Amiloride at millimolar concentrations caused marked changes in the growth-dependent intracellular balance of Na+ and K+ in Streptococcus faecalis. These results, whether specific to transport processes or resulting from indirect yet unknown mechanisms, constitute the first evidence of an effect of amiloride on bacterial electrolytes.

Background: Endodontic treatment aims in the preservation of extremely carious primary teeth. For root canal therapy to be successful, root canals must be properly prepared and effectively irrigated .Therefore, it is necessary to select the proper root canal disinfection method to preserve the primary tooth.

A phage-antibiotic synergy could be an alternative in urinary tract infection (UTI) therapy, as it leads to the elimination of bacteria and to the reduction in variants resistant to phages and antibiotics. The aims of the in vitro study were to determine whether phages vB_Efa29212_2e and vB_Efa29212_3e interact synergistically with selected antibiotics in the treatment of infections, to optimize antibiotic concentrations and phage titers for the most effective combinations, and to assess their impact on the number of spontaneous resistant variants and on the phages' reproductive cycles. The modified double-layer disc diffusion method, checkboard, time-kill assays, one-step growth method and the double agar overlay plaque assay were implemented.

Case Report: We report the case of a 63-year-old patient who underwent aortic valve replacement with a biological valve for a bicuspid aortic stenosis, and LIMA-IVA single-bypass surgery. Two weeks later, he presented with Enterococcus faecillis bacteremia, attributed to left pyelonephritis and successfully treated with Amoxicillin. Two months after his surgery, he had a new bacteremia due to Enterococcus faecalis and we discovered a pseudo-aneurysm of the mitro-aortic trigone.
