Antimicrobial activities of a novel biflavonoid and other constituents from Rhus natalensis
(Academic Journals, 2013)Phytochemical studies on Rhus natalensis root bark collected from Kenya led to the isolation and identification of a new biflavonoid (3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4-hydroxyphenyl)-1-oxopropan-2- yl)-7-methoxy-4H-ch ... -
Antimicrobial activity of two South African honeys produced from indigenous Leucospermum cordifolium and Erica species on selected micro-organisms
(BioMed Central, 2008)Background: Honey has been shown to have wound healing properties which can be ascribed to its antimicrobial activity. The antimicrobial activity can be effective against a broad spectrum of bacterial species especially ... -
Antimicrobial resistant Gram-positive cocci in pregnant mothers with aerobic vaginitis
(Infection Control Africa Network (ICAN), 2016)The vaginal microbiota of a healthy asymptomatic woman consists of an extensive diversity of anaerobic and aerobic bacterial genera and species dominated by the microaerophilic genus Lactobacillus , known to inhibit the ... -
Antimicrobial-resistant Klebsiella species isolated from free-range chicken samples in an informal settlement
