to study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. the most frequently isolated organisms indecreasing order were: streptococcus spp., bacillus spp., staphylococcus spp., klebsiella spp., enterobacterspp. and escherichia coli followed by citrobacter spp., proteus spp. and pseudomo...

background and aims: herbal medicines are the major remedy in traditional medical systems and have a great contribution in maintaining human health and preventing many infectious diseases. the aim of this study was to assay antibacterial potential of marrubium vulgare l. extract against klebsiella pneumoniae resistant strains to current antibiotics and also gc/ms analysis to better understandin...

Background: Multidrug resistance and production of extended spectrum β-lactamases (ESBLs) by enteric gram-negative rods in hospitals and community continue to be worsened. We aimed to characterize the multidrug resistance and determine the prevalence of ESBL production by clinical isolates of Enterobacteriaceae in southeast Iran. Methods: Gram-negative bacteria isolated from clinical samples of...

Increasing resistance to antibacterials is a major public health problem. Antibacterial use is considered to be the main selective pressure driving this resistance, and the rate at which resistance develops has been shown to be associated with drug consumption. It has been suggested that reductions in the development of resistance will only result from significant changes in antibacterial use. ...

9-Propionylmaridomycin shows in vitro antibacterial activity against gram-positive bacteria and has some action on Neisseria gonorrhoeae and Vibrio cholerae, but is generally inactive against many gram-negative rods. This antibiotic exhibits strong activity against clinical isolates of Staphylococcus aureus which are highly resistant to erythromycin or oleandomycin, or both, but which are sensi...

Over the years, it has been a significant biochemical issue to understand the mechanism of drug resistance in most of the pathogens [1]. The resistances in some species of bacteria have been unfortunately developed to a level that no clinically available treatment is effective [2]. The mechanisms involved in the resistance may be depend upon the nature of antibiotics, its target sites, the bact...

The emergence of bacterial resistance to commercial antibiotics is an issue of global importance. During the last two decades, the number of antibacterial agents that have been discovered and introduced into the market has steadily declined and failed to meet the challenges posed by rapidly increasing resistance of the pathogens against common antibacterial drugs. The development of new classes...

Silver is considered as antibacterial agent with well-known mode of action and bacterial resistance against it is well described. The development of nanotechnology provided different methods for the modification of the chemical and physical structure of silver, which may increase its antibacterial potential. The physico-chemical properties of silver nanoparticles and their interaction with livi...

Objective To assess the application of antibacterial agents, alongside pathogen prevalence and Pseudomonas aeruginosa drug resistance, with the aim of understanding the impact of inappropriate antibacterial use. Methods This retrospective study assessed bacteria from wounds, catheters, blood, faeces, urine and sputum of hospitalized patients in burn wards between 2007 and 2014. The intensity of...
