Genotypic characterization of Escherichia coli strains isolated from dairy cattle environment

The aim of this study was to characterize the diversity of Escherichia coli strains involved in the dispersion of virulence genes. 152 E. coli strains originated from dairy cattle environment were evaluated through phenotypic and proteomic assays. These samples were investigated for the presence of virulence genes (eaeA, stxI, stxII, ST, LT, eagg, ial) and biofilm related genes (fimH, csgA, flu). Eighteen profiles were...

Phytochemical screening, toxicity and antimicrobial action of Solanum paniculatum Linn extract against dental biofilm bacteria

The aims of study were to determine the phytochemical composition of hydroalcoholic extract of Solanum paniculatum Linn (jurubeba) root, to evaluate its in vitro antimicrobial action, as well as to determine the acute toxicity and potential cytotoxic effects of this extract. The extract was characterized by phytochemical screening and thin-layer chromatography. The following oral bacteria were used to determine the...

Phytochemical screening and antifungal activity of leaves extracts of Luffa cylindrica (Roem)

Mycosis constitutes a common health problem, especially in developing countries like Nigeria. The current cascade of antifungals are either too toxic or require long term use for total eradication. This study evaluates antifungal activity and phytochemical constituents of Luffa cylindrica leaves extract which were screened for the presence of bioactive phytochemicals and extracted by cold maceration in n-hexane, ethyl...
