Our objective was to characterize 46 unique, erythromycin-sensitive, and clindamycin-resistant Streptococcus agalactiae strains from S. Korea that displayed a novel phenotype in double-disk diffusion assay. We used polymerase chain reaction to determine presence of erythromycin and clindamycin resistance genes, disc diffusion assays to determine resistance phenotype, and microbroth dilution to ...

The antimicrobial potential of seventy-seven extracts from twenty-four plants was screened against eight bacteria and four pathogenic fungi, using microbroth dilution assay. Lowest concentration of the extract, which inhibits any visual microbial growth after treatment with p-iodonitrotetrazolium violet, was considered to be minimum inhibitory concentration (MIC). Water extracts of Acacia nilot...

background: calf diarrhea is an important disease that is caused by different pathogens including bacteria, virus and parasites and is associated with economic losses. objectives: in this study, we evaluated the antibacterial activities of zatacin (z. multiflora aerial part ethanol extract), colistin, co-trimoxazole and enrofloxacin against clinical isolates of salmonella sp, e. coli and campyl...

Case presentation: We report a rare case of fungal pericardial effusion caused by the recently recognized multidrug-resistant Candida auris, which was cultured from pericardial fluid, blood, bronchoalveolar lavage and urine of a chronic liver disease patient while on empiric fluconazole therapy. The yeast was misidentified as Candida haemulonii by the VITEK2 commercial identification system, an...

Background and aim: Satureja khuzestanica has numerous proven biological properties. This study was carried out to determine the amount of carvacrol in the industrial and laboratory essential oils of the wild and cultivated S. khuzestanica, and investigate their antibacterial properties. Methods: The essential oil of the cultivated S. khuzestanica was prepared industrially in the Khorraman Phar...

background and objectives : the rapid emergence and dissemination of carbapenemase-producing klebsiella pneumoniae strains and other members of the enterobacteriaceae poses a considerable threat to the care of hospitalized patients and to public health. the aim of this study was to determine the frequency of metallo-β-lactamases (mbl) and vim-1 gene in multidrug-resistant strains of k. pneumoni...

background: lactobacilli are known as a valuable sourceof antimicrobial compounds and have a high potential of use infood biopreservation against food related microorganisms.objectives: antimicrobial potency of 63 dairy lactobacilliisolates against four highly important food-related microorganismswere evaluated. in addition, a new way in data organization wasintroduced, which led to a more info...

Introduction The presence of linezolid-resistant enterococci found in animal-derived food has attracted attention for possible transmission to human-derived through the chain. Linezolid-resistant farms have been widely reported, but carrying antimicrobial resistance (AMR) genes poxtA , optrA or cfr (D) slaughterhouse environments not well addressed. Methods Enterococcus was isolated from sample...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...
