A total of forty-three isolates of Ascochyta rabiei obtained from infected seeds and plants of chickpea from different areas of Kermanshah, Lorestan, Hamadan, Kordestan, and East and West Azarbaijan provinces were studied during the period 1996-1999. A rapid and simple method was developed for pathogenicity test in CDA (chickpea seed meal dextrose agar) medium. CDA medium was inoculated with di...
Avian pathogenic Escherichia coli (APEC) are responsible for wide ranges of extra-intestinal diseases in poultry including colibacillosis, cellulitis, coligranuloma and yolk sac infection. Numbers of virulence are considered important in the pathogenicity of these diseases. The aims of the present study were phylogenetic typing and virulence genes detection in Escherichia coli </em...
Background and Aims: Candida albicans as an opportunistic fungal pathogen in human is the cause of volvovaginitis candidiasis. Azole resistance is cinsiderable as worldwide problem in treatment of candidiasis. Azole resistance can occur through different mechanisms such as mutation in ERG11 gene. The aim of our study was evaluation of ERG11 gene mutations in fluconazole resistant islotes of C. ...
Background: The aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) Staphylococcus aureus. Methods: In total, 209 S. aureus isolates were collected. The antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of Clinica...
milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. conversely, it can be a vehicle for several pathogenic bacteria such as staphylococcus aureus. this study aimed to analyze the frequency of genes encoding the nine staphylococcal enterotoxins (ses) and enterotoxin gene profiles in s. aureus isolates derived from raw bovine milk....
nosocomial infections of multidrug-resistant pseudomonas aeruginosa (mdrpa) are a growing concern in hospitalized patients in burn centers. the aim of this study was to investigate the flagellin profiling and antibiotic susceptibility of p. aeruginosa isolated from burn wound infections. during 8 month study, 73 clinically p. aeruginosa isolates collected from patients hospitalized in burn ward...
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...
Abstract Background & Aims: Staphylococcus aureus is one of the most common causes of food poisoning. Methicillin resistant S. aureus usually are resistant to other antibiotics currently used for treatment. The aim of this study was determination of the prevalence of entrotoxigenic S.aureus in creamy pastries sold in Urmia and determining the rate of resistance to methicillin among the obta...
Background & Aims: Urinary tract infection (UTI) is the most common bacterial infection in renal transplant recipients. The aim of this study was to determine antimicrobial susceptibility patterns of Escherichia coli and Klebsiella pneumoniae isolates as well as determining cefotaxime Minimum Inhibitory Concentration (MIC) for obtained isolates.Materials & Methods: Escherichia coli and Klebsie...
Background and Aim: As one of the major causes of hospital and community acquired infections, Methicillin-resistant Staphylococcus aureus (MRSA) requires accurate and timely diagnosis. This study aimed to investigate the prevalence and antibiotic resistance patterns of MRSA in patients hospitalized in the Birjand-based Imam Reza hospital. Materials and Methods: In this cross-sectional study, a...
