The newer fluoroquinolones are a possible alternative treatment option for S. maltophilia infections in this environment but further studies and clinical investigations are needed to determine the in vivo efficacy of these drugs.]]> Wed 12 May 2021 22:57:08 SAST ]]> In-vitro anti-vibrio activities of crude extracts of Garcinia Kola seeds https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11256 Wed 12 May 2021 22:23:09 SAST ]]> Bioactivity and phytochemical analysis of Hydnora Africana on some selected bacterial pathogens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11247 0.05). Qualitative phytochemical analysis confirmed the presence of alkaloids, saponins, steroids, tannins and flavonoids in the methanol, acetone,ethanol and ethyl acetate extracts. The results demonstrate that H. africana may contain compounds with therapeutic potentials which can be lead molecules for semi-synthesis of new drugs.]]> Wed 12 May 2021 19:43:31 SAST ]]> Assessment of the antibacterial properties of n-Hexane extract of Cocos Nucifera and its interactions with some conventional antibiotics https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11245 Wed 12 May 2021 19:18:43 SAST ]]> In vitro activity of bioactive compounds of selected South African medicinal plants on clinical isolates of Helicobacter pylori https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11255 Thu 13 May 2021 06:53:04 SAST ]]> Assessment of the anti-Listerial properties of Garcinia kola (Heckel) seeds https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11278 10 mg/ml for the aqueous extract. The minimum bactericidal concentration (MBC) ranges of the extracts were 0.625–10 mg/ml for both the n-hexane and the dichloromethane extract; 5-10 mg/ml for the methanol extract; and those for the aqueous extract were above 10 mg/ml against all the susceptible Listeria isolates. The rate of kill analysis was then determined for the three most active crude extracts that is excluding the aqueous extract and it was assessed against four representative Listeria species namely L. monocytogenes (LAL 8), L. grayi (LAL 15), L. ivanovii (LEL 30) and L. ivanovii (LEL 18). All the three extracts showed a general trend of being concentration and time dependent in their rate of kill profiles such that most bacteria cells were killed at the highest test concentration of 4× MIC value after the maximum exposure time of 2 h. The n-hexane, dichloromethane and methanol extracts were bactericidal against 4, 3 and 1 isolates out of the four test Listeria isolates respectively.]]> Thu 13 May 2021 06:09:04 SAST ]]> Phytochemical analysis and bioactivity of Garcinia Kola (Heckel) seeds on selected bacterial pathogens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11259 Thu 13 May 2021 03:10:48 SAST ]]> Phytochemical analysis and bioactivity of the stem bark of Combretum Molle on some selected bacterial pathogens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11261 0.05) in the potency of the xii four extracts (acetone, methanol, ethanol and ethyl acetate) and antibiotic (ciprofloxacin) on the different bacterial strains tested, likewise the crude extract and the fractions. No compound was detected by GC-MS whereas numerous peaks were identified by HPLC implying that the active compounds in this plant are non volatile. We could not identify the compounds thereby proposing further studies using Nuclear magnetic resonance to identify the compounds. The study revealed that the acetone extract of C. molle was the most active against all the test organisms and therefore justifies the use of this plant in traditional medicine.]]> Thu 13 May 2021 01:14:11 SAST ]]>
