Abstract: Infections caused by antimicrobial resistant microorganisms have become more prevalent in the last decades, and are part of a serious public health issue worldwide. In the neonatal intensive unit therapy (NICU), prolonged hospitalization, major use of antimicrobials and invasive procedures, along with immature immunological system, are all risk factor for multidrug-resistant microorganisms’ acquisition. The objective of this present study was to evaluate the epidemiological tendency of colonization by ESKAPE pathogens in newborns in the NICU on a 20 years period. Vigilance swabs cultures were analyzed from january 2000 to december 2019. Only the first positive culture of each NB was considered for microorganisms frequency. Amongst the most frequent microorganisms identified were Gram-negative bacilli (929/1107 – 84%). Extended spectrum Beta lactamase producing Enterobacterales (ESBL) were responsible for 753 (70%) colonization. Carbapenem resistant Enterobacterales was seen in smaller frequency (2%). The mean of incidence density of ESBL Klebsiella pneumoniae during the period were 2.3/1.000 patients-days, and it variated from zero in 2000 to 5 in 2013, 2015, 2018 and 2019. Amongst Gram positive cocci, the most frequent were methicillin resistant Staphylococcus aureus (MRSA), with 11%, and vancomycin-resistant Enterococcus faecium (VRE), in 5% of the vigilance cultures. The pathogens incidence of ESKAPE group were elevated in 20 years, and K. pneumonie was the most frequent colonizing pathogen in NB. Considering that colonization usually precedes infection, and there is high mortality associated with multidrug-resistant microorganisms, the elevated frequency of the ESKAPE group is quite worrying and requires control and preventive measures.
