Review Case Reports[Listeria monocytogenes infection in pregnancy: experience of Pontificia Universidad Católica de Chile University Hospital].
Listeria monocytogenes is Gram-positive facultative intracellular pathogen often foodborne and found elsewhere. It is an uncommon cause of illness in the general population. However, it is an important cause of severe infection in neonates, pregnant women, elderly and immunosuppressed patients. ⋯ Listeriosis should be considered during the evaluation of febrile syndrome in pregnancy as this condition can be the only risk factor. Blood and amniotic fluid cultures are useful diagnostic tests. Perinatal complications remains high.

[Nosocomial bloodstream infections caused by gram-negative bacilli: epidemiology and risk factors for mortality].
Nosocomial bacteremia is a major cause of hospital infection, associated with high rate of morbidity and mortality, prolonged hospital stay and higher costs. However, few prospective studies analyse the prognostic factors associated with mortality of gramnegative rods bloodstream infections in hospital wards outside of intensive care units. A prospective/descriptive study was conducted from March to December 2006. ⋯ Bacteremia derived from a high-mortality associated septic focus (RR 4.9, IC95%> 1.3 - 18.8) and admission to intensive care unit (RR 4.78, IC95%> 1.7- 13.1) were independent variables associated with mortality. Inappropriate empirical antibiotic treatment was not associated with greater risk of mortality. Nosocomial gramnegative bloodstream infections in our series were mainly due to non-fermentative bacilli and were associated with high mortality rates when their origin was a high risk septic focus or the patient was admitted to intensive care unit.
