StaphNET South America: 

Establishing a network for

genomic surveillance of Staphylococcus aureus in

South America

8 & 9 October 2018
School of Pharmacy and Biochemistry, 
Universidad de Buenos Aires,
Ciudad Autónoma de Buenos Aires, Argentina

The Meeting


The meeting will bring together experts in Staphylococcus aureus from South America and worldwide, who will present on the current landscape of surveillance and research in each country or institution with a focus on the experiences, challenges, and gaps that need addressing. The meeting will include a session to assess the possibility of retrospective/prospective WGS studies of S. aureus isolates from participating countries, with consideration of current resources and abilities to deliver strains and/or genomic DNA to a central resource (CGPS-WTSI). Previous applications of WGS of S. aureus worldwide will be presented and discussed in this context. It is expected that the identification of follow-up funding will be a topic for discussion.

  1. To consolidate a network of researchers working on Staphylococcus aureus in South America, in particular in the “Cono Sur”

  2. To evaluate the feasibility of prospective genomic surveillance of Staphylococcus aureus disease in South America

  3. To ascertain the current landscape of genomics in the region, and identify needs for capacity building in sequencing and bioinformatic analysis of Staphylococcus aureus in South America

  4. To assess the feasibility and design of a retrospective genomic epidemiology study of Staphylococcus aureus in South America, and/or a prospective structured survey

  5. To identify sources of funding to support surveillance and research activities conducted by the network

Ongoing Project 2019

prospective observational study of genomic surveillance of S. aureus strains of causing bacteremia will be conducted in 74  hospitals from Argentina, Brazil, Uruguay, Paraguay, and Bolivia during 2019. The whole genomes of the strains will be sequenced and analyzed to determine their population structure and regional variability by comparison with regional and globally available data.

 The Microreact Project below shows all the participating hospitals.
