استرپتومایسسها (streptomyces )از جمله باکتریهای گرم مثبت خاکزی هستند که در راسته اکتینومایسیته ( actinomycetes ) قرار دارند. این باکتریها کاربردهای بیشماری دارند و اشکال استفاده از آنها در پزشکی، کشاورزی، جنگل وبیوتکنولوژی بسیار گسترده است بطوریکه نیمی از آنتی بیوتیک های مصرفی و تولیدی جهان از استرپتومایسس ها بدست می آید با این وجود شرایط اقلیمی متفاوت ایران که می تواند گونه های بسیاری از است...
background: colibacillosis is one of the most economically important diseases of poultry worldwide. objectives: this study was conducted to examine the clonal relatedness and typing of 95 avian escherichia coli isolates by eric-pcr. methods: sixty-three e. coli isolates from two common manifestations of colibacillosis (yolk sac infection and colisepticemia) and 32 isolates from feces of apparen...
Introduction: Salmonella is one of the most important causes of gastroenteritis in humans. Salmonella enterica Serovar Typhimurium has many hosts in addition to humans, and its prevalence in the community is high. The aim of the study was comparing the genetic diversity of Salmonella enterica serovar Typhimurium isolated from human fecal samples by both of ERIC-PCR and BOX-PCR method. Methods:...
مطالعه ای برای تعیین سروتیپ ها و الگوی مقاومت ضد میکروبی در میان جدایه های سالمونلا در گاوها و گوساله های سالم، بیمار و کالبدگشایی شده انجام شد. در بررسی های قبلی نوزده جدایه ی سالمونلا از مدفوع و بافت های حیوانات مبتلا به سالمونلوز در دو گاوداری صنعتی در شمال شرق ایران حاصل گردیده بود. در قسمت دوم مطالعه، از هریک از دو گاوداری، 4 مرتبه نمونه گیری با فواصلِ 2 ماهه انجام شد. این نمونه ها شامل مدف...
The aim of this study was to evaluate the Enterobacterial Repetitive Intergenic Consensus (ERIC-PCR) as a tool for molecular typing of C. pseudotuberculosis isolates from eight different hosts in twelve countries. Ninety-nine C. pseudotuberculosis field strains, one type strain (ATCC 19410T) and one vaccine strain (1002) were fingerprinted using the ERIC-1R and ERIC-2 primers, and the ERIC-1R+E...
Molecular characterization of Corynebacterium pseudotuberculosis isolated from goats using ERIC-PCR.
Corynebacterium pseudotuberculosis, the infectious agent of caseous lymphadenitis (CLA), is responsible for substantial economic losses in goat and sheep production. Molecular characterization of C. pseudotuberculosis isolates by enterobacterial repetitive intergenic consensus (ERIC)-PCR has shown promising results in genotyping strains isolated from sheep with CLA. We evaluated the geneti...
BACKGROUND: Colibacillosis is one of the most economically important diseases of poultry worldwide. OBJECTIVES: This study was conducted to examine the clonal relatedness and typing of 95 avian Escherichia coli isolates by ERIC-PCR. METHODS: Sixty-three E. coli isolates from two common manifestations of colibacillosis (yolk sac infection and colisepticemia) and 32 isolates from feces of apparen...
This study evaluates the effectiveness of three different molecular techniques, repetitive extragenic palindromic PCR (REP-PCR), enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) and the random amplified polymorphic DNA (RAPD-PCR) for rapid typing of Photobacterium damselae ssp. piscicida strains isolated from different species of marine fish and geographic areas. The resu...
background and objectives: the emergence of plasmid-mediated ampc (pampc) β-lactamases conferring resistance to third-generation cephalosporins has become a major clinical concern worldwide. the aims of this study were to determine the prevalence of pampc-producing e. cloacae isolates and typing of them in qazvin and tehran provinces, iran. materials and methods: a total of 120 cefoxitin non-su...
shigellosis is one of the important gastrointestinal bacterial infections, particularly among children of developing countries such as iran. antibiotic susceptibility pattern and genetic typing for epidemiological purposes are of significant issues in shigella infectious control. the aim of this study was to investigate the antibiotic susceptibility and genetic relationship among shigella strai...
