Background and Aim: Since the first description of Amebiasis, we still do not have a proper answer to the question of why disease and symptoms develop in only 5 to 10% of those infected with E. histolytica. It has been speculated that a spectrum of virulence levels among the E. histolytica strains contribute to the outcome of amebic infection. In this study, beside determination of prevalence r...
در بهار سال 1392 در باغ¬های به منطقه شهربابک واقع در 230 کیلومتری غرب استان کرمان، علائمی شبیه به آتشک برروی در ختان به در مرحله گلدهی و میوه نارس مشاهده گردید. نمونه¬ها از شاخه¬های جوان بیمار و میوه¬ها انتخاب گردید. باکتری¬ها با شستشوی بافت¬ها و کشت در محیط نوترینت آگار جداسازی گردید. به وسیله کشت مجدد بر روی محیط کشت پرگنه¬هایی که مورفولوژی شبیه erwinia amylovoraداشتند، خالص سازی گردید. ابتدا...
The H30 strain of Escherichia coli sequence type 131 (ST131-H30) is a recently emerged, globally disseminated lineage associated with fluoroquinolone resistance and, via its H30Rx subclone, the CTX-M-15 extended-spectrum beta-lactamase (ESBL). Here, we studied the clonal background and resistance characteristics of 109 consecutive recent E. coli clinical isolates (2015) and 41 historical ESBL-p...
background and objectives: e. coli and klebsiella spp. are recognized as most prevalent bacteria causing urinary tract infection (uti), the most common bacterial infection. decreasing of antimicrobial susceptibility in urinary pathogens has made difficulty in treatment of uti. the aim of this study was to determine antibiotic susceptibility of e. coli and klebsiella spp. isolated from urine of ...
AIMS The three main aims of the study were the assessment of the genetic relationship between a deviating Erwinia amylovora strain isolated from Amelanchier sp. (Maloideae) grown in Canada and other strains from Maloideae and Rosoideae, the investigation of the variability of the PstI fragment of the pEA29 plasmid using restriction fragment length polymorphism (RFLP) analysis and the determinat...
b ackg r oun d : pseudomonas aeruginosa is one of the most important oppor- tunistic pathogens responsible for various types of infections. children suffer significant morbidity and mortality due to nosocomial infections. the aim of this study was to investigate the presence of class1 integron, blabel, blaper, blakpc, blavim, blaimp and blaoxagroup-1 genes among p. aeruginosa isolates at child...
Objective(s): Prompt detection of extended-spectrum β-lactamases (ESBL) and carbapenemase-producing enterobacteriaceae is crucial for infection prevention and control strategies. The present study aimed to characterize the ESBL and carbapenemase genes among Enterobacter isolates from an Iranian inpatient population.Materials and Methods:...
ABSTRACT Fire blight of apple and pear is initiated by epiphytic populations of Erwinia amylovora on flower stigmas. Predicting this disease and managing it with microbial antagonists depends on an understanding of bacterial colonization on stigmas. Detached 'Manchurian' crab apple flowers were inoculated with E. amylovora and subjected to a range of constant temperatures or various fluctuating...
