Triclosan is the active ingredient in a multitude of health care and consumer products with germicidal properties, which have flooded the market in recent years in response to the public's fear of communicable bacteria. Although originally thought to kill bacteria by attacking multiple cellular targets, triclosan was recently shown to target a specific bacterial fatty acid biosynthetic enzyme, ...

In recent years, fabrication of metal oxide nanoparticles is intensively gaining the interest of various chemists as well as biochemist due to their applications in different fields. Among all the transition metal oxides, CuO and ZnO are the important metal oxide nanoparticles exhibiting tremendous properties and a wide range of applications. Both CuO and ZnO nanoparticles were prepared by comb...

Because of access to 16S rDNA sequencing, changes in the taxonomy and nomenclature of anaerobic gram-negative bacteria have occurred lately. New genera and species have been described, and existing taxa have been reclassified. The present article compiles a list of clinically relevant anaerobes and provides synonyms as well as the old nomenclature used for these bacteria. Although names and cla...

Overseas travel, as a risk factor for the acquisition of infections due to antimicrobial-resistant organisms, has recently been linked to carbapenemase-producing Gram-negative bacteria. Multiresistant Klebsiella pneumoniae, Escherichia coli, and Acinetobacter baumannii strains were isolated from a wound of a Canadian patient with a recent history of hospitalization in India. This resulted in th...

Graphene and related materials (GRMs) have been reported to extensive applications in many areas. The widespread use of GRMs makes them inevitably enter the environment through various links causing adverse effects on organisms. Bacteria were representatively used review toxicological biological organisms this paper. We comprehensively summarize recent researches about negative bacteria. This i...

Over the past 50 years the aetiology of purulent pericarditis has changed. Most cases used to be caused by Gram positive bacteria, but now there is a higher incidence of cases due to Gram negative bacteria and fungi.' Anaerobes are rarely found.' In the following case Bacteroides melaninogenicus, an anaerobic Gram negative bacillus, caused a purulent pericarditis secondary to a perforating tera...
