“Mycobacterium tuberculosis (M.tb) causes 1.7 million deaths per year [1]. The current vaccine Bacille Calmette Guerin (BCG) is the most widely used vaccine in the world but has variable efficacy in children, ranging from 0% to 80%, and poor efficacy in adults. Therefore better vaccines against M.tb are urgently required, especially as the frequency of drug-resistant isolates continues to rise. A range of new generation vaccines are currently in various stages of clinical development, including modified BCG strains, proteins,

DNA and virally vectored subunit vaccines (reviewed in [2]). Understanding the mechanisms by which these candidates mediate protection will allow them to be used to the greatest effect as well as aiding more rational design of further generations of vaccines. Recombinant adenovirus serotype Hu5 expressing antigen 85A from M.tb (Ad85A) is one such candidate vaccine and has shown protection in mice and guinea pigs when given by the intra-nasal (i.n.) route [3], [4] and [5]. Administration of the vaccine i.n. generates a large population of 85A-specific CD8+ T-cells in the lung, which correlates with protection [3], [6], [7], [8], [9] and [10]. 17-DMAG (Alvespimycin) HCl Furthermore, Santosuosso et al. have shown that the location of the antigen-specific cells in the lungs plays an important role in protection [7]. However, there is little information as the role of upper respiratory tract (URT) associated lymphoid tissue in protection against M.tb challenge. In mice, one of the principal lymphoid tissues associated with the URT is the nasal-associated lymphoid tissue (NALT). The NALT, which is thought to be an inductive site for immune responses in the URT [11] is a lymphoid structure at the back of the nasal cavity above the hard palette, often compared to Waldeyer’s ring in humans, and has been described as having similar functions to the better studied gut-associated lymphoid tissue (reviewed in [12] and [13]).

2D gel spots were transferred to protein LoBind tubes (Eppendorf,

2D gel spots were transferred to protein LoBind tubes (Eppendorf, Hamburg, Germany) and destained with 50% acetonitrile in 50 mM ammonium bicarbonate for 1 h. In-gel tryptic digestion and peptide extraction were carried out manually as described [12]. For matrix-assisted laser desorption ionization—time of flight (MALDI-TOF) MS analysis, digests were desalted and concentrated using a ZipTip C18 (Millipore) following the manufacturer’s instructions [12] and mixed with α-cyano-hydroxy-cinnamic acid (10 mg/mL in 50% acetonitrile/0.1% trifluoroacetic acid) prior to spotting onto a MALDI target (Bruker Daltonics, Coventry, UK). An Autoflex II

MALDI-TOF/TOF mass spectrometer (Bruker Daltonics), equipped with FlexControl software, was used for acquisition of mass spectra. A total of 700 laser shots per sample were acquired by summing sets of 50 laser shots. Rucaparib in vivo MS/MS spectra were acquired by application of LIFT™-TOF technology on the most intense parent ions. A Surveyor LC system (Thermo Electron), directly interfaced with an ion trap mass spectrometer (LCQ Deca

XP) equipped with an electro-spray ionization (ESI) source (Thermo Electron), was also used for capillary LC–MS/MS analysis of some protein digests [12]. MS scans were performed over a m/z range of 400–2000 and MS/MS scans of the most intense peaks were carried out in a data-dependent Apoptosis inhibitor acquisition manner. For MALDI, a list of peptide or fragment ion masses was generated using FlexAnalysis software and imported with BioTools (Bruker Daltonics) to a web-based Mascot search engine (Matrix Science, London, UK) for protein identification via peptide mass fingerprinting (PMF) and MS/MS sequencing using the SwissProt and NCBInr N. meningitidis entries. For ESI-MS/MS, sequence files were created and searched using the Sequest algorithm in Bioworks v.3.1 software (Thermo Electron) and the N. meningitidis MC58 entries (UniProtKB/SwissProt release 56.4). A positive protein identification only was assigned when at least two peptides passed the single threshold filter by Xcorr (1.50, 2.00, 2.50) versus charge state (±1, 2, 3), respectively. Other search parameters included cysteine carbamidomethylation as a fixed

