Different parts of Jatropha curcas L. has been traditionally used for medicinal purposes to cure various diseases. In the present study the comparison of antibacterial activity of latex, leaves and their various extracts (methanolic and ethanolic) has been investigated against Escherichia coli (gram negative species) and Staphylococcus aureus (gram positive species) by using disc diffusion method. Antibacterial activity of pure latex and its ethanolic extracts has been found only against E. coli. But the ethanolic extract of leaves of Jatropha curcas L. showed antibacterial activity against both the bacterial test species. Methanolic extract of latex as well as leaves also exhibit antibacterial activity against both Escherichia coli and Staphylococcus aureus. The magnitude of antibacterial activity against Escherichia coli and Staphylococcus aureus found to be significantly higher in latex and its extracts as compare to leaves. Antibacterial activity of latex and its extracts found to be higher then the antibacterial activity of standard tetracycline as compared to leaves extracts.

It was a study to investigate the Antibacterial Activity of Some Medicinal Plants Used against UTI Causing Pathogens. Bacteria were isolate from the UTI infected patient and characterized by using microscopic, staining, morphological and biochemical methods. Oils from plants were extracted using Clevenger and these oils were than used to check their antibacterial activity against the bacteria isolated from UTI infected patients and the zone of inhibition were compared with the zone of inhibition of standard antibiotics. Results from the present study showed that ajwain oil had more antibacterial activity compared to other oils we used and Fennel oil had lowest antibacterial activity. © 2012 IJDDR, Amit Kumar et al.

A thermostable alkaline protease producing strain identified as Bacillus subtilis MTCC 9226 was isolated from cow dung compost sample. Culture conditions were optimized for protease production. Maximum enzyme production was detected in stationary phase with Bacillus subtilis MTCC 9226 at 45° C, pH 9.0 with 5% inoculum after 32 h incubation. The optimum temperature and pH for the activity of this protease were 45°C and 9.0 respectively. Out of various carbon and nitrogen source tested, glucose (1%) and yeast extract (0.5%)+peptone (5%) proved to be very good source/s of carbon and nitrogen respectively for the production of protease by this organism. The enzyme was stable from pH 7.0 to 11.0 at temperature 30° C to 60° C. Activity of protease increased in presence of 4mM Mg2+ (107%) and was slightly effected by EDTA 50mM (79%) and completely inhibited by SDS. The enzyme activity was stable up to in 15% of H2O2 and sodium hypochlorite and inhibited at higher concentrations. The enzyme was very stable in benzene (97%) followed by methanol (86%). Complete removal of gelatin from X-ray films was achieved in 25 min at 45°C.

A systemic study of fungal endophytes associated with different plant parts of Cannabis sativa and their antifungal activity was investigated in the present study. A total of 281 plant segments, including 91 leaves, 93 stem and 97 petioles samples, were screened for the isolation of endophytic fungi. Totally, 212 (77.65%) segments were found colonised by different fungi. Highest colonisation frequency were observed in stem parts (84.94%), then leaves (82.41%) and lowest 59.79% in petiole. Total eight fungal genera belonging to 12 species were isolated. Aspergillus is recorded as the most frequently occurring genera with three species Aspergillus niger, Aspergillus flavus and Aspergillus nidulans followed by Penicillium with two species Penicillium chrysogenum and Penicillium citrinum, while Phoma, Rhizopus, Colletotrichum, Cladosporium and Curvularia with single species. The antifungal potential of A. niger and A. flavus - two most frequently isolated endophytic fungi - was evaluated against two common plant pathogen, Colletotrichum gloeosporioides and Curvularia lunata. Different plant and fungal extracts individually and in combinations showed variations in antifungal activity against both the pathogens. The primary results obtained on antifungal activity of endophytes show their possible role in plant defence mechanism but it is a preliminary approach and more extensive research is still required. © 2013 Copyright Taylor and Francis Group, LLC.

