Objective: To compare the antibacterial activity of different solvent extract of Clavaria rosea. Method: Different solvent extract of Claveria rosea was prepared. Standard cultures of Escherichia coli (MTCC-1698), Klebsiella pneumoniae (MTCC-7028), Pseudomonas aeuroginosa (MTCC-1934), Salmonella typhi (MTCC-733), Xanthomonas campestris (MTCC-2286), Pseudomonas syringae (MTCC-1604) and Agrobacterium tumefaciens (MTCC-431), gram negative. Staphylococcus aureus (MTCC-902) and Streptomyces pneumoniae (MTCC-4734), gram positive were used for the study. The antibacterial tests used were the agar well plate method. Tetracycline and Ciprofloxacin was used as the positive control. Results: The chloroform and methanol extract of Claveria rosea does not show any activity against X. campestris, E. coli, S. typhi, P. aeuroginosa and P. syringae at all concentration in gram negative pathogens. Whereas petroleum ether extract cannot show against S. pneumoniae at all concentration in gram positive pathogens. However, the activity was less than the standard Tetracycline and Ciprofloxacin. The extract shows increasing inhibitory activity with increase in concentration (50%-100%). Conclusions: The use of natural products including medicinal mushrooms is increasing day by day and the...

This paper identifies and analyzes the determinants of public and private health care expenditure in Greece over the period 1970-2004 to assess its relationship with the lack of an integrated Primary Health Care System. The determinants assessed are those commonly stated in international literature as influencing health expenditure growth, i.e. per capita GDP-Gross Domestic Product- (income), demographic ageing and induced demand, expressed through the number of physicians. Several multiple linear regression models were developed and selected through stepwise entry and backward elimination. Dependent variables were per capita public and private health care expenditure. According to the results, the most important determinant, for both public and private health care expenditure, is population ageing. Per capita GDP is strongly and positively related to public health care expenditure, as well as to private health care expenditure, the latter, however, in a non-statistically significant form. The development of an Integrated Primary Health Care System in Greece has been constantly under discussion and review for the past two decades. Nonetheless, the lack of gatekeeping...

Infectious diseases are the second leading cause of death worldwide. The use and search for drugs and dietary supplements derived from plants have accelerated in recent years. The aim of this study was to evaluate the antifungal activities of the essential oils derived from some species of medicinal plants:Stachys pubescens, Coriandrum sativum, Cinnamomum zelanicum and Bupleurum falcatum against Fusarium oxysporum, Aspergillus flavus and Alternaria alternate. The essential oils were used to evaluate their MIC and MFC compared to the Amphotericin B as a reference antibiotic. Also the essential oils were analyzed by GC/MS. Results from the antifungal testing indicated that B. falcatum, S. pubescens and C. zelanicum essential oils showed high activities and inhibited the growth all of the selected fungi. While the essential oil of C. sativum displayed the moderate potential activity. The number of 6, 9, 15 and 22 components was identified in C. sativum, C. zelanicum, B. falcatum and S. pubescens respectively. These oils exhibited a valued potency, against the fungi. With consider of the result...

The antimicrobial activity of the individual extracts of Doliocarpus dentatus and Montricardia arborescens and combined extracts of both plants were investigated against bacterial strains E. coli, S. aureus and K. pneumoniae using the Disc/ Agar Diffusion method under asceptic conditions. The magnitude of the diameter of the zone of inhibition was used as an indication for antimicrobial susceptibility or potency. Aqueous and C2H5OH extract of Doliocarpus dentatus showed insignificant antimicrobial activities whereas the CH2Cl2 and EtOAC extract of Doliocarpus dentatus were antimicrobial. The area of zone of inhibition ranging from 68.3 mm2 to 89.4 mm2. However, all the extracts of Montricardia arborescens were antimicrobial against all three bacterial strains. The area of zone of inhibition ranging from 68.3 mm2 to 172.6 mm2. The combined extract also showed variation in potency against the three microbial strains with the area of zone of inhibition ranging from 180 mm2 to 368.6...

The present study explores the chemical composition, antimicrobial and antioxidant activities of sweet basil (Ocimum basilicum). Sweet basil essential oil was extracted using a Clevenger type apparatus. The oil yield of sweet basil was found to be 0.171%. A total of 75 compounds representing 99.9% of Sweet basil oil were identified. Linalool (69.85%) was identified as the major component present in sweet basil oil, followed by geraniol (10.850%), 1,8-cineole (6.430%), _ bergamotene (1.635%) and geranyl acetate (1.350%). sweet basil essential oil exhibited strong antibacterial activity against all the bacteria tested except Pseudomonas putida and Pseudomonas aeruginosa. The strongest inhibition activity of Sweet basil was observed against Streptococcus pneumoniae 2 (60 mm), Hemophilus influenzae (45 mm), Candida albicans (45 mm), S. pneumoniae 1 (37 mm) and Aspergillus niger (35 mm). Total antioxidants content quantified in Sweet basil essential oil using a commercial kit were found to be 50.32±1.8 mM. The essential oil extracted from Sweet basil was found to have higher linalool content, antimicrobial and antioxidant activities than most of...
