Antibacterial and Anti HIV 1 Reverse Transcriptase Activity of Selected Medicinal Plants from Phalaborwa, South Africa

Conclusion: The findings of the study indicate that studies of this nature are useful and may lead to for discovery of more plant-derived compounds with activities against bacterial and viral strains. Furthermore, the identity of the active ingredients may be important to establish the mechanisms used by some of these plants.

This study evaluated the effect of a novel formulation for starter culture associated with specific ripening conditions (NoNit™ technology) vs. a commercial» starter on the fate of selected pathogens and hygiene indicators during the fermentation and ripening of experimentally spiked salame nostrano (Italian dry sausage). Selected strains of Staphylococcus aureus 27R, Escherichia coli CSH26 K 12, Listeria innocua ATCC 33090 and Salmonella Derby 27 were inoculated into salami batter and challenged with two formulations of starter cultures (a commercial formulation and the NoNit™ formulation, consisting of ...

Abstract The Aim of this study was to evaluate the effects of bacteriospermia on human sperm parameters, nuclear protamines, DNA integrity and ICSI outcome in patients enrolled for ICSI treatment. 84 unselected couples consulting in infertility and obstetrics clinic and enrolled for ICSI treatment were included in this study. The semen specimens were screened bacteriologically; semen and sperm parameters were also evaluated according to WHO guidelines. DNA integrity, protamines concentration and protamine deficiency were estimated by TUNEL assay, AU-PAGE and Chromomycin (CMA3) respectively. The results of this stu...

This study was conducted to evaluate their activities in vitro against five Gram-negative and five Gram-positive of clinically pathogenic bacterial strains and ten fungal strains. The antimicrobial activity was assessed, and the minimum inhibitory concentration values of the tested compounds were determined in μg ml−1, using the diffusion agar technique. The bacterial strains used were Escherichia coli (ATCC 25955), Proteus mirabilis (ATCC 7002), Klebsiella oxytoca (ATCC 700324), Pseudomonas aeruginosa (ATCC 10145), Enterobacter cloacae (ATCC 13047D-5), Bacillus subtilis (NRRL B-543), Enterococcus faecalis (RCMB 0...

The purpose of this study was to characterize mineral trioxide aggregates (MTA) enriched with iron disulfide (FeS2) nanostructures at different concentrations, and to investigate their storage modulus, radiopacity, setting time, pH, cytotoxicity, and antimicrobial activity. Iron disulfide nanostructures [with particle size of 0.357 ± 0.156 μm (mean ± SD)] at weight ratios of 0.2, 0.4, 0.6, 0.8, and 1.0 wt% were added to white MTA (wMTA). The radiopacity, rheological properties, setting time, and pH, as well as the cytotoxicity (assessed using the MTT assay) and antibacterial a...

Authors: Bondi M, Mazzini A, de Niederhäusern S, Iseppi R, Messi P Abstract The authors studied the in vitro antibacterial activity of the photo-activated porphyrin meso-tri(N-methyl-pyridyl), mono(N-tetradecyl-pyridyl)porphine (C14) against four multidrug-resistant bacteria: Staphylococcus aureus, Enterococcus faecalis (Gram-positive), Escherichia coli, Pseudomonas aeruginosa (Gram-negative). Using 10 μg/ml of porphyrin and 60 sec irradiation we observed the remarkable susceptibility of S. aureus and E. faecalis to treatment while, under the same conditions, E. coli and P. aeruginosa showed very low suscep...