modification; methionine oxidation as a variable modification; peptide and MS/MS mass tolerance set out at 100 ppm for MALDI and 0.5 and 0.6 Da for ESI-MS and -MS/MS, respectively. Peptide charges of +1 for MALDI and +1, +2, +3 for ion trap were selected, and one trypsin miss-cleavage was allowed. Differences in antibody levels were determined with Student’s t-test or Mann–Whitney rank sum test using a SigmaStat 3.1 program (Systat Software, Chicago, USA). p-Values <0.05 were considered significant. Correlations were assessed by the Spearman rank order correlation test or Pearson product moment correlation test. For DIGE analysis, Student’s t-test was applied to identify protein spots with significant differences in fold changes between the two compared groups.

Samples and survey data were collected during the dry months of J

Samples and survey data were collected during the dry months of June–August of 2004, coinciding with Nutlin-3 chemical structure the period of increased malaria transmission in Rondonia State. Written informed consent was obtained from all adult donors or from parents of donors in the case of minors. The study was reviewed and approved by

the Fundação Oswaldo Cruz Ethical Committee and the National Ethical Committee of Brazil. To evaluate epidemiological factors that may influence the cellular immune response against PvMSP9, all donors were interviewed upon informed consent. Questions in the survey related to demographics, time of residence in the endemic area, personal and family histories of

malaria, use of malaria prophylaxis, presence of malaria symptoms, and personal knowledge of malaria. Survey data was recorded and entered into a database created with Epi Info 2002 (Centers for Disease Control and Prevention, Atlanta, GA). Venous peripheral blood was collected into heparinized tubes, and peripheral blood mononuclear cells (PBMC) were isolated by Ficoll/Hypaque (Pharmacia, Piscataway, NJ) density gradient centrifugation and used in the ELISPOT BLU9931 datasheet assays within the first 12 h after collection. Plasma was stored at −20 °C and thin and thick blood smears of all donors were examined for malaria parasites. Parasitological evaluation by examination of 200 fields at 1000×

magnification under oil-immersion, all slides were examined by a researcher expertise those in malaria diagnosis. Donors positive for P. vivax and/or P. falciparum at the time of blood collection were subsequently treated per the chemotherapeutic regimen recommended by the Brazilian Ministry of Health. HLA-DR binding frames along the primary structure of PvMSP9 were detected by ProPred analysis. The amino acid sequence of PvMSP9 was scanned to identify promiscuous MHC binding peptides using virtual matrices designed for 51 HLA-DR alleles [15]. Eleven sequences were identified within the N-terminal region of PvMSP9 which were predicted to bind at least 40% HLA-DR alleles included in the ProPed algorithm at a 3% threshold. Synthetic peptides representing such putative T-cell epitopes were synthesized at the Laboratory of Biochemistry of Proteins and Peptides, Institute Oswaldo Cruz, Fiocruz. The complete amino acid sequences of five out of 11 synthetic peptides (including 3 overlapping regions) that induced the highest cellular response and the relative amino acid position were: (1) peptide pE (V147–K159), VVHKLNKKMKSLK; (2) peptide pH (V438–D449), VSLMASIDSMID; (3) peptide pJ (K325–I339), KLKDILLRVLYKTYI; (4) peptide pK (P434–I448), PAEDVSLMASIDSMI and (5) peptide pL (A443–K456), ASIDSMIDEIDFYEK.

