ABSTRACT
Objective: The objective of the present investigation was to perform the Gas Chromatography-mass spectrometry (GCMS) analysis of endophytic fungi Curvularia aeria MTCC-12847 isolated from Tribulus terrestris L. to find out the active compound present in the extract. Methods: The endophytic fungi were isolated from the plant Tribulus Terrestris L., leaf which was cultivated in optimized media for the production of secondary metabolites and was extracted using ethyl acetate. Ethyl acetate extract was used for the Gas Chromatography-mass spectrometry (GCMS) analysis. Results: GC-MS analysis of ethyl acetate extract of endophytic fungi revealed the presence of various secondary metabolites, the highest amount present was Palmitic acid (24.54%) and Lowest was Dimethyl 1-phenyl-7-methyl-1-hydroxy-1,4-dihydronaphthalene-2,3-dicarboxylate (5.76%). Conclusion: The endophytic fungal Curvularia aeria MTCC-12847 extract isolated from the Tribulus terrestris L. shows the presence of various bioactive compounds.
ABSTRACT
Objective: The objective of the present investigation was to find antimicrobial and MIC of endophytic fungi Fusarium sp. isolated from Tephrosia purpurea root. Methods: Well diffusion assay was performed to find out the antimicrobial activity and Resazurin dye reduction method was performed to find out MIC of the extract. Result: The extract showed the highest zone of inhibition of 22.66±0.57 mm, (Bacillus subtilis, MTCC-441) for Gram-positive bacteria and 20.66±0.57 mm, (E. coli, MTCC-443) for Gram-negative bacteria. Furthermore, the MIC of the extract was found to be (31.25 µg/ml-125 µg/ml). Conclusion: Hence, the endophytic fungi isolated from the Tephrosia purpurea root, i.e. Fusarium sp. showed good antimicrobial activity and hence can be used to find a novel drug.
ABSTRACT
A study was carried out to determine the prevalence and management of Human African Trypanosomiasis (HAT) in Urambo; Kasulu and Kibondo districts of western Tanzania. Parasitological surveys for trypanosome and other blood parasites were conducted in selected villages. Interviews with health workers were conducted to explore facility capacity to diagnose and manage HAT. Community knowledge on tsetse and availability of trypanocidal drugs was explored. Results showed that; although health facility records showed HAT is an important public health problem in the three districts; typanosomes were found in 0.6of the examined individuals in Urambo district only. Malaria parasites with a prevalence of 12.1; 19.7and 9.7; in Urambo; Kibondo and Kasulu; respectively were detected in blood samples from the same individuals examined for trypanosomes. There was poor capacity for most of the health facilities in the diagnosis; treatment and control of HAT. In both districts; communities were knowledgeable of the tsetse identity (82.4) and had experienced tsetse bites (94). The majority (91.4) of the community members knew that they were at risk of acquiring HAT. However; only 29of the respondents knew that anti-trypanocidal drugs were readily available free of charge from health care facilities. Late treatment seeking behaviour was common in Kasulu and Urambo districts. In conclusion; health facilities in western Tanzania are faced with problems of poor capacity to diagnose and manage HAT and that treatment seeking behaviour among the communities at risk is poor. Efforts should be made to strengthen the capacity of the health facility to handle HAT cases and health education to the population at risk
