background and objectives: recently, nosocomial infections have been discussed as a critical issue among intubated patients leading to significant morbidity and mortality. hence, the pattern of microbiological colonization and antibiotic resistance are much valuable in this regard. we aimed to investigate the pattern of microorganism colonization and antibiotic resistance in patients with endot...

The goal was to identify risk factors for healthcare-associated infections by resistant microorganisms and patient mortality in an Intensive Care Unit. A prospective and descriptive epidemiological research was conducted from 2005 till 2008, involving 2300 patients. Descriptive statistics, bivariate and multivariate logistic regression analysis were used. In bivariate analysis, infection caused...

OBJECTIVE To determine the prevalence of chronic colonization with methicillin-resistant Staphylococcus aureus (MRSA) in patients with cystic fibrosis, describe antibiotic sensitivity of the strains, and compare the patients' clinical characteristics with those of patients infected with methicillin-sensitive S. aureus (MSSA). PATIENTS AND METHODS Patients with chronic S. aureus colonization w...

Objective The aim of this study was to investigate the prevalence of abnormal vaginal microorganisms in pregnant women according to trimester, and to determine whether the presence of abnormal vaginal colonization is associated with higher risk of miscarriage or preterm delivery. Furthermore, we analyzed delivery outcomes according to individual microorganism species. Methods We included preg...

BACKGROUND Patients with severe chronic obstructive pulmonary disease (COPD) are at increased risk of infection by P. aeruginosa. The specific role of bronchiectasis in both infection and chronic colonization by this microorganism in COPD, however, remains ill defined.To evaluate the prevalence and risk factors for P. aeruginosa recovery from sputum in outpatients with severe COPD, characterizi...

ABSTRACT: Experiments were conducted at the Natural Energy Laboratory of Hawaii to determine the effectiveness of non-chemical techniques to control biofouling. The two techniques investigated were ultrasonic and ultraviolet. The colonization of microorganisms attracts higher order organisms; therefore, deactivation of microorganisms to prevent colony should reduce the fouling propensity. The m...

Colonization of the oropharynx by Kingella kingae is currently considered to be a prerequisite for later development of invasive infections. However, the oropharyngeal K. kingae DNA bacterial load in children with osteoarticular infections caused by this microorganism is not different than that of asymptomatic carriers.
