Sepsis is a life-threatening infection. Escherichia coli is the first known cause of bacteremia leading to sepsis. Lymphopenia was shown to predict bacteremia better than conventional markers of infection. The pks genomic island, which is harbored by extraintestinal pathogenic E. coli (ExPEC) and encodes the genotoxin colibactin, is epidemiologically associated with bacteremia. To investigate a...

conclusions this results of the study show that the most contamination in nicus is from gram-negative bacteria and ciprofloxacin is the most effective antibiotic for treatment. thus, the control of infections in nicus in hospitals is very important. results during the seven-month study on 105 samples, including 85 (81%) urine samples and 20 (19%) blood samples, 81 samples (77.1%) were gram-nega...

neonatal sepsis is a disease of infants who are less than 1 month of age. these infants are clinically ill, and their blood culture are positive for bacteria. the reported incidence of neonatal sepsis for allinfants is 1 to 10 per 1000 live births. the mortality rate is 4.2-26%. the clinical signs are not specific and diagnosis of neonatal sepsis is one of the most difficult tasks in clinical m...

Few pathogens cause sepsis. The majority of sepsis causing bacteria is facultative anaerobes. This type of respiration is the most flexible and it facilitates pathogen survival, proliferation and dissemination in human tissues and blood. Other conditions for causing sepsis are thick slime layer and capsule, as well as production of antioxidant enzymes and substances (superoxide dismutase (SOD),...

Usually identification of the causative bacteria for an episode of sepsis is achieved using microbiological culture of blood or body fluid. In the case of pleural effusion and fever, a microscopic examination of the pleural effusion smear to identify the bacteria responsible should be performed immediately to optimize the selection of antibiotic therapy regimen.

Neonatal septicemia is the most important cause of neonatal mortality. A wide variety of bacteria both aerobic and anaerobic can cause neonatal sepsis. Genus Pantoea is a member of Enterobacteriaceae family that inhabits plants, soil and water and rarely causes human infections, however, Pantoea dispersa has not been reported as a causative organism for neonatal sepsis. We hereby report two neo...

INTRODUCTION Sepsis is an inflammatory reaction to bacteria involving the whole body and is a significant cause of mortality and economic costs. The purpose of this research was to determine whether tadalafil exhibits a preventive effect on sepsis in a septic model induced in rats with cecal ligation and puncture (CLP). MATERIALS AND METHODS Rats were randomly separated into groups, 10 rats i...

BACKGROUND Sepsis represents a substantial health care burden, and there is limited epidemiologic information about the demography of sepsis or about the temporal changes in its incidence and outcome. We investigated the epidemiology of sepsis in the United States, with specific examination of race and sex, causative organisms, the disposition of patients, and the incidence and outcome. METHO...

ARQUIVOS DE MEDICINA, 22(4/5):121-2 Amniocentesis is a safe procedure with low risk for complications including infection. A case of genetic amniocentesis followed by Escherichia coli sepsis is reported. Bacteriological data showed positive blood cultures to Escherichia coli. The mechanisms of infection are discussed: contamination from the instruments, systemic dissemination of bacteria coming...
