Abstract
Background: Heavy metals such as lead are considered a toxicant that can cause multiple organ complications including cancer, liver disease, renal diseases, neurodegenerative diseases, and reproductive diseases. In pursuit of a low-cost and easily accessible antidote, this research examined the role of Pericopsis laxiflora extract in acute lead poisoning in Sprague-Dawley rats.
Methods: Liver damage was caused in animal studies by inducing lead acetate (50 mg/kg daily, intraperit...

Botanicals from the flowers of Vernonia calvoana and the leaves of Senna spectabilis showed anti-Klebsiella activity and potentiated the activity of antibiotics against multidrug-resistant phenotypes overexpressing efflux pumps
Abstract
Background: The alarming trend of infectious diseases in public health is mainly due to bacterial multidrug resistance, the emergence of which is partly caused by the inappropriate use of antibiotics. Bacteria of the Klebsiella genus have acquired a priority level of resistance to antibiotics, reducing their effectiveness. The aim of this study was to evaluate the anti-Klebsiella activity of methanol extracts of Vernonia calvoana flowers and Senna spectabilis leaves against multidru...

Protective effect of hydroethanolic leaves extract of Solanum macrocarpon on Cisplatin-induced kidney injury in rats
Abstract
Background: Nephrotoxicity is a common kidney condition affecting many people worldwide, with conventional synthetic drugs not often yielding desirable results. This study, therefore, aimed to assess the protective effect of Solanum macrocarpon on Cisplatin-induced nephrotoxicity in Wistar rats.
Methods: Hydroethanolic extract of the leaves of S. macrocarpon was prepared and analyzed for basic phytochemical constituents. Cisplatin (5 mg/kg) was administered to induce nephrotoxici...

Antibacterial and antibiotic-potentiation activities of methanol extracts from Blighia sapida K. D. Koenig (Sapindaceae) against Gram-negative multidrug-resistant bacteria overexpressing efflux pumps
Abstract
Background: The emergence and spread of multidrug-resistant (MDR) Gram-negative bacteria, particularly those overexpressing efflux pumps, make treatment difficult using conventional antibiotics. This study aims to assess the antibacterial activity of methanol extracts (botanicals) from the leaves (BSL) and bark (BSB) of Blighia sapida against a panel of MDR bacteria that overexpress efflux pumps.
Methods: Phytochemical screening of botanicals was carried out using standard qualit...

Unveiling the anti-Klebsiella activity of methanol extracts from Hallea ciliata leaves and barks against multidrug-resistant strains overexpressing AcrAB-TolC efflux pumps
Abstract
Background: Infectious diseases are considered one of the most critical threats to public health. The present work aimed to determine the anti-Klebsiella activity of methanol extracts (botanicals) of Hallea ciliata leaves (HCL) and bark (HCB) against multidrug-resistant phenotypes over-expressing ACrAB-TolC efflux pumps.
Methods: The antibacterial activity of botanicals alone and in combination with PAβN and antibiotics, was determined using the broth microdilution method. The ef...

Antibacterial activity and antibiotic-potentiating effects of methanol extracts from Ocimum basilicum and Sarcocephalus latifolius against multidrug-resistant Gram-negative bacteria overexpressing efflux pumps
Abstract
Background: The inappropriate use of antibiotics against bacterial infections leads to increased bacterial drug resistance. In the present study, the effectiveness of methanol extracts from the leaves and flowers of Ocimum basilicum and the roots of Sarcocephalus latifolius against multidrug-resistant (MDR) Gram-negative bacteria overexpressing efflux pumps was assessed.
Methods: The antibacterial properties of crude extracts (botanical, with and without phenylalanine arginine β-...

Antibacterial activity of Sarcocephalus latifolius and Acacia sieberiana, and the effect of their association with antibiotics against multidrug-resistant Staphylococcus aureus
Abstract
Background: Infectious diseases continue to wreak havoc around the world causing directly or indirectly 17 million deaths per year. The present study was carried out to evaluate the in vitro antibacterial activity of the methanol extracts from the root of Sarcocephalus latifolius and from the leaves of Acacia siberiana, and their ability to potentiate the action of antibiotics against multidrug-resistant (MDR) Staphylococcus aureus.
Methods: The antibacterial assays were performe...

Ethnopharmacology and anthelmintic screening of some plants used in traditional medicine in the Far-North of Cameroon
Background: The use of traditional medicinal plants in Cameroon for the treatment of intestinal helminthiasis is a common practice among traditional healers and livestock breeders. However, the use of ethnopharmaceutical products for their anthelmintic activities against Haemonchus contortus has been poorly addressed in the Far-North region of Cameroon, therefore justifying the need to bridge this gap.
Methods: An ethno-pharmacological survey was conducted among livestock breeders and traditi...

The best African plant-derived antibacterial products for clinical perspectives: The state-of-the-art
Abstract
Background: The global burden of bacterial infections remains a serious health concern. In the present review, we have summarized the best botanicals and phytochemicals from the flora of Africa that deserve clinical studies to develop novel antibacterial drugs to combat enterobacteria, Pseudomonas aeruginosa, Gram-positive bacteria, and mycobacteria.
Methods: Data were retrieved from scientific databases such as PubMed, Scopus, ScienceDirect, Google Scholar, and Web of Science us...

Chemical constituents of Palisota ambigua (Commelinaceae) with their antibacterial activities
Background: The development and spread of resistance by bacteria to existing antibiotics are becoming more common nowadays. Considering the ethnopharmacological relevance of Palisota ambigua (Commelinaceae), this study was designed to investigate the antibacterial activities of chemical constituents of P. ambigua against two Gram-positive (Staphylococcus aureus ATCC 25923 and Streptococcus pneumoniae ATCC 49619) and two Gram-negative (Escherichia coli ATCC 8739 and Klebsiella pneumoniae 109 (iso...
