The antimicrobial activity of kanamycin, kanendomycin, gentamicin, amikacin, sisomicin, and dibekacin against 200 strains of Pseudomonas aeruginosa was compared. Dibekacin was found to be the most active against the tested organisms, whereas the other aminoglycoside antibiotics fell in the following order of diminishing antibacterial potency: amikacin, sisomicin, gentamicin, kanendomycin, and k...

With currently recommended disk susceptibility tests, minimal inhibitory concentration correlates for amikacin were greater than 16 micrograms/ml for resistance and less than or equal to 12 micrograms/ml (not less than or equal to 8 micrograms/ml) for susceptibility. For gentamicin, they were greater than 8 micrograms/ml for resistance and less than or equal to 6 micrograms/ml (not less than or...

Minimal inhibitory concentration determinations and disk diffusion and Autobac 1 susceptibility tests were performed on 22 strains of Aeromonas hydrophila. Eleven of the strains had discrepancies between Autobac and disk diffusion or minimal inhibitory concentration results. These discrepancies occurred with the beta-lactam antibiotics, primarily carbenicillin and cephalothin. It is recommended...

The in vitro activities of five quinolinecarboxylic acids against two laboratory strains of Chlamydia trachomatis were compared. The minimal inhibitory concentrations of nalidixic acid, cinoxacin, and pipemidic acid were all greater than or equal to 50 micrograms/ml; the activity of norfloxacin was intermediate (minimal inhibitory concentration, 8 to 16 micrograms/ml). Ciprofloxacin was the mos...

antimicrobial activity of the roots of eranthemum roseum (vahl) r.br. (dasmuli), were tested against different bacteria (including escherichia coli, staphylococcus aureus, bacillus subtilis, shigella sonnei, klebsiella pneumoniae, salmonella typhi, proteus vulgaris, pseudomonas aeruginosa) and fungi (such as candida albicans and aspergillus niger) by cup plate diffusion method. minimal inhibito...

INTRODUCTION Minimal hepatic encephalopathy refers to a mild neurocognitive impairment not detectable by clinical examination that can be present in cirrhotic patients. AIM To determine the prevalence of minimal hepatic encephalopathy in a secondary healthcare center in Northern Portugal. MATERIAL AND METHODS A cross-sectional study was conducted. Cirrhotic outpatients were included. EXCL...

In the present work, palygorskite (Pal) was initially subjected to an ion-exchange reaction with silver ions (Pal-Ag(+)). Subsequently, Ag-Pal nanocomposites were assembled by a convenient ultraviolet irradiation technique, using carbon dots (CDs) derived from wool fiber as the reducing agent. The obtained nanocomposites were characterized by powder X-ray diffraction (XRD), ultraviolet-visible ...

Acidic electrolyzed water (AEW), known to have germicidal activity, was obtained after electrolysis of 0.045% aqueous solution of sodium chloride. Freshly prepared AEW (pH 2.3-2.6, oxidation-reduction potential 1007-1025 mV, and free active chlorine concentration 27-35 ppm) was tested in vitro and (or) on tomato foliage and seed surfaces for its effects on the viability of plant pathogen propag...

Plant polyphenols are known to have varying antimicrobial potencies, including direct antibacterial activity, synergism with antibiotics and suppression of bacterial virulence. We performed the in vitro oligomerization of resveratrol catalyzed by soybean peroxidase, and the two isomers (resveratrol-trans-dihydrodimer and pallidol) produced were tested for antimicrobial activity. The resveratrol...