No clear

relationship was apparent between the titre of specific antibody measured to the individual vaccine antigens and the number of cysticerci detected at necropsy following the challenge infection with T. solium. Pig antiserum raised against TSOL16-GST showed no cross-reactivity with TSOL18-MBP in direct ELISA. Similarly, pig antisera raised against-TSOL18-GST showed no cross-reactivity with TSOL16-MBP. In inhibition ELISAS, addition of the homologous combinations of antigen and antisera (TSOL16 and anti-TSOL16, TSOL18 and anti-TSOL18) led to total inhibition of the sera’s reactivity in ELISA, however no inhibition was evident when heterologous combinations

of antigen and antisera (TSOL16 and anti-TSOL18, TSOL18 and anti-TSOL16) were used (data not shown). The results of the vaccine trial in which pigs were immunized with the TSOL16 recombinant antigen demonstrates selleckchem that the antigen is able to confer high levels of protection against challenge infection with T. solium ( Table 1). The homologous antigen from T. ovis, To16, was first identified from an oncosphere cDNA library by immuno-screening with antiserum raised against a 16 kDa oncosphere buy Hydroxychloroquine antigen [9], following experimental fractionation of protein extracts of the oncosphere and testing these extracts in sheep vaccine trials. The resulting To16 recombinant antigen was shown to reduce T. ovis infection in vaccinated lambs by 92%. These findings provided the basis for identifying a homologous

antigen in T. solium [8], thereby eliminating the requirement for testing of native T. Rolziracetam solium antigens in pig vaccine trials and increasing the likelihood of isolating a recombinant antigen that is protective against T. solium cysticercosis. A similar strategy was successful for developing the TSA9/TSA18 vaccine for T. saginata [19] and the TSOL18 vaccine antigen against porcine cysticercosis [4] and [20]. The host-parasite relationship in cestodes offers a number of advantages in relation to the likelihood of successful development of vaccines [21], nevertheless the successes that have been achieved with cestode parasites contrasts with broader strategies based on genomic/transcriptomic/proteomic studies [22], [23], [24], [25], [26] and [27] where isolation of large numbers of candidate vaccine antigens can be problematic for the discovery of protective antigens. In the experiment described here, TSOL45-1A did not provide statistically significant levels of protection against T. solium infection ( Table 1). This contrasts, however, with previous studies which demonstrated that pigs vaccinated with TSOL45-1A can be protected against T. solium infection [4] and [5]. Flisser et al.

Data. 7-Aryl-7H-bis [1] benzopyrano [4,3-b: 3', 4'-c] pyran-6, 8-dione (4d): 0.5 g m.p 323 °C. IR (KBr): 1350, 1430, 1600, 1640–1650, 1700, 2820 cm-1. 1H NMR (CDCl3, 400 MHz): δ 7.5–7.9 (12H,m,ArH),4.98 (1H,s,-CH-). m/z 419 (M+), 392, 317, 265, 196, 121, 94 and 60. Same results were obtained when the reaction was carried out at water bath temperatures. A mixture of DMSO (10 ml), acetic anhydride (5 ml) and (1e) (1.5 g) was kept at room temperature for 9 days. A yellow crystalline product

which separated out was filtered, washed and crystallized from benzene and identified as 7-Aryl-7H-bis [1] benzopyrano [4,3-b: 3′, 4′-c] pyran-6, 8-dione (4e). The mother liquor upon addition of water and extraction with

