Introduction Increasing numbers of patients with immunodeficiencies, malignant diseases, advanced surgeries and prolonged stays in intensive care units are at risk for developing infections by enteric bacteria, which often are systemic (sepsis) and caused by multidrug resistance isolates. Intestinal bacteria provide also a constant antigenic stimulation for the synthesis of natural anti-carbohy...
sepsis is a significant cause of morbidity and mortality in neonates. the most common pathogens of bacterial sepsis and antibiotic sensitivity patterns vary in different parts of the world. the aim of this study was to determine the most common pathogens and outcome of neonatal sepsis and also antibiotic sensitivity patterns of klebsiella species. a retrospective descriptive study was carried o...
Sepsis is initiated by interactions between microbial products and host inflammatory cells. Toll-like receptors (TLRs) are central innate immune mediators of sepsis that recognize different components of microorganisms. Peptidoglycan-associated lipoprotein (PAL) is a ubiquitous gram-negative bacterial outer-membrane protein that is shed by bacteria into the circulation of septic animals. We exp...
Bacterial sepsis is a major cause of fatality worldwide. Sepsis is a multi-step process that involves an uncontrolled inflammatory response by the host cells that may result in multi organ failure and death. Both gram-negative and gram-positive bacteria play a major role in causing sepsis. These bacteria produce a range of virulence factors that enable them to escape the immune defenses and dis...
Mammals harbor a complex gut-associated microbiota, comprising bacteria that provide immunological, metabolic and neurological benefits to the host, and contribute to their well-being. However, dysregulation of the microbiota composition, known as dysbiosis, along with the associated mucosal immune response have a key role in the pathogenesis of many inflammatory diseases, including inflammator...
Neonatal sepsis is a life-threatening emergency, and any delay in treatment may cause death. Because of the importance of the problem in Iran, the aim of this retrospective study was to determine the etiological agents of neonatal septicemia, and the prevalence and epidemiology of Klebsiella bacteremia in the neonatal wards. Two hundred and ten cases of neonatal sepsis occurred during the study...
INTRODUCTION We evaluated blood culture-proven sepsis episodes occurring in microclusters in very-low-birth-weight infants born in the German Neonatal Network (GNN) during 2009-2010. METHODS Thirty-seven centers participated in GNN; 23 centers enrolled ≥50 VLBW infants in the study period. Data quality was approved by on-site monitoring. Microclusters of sepsis were defined as occurrence of a...
BACKGROUND Bacterial sepsis is a major threat in neonates born prematurely, and is associated with elevated morbidity and mortality. Little is known on the innate immune response to bacteria among extremely premature infants. METHODOLOGY/PRINCIPAL FINDINGS We compared innate immune functions to bacteria commonly causing sepsis in 21 infants of less than 28 wks of gestational age, 24 infants b...
Sepsis, frequently caused by infection of bacteria, is considered as an uncontrollable systematic inflammation response syndrome (SIRS). Maresin 1 (Mar1) is a new proresolving mediator with potent anti-inflammatory effect in several animal models. However, its effect in sepsis is still not investigated. To address this question, we developed sepsis model in BALB/c mice by cecal ligation and pun...
OBJECTIVE To determine the etiology and clinical disease progression variables of sepsis associated with the prognosis of patients admitted to a pediatric intensive care unit. METHODS Prospective and retrospective case series. Data were collected from the medical records of patients diagnosed with sepsis who were admitted to the pediatric intensive care unit of a general hospital from January...
