In order to evaluate whether seagulls living on the Lisbon coastline, Portugal, might be colonized and consequently represent potential spreaders of multidrug-resistant bacteria, a total of 88 gull fecal samples were screened for detection of extended- spectrum β-lactamase (ESBL)- or carbapenemase-producing Enterobacteriaceae for methicillin-resistant Staphylococcus aureus (MRSA) and for...

Objective: The aim of the present study was to prospectively evaluate the prevalence of intestinal carriage by extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae among Portuguese students attending a Bachelors’ course in healthcare, and to determine the molecular features of ESBL-producing isolates.Methods: One-hundred and eleven faecal samples recovered from Portuguese...

Objectives: To provide, for the first time, data on the molecular epidemiology of carbapenemase-producing Klebsiella pneumoniae clinical isolates from the northern region of Portugal (Trás-os-Montes and Alto Douro).Methods: A total of 106 carbapenemase-producing K. pneumoniae isolates recovered from clinical samples and rectal swabs between January 2018 and March 2019 were included in this...

To decipher the genetics of acquisition of carbapenemase-encoding genes identified in two carbapenem-resistant Enterobacteriaceae recovered from a single patient in Portugal.Methods: Carbapenemase genes were searched by PCR assays and mating-out assays were performed to further characterize the plasmid support of the carbapenemase genes. Genetic characterization of the plasmid supports was...

AimsTo undertake a prospective analysis of the occurrence of colistin-resistant and extended-spectrum ß-lactamase (ESBL)-producing Enterobacterales colonizing pigs at two farms in Portugal, and to evaluate the putative correlations with usage of different antibiotics.Materials and methods: One hundred and two faecal samples recovered from two different Portuguese pig farms were screened for...

We aimed to provide updated epidemiologic data on carbapenem-resistant Klebsiella pneumoniae in Portugal by characterizing all isolates (N = 46) recovered during 2013– 2018 in a 123-bed hospital in Lisbon. We identified blaKPC-3 (n = 36), blaOXA-181 (n = 9), and blaGES-5 (n = 8) carbapenemase genes and observed co-occurrence of blaKPC-3 and blaGES-5 in 7 isolates. A single GES-5–producing...
