Interbacterial adhesion of bacteria isolated from canine dental plaque was assessed by performing a visual coaggregation assay. Using conditions mimicking those likely to be encountered in vivo, the entire cultivable plaque microbiota from a single dog was assessed, and eight (6.7%) unique coaggregation interactions were detected for 120 crosses. Transmission electron microscopy was used to vis...
Background and Objectives:Infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. The aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (PE). Materials and Methods: In this cross sectional study, 1210 samples with exudative features were cultured for p...
Introduction: Cerumen is known as ear wax, produced regularly by cerumen and lipid secretary glands. Regarding the effect of Mazandaran province's humid weather on the prevalence of pathogenic microorganisms, this study was performed to determine the bacterial flora of the ear in patients with acute otitis externa and its comparison with healthy subjects. Materials and Methods: In this case-...
Background and Objectives: Urinary tract infections (UTI) are one of the most common infectious diseases with different microbial agent and antimicrobial resistant pattern in hospitalized patients and outpatients. In order to assess the adequacy of therapy, knowledge of prevalence and resistance pattern of the bacteria is necessary. The main aim of this study was to evaluate the prevalence and ...
background: blood stream infection is one of the main causes of morbidity and mortality in patients with cancer. the purpose of this study was to evaluate the prevalence of aerobic and anaerobic-bacteremia in hospital inpatients with cancer and to determine the antibiotic resistance profile in isolated organisms in kerman, southeast iran. methods: total of 240 blood cultures from 136 patients...
background and objectives: hospital surfaces can serve as reservoirs of potential pathogenic bacteria.staff hands are the main source of bacterial transmission in hospital. the prevalence of bacteria harboring β– lactamase enzyme in staff hands and hospital surfaces, leads to spread of β–lactamase producing bacteria and ultimate increase of antibiotic resistance nosocomial infections. the aim o...
vancomycin-resistant enterococci (vre) are becoming a major concern in medical practice. their increased prevalence and their ability to transfer vancomycin resistance to other bacteria have made them a subject of close scrutiny and intense investigation. colonization is usually acquired by susceptible hosts in an environment with a high rate of patient colonization with vre. the aim of this st...
Effects of tetracycline residues from pig manure slurry on the prevalence of tetracycline-resistant bacteria and the tetracycline resistance gene, tet(M), were studied in soil microcosms. Four types of soil microcosms were established for a period of 152 days, supplemented with combinations of pig manure slurry and a tetracycline-resistant Enterococcus faecalis, CG110, containing the tetracycli...