ethyl this website acetate afforded a solid which was crystallized from benzene and identified as (9). Data. 7-Aryl-7H-bis [1] benzopyrano [4,3-b: 3', 4'-c] pyran-6, 8-dione(4e): (0.5 g) IR (KBr): 1250, 1360, 1600, 1655 and 1720 cm−1. 1H NMR (DMSO-d6, CFT-20): δ 7.45–8. (12H,m,ArH),6.2 (1H,s,-CH-). m/z 422(M+), 409, 393, 317, 265, 176, 121 and 120. (Found C, 68.48; H, 2.58. C25H13NO7 required C,68.33; H, 2.96%). Product (9): m.p 271 °C; (1.6 g). IR (KBr): 1410, 1640, 1700, 1760, 2850 and 3350 cm−11H NMR (CDCl3 EM 390 90 MHz): δ 7–8.25(12H,m,ArH),4.75 (1H,s,-CH-), 3.77(2H,s,-CH2-), 2.84(1H,s,-OH-). m/z 487, 440, 365, 249, 175 and 121. (Found C, 64.18; H, 3.27. C26H17NO9 requires C,64.06; H,3.49%). At room temperature DMSO-acetic anhydride converts (1a) obtained easily by the reaction of 4-hydroxycoumarin with benzaldehyde,5 to a novel product (3) in excellent yields. On the basis of its mass spectrum and elemental analysis the molecular formula of the compound comes out to be C25H14O6 .Two structures (2a) and (3) were possible for the compound but the former is ruled out on the basis of proton magnetic resonance (pmr). The Thalidomide 1H singlet at δ 4.73 can be assigned to the benzylic and allylic proton. The carbonyl bands at 1790, 1720 and 1680 cm−1

in the infrared spectrum are also at right values for saturated lactone, coumarin and benzoyl carbonyl groups respectively. The treatment of (la) with DMSO-acetic anhydride at 160 °C, proved destructive. At water bath temperature, however, a yellow crystalline solid (4a) gradually separated from the reaction mixture and was filtered off at the end of reaction. Its pmr spectrum shows in addition to thirteen aromatic protons, a singlet at δ 5.17 belonging to doubly allylic and benzylic methine proton suggesting structure (4a) for the compound which was further confirmed by infrared spectrum showing a broad signal at 1720 cm−1 and 1655 cm−1 for two, α–β-unsaturated lactone carbonyls and for enol ethers respectively.

3%) of all RV-A positive samples (n = 215), and only “G” or “P” types in 21 samples. There was a predominance of the G2P [4] genotype (51.3%, n = 80) followed by G1P [8] (15.4%, n = 24). Of all Autophagy inhibitor cost observed genotypes, G2 was found in 57% (n = 89) and G1 in 23% (n = 36). The other genotypes characterized were: mixed groups (n = 14), G9 (n = 6), G3 (n = 3), and unusual strains such as G12 (n = 2) and Group C (n = 1). Mixed infections and

unusual genotypes were identified in 10.9% of the RV-A positive samples. The two-dose adjusted VE (adjusted for year of birth and the frequency matching variables) was 76% (95%CI: 58–86) (Table 1). Effectiveness controlled by the available potential confounders was very similar (72%, 95%CI: 44–85), suggesting no appreciable confounding by those factors for which adjustment was made. We excluded a similar proportion of cases (5.7%) and controls (5.3%) because they did not have cards. Sensitivity analysis showed that

if they were included as vaccinated, VE (two doses) would be 66% (95%CI: 42–80) and if included as unvaccinated VE would be 74% (95%CI: 53–86). The VE (adjusted for year of birth and the frequency matching variables) for one dose was 62% (95%CI: 39–97) and one dose VE adjusted for other potential confounders was 60% (95%CI: 37–75). Table 2 shows that VE was similar in those with time since second dose vaccination until hospitalization stratified by one year (71%; 95%CI: 54–82) and Dabrafenib purchase two years (78%; 95%CI: 52–90). The VE for G1P[8] and G2P[4] by time since second dose vaccination was marginally higher for G1P[8](90%; 95%CI:-0.92–-100 for one year and 89%; 95%CI: 0.01–-99 for two years) than SPTLC1 G2P[4] (77%; 95%CI: 57–88 for one year and 75%; 95%CI: 56–86 for two years) significant. Table 3 presents genotype-specific VE by number of doses. VE (two doses) was 89% (95%CI: 78–95) for G1P[8]; 76% (95%CI: 64–84) for G2P [4]; 74% (95%CI: 35–90) for all G1; 76% (95%CI: 63–84) for all G2 and

