Background and Objective: Gram-negative pathogens are considered the common cause of wound infections associated with increased mortality and morbidity rates. Antibiotics combination has been used to overcome this problem. Aims: In this study, we identify Gram-negative pathogens found in wound infections and assess the in-vitro efficacy of a combination of amikacin and imipenem against the resi...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
background and objective: uttarakhand region is less explored, but possess a great biodiversity. this diversity can be explored for isolation and characterization of new actinomycetes strains for seeking antimicrobial molecules. it can therefore be predicted that novel bioactive metabolite producing actinomycetes can be discovered to combat multidrug resistant bacterial pathogens. materials and...
background urinary tract infections (uti) caused by resistant bacteria are becoming more prevalent. the spread of extended-spectrum beta-lactamase (esbl)-producing bacteria worldwide has become a serious public health issue among healthcare centers and in the community. drugs and many secondary metabolites from medicinal plants have proved to be economical and effective against many pathogens. ...
the objectives of this study were to assess the microbiological quality of egyptian yoghurt and to investigate the antagonistic activity of some probiotic bacteria against some food borne pathogens in vitro and in yoghurt. the results indicated a poor microbiological quality of yoghurt, since the microbiological parameters recorded higher values than the admissible levels. results from the agar...
in recent years due to changes in lifestyle and eating behavior of the human populations, disease caused by contaminated food has increased significantly. listeria monocytogenes, escherichia coli o157:h7 and salmonella enteric are three of the most important food borne bacterial pathogens and can lead to food borne diseases. also today wide spread of resistance to antibiotics among bacteria occ...
Received: 14 April, 2009 Accepted: 21 Oct, 2009 Abstract Background & Aims: Antimicrobial resistance among bacterial pathogens is a worldwide problem. The selection of initial treatment is made on an empiric basis and susceptibility testing is important to modify empirical therapy, especially for treatment of common bacterial pathogens. The aim of the present study was to determine the antimi...
The study was undertaken to determine bacterial contamination of warm-water fish ponds and silver carps harvested from those ponds in Guilan province, Iran. In this respect, water samples were taken from 7 ponds and investigated by testing total bacteria, coliforms, and Escherichia coli. In addition, skin swab samples of silver carps caught from each pond were studied for enumeration of the sam...
