Resumen:
Background: Acinetobacter baumannii (Ab) clones I, III, and IV were recovered in several Buenos Aires City hospitals.We investigated
the prevalence of these clones with epidemic behavior (EB) in our intensive care unit (ICU) under an endemic setting and its spread.

A 10-week prospective cohort study including surveillance cultures of newly admitted patients was conducted. Air,
environment, and staff hands were weekly screened. In the seventh week, a new environmental cleaning protocol and a staff
hand hygiene reeducation program were implemented.
Results: Almost 15% of all screening samples (159/1042) were Ab positive. Up to the seventh week, carbapenem-resistant clone If
was the main one recovered from patients, environmental frequently touched surfaces (EFTS), and staff hands screening samples.
Few air samples were Ab positive. Clone I was also isolated from patients at admission. After the seventh week, a significant
reduction of EFTS contamination and of clone If isolation was observed. During the last 3 weeks, clone I was no longer isolated
from patients. Instead, the newly identified clone IVb was mainly cross transmitted. It was also recovered from staff hands and
from EFTS. In the last week, clone If was again isolated from 1 bed rail.

Conclusion: Patients with EB clones-positive culture at admission provide verification that interhospital patient transfers play a role
in these clones spread. However, subtypes such as clone If seem to be endemic in our ICU. EFTS showed to have potential for EB
clones transmission via transient staff hand carriage. Transmission did not involve airborne route. (Am J Infect Control
