High colonization rate and heterogeneity of ESBL- and carbapenemase-producing enterobacteriaceae isolated from gull feces in Lisbon, Portugal

Aires-de-Sousa, Marta ; Fournier, Claudine ; Lopes, Elizeth ; Lencastre, Hermínia de ; Nordmann, Patrice ; Poirel, Laurent

In: Microorganisms, 2020, vol. 8, no. 10, p. 1487

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...

A new species of the large-headed coastal marine turtle Solnhofia (Testudinata, Thalassochelydia) from the Late Jurassic of NW Switzerland

Anquetin, Jérémy ; Püntener, Christian

In: PeerJ, 2020, vol. 8, p. e9931

Background: The large-headed turtle Solnhofia parsonsi is known by a handful of specimens from the Late Jurassic of Germany and Switzerland (maybe also France). Solnhofia parsonsi is traditionally regarded as a “eurysternid” Thalassochelydia, a group of small to medium sized, mostly lagoonal or marginal turtles found almost exclusively in the Late Jurassic of Europe. More recently,...

New material of “Eurysternidae” (Thalassochelydia, Pan-Cryptodira) from the Kimmeridgian of the Swiss Jura Mountains

Püntener, Christian ; Anquetin, Jérémy ; Billon-Bruyat, Jean-Paul

In: Palaeovertebrata, 2020, vol. 43, no. 1, p. e2

The region of Porrentruy (Swiss Jura Mountains) is known for its rich and diverse assemblage of Late Jurassic coastal marine turtles (Thalassochelydia). Dominated by the “Plesiochelyidae”, this assemblage also includes representatives of the two other thalassochelydian groups, the “Thalassemydidae” and “Eurysternidae.” In this study, we present new shell-based material from Porrentruy...

Occurrence of NDM-1-producing Morganella morganii and Proteus mirabilis in a single patient in Portugal: probable in vivo transfer by conjugation

Aires-de-Sousa, Marta ; Ortiz de la Rosa, José Manuel ; Goncalves, Maria Luísa ; Costa, Augusto ; Nordmann, Patrice ; Poirel, Laurent

In: Journal of Antimicrobial Chemotherapy, 2020, vol. 75, no. 4, p. 903–906

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...

Occurrence of CTX-M-15- and MCR-1-producing Enterobacterales in pigs in Portugal: evidence of direct links with antibiotic selective pressure

Fournier, Claudine ; Aires-de-Sousa, Marta ; Nordmann, Patrice ; Poirel, Laurent

In: International Journal of Antimicrobial Agents, 2020, vol. 55, no. 2, p. 105802

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...

Epidemiology of Carbapenemase-Producing Klebsiella pneumoniae in a Hospital, Portugal

Aires-de-Sousa, Marta ; Ortiz de la Rosa, José Manuel ; Gonçalves, Maria Luísa ; Pereira, Ana Luísa ; Nordmann, Patrice ; Poirel, Laurent

In: Emerging Infectious Diseases, 2019, vol. 25, no. 9, p. 1632–1638

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...

Novel insights into the morphology of Plesiochelys bigleri from the early Kimmeridgian of Northwestern Switzerland

Raselli, Irena ; Anquetin, Jérémy

In: PLOS ONE, 2019, vol. 14, no. 5, p. e0214629

Plesiochelyidae were relatively large coastal marine turtles, which inhabited the epicontinental seas of Western Europe during the Late Jurassic. Their fossil record can be tracked in Germany, Switzerland, the United Kingdom, France, Spain and Portugal. The Jura Mountains, in northwestern Switzerland, have been the main source for the study of this group, mostly thanks to the rich and famous...
