To study the existence of Clostridium septicum as probable agent associated with currently occurrence of black quarter in Urmia area, sheep-dung samples were collected. The bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in Clostridia genus include isolation and biochemical identification were performed. The results showed 28 different types ...
Background & Objectives: Staphylococcus aureus is one of the most common nosocomial pathogens with high mortality rates. The Biofilm-dependent methicillin-resistant S. aureus remains a major clinical concern in this group of patients. The aim of this study was to investigate the icaABCD forming biofilm genes in methicillin resistant isolates of S. aureus. Materials and Methods: In study was per...
This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...
Background and purpose: Invasive aspergillosis (IA) is a leading cause of morbidity and mortality in patients with decreased immune status. Aspergillus flavus is the second most common species causing invasive aspergillosis after A. fumigatus. According to limited information on the antifungal susceptibility test against A. flavus in Iran, in this study we aimed at evaluating the antifungal sus...
Introduction & Objective: Fluoroquinolones are essential antimicrobial agents used to treat UTIs. Clinical experiences have shown a high rate of antibiotic resistance among uropathogens. These resistance are usually the consequence of mutations involving genes encoding gyrA and parC. The aim of this study was to determine antimicrobial resistance pattern and the presence of mutations in regions...
Background and purpose: The aminoglycoside modifying enzymes (AMEs) and class 1 integrons in clinical isolates of pseudomonas aeruginosa are the major factors leading to rapid spread of antibiotic resistance. The aim of the present study was to investigate the frequency of aac(6)-IIa, ant(2'')-Ia, and class 1 integrons in clinical isolates of pseudomonas aeruginosa. Materials and methods: For ...
Abstract Background and Objective: CTX-M type extended spectrum beta-lactamases is a rapidly expanding group of enzymes encountered with increasing frequency, especially, in Escherichia coli (E. coli). There are a few reports on phylogenetic background of E. coli isolates from clinical sources of under five-year- old children in Iran. The purpose of this study was phylotyping of E. coli isola...
BACKGROUND The aim of our study was to investigate the possible etiology of avian colibacillosis by examining Escherichia coli isolates from fecal samples of healthy broilers. FINDINGS Seventy-eight E. coli isolates from fecal samples of healthy broilers in Japan were subjected to analysis of phylogenetic background, virulence-associated gene profiling, multi-locus sequence typing (MLST), and...
during 2001-2005, 79 isolates of rhizoctonia from seed rot, seedling damping –off, root rot and dry rot canker of sugar beet were collected. based on morphological characteristics, number of nuclei per cell and hyphal diameter, isolates were classified in two groups, binucleate (4 isolates) and multinucleate (75 isolates). among 75 multinucleate isolates ,27 isolates were identified as ag4, 28...
