thirty five monoconidial isolates of the fungal culture collection pyricularia grisea were examined, to identify the vegetative compatibility groups and characterize the genetic diversity of isolates as through rep-pcr genomic fingerprinting. the isolates were collected from ricefields during 1997-1999. genetic diversity of p. grisea isolates was studied as based on dna fingerprinting through r...

Introduction: The Enterococcus faecalis (E. faecalis) is the one of the pathogenic bacteria that become famous and considerable in the recent years. Here we tried to do typing the E. faecalis isolates to provide advantageous information that can help us to understand epidemiological communication between the E. faecalis isolates. Materials and methods: One hundred  E. faecalis were isolated fr...

Background & Aim: Important challenge for treatment of urinary tract infections is the spread of extended-spectrum beta-lactamases (ESBLs) producing Escherichia coli. Therefore, the frequencies of main beta-lactamase genes, resistance to beta-lactams and the ability of ESBLs production in urinary and fecal Escherichia coli of women with urinary tract infections were compared. Methods: In 60 Es...

Mirzapour S, Darvishnia M, Bazgir E, Mirzaei Najafgholi H (2020) Pathogenic variation of Didymella rabiei isolates causing Chickpea blight in three western provinces of Iran. Plant Pathology Science 9(2):1-13. DOI: 10.2982/PPS.9.2.1   Introduction: Chickpea blight, caused by Didymella rabiei, is the most limiting factor in chickpea production areas in the world, including the western province...

    Background & Aims : After Vancomycin resistant Enterococci (VRE) was first detected in the mid 1980s, VRE spread rapidly worldwide and became one of the most serious problems in many hospitals specially in hospitalized patients. Among different enterococcal species Enterococcus feacalis and Enterococus faecium are the leading causes of life threatening infections. VanA/B/C genes are respons...

Background and Objective: AmpC-type beta-lactamases have been implicated in group C of Amber, which includes EBC, CIT, MOX, FOX, DHA, and ACC. The active presence of these plasmid genes in clinical isolates of P.aeruginosa has resulted in resistance to a wide range of antibiotics. Therefore, we aimed to determine the minimum inhibitory concentrations (MIC) of different antibiotic groups in clin...

Background: The virulence of a pathogenic Vibrio cholerae is dependent on a discrete set of genetic determinants. In this study, we determined the distribution of virulence determinants among the clinical and environmental isolates of V. cholerae. Methods: The antibiotic resistance profiles of the isolates were determined using standard disk diffusion assay. PCR assay was performed to analyze t...

Ornithobacterium rhinotracheale (ORT) is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon) with or without respiratory signs were tested by taking of tracheal...

Background and Objective: One of the mechanisms involved in the resistance of Klebsiella pneumoniae to fluoroquinolones is AcrAB leakage pumps.  In this study, the prevalence of Klebsiella pneumoniae isolates with AcrAB encoding genes and the role of permeation pumps in fluoroquinolone resistance were investigated. Materials and Methods: 165 samples from patients of Kermanshah Medical Centers ...

the species of pseudomonas genus show different levels of resistance to soil's heavy metals pollution. since, there exists is a relationship between heavy metal resistance and plasmid profile of bacteria, in this study, plasmid profile of plant growth promoting rhizobacteria (pgpr) pseudomonas fluorescence isolates were studied in the presence of cadmium and zinc. the bacteria were initial...
