Andrade, Mariana; Oliveira, Ketlyn; Morais, Catarina; Abrantes, Patrícia; Pomba, Constança; Rosato, Adriana E.; Couto, Isabel; Costa, Sofia SantosCoagulase-positive staphylococci (CoPS) account for most bacteria-related pyoderma in companion animals. Emergence of methicillin-resistant strains of Staphylococcus pseudintermedius (MRSP), Staphylococcus aureus (MRSA) or Staphylococcus coagulans (MRSC), often with multidrug-resistant (MDR) phenotypes, is a public health concern. The study collection comprised 237 staphylococci (S. pseudintermedius (n = 155), ...
Staphylococcus aureus Causing Skin and Soft Tissue Infections in Companion Anim...
Costa, Sofia Santos; Ribeiro, Rute; Serrano, Maria; Oliveira, Ketlyn; Ferreira, Carolina; Leal, Marta; Pomba, Constança; Couto, IsabelStaphylococcus aureus is a relevant agent of skin and soft tissue infections (SSTIs) in animals. Fifty-five S. aureus comprising all SSTI-related isolates in companion animals, collected between 1999 and 2018 (Lab 1) or 2017 and 2018 (Lab 2), were characterized regarding susceptibility to antibiotics and heavy metals and carriage of antimicrobial resistance determinants. Clonal lineages were established by PFGE...
MRSA colonization in workers from different occupational environments
Oliveira, Ketlyn; Viegas, Carla; Ribeiro, EdnaFunding: This research was supported by Instituto Politécnico de Lisboa, Lisbon, Portugal, by funding the Projects “Occupational exposure of ambulance drivers to bioburden” (IPL/2020/BIOAmbuDrivers_ESTeSL) and “Bacterial Bioburden assessment in the context of occupational exposure and animal health of swine productions” (IPL/2016/BBIOR-Health).; Staphylococcus aureus and particularly methicillin-resistant S. au...
Clonal lineages, antimicrobial resistance, and pvl carriage of staphylococcus a...
Ferreira, Carolina; Costa, Sofia Santos; Serrano, Maria; Oliveira, Ketlyn; Trigueiro, Graça; Pomba, Constança; Couto, IsabelStaphylococcus aureus (S. aureus) is a leading cause of skin and soft-tissue infections (SSTIs) in the community. In this study, we characterized a collection of 34 S. aureus from SSTIs in ambulatory patients in Portugal and analyzed the presence of Panton–Valentine leucocidin (PVL)-encoding genes and antibiotic-resistance profile, which was correlated with genetic determinants, plasmid carriage, and clonal lin...
