background: urinary tract infection (uti) is one of the most prevalent infectious diseases and escherichia coli is its common cause. the aim of this study was to assess the resistance patterns of e.coli in urinary tract infections and to determine the susceptibility of e.coli to commonly used antimicrobials and also to evaluate the options for empirical treatment of uti. methods: this study was...

herbs have been used for its medicinal properties from several thousand years ago. herbs, essences and extracts, possess a variety level of biological activities and antimicrobial activities of a large number of them have been proved. eucalyptus is one of these plants which the anti-virus effects of its extract has long been used to treat influenza and colds in most parts of the world. the aim ...

introduction: pseudomonas aeruginosa is a serious challenge for antimicrobial therapy, due to chromosomal mutations or intrinsic resistance to various antimicrobial agents, such as metallo-β-lactams (mbl). this study aimed to investigate the prevalence of β-lactamases encoding genes among p. aeruginosa strains isolated from intensive care unit (icu) patients by phenotypic and multiplex pcr meth...

The accurate performance of the Vitek 2 GP67 card for detecting methicillin-resistant coagulase-negative staphylococci (CoNS) is not known. We prospectively determined the ability of the Vitek 2 GP67 card to accurately detect methicillin-resistant CoNS, with mecA PCR results used as the gold standard for a 4-month period in 2012. Included in the study were 240 consecutively collected nonduplica...

Essential oils (EOs) are vastly used as natural antibiotics in Complementary and Alternative Medicine (CAM). Their intrinsic chemical variability and synergisms/antagonisms between its components make difficult to ensure consistent effects through different batches. Our aim is to evaluate the use of artificial neural networks (ANNs) for the prediction of their antimicrobial activity. Methods. T...

The objective of the present study was to determine the frequency of Staphylococcus aureus nasal carriage among dialysis and kidney transplant patients, to identify the antimicrobial resistance profile of these strains and to verify their genetic profiles with the RW3A primer. The study included 159 individuals, comprising 111 dialysis and 48 kidney transplant patients. Of the 48 transplant pat...

A total of 24 strains of the Mycobacterium fortuitum complex were tested for susceptibility to antimicrobial agents by the disk diffusion and agar dilution techniques. By comparing zones of inhibition obtained with the disk diffusion technique with results of minimal inhibitory concentration determinations, it was shown that disk diffusion results could predict in vitro susceptibility to select...

The antimicrobial susceptibilities of 100 clinical isolates of Pseudomonas aeruginosa to six antipseudomonal antibiotics were tested by five methods: the National Committee for Clinical Laboratory Standards (NCCLS) methods for broth microdilution, agar dilution, and agar disk diffusion; the Vitek Automicrobic System method (Vitek Systems, Hazelwood, Mo.); and the PDM Epsilometer test (E test) (...
