The alkaloids from the ethanolic extract of H. antidysenterica seeds were evaluated for their antibacterial activity against clinical isolates of enteropathogenic Escherichia coli (EPEC) in vitro, and their antidiarrhoeal activity on castor oil-induced diarrhoea in rats, in vivo. The plasmid DNA, whole cell lysate and outer membrane protein profile of a clinical isolate of EPEC was determined i...
We examined Escherichia coli and Klebsiella spp. from US hospitals for class 1 integrons. Of 320 isolates, 181 (57%) were positive; association of integrons with resistance varied by drug and organism. Thus, determining integron epidemiology will improve understanding of how antibacterial resistance determinants spread in the United States.
Background: Increasing bacterial infections as well as a rise in bacterial resistance call for the development of novel and safe antimicrobial agents without inducing bacterial resistance. Nanoparticles (NPs) present some advantages in treating bacterial infections and provide an alternative strategy to discover new antibiotics. Here, we report the development of novel self-assembled fluorescen...
background and objective: organisms producing ctx-m β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. however, the laboratory detection of these strains is not well defined. in this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of ctx-m β-lactama...
Due to the increasing emergence of drug resistant Tuberculosis (TB), particularly multidrug resistant TB (MDR-TB), extensive-drug resistant TB (XDR-TB) and also the development of resistance in the micro-organisms against available drugs there is a need to develop new, potent, fast-acting antibacterial and antitubercular drugs with low toxicity. With this aim different extracts of Phaseolus vul...
Drug resistance of bacterial pathogens is a growing problem that can be addressed through the discovery of compounds with novel mechanisms of antibacterial activity. Natural products, including plant phenolic compounds, are one source of diverse chemical structures that could inhibit bacteria through novel mechanisms. However, evaluating novel antibacterial mechanisms of action can be difficult...
Introduction: Considering growing increase of antibacterial resistance to antibiotics and existing of anti-bacterial compounds in plants, in this study the antibacterial effect of aqueous and methanol extracts of Allium jesdianum plant on some species of pathogenic bacteria was evaluated. Methods: In this experimental study, the aqueous and methanol extracts of Allium jesdianum plant were pr...
Knowledge of medicinal plants is often the only therapeutic resource of many communities and ethnic groups. "Erva-baleeira", Cordia verbenacea DC., is one of the species of plants currently exploited for the purpose of producing a phytotherapeutic product extracted from its leaves. In Brazil, its major distribution is in the region of the Atlantic Forest and similar vegetation. The crude extrac...