63% (95%IC: −27–99) for all the non G1/G2 genotypes. Estimated VE remained very similar when analysis was stratified by year of admission suggesting that VE did not change with increasing vaccine coverage (data not presented). Two-dose VE was 76% (95%CI: 44–85), in spite of the great diversity of rotavirus genotypes circulating in Brazil and a predominance of G2P[4] genotype (51.3%). We found a 10.9% mixed and unusual genotypes as expected in developing countries [31] and [32]. The VE lasted for two years after second dose vaccination and it was higher for G1P[8] than G2P[4]. Variation of RV-A vaccine efficacy and effectiveness have been reported in the literature: efficacy was higher in Europe (96.4% against RV-A severe AD) [11] than in a low income country (Malawi, 49.2% against all diarrhea and 57.5% against hospitalized diarrhea) [13] and in countries with high mortality (63%) [33].

The neem leaf extract was prepared by crushing 100 g of neem leav

The neem leaf extract was prepared by crushing 100 g of neem leaves in water and soaking in water overnight; the neem seed kernel – V. negundo leaf extract was prepared by taking 100 g each neem seed kernel powder and V. negundo this website leaves. They are then crushed and soaked in water overnight and filtered before use for field trials. The 2nd, 3rd, 4th and 5th instar larvae

were grown in plastic containers covered by a muslin cloth for aeration. Each container consists of 10 larvae and three replicates were maintained. Ten milliliters of spore suspension of the fungi were taken in which each larva was dipped thoroughly for 10 s. The control larvae were dipped in 0.02% Tween 80 alone. The containers with larvae were maintained at 26 ± 1 °C temperature; relative humidity 70 ± 10% and photoperiod of 16:8 L:D. Larval mortality was recorded at every 24 h interval for seven days after treatment and the data was analyzed statistically. The cadavers were used for re-isolating the pathogen in pure culture for confirming the pathogenicity of fungi. The larvae were fed twice a day with a specially formulated diet (slightly modified diet of6) which GSK1120212 research buy consists of caesin-10 g, sucrose-20 g,

ascorbic acid-2 g, Brewer’s yeast-2 g, sorbic acid-0.65 g, formaldehyde-1 ml, agar-6 g, turmeric leaves-50 g and water-275 ml. The unfed feed and leaves were removed periodically. Field trials were conducted for two years at one of the turmeric farms in Karungalpalayam, Erode, Tamil Nadu, India during 2010–2011 in randomized complete block design having 11 treatments which includes an untreated control plot with three replicates for each treatment. Each treatment plot size was 10 m2 with 50 plants in each plot. Treatments were applied as foliar sprays and comprised as follows: T1 – M. anisopliae; T2 – B. bassiana; T3 – Standard N. rileyi (MTCC 4175); T4 – Standard H. citriformis (MTCC 6800); T5 – H. citriformis

HC28; T6 – N. rileyi NR07; T7 – Neem leaf extract; MTMR9 T8 – Neem seed kernel + V. negundo leaf extract; T9 – Commercial Biopesticide (Biopower®); T10 – Acephate; T11 – Untreated control. The spraying of bioformulations was done using a Knapsack sprayer with a spray volume of 300 L ha−1. The treatment sprays were applied twice at two days interval. Soap powder (2 g/L) and/or starch powder was added to enhance the adhesiveness of the sprays as the whole experiments were conducted during rainy season.10 The observations were recorded on ten randomly selected plants in each plot. Data on the death of larval population after 3, 5 and 7 days after spraying were calculated.

