Antimicrobial activity of several Brazilian medicinal plants against phytopathogenic bacteria

What is currently raised as a new approach in the management of plant diseases is the development and formulation of plant based biopesticides. The objective of present study is to evaluate the antibacterial activity of aqueous extracts of twelve species belonging to seven families collected from the Northeast of Brazil against four economically important phytopathogenic bacteria. Antibacterial activities of the aqueous...

Bacteriological quality and metal levels of boreholes and hand-dug well within the Golden Star Wassa mining areas in Ghana

This study seeks to assess the bacteriological, physicochemical and some trace metals levels in water samples from seven boreholes and a hand-dug well within communities of Golden Star Wassa Mine Limited in Ghana. Five of the sampling sites were slightly acidic and were below the lower limit of the acceptable World Health Organization (WHO) and Ghana Standard Authority (GSA) permissible guidelines for pH. However,...

Studies on leukocidins toxins and antimicrobial resistance in Staphylococcus aureus isolated from various clinical sources

Staphylococcus aureus toxins represent a public health challenge all over the world. This study aims to analyze the prevalence of genes encoding the staphylococcal leukocidins and their correlation with antimicrobial susceptibility and the source of isolation. For this purpose, the susceptibility of 75 S. aureus isolates to 12 antimicrobial agents was investigated. The leukocidins genes (lukD, lukE, lukF and lukS) were...

Endophytic microorganisms from Bauhinia monandra leaves: Isolation, antimicrobial activities and interaction with galactose-specific lectin BmoLL

Bauhinia monandra leaves are well known hypoglycemic agent in Brazilian popular medicine from which a galactose specific lectin (BmoLL) has been purified in milligram quantities. In this work, the antimicrobial activity of endophytes isolated from B. monandra leaves and the ability of BmoLL to agglutinate the microorganisms were evaluated. After disinfection, leaves of B. monandra were fragmented and distributed in...
