introduction: extended spectrum beta-lactamase (esbl) producing escherichia coli generate a major problem for clinical therapeutics and epidemiological study. the incidence of esbl producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. the aim of this study was to determine the a...

conclusions the present study reports on a high rate of multi-drug resistance, the predominance of the frequency of class 1 integron, and the emergence of spa type t790 among iranian staphylococcus aureus strains. the results revealed that the dissemination of multi-drug resistance among staphylococcus aureus isolates may be associated with the presence of integrons. therefore, continuous surve...

abstract       background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates.     methods: in this descriptive study, 120 enterococcus isolates ...

objective(s):   the ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. the perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. lichens are known prolific sources ...

background: in order to deworm the ruminants especially of sheep in iran, consumption of benzimi­dazoles has more than 2 decades history and today farmers are using imidazothiazoles, macrocyclic lactones and mostly benzimidazole compounds (bzs) to treat infected farm animals. it has been demonstrated that the most common molecular mechanism leading to bzsresistance in haemonchus contortus is a ...

conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...

the increasing incidence of multi drug resistance tuberculosis (mdr-tb) and extensively drug resistance tb (xdr-tb) worldwide highlight the urgent need to search for newer anti-tuberculosis compounds. it has been determined that pharmaceutical plant, hops ( humulus lupulus ), possesses some antibacterial effect. in this study, the antimycobacterial effect of this plant on rifampin sensitive and...
