Background/Aims: Fecal microbiota transplantation (FMT) is a highly effective therapy for refractory and recurrent Clostridium difficile infection (CDI). Despite its excellent efficacy and recent widespread use, FMT has not been widely used in South Korea thus far. We describe our experience with FMT to treat refractory/recurrent CDI. Methods: We conducted a chart review of patients who underwent FMT for refractory/recurrent CDI at Inha University Hospital, between March 2014 and June 2016...

Antimicrobial resistance (AMR) in general poses a threat to the sustainability of modern healthcare, but a particularly urgent and serious threat is posed by a specific group of antibiotic-resistant bacteria known as carbapenemase-producing Enterobacteriaceae (CPE). CPE are resistant to nearly all antibiotics and include common pathogens such as Escherichia coli and Klebsiella pneumoniae. In New Zealand, the incidence of CPE has increased from three isolates in 2012 to 45 in 2016. The current epidemiology of CPE in New Zealand has similarities with the extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) epidemic in the early 2000s (just before ESBL-PE underwent a non-linear increase in incidence)...

Floyd A Beckford, Kelsey R Webb
A series of four thiosemicarbazones from 6-nitropiperonal along with the corresponding copper complexes were synthesized. The biophysical characteristics of the complexes were investigated by the binding to DNA and human serum albumin. The binding to DNA is moderate; the binding constants run from (0.49-7.50)×10(4)M(-1). In relation to HSA, the complexes interact strongly with binding constants on the order of 10(5)M(-1). The complexes also display antioxidant behavior as determined by the ability to scavenge diphenylpicrylhydrazyl (dpph) and nitric oxide radicals...

REVIEW
María Guadalupe García-Patiño, Rodolfo García-Contreras, Paula Licona-Limón
Acinetobacter baumannii is the etiologic agent of a wide range of nosocomial infections, including pneumonia, bacteremia, and skin infections. Over the last 45 years, an alarming increase in the antibiotic resistance of this opportunistic microorganism has been reported, a situation that hinders effective treatments. In order to develop effective therapies against A. baumannii it is crucial to understand the basis of host-bacterium interactions, especially those concerning the immune response of the host...

BACKGROUND: Against a background of rapid increase of β-lactamase-producing or multi-resistant pathogenic bacteria and the resulting lack of effective antibiotic treatment, some older antibiotics have been tested for new therapeutic uses. One of these is fosfomycin, to which according to studies these resistant bacteria are very sensitive. Our study was designed because there is no data on the fosfomycin susceptibility rate in the Czech Republic. METHOD: In this study from January 2013 to June 2014 3295 unique isolates of Gram-negative bacteria which had caused urinary tract infections were examined...

Bacterial meningitis has become a global concern, because of the emergence of antibiotic-resistant bacteria. It has been demonstrated that liposomes can enter bacteria, thus providing a possible treatment for numerous infections, including meningitis. Fusogenic liposomes are pH-sensitive with a high capacity to fuse with the bacteria membrane and promote intracellular drug release. Moreover, this ability can be improved by using cell-penetrating peptides (such as Tat47-57, which is a peptide derived from the Tat protein of HIV)...

Although many methodologies have been developed to identify unknown bacteria, bacterial identification in clinical microbiology remains a complex and time-consuming procedure. To address this problem, we developed a label-free method for rapidly identifying clinically relevant multilocus sequencing typing-verified quinolone-resistant Klebsiella pneumoniae strains. We also applied the method to identify three strains from colony samples, ATCC70063 (control), ST11 and ST15; these are the prevalent quinolone-resistant K...
