background and objectives: blood stream infections cause significant morbidity and mortality in the world. in this study, we aimed at describing the organisms responsible for septicemia in 2006-2007 and their antimicrobial susceptibility that might lead to proper selection of antimicrobial agents in hospitalized patients with suspected sepsis. materials and methods: microbiology reports of 1753...

Since many pathogenic organisms gain access to the blood stream during the initial and acute*stages of bacterial infections, their isolation from the blood constitutes an. important diagnostic procedure. Many of these organisms have been found to vary considerably in their nutritional requirements; hence the selection of suitable media for their primaiy isolation becomes Particularly important....

Prediction of nosocomial infections among patients is an important part of clinical surveillance programs to enable the related personnel to take preventive actions in advance. Designing a clinical surveillance program with capability of predicting nosocomial infections is a challenging task due to several reasons, including high dimensionality of medical data, heterogenous data representation,...

BACKGROUND Invasive methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) infections are major causes of numerous neonatal intensive care unit (NICU) outbreaks. There have been increasing reports of MRSA outbreaks in various neonatal intensive care units (NICUs) over the last decade. Our objective was to review the experience of Staphylococcus...

OBJECTIVE To carry out surveillance of central line associated bloodstream infections in a Pediatric intensive care unit (PICU) and determine associated risk factors. METHODS This prospective study was conducted over 1.5 years in the PICU. CDC definitions for these infections were followed and associated risk factors were identified. RESULTS Of 265 enrolled children with central line, 13 de...

conclusions non-albicans candida should be considered as significant pathogens in burned patients with candidemia. results twenty-seven samples (6.7%) of the blood cultures from 13 patients (12%) were positive for candida species. candida parapsilosis (38%) and c. tropicalis (38%) were the most commonly found candida species, followed by c. albicans (15%) and c. guilliermondii (15%) in the pati...

Groups of CD-1 mice were immunized with vaccines prepared from freeze-thawed or ultra-sonicated epimastigotes, blood trypomastigotes, or "plasma antigen", of Trypanosoma cruzi strains Y, M1 and Tulahuen. The mice were challenged by the injection of blood stream trypomastigotes obtained from mice, or of metacyclic trypomastigotes harvested from the rectum of Rhodnius prolixus. Both challenges in...
