Bacterial antibiotic resistance is typically quantified by the minimum inhibitory concentration (MIC), which is defined as the minimal concentration of antibiotic that inhibits bacterial growth starting from a standard cell density. However, when antibiotic resistance is mediated by degradation, the collective inactivation of antibiotic by the bacterial population can cause the measured MIC to ...

The antibacterial effect of Lippia sidoides (rosemary pepper) essential oil was tested against the bacteria Staphylococcus aureus and Escherichia coli isolated from homemade Minas cheese produced in Brazil. The Minimum Inhibitory Concentration (MIC) determined in the Dilution Test was 13 L oil mL-1 for both bacteria, which characterizes inhibitory action in broth for a 24hour interaction perio...

The flavonoid apigenin was isolated from aerial part of P. oleracea L. The dried sample of plant was powdered and subjected to soxhlet extractor by adding 80 mL of ethanol : water (70 : 30). The extract was centrifuged at 11000 rpm for 30 min; supernatant was taken for further use. The fraction was concentrated and subjected to PTLC. The R f value of isolated apigenin was calculated (0.82). Pur...

OBJECTIVE To analyze the relationship between fluoroquinolone use at presentation and minimum inhibitory concentration in bacterial keratitis. METHODS The Steroids for Corneal Ulcers Trial was a randomized, double-masked, placebo-controlled trial assessing the effect of adjunctive topical corticosteroid treatment on outcomes in bacterial keratitis. After presentation, all patients were treate...

Cinnamon has been used for neuralgia on the knees and waist, and it is shown to have a wide antibacterial spectrum in both Gram-positive bacteria and Gram-negative bacteria. In this study, glucosyltransferase adhesive ability, acid-production suppression effect, and antibacterial activity were measured to identify the anti-caries effect of cinnamon extract. It was shown that cinnamon extract ef...

results ll-37 and its truncated analogs were effective in inhibiting the growth of pdrab and had a rapid killing ability. after exposure to the peptides, the development of the pdrab biofilm was inhibited. strong inhibitory and dispersion effects of ff/cap18 on the biofilm were confirmed by fluorescence microscopy and field emission scanning electron microscopy. conclusions this results show th...

background: the repetitive use of antibiotics in different fields (veterinary and medicine) improves the emergence and occurrence of the resistance phenomenon in pathogenic bacteria. due to the problem of antimicrobial resistance, it is an urgent need to discover new drugs and alternative treatments for the control of bacterial diseases in aquaculture. objectives: the purpose of this study is t...
