Antibiofilm activity of natural substances derived from plants

The main objective of this study was to conduct a review of bioactive substances derived from plants which show antimicrobial/antibiofilm properties. Vegetable species were widely employed as ingredients in medicine based on traditional knowledge. Various secondary metabolites have been proven to inhibit bacterial growth. Bacterial resistance mechanisms have increased over the years. Biofilms are types of bacterial...

Evaluation of semi-nested polymerase chain reaction (PCR) and mannan antigen detection compared to blood culture for diagnosis of candidemia

Invasive Candida infections have emerged as an important pathogen in the last decade, especially in immunocompromized patients. The aim of the present study was to evaluate the detection of Candida species in blood samples from pediatric patients with sepsis by blood culture method versus antigen detection method by enzyme linked immunosorbent assay (ELISA) and molecular method by polymerase chain reaction (PCR). This...

Effect of the fermentation on the microbial population occurring during the processing of zoom-koom, a traditional beverage in Burkina Faso

Zoom-koom is a traditional fermented beverage from Burkina Faso based on cereals such as millet or sorghum. Samples were collected from two local production sites of microenterprises (Zogona and Dassasgho). Microorganisms dynamic during the production of zoom-koom were enumerated using pour plate methods. The titratable acidity, pH and temperature of fermentation were determined using respectively titrimetric and...
