Intestinal bacteria were classified as gram-positive or gram-negative by an electrode system with a basal plane pyrolytic graphite electrode and a porous nitrocellulose membrane filter to trap bacteria. When the potential of the graphite electrode was run in the range of 0 to 1.0 V versus the saturated calomel electrode (SCE), gram-positive bacteria gave peak currents at 0.65 to 0.69 V versus t...
Cyanobacteria, the blue green algae are one of the most diverse groups of Gram-negative photosynthetic prokaryotes widely distributed throughout the world. Cyanobacteria are known to produce a wide range of secondary metabolites with various biological actions. The aim of this study was to test extracts from various cyanobacteria isolated from Geno hot spring, Bandar Abbas (Iran) against a dive...
Two different types of condensed tannins (CTs), which were extracted and purified from tilia (Tilia L.) black locust (Robinia pseudoacacia), studied tested against two kinds bacteria, including Gram-negative Gram-positive, avian pathogenic E. coli (APEC) Staphylococcus epidermidis (S. epidermidis) respectively, by minimal bactericidal concentrations (MBCs) scanning electron microscopy (SEM). Bo...
Introduction: Intertrigo is a common disease of the skin usually caused by fungi and/or bacteria, often involving major or minor skin folds.
