Clinical and epidemiological characterization of an outbreak of Serratia marcescens in a Pediatric Intensive Care Unit National Hospital of Itaugua. Paraguay. April to September 2015. Rev. Nac. (Itauguá) [online]. 2016, vol.8, n.2, pp.19-33. ISSN 2072-8174.


Serratia marcescens, Gram negative bacillus, family enterobacteriaceae; Is found in the intestinal flora of man and animals, in the environment and in reservoirs such as water, pipes, keys, in hospital supplies such as soaps and antiseptics.


to determine the presence of an outbreak, localizations, present comorbidities; Serotype of the causative agent, cut the transmission chain.


a descriptive study of an outbreak of S. marcescens in the period from April 27, 2015 to June 19, 2015. Any patient with positive culture for S. marcescens during the epidemic period was defined as the case, since No positive culture for this bacterium had been identified with such resistance in previous years of surveillance. Hypothesis: Transmission by contact, hand cover.


5 patients with S. marcescens positive cultures were identified during the epidemic period. Comorbidities were septic shock of enteral origin 1/5, heart disease / bronchiolitis 1/5, postoperative of ventricular hemorrhage 1/5, intestinal occlusion / late neonatal sepsis1 / 5. With invasive procedures such as mechanical ventilation, central venous catheter, urinary catheter 5/5, surgery 2/5, external lead catheter 1/5, broad spectrum antibiotic with 2 or more associations 4/5, average of 43 DDI . Locations: S. Traqueal 3/5, PC 2/5, liq. Peritoneal, HMC 1/5. Attack rate 9.4% (5/53), lethality 60% (3/5) Interventions: contact precautions, cohort, hospital hygiene.


outbreak of Serratia marcescens, a producer of carbapenemase, detected by active surveillance in PICU, most frequently isolated in S. tracheal and PC. It was controlled with prevention and control measures.
