu…

Abstract: Opaque sorghum beers are traditional alcoholic beverages in several African countries. Known as tchoukoutou in Benin, the beer is often obtained from an uncontrolled fermentation. It is consumed in an actively fermenting state and has a sour taste. The present study characterized and identified the yeasts involved in the fermentation process of this type of beer using the phenotypical approach. Of 12 beers from 4 different locations, the mean values of the pH, titratable acidity, dry matter content and refractive i…

Abstract: Advanced bioremediation in waste water and sewage treatments currently represents one of the important aspects of biotechnology. The removal of pathogenic microorganisms, complex hydrocarbons, heavy metals and nutrients were intensively investigated. The present work aims to improve the efficiency of involved bacteria in aeration tanks for maximizing mineralization process of organic substances and consequently reduce the time of the treatment process. Other target is the elimination of nutrients (N & P) to avoid t…

Abstract: The purpose of this study is to investigate the effects of four weeks judo training on plasma leptin levels. Twenty-five female national team athletes with a mean age of 18.12±1.12 years; body weight of 62.72±22.72 kg; body height of 164.28±7.28 cm, BMI of 23.17±6.28 kg/m2; training experience of 6.56±5.44 years participated in this study. The data were collected from junior female judokas who trained six times in a week for two hours daily. Physical measurements and blood samples were taken before and after four w…

Abstract: In Behcet’s disease (BD) and Brucellosis, joint involvement is very common and it may share similarities with rheumatoid arthritis (RA). Anti-cyclic citrullinated peptides (CCP) are evaluated as more specific autoantibodies than rheumatoid factor (RF) in RA. The aim of this study is to determine whether anti-CCP antibodies are useful in the differential diagnosis of RA from other arthritis or not. 153 serum samples were used in the study; 34 from RA patients, 26 from brucellar arthritis, 20 from BD with arthritis…

Abstract: The cold extraction method was used to obtain the methanol extract of the leaf of Combretum mucronatum. The extract was analyzed for antibacterial activities, using some pathogenic bacteria namely: Klebsiella pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Bacillus cereus, Salmonella typhi and Bacillus subtilis. The antibacterial bioassay was carried out in-vitro and it revealed that the methanol leaf extract inhibited the growth of the tested…

Abstract: In order to determine whether infection with Helicobacter pylori and CagA strain is associated with hyperemesis gravidarum (HG), a study was conducted in Al- Zahra obstetrics and gynecology hospital in Tabriz, Iran between May 2007 and February 2008. Forty-four (44) pregnant women with the diagnosis of HG and forty-four (44) normal pregnant women of matched gestational age were included in this prospective study. Serum H. pylori immunoglobulin G antibody titer and CagAantibodies were measured for both groups of wom…

Abstract: The plasmid pJB01 contains a single operon consisting of three orfs, copA, repB and repC cistrons. The operon, also called repABC operon, starts transcription at T695 or A696 on the pJB01 genetic map. CopA (called RepA in pMV158 family) or ctRNA (counter-transcript RNA) of this plasmid play roles as a repressor of RepB, a replication initiator, on the transcriptional and translational level, respectively. RepC did not bind 73 bp PCR product including three tandem repeats (5′-CAACAAA-3′), the binding sites for RepB…

Abstract: An antagonist bacterium ZQ2 was isolated from an apple rhizosphere at Mount Tai in China. The bacterium strongly inhibited the growth of numerous apple phytopathogens in vitro, such as Rhizoctonia solani, Fusarium oxysporum, Fusarium solani, and Physalospora piricola. The inhibition rates against the different fungi ranged from 55.26 to 88.17. The strain ZQ2 was identified as Brevibacillus laterosporus based on morphology, biochemical tests, and 16S rDNA sequence analysis. The antifungal metabolites produced by ZQ2…

Abstract: In this study the potential of the previously contracted recombinant clone ABA392 derived from PASTEURELLA MULTOCIDA serotype B to protect laboratory animal against haemorrhagic septicaemia was determined. After reconfirmation of plasmid DNA size, its stability and pathological effect of the clone, passive mice protection test and active immunization was carried out. Pooled serum sample from rats vaccinated with live and killed form of the clone was administered to mice and provided 66% protection while active immu…