The 63 synthetic compounds that were used in the screen for inhib

The 63 synthetic compounds that were used in the screen for inhibitors of the ESX–Sur2 interaction were provided by Professor Younghwa Na (College of Pharmacy, Cha University). These compounds have diverse core structures and include the following: 9 3-(3′-heteroatom substituted-2′-hydroxy-1′-propyloxy) xanthone analogues; 13 2,5,7-heteroatom substituted

chroman-4-one analogues; 13 benzosanthen-12-one derivatives; 12 4-hydroxy-2′-nitrodiphenyl ether analogues; 9 methyloxiranylmethoxyxanthone analogues; and 7 fluoroquinophenoxazine derivatives. Adriamycin, etoposide, click here camptothecin, canertinib and BMS599626 were purchased from Sigma–Aldrich (St. Louis, USA). Wrenchnolol was provided by Professor Uesugi (Kyoto University, Japan). All of the compounds used in the present study were dissolved in dimethylsulfoxide (DMSO; Sigma–Aldrich, St. Louis, USA) to form 10 mM stock solutions and stored at −20 °C until needed. Human breast cancer cell lines (MCF-7, MDA-MB231, T47D, SK-BR-3) and a human kidney cell line (HEK293) were purchased from the Korean Cell Line Bank (Seoul, Korea). AU-565 (human breast adenocarcinoma cell line) and MDA-MB468 (human breast cancer cell line) were kind gifts from Dr. Seung Bae Rho (National Cancer Center, Korea) and Dr. Yung-Jue Bang (College of Medicine,

Seoul National University, Korea). All cell lines except HEK293 were maintained in Roswell Park Memorial Institute Medium (RPMI 1640, WelGENE Inc., Daegu, Korea) that was supplemented with 10% fetal bovine serum (FBS, WelGENE Inc. Daegu, Korea) and 1% penicillin–streptomycin (Hyclone laboratories find more Inc., Rockford, IL, USA). HEK293 was cultured in Dulbecco’s Modified Eagle Medium (DMEM, WelGENE Inc., Korea) with 10% FBS and 1% penicillin–streptomycin. These cells were grown

at 37 °C in a humidified atmosphere containing 5% CO2. The cells were seeded in 96-well microplates at a density of 1–2 × 104 cells per well and incubated overnight in 0.1 mL of medium supplemented with 10% FBS and 1% penicillin–streptomycin at 37 °C in a because 5% CO2 incubator. On day 2, after 4 h of FBS depletion, the compounds were treated by exchanging the media with 0.1 mL aliquots of medium containing graded concentrations (0, 0.1, 0.25, 0.5, 1, 2 and 5 μM as a final concentration). After 48 h of treatment, 5 μL of cell counting kit-8 (Dojindo, Kumamoto, Japan) was added to each well followed by an additional 4 h of incubation under the same conditions. The absorbance of each well was determined using an Automatic Elisa Reader System (Bio-Rad 3550, Ramsey, MN, USA) at a wavelength of 450 nm. The viability of cells treated with CHO10 was calculated from the absorbance, with untreated cells assumed to be 100% viable. The cells were seeded in 60 mm dishes at a density of 5 × 105 cells per dish and incubated until the cells reached a confluence of 80%.

Also the function score, which distinguishes mild from severe inj

Also the function score, which distinguishes mild from severe injuries, could not be taken into account because it is not registered in the network. Another limitation is the altered definition of acute injuries and functional instability, which means that patients in which mTOR inhibitor cancer the trauma occurred five or six weeks earlier are considered to have functional instability in the current study, whereas they have an acute ankle injury according the guideline. This means the percentage of patients with acute injuries is probably larger than is stated here. It could also be that adherence to the guideline in the group of

patients with functional instability is somewhat overestimated. One limitation, which does not only apply to LiPZ, is that the patients’ opinion is not represented on relevant outcome measures, eg, whether treatment goals were

accomplished. Nevertheless, the current study provides more objective information on guideline adherence by physiotherapists. From these findings it is obvious that additional research on practice guidelines is necessary to explore the use or nonuse of practice guidelines. Some specific topics, such as the use of manual manipulation as an intervention directed at body functions, and the variance between physiotherapists on guideline adherence based on the number of patients they treat, also ask for more in-depth research. Such data could contribute to the debate about whether all physiotherapists should PARP inhibitor specialise in certain areas or some should remain general

