BACKGROUND AND THE PURPOSE OF THE STUDY Bifidobacterial strains are excessively sensitive to acidic conditions and this can affect their living ability in the stomach and fermented foods, and as a result, restrict their use as live probiotic cultures. The aim of the present study was to obtain bifidobacterial isolates with augmented tolerance to simulated(More)
BACKGROUND Acinetobacter baumannii plays an important role in some types of nosocomial infections as an opportunist microorganism which increases levels of resistance to antibacterial drugs and disinfectants. OBJECTIVES The aim of this study was to determine the resistance and sensitivity of A. baumannii to different antibiotics and evaluate the minimal(More)
INTRODUCTION Antiseptics and disinfectants have been used widely in hospitals and other health care settings to control the growth of microorganisms. However, some disinfectant resistant strains were reported. The objectives of our study were to evaluate correlation between the efflux pump genes, drugs and disinfectant resistant among clinical isolates of(More)
Recently, the quick spreads of broad-spectrum beta-lactams antibiotic resistance in pathogenic strains of bacteria have become a major global health problem. These new emerging resistances cause ineffectiveness of antibiotics and increasing the severity of diseases and treatment costs. Among different and diverse resistance targets, we chose a class A beta(More)
Background: Nowadays the molecular methods widely use for rapid identification of Mycobacterium other than tuberculosis (MOTT). The Mycobacterium simiae isolates are cause of majority of human pulmonary diseases compared with other atypical mycobacteria. As sensitivity of primers and digestion patterns for diversified fragments is different, this survey(More)
BACKGROUND The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. METHODS S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3(More)
OBJECTIVE Pyocyanine plays an important role in the pathogenesis of Pseudomonas aeruginosa, (P. aeruginosa) and is known to have inhibitory and bactericidal effects. This study has aimed to detect the phenazine biosynthetic operon (phz ABCDEFG) and two phenazine modifying genes (phzM and phzS) by polymerase chain reaction (PCR) and detection of its possible(More)
Received: 25/Nov/2007, Accepted: 6/Feb/2008 Objective: The objective of this research was to determine the prevalence of genital C. trachomatis infection in asymptomatic women by using highly sensitive nested-polymerase chain reaction (PCR) in urine sample. Materials and Methods: One hundred-forty asymptomatic women were randomly selected from those who(More)
The aim of this study was to evaluate the susceptibility of Klebsiella pneumoniae clinical isolates to antibiotics and to a quaternary ammonium compound (QAC) disinfectant as the concentrations used clinically and to determine the presence of the qacEΔ1 and cepA genes for the first time in Iran. In total, 85 K. pneumoniae isolates were randomly collected(More)
