Antimicrobial susceptibility testing before first-line treatment for infection in patients with dual or triple antibiotic resistance.

Aim: To evaluate the efficacy of antimicrobial susceptibility-guided therapy before first-line treatment for infection in patients with dual or triple antibiotic resistance.

Methods: A total of 1034 patients infected by () during 2013-2014 were tested for antimicrobial susceptibility. 157 of 1034 (15%) patients showed resistance to two (127/1034; 12%) and to three (30/1034; 3%) antibiotics.

Clarithromycin resistance in Helicobacter pylori and its molecular determinants in Northern Spain, 2013-2015.

Objectives: Clarithromycin resistance (CLR-R) is the main reason for failure of Helicobacter pylori infection treatment, which is frequently empirically prescribed due to the erroneous belief that culture for susceptibility testing is difficult. The aim of this study was to determine CLR-R in a region of southern Europe and to evaluate the utility of a PCR sequencing assay applied on gastroduodenal biopsies in detecting H. pylori and clarithromycin (CLR) susceptibility.

Clarithromycin for first-line treatment of Helicobacter pylori infection after culture in high-resistance regions.

Objective: Resistance to antibiotics is the major cause of treatment failure of Helicobacter pylori (HP) infection. The culture-guided triple therapy (chosen on the basis of a preliminary in-vitro susceptibility test) might help to increase treatment success in high antibiotic resistance regions. The aim of this study was to evaluate the effectiveness of treatment with clarithromycin in patients with clarithromycin-sensitive culture compared with patients treated empirically.

Regeneration of neuronal cell types in Schmidtea mediterranea: an immunohistochemical and expression study.

Freshwater planarians are unique in their ability to regenerate a complete Central Nervous System (CNS) from almost any small piece of their body in just a few days. The planarian CNS contains a pair of anterior cephalic ganglia lying on top of two ventral nerve cords that extend along the length of the animal. Studies of planarian CNS regeneration have generally used pan-neural markers, which provide only a general overview of the process.