Fungal endophytes were isolated from surface sterilised leaf segments of five medicinal plants collected from Mandi district, Himachal Pradesh, India. A total of 373 fungal strains belonging to 15 fungal genera and 18 species, Aspergillus niger, A. flavus, A. clavatus, A. variecolor, Penicillium chrsogenum, Alternaria alternata, Curvularia lunata, Haplosporium sp., Phoma sp., Nigrospora sp., Colletotrichum sp., Cladosporium sp., Stemphylium sp., Fusarium sp., Geotrichum sp., Phomopsis sp., Trichoderma sp., Rhizopus sp. and some sterile mycelium were isolated from all the plants. The relative frequency, isolation rate and colonisation rates of endophytes were used to study the endophytic diversity. The results showed that the highest colonisation rate (93.05%) was observed in Adhathoda vasica, while it was 91.66% in Ocimum sanctum, 85% in Viola odorata, 82.81% Cannabis sativa and lowest (61.11%) in Withania somnifera. Moreover, reading the richness and diversity of the endophytic fungi, the highest was obtained for O. sanctum, W. somnifera and C. sativa having eight species each, while lowest (6 and 4) was obtained from A. vasica and V. odorata, respectively. As the role of endophytic organisms in defensive mechanisms of plants is now well established, the present study is an important step to find new and interesting endophytes among the medicinal plants. © 2013 Taylor & Francis.

Hemoglobin | Year: 2015

The concurrence of malaria and hemoglobinopathies, observed in malaria endemic regions, reflects the phenomenon of natural selection. Since the life cycle of the malaria parasite has an erythrocytic stage, abnormalities in the red blood cells (RBCs) hinder the parasite's survival in the human host. Hemoglobin (Hb) variants affect the life span of RBCs and thus lower the chance of infection by the parasite. While a change in just one of the Hb genes offers some protection against malaria, change in both alleles results in β-thalassemia major (β-TM). A striking geographical heterogeneity of β-thalassemia (β-thal) has been observed. Moving from Mexico in the west to China towards the east, the spectrum of mutations in the β-globin gene has been seen to vary. In the western end of the thalassemia belt, defects in the first intervening sequence (IVS-I) and exon 2 of the β-globin gene are more common, while on the eastern coast, IVS-II and exon 1 are also vulnerable to mutations. The worldwide increase in the incidence of β-TM mandates the need for efficient measures to reduce β-thal births, and the geographical heterogeneity of β-thal alleles reduces the burden of genetic testing of fetuses suspected of carrying a mutant allele. In the present review, the common mutations in the global thalassemia belt have been illustrated, and the possible factors that affect the mutagenicity of sites have been discussed. A biogeorgraphic analysis that may provide insight into the non biological factors influencing different loci in the β-globin gene in different geographical regions is suggested. © 2014 Informa Healthcare USA, Inc.

The present study describes the antifungal potential of fruit and powdered ingredients of triphala churna, i.e. Emblica officinalis (Garetn.) (Amla), Terminalia bellirica (Gaertn.) Roxb. (Baheda) and Terminalia chebula (Retz.) (Harada), collected from the market of Gwalior (M.P.), India. Water extracts of all the fruits and powdered samples were tested (in vitro) for their antifungal activities by poisoned food technique against different Aspergillus species (A. flavus, A. fumigatus, A. versicolor, A. terreus and A. niger) associated with them during storage. All extracts displayed varied levels i.e. very low to very high antifungal activities on four Aspergillus species. The aqueous extracts of fresh fruits (37.96 +/- 7.59%) was observed to be most effective than dry fruits (34.95 +/- 7.59%) and powder (25.07 +/- 6.05%). Terminalia chebula (fresh and dry) extracts were found most active against the four Aspergillus species with 49.15 and 40.8% inhibition, respectively. None of the extracts were found effective against the growth of A. niger. All fruits and powdered aqueous extracts were observed to be ineffective against the A. niger. The variability in antifungal activity of aqueous extracts in the present study may be useful to study the relationship between antifungal potential of herbal drugs and prevalence of fungal contaminant during their storage.
