Recreational waters should be considered as risks for Enterococcal infections in regions with high utilization and long exposure periods. The aim of this study was to investigate the resistance of Enterococci to selected antibiotics and some heavy metals [Pb+2, Fe+2, Zn+2 and Cr+2]. A total of 75 Enterococcal isolates was obtained from 54 bathing and ...

background: the bioavailability of metronidazole after oral ingestion, in ordinary conditions, is quite similar to intravenous administration of the drug.  however, the degree of its absorption is not known in the early periods after laparotomy.   objective:  to determine plasma levels of metronidazole in pediatric patients following elective abdominal surgery.   methods: the study group was co...

The susceptibilities of 87 periodontitis-associated strains of Actinobacillus actinomycetemcomitans to clarithromycin and erythromycin were determined by standard methodology recommended for Haemophilus influenzae. For clarithromycin the MIC at which 90% of the isolates were inhibited was </=2.0 microg/ml and the minimal bactericidal concentration at which 90% of the strains were killed was </=...

Eleven strains of nutritionally variant streptococci were tested for their susceptibility to penicillin by a broth dilution method. All minimal inhibitory concentrations were low. It was found that plates containing only vitamin B6 (pyridoxal HCl) and cysteine did not reveal true minimal bactericidal concentrations. When penicillinase was added to the subculture medium and a staphylococcal stre...

The activity of omiganan pentahydrochloride (formerly MBI 226; a synthetic cationic peptide) was assessed against 1,437 recent clinical bacterial isolates and 214 recent clinical yeast isolates. The omiganan was highly active, and minimal bactericidal concentrations or minimal fungicidal concentrations were either equal to or two- to fourfold higher than MICs. Kill curve experiments showed a cl...

Aromatic plants are rich in essential oils with considerable antimicrobial properties.The aim of this study was to investigate chemical composition, antimicrobial activity and antioxidant properties of Melissa officinalis and Deracocephalum moldavica essential oils (EOs). The identification of chemical constituents of the EOs was carried out using gas chromato-graphy-mass spec...
