AbstractWe evaluated an infection control (IC) program influenced by personnel and material resource shortages on the incidence of bloodstream infections (BSI) due to carbapenem-resistantKlebsiella pneumoniae (CRKP),Acinetobacter baumannii (CRAB), andPseudomonas aeruginosa (CRPA) in an endemic region. Between January 2010 and December 2015, all BSI episodes caused by CRKP, CRAB, and CRPA were recorded. An IC bundle was implemented in January 2012. We evaluated the effect of the interventions on BSI rates between the pre-intervention (2010 –2011) and intervention (2012–2013) periods, using an interrupted time-se...

In this study, we applied three easier, faster, and cost-effective methods including PCR-based open reading frames (ORFs) typing, sequence typing of blaOXA-51-like and RAPD-PCR method to rapid typing of A. baumannii strains. Taken together in the present study the results of ORFs typing, PCR-sequencing of blaOXA-51-like genes and MLST sequence typing revealed there was a high prevalence (62%, 35/57) of ST2 as international and successful clone which detected among clinical isolates of multi-drug resistant A. baumannii with ORF pattern B and blaOXA-66 gene. Only 7% (4/57) of MDR isolates belonged to ST1 with ORF pattern A a...

Abstract Dissemination of carbapenem-resistant Acinetobacter baumannii (CRAB) is mainly due to the spread of clonal lineages, particularly those included into the clonal complexes (CC) CC1, CC2, CC15, CC25, and CC79. We evaluated the usefulness of a recently modified PCR-based trilocus sequence-based typing (m3LST) in comparison with the standard multilocus sequence typing (MSLT) of 7 housekeeping genes as per the Institute Pasteur Scheme to assign the clonal complexes in CRAB. A collection of 78 CRAB isolated from 67 different Brazilian health institutions was submitted to both methodologies, and concordance rate...

Accordingly, our study was aimed to determine the correlation between ability of biofilm formation and the frequency of biofilm related genes with antibiotic resistance phenotypes, and also the categorization of their patterns in clinical and environmental is...

CONCLUSIONS: High rate of anti-dengue IgM seropositivity was reported in our study. The environmental bacteria were predominantly isolated and identified in A. aegypti. The paratransgenic approach to control vector might be possible by spreading the genetically modified bacteria in larval habitat or shelter of adult mosquitoes. PMID: 28193261 [PubMed - in process]

Abstract BackgroundWe assessed the impact of intensified infection control measures (ICM) on colonization and infection caused by carbapenem‐resistant (CR) Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii in a Solid Organ Transplantation (SOT) Department. MethodsA quasi‐experimental methodology was followed. The study was divided in 3 periods: pre‐intervention, intervention with implementation of an ICM bundle including active surveillance program (ASP) and gradually enhanced measures, and post‐ASP without ASP. The bundle included active surveillance cultures, contact precautions, hand hyg...

Authors: Escandón-Vargas K, Reyes S, Gutiérrez S, Villegas MV Abstract INTRODUCTION: Enterobacteriaceae, Pseudomonas spp., and Acinetobacter spp. infections are major causes of morbidity and mortality, especially due to the emergence and spread of β-lactamases. Carbapenemases, which are β-lactamases with the capacity to hydrolyze or inactivate carbapenems, have become a serious concern as they have the largest hydrolytic spectrum and therefore limit the utility of most β-lactams, including the carbapenems. Areas covered: Here, we present an update of the current status of carbapenemases...

We report the findings of an active surveillance scheme for detection of asymptomatic carriers with carbapenemase-producing Gram-negative bacteria (CP-GNB) in Romanian hospitals. During a pilot study from December 2014 to May 2015, faecal cultures were screened in three hospitals (two large, one medium-size) for patients newly admitted to selected wards or inpatients transferred from other wards to an intensive-care unit. The study revealed a high prevalence of CP-GNB detected in 22/27 and 28/38 of the carbapenem non-susceptible isolates from Hospitals 1 and 3, respectively. CP-GNB identified through faecal screening inclu...
