Besides acting as antimicrobial compounds, dendrimers can be considered as agents that improve the therapeutic effectiveness of existing antibiotics. In this work we present a new approach to using amoxicillin (AMX) against reference strains of common Gram-negative pathogens, alone and in combination with poly(propylene imine) (PPI) dendrimers, or derivatives thereof, in which 100% of the avail...

In Canada, antimicrobial treatment is the most common approach for acute otitis media. The aim of the present study was to compare the cost effectiveness of treatment with amoxicillin versus a watch-and-wait approach (WAIT) within a Canadian pediatric setting. Four hundred eighty-eight children, six months to five years of age, who participated in a randomized controlled trial were included in ...

In the present position paper, an attempt was made to establish clinical breakpoints of amoxicillin to classify porcine respiratory tract pathogens as susceptible, intermediate or resistant based on their minimum inhibitory concentrations of amoxicillin. For this, a thorough review of the published literature with regard to swine-specific pharmacological data (including dosages of amoxicillin a...

The antibacterial susceptibility to frequently prescribed antibiotics of Streptococcus pneumoniae isolated from the pediatric patients with acute respiratory infectious diseases was investigated in a study of three medical institutions in Korea. Total 143 clinical isolates of S. pneumoniae were available for susceptibility tests between May 2003 and July 2007. Antimicrobial susceptibility data ...

CONTEXT The antibiotic susceptibility is the cornerstone for the eradication therapies of Helicobacter pylori. OBJECTIVES To evaluate the prevalence of primary resistance of H. pylori was evaluated in an urban Brazilian population. METHODS H. pylori isolates were obtained from patients submitted to an upper gastrointestinal endoscopy for the evaluation of dyspeptic symptoms. Biopsies from a...

BACKGROUND A vast number of Helicobacter pylori treatment trials have been conducted. Regimens may vary in efficacy in different patient populations. METHODS We identified sources of treatment effect variation from 618 treatment groups using weighted cross-classified multi-level meta-regression models. Summary effect estimates were calculated within groups that lacked identified heterogeneity...

Amoxicillin, which inspite of being effective is losing its importance due to less bioavailability. Bioavailability could be enhanced by combining the antibiotics with bioenhancers like Piperine and Ginger resin. The present abstract deals with the use of piperine and ginger resin in increasing the bioavailability of amoxicillin using the insitu SPIP method. Piperine, isolated was found to be 9...

Introduction: Enteric fever is a public health problem in developing countries including Nepal. Antimicrobial sensitivity pattern of Salmonella sp causing enteric fever is changing over time and also differs according to geographical location. Periodic surveillance of antimicrobial resistance of Salmonella sp is mandatory for management of enteric fever rationally. The objective of this study w...

OBJECTIVES Amoxicillin and clarithromycin have been proven to be effective in the treatment of community-acquired pneumonia. This study investigated the in vivo bactericidal efficacy of a novel, pulsatile dosing strategy for amoxicillin and clarithromycin, when used as monotherapy and combination therapy. METHODS A neutropenic murine pneumonia model was used to assess the bactericidal activit...

In enterococci, intrinsic low-level resistance to gentamicin does not abolish synergism with a cell wall-active antibiotic while high-level resistance due to acquired aminoglycoside-modifying enzymes does. To study the impact of intermediate levels of resistance to gentamicin (64 < MIC < 500 microg/ml), we selected in vitro three consecutive generations of mutants of Enterococcus faecalis JH2-2...