physiotherapists. None declared. Support: Ministry of Health, Welfare and Sport, The Netherlands. “
“The importance of physical activity to health is well established. Regular physical activity is critical for decreasing and maintaining body weight, blood pressure, total blood cholesterol, serum triglycerides, and low-density lipoprotein cholesterol (Franklin and Sanders 2000). In addition, it can play an antithrombotic role by reducing blood viscosity (Koenig et al 1997), fibrinogen levels (Ernst 1993), and platelet aggregability (Rauramaa et al 1986). There is evidence from a meta-analysis of cohort studies that physical activity has a neuroprotective effect against Linifanib (ABT-869) stroke and may decrease stroke incidence (Lee et al 2003, Wendel-Vos et al 2004) and the incidence of recurrent strokes (Gordon et al 2004). There is growing evidence that the free-living physical activity of people with stroke is less than that of healthy controls. Studies have used different devices to measure activity including step activity monitors (Manns et al 2009, Michael and Macko 2007, Michael et al 2005, Rand et al 2009) and accelerometers (Hale et al 2008). Activity levels for community-dwelling people with stroke as low as 1389 steps/day have been reported (Michael et al 2007).

angustifolia leaf and to find out minimum inhibitory concentratio

angustifolia leaf and to find out minimum inhibitory concentration (MIC) of different extracts against Garm negative bacteria. Aerial part (leaves) of T. angustifolia was collected in and around the Gulbarga, Karnataka, India in the month of January 2012 and the plant was duly identified and authenticated in the Herbarium of the Department of Post Graduates Studies and Research in Botany, Gulbarga University, Gulbarga, Karnataka, India. The collected leaves were washed with running tap water and allowed

to air dry. The plant materials were dried in shade for two to four weeks. Precaution was taken to avoid direct sun light otherwise it will destroy the active compounds of plant leaves. After drying, the plant leaves were grinded finely and stored in airtight container. The air GSK126 ic50 dried leaf powders (50 g) were successively

extracted by soxhlet extraction with solvents of increasing polarity i.e., petroleum ether (60–80 °C), chloroform, methanol and distilled water. The extracts were dried and stored in a sterile container for further use. The finely powdered leaves of T. angustifolia Linn was subjected to various physicochemical studies for determination of ash value like total ash, acid insoluble ash and water soluble ash. 7 Extractive values like water soluble, methanol soluble, chloroform soluble and petroleum ether soluble Selleckchem Hydroxychloroquine were determined. The phytochemical components of the T. angustifolia leaves were screened for using the standard method described by Harbone. 8 The components analyzed are alkaloids, proteins, glycosides tannin, steroids, phenol, saponins, flavonoids, carbohydrates, oils and fats. The micro organisms used for

testing were Enterobacter aerogenes (MTCC111), Salmonella typhimurium (MTCC 98), Klebsiella pneumonia (MTCC 109), Pseudomonas aeruginosa(MTCC 424), Escherichia coli (Clinical strain). The above organisms were obtained from the department of Microbiology and Biotechnology, Gulbarga University, Gulbarga, Karnataka, India. 200 μl of overnight cultures of each micro organisms was dispensed into 20 ml of sterilized nutrient broth and incubated at 37 °C for 4–6 h to standardize the culture to 106 CFU/ml. A loopful of the standard cultures was used for the antimicrobial assay.9 In vitro antibacterial activities of all different Resveratrol extracts of T. angustifolia were determined by standard agar well diffusion assay. 10 Muller–Hinton Agar (MHA) plates were seeded with 18 h old culture of the isolates. Different extracts were dissolved in 1% Tween 80 in deionized water and made the final concentration of 50 mg/ml, from this 50 μl of different extracts were added into the sterile 6 mm diameter well. 1% Tween 80 and sterilized distilled water were used as negative controls while chloramphenicol antibiotic disc (30 mcg, Hi-Media) was used as positive control.
