Background:Yersinia is a genus in the family Enterobacteriaceae that its species includeYersinia enterocolitica, Yersinia intermedia, Yersinia frederiksenii, and Yersinia kristensenii. Among these species, Yersinia enterocolitica is the most important one that causes various diseases such as gastroenteritis, mesenteric lymph...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.
In the last decades, Extended-Spectrum-β-Lactamases (ESBLs) in gram negative bacilli have appeared as a significant mechanism of resistance to antibiotics. Although resistance to carbapenems is increasing among bacteria, they are still the treatment of choice for serious infections caused by ESBL producers. Therefore, the aim of the present study was to evaluate the effect of ß-lacta...
cage birds like canaries can potentially harbor human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. considering many people's interests to keep canaries, present study was conducted in canaries from yazd to investigate the beta-lactam antibiotics resistant escherichia coli. 109 e. coli isolates from canary faeces in yazd were evaluated to...
The Advanced Expert System (AES) was used in conjunction with the VITEK 2 automated antimicrobial susceptibility test system to ascertain the beta-lactam phenotypes of 196 isolates of the family Enterobacteriaceae and the species Pseudomonas aeruginosa. These isolates represented a panel of strains that had been collected from laboratories worldwide and whose beta-lactam phenotypes had been cha...
The beta-lactam antibiotics are the most widely used of all the groups of antimicrobials, but beta-lactam resistance is increasingly common among members of the Bacteroides fragilis group. Three major mechanisms are involved in beta-lactam resistance, and they act together in certain instances. In the present study, 2 resistant mutants (238m and 1186m) of Bacteroides thetaiotaomicron, obtained ...
BACKGROUND Patients with a history of beta-lactam antibiotic allergy are often admitted to the hospital with severe or life-threatening infections requiring beta-lactam antibiotics. Strict avoidance of beta lactams to such patients may prevent them from getting adequate coverage and can lead to an increase in the use of alternative antibiotics, which can predispose to antibiotic resistance. Pas...
BACKGROUND Research suggests that 90% of patients labeled beta-lactam allergic are able to tolerate penicillins following further assessment. This study aims to define and describe the frequency of true beta-lactam allergy following allergy patient evaluation in a predominantly pediatric population. METHODS 306 primary care patients referred between January 2010 and June 2015 were assessed fo...
