purpose: in this study the inhibitory effect of eucalyptus extracts as a natural and herbal antibacterial substance was evaluated against pseudomonas aeruginosa strains (8821m and atcc27853). material and methods: the mic (minimal inhibitory concentration) of alcoholic and aquatic extracts of eucalyptus was determined using the tube and agar dilution methods. the growth rate of pseudomonas aer...

Abstract Antibiotics released into the environment at low (sub-inhibitory) concentrations could select for antibiotic resistance that might disseminate to human microbiome. In this case, low-level anthropogenic sources of antibiotics would have a significant impact on health risk. order provide data necessary evaluation risk, we implemented river water microcosms both sub-inhibitory and inhibit...

It has been proposed that sub-inhibitory concentrations of antibiotics play a role in virulence modulation. In this study, we evaluated the ability of Salmonella enterica serovar Typhimurium (hereafter S. Typhimurium) to colonize systemically BALB/c mice after exposure to a sub-inhibitory concentration of cefotaxime (CTX). In vivo competition assays showed a fivefold increase in systemic coloni...

the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

background and objectives: sub-minimum inhibitory concentration (s-mic) can induce changes in morphology, virulence factors and biochemical properties ofbacterial pathogens. the goal of this study is to determine the sub-mic effect of ciprofloxacin and ampicillin on the haemotytic activity of e. coli. material and methods:two clinical isolates of e. coli with high heamolytic activity was select...

Soccer players are required to anticipate and react continuously in a changing, relatively unpredictable situation in the field. Cognitive functions might be important to be successful in soccer. The current study investigated the relationship between cognitive functions and performance level in elite and sub-elite youth soccer players aged 13-17 years. A total of 47 elite youth soccer players ...

BACKGROUND/AIMS Motility is a feature of many pathogens that contributes to the migration and dispersion of the infectious agent. Whether gentamycin has a post-antibiotic effect (PAE) on the swarming and swimming motility of Escherichia coli (E. coli) remains unknown. In this study, we aimed to examine whether short-term pretreatment of sub-inhibitory concentrations of gentamycin alter motility...

Objective(s): Bidens species are used for their antidiabetic properties traditionally in many countries. Aim of this study is to evaluate hypoglycaemic and antidiabetic activity of Bidens tripartita extract and to identify its active compounds through bioactivity guided isolation technique. Materials and Methods: Hypoglycaemic effects of B. tripartita extract and its sub-extracts were investig...
