Widespread use of various antimicrobial agents resulted in the emergence of bacterial resistance. Mechanisms like direct efflux, formation, and sequestration of metals and drugs in complexes and antiporter pumps are some examples. This investigation aims to investigate the resistance pattern of penicillin-resistant bacterial strains to some physicochemical agents. Sensitivity/resistance pattern...

Background: Paenibacillus larvae is the etiological agent of American foulbrood (AFB) disease, the most lethal disease in honeybee (Apis mellifera) larvae. Aims: The aim of the present work was to study the antimicrobial effect of cell free supernatant (CFS) of probiotics on an Iranian isolate’s biofilm formation. Methods: A l...

context biocompatible polymers are potentially effective for dental infections as delivery carriers of disinfectants or antibiotics into the root canal system (rcs). this study aimed to review polymeric microspheres enabling a controlled release of endodontic medicaments. evidence acquisition a literature search was carried out in the pubmed database (may 2013) using the following keywords: “po...

Introduction: Bacterial meningitis is still one of the most dangerous infectious diseases and causes serious complications and mortalities in children. The aim of this study was to identify the most common of bacterial agents causing meningitis in children under 10 years old and to detect their resistance to antibiotics in patients who referred to the educational hospital of Hamadan. Materials...

The authors') studied previously on the in vitro combined effect of sulfisoxazole with antituberculous agents and reported that the effect consisted of the heterogeneous composition of bacterial population with regard to drug sensitivity and the retarding action of drugs on the generation time of the organism. This study concerned with the effect of sulfisoxazole with antituberculous agents inh...

The interest in bacterial biocontrol agents as biosustainable alternatives to pesticides increase crop yields has grown. To date, we have a broad knowledge of antimicrobial compounds, such DAPG, produced by bacteria growing the rhizosphere surrounding plant roots.

This study conducted at the Research Institute for Tropical Medicine from April 1990 to December 1992, identified the etiology of acute lower respiratory tract infection (ALRI) in 119 (36.9%) of 317 hospitalized children < 5 years of age. A higher proportion of respiratory viruses (27.2%) than bacterial agents (10.7%) were identified. Viral agents (adenovirus, RSV, parainfluenza 3, influenza A ...

Ascochyta blight is one of the most common diseases that threaten pea and cause severe crop losses. The research concerned with integrated control this disease by studying effect biological agents inorganic salts, planting dates distances, especially in light climate change impact these factors on spread disease. In study, two bacterial strains Bacillus megaterium Pseudomonas fluorescens as bio...

Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...
